Configuration

Now that you’ve successfully logged into your Dataverse installation with a superuser account after going through a basic Installation, you’ll need to secure and configure your installation.

Settings within your Dataverse installation itself are managed via JVM options or by manipulating values in the setting table directly or through API calls.

Once you have finished securing and configuring your Dataverse installation, you may proceed to the Admin Guide for more information on the ongoing administration of a Dataverse installation. Advanced configuration topics are covered in the Shibboleth and OAuth Login Options sections.

Securing Your Installation

Changing the Superuser Password

The default password for the “dataverseAdmin” superuser account is “admin”, as mentioned in the Installation section, and you should change it, of course.

Blocking API Endpoints

The Native API contains a useful but potentially dangerous API endpoint called “admin” that allows you to change system settings, make ordinary users into superusers, and more. The “builtin-users” endpoint lets admins create a local/builtin user account if they know the key defined in BuiltinUsers.KEY.

By default, most APIs can be operated on remotely and a number of endpoints do not require authentication. The endpoints “admin” and “builtin-users” are limited to localhost out of the box by the settings :BlockedApiEndpoints and :BlockedApiPolicy.

It is very important to keep the block in place for the “admin” endpoint, and to leave the “builtin-users” endpoint blocked unless you need to access it remotely. Documentation for the “admin” endpoint is spread across the Native API section of the API Guide and the Admin Guide.

It’s also possible to prevent file uploads via API by adjusting the :UploadMethods database setting.

Forcing HTTPS

To avoid having your users send credentials in the clear, it’s strongly recommended to force all web traffic to go through HTTPS (port 443) rather than HTTP (port 80). The ease with which one can install a valid SSL cert into Apache compared with the same operation in Payara might be a compelling enough reason to front Payara with Apache. In addition, Apache can be configured to rewrite HTTP to HTTPS with rules such as those found at https://wiki.apache.org/httpd/RewriteHTTPToHTTPS or in the section on Shibboleth.

Recording User IP Addresses

By default, the Dataverse installation captures the IP address from which requests originate. This is used for multiple purposes including controlling access to the admin API, IP-based user groups and Make Data Count reporting. When the Dataverse installation is configured behind a proxy such as a load balancer, this default setup may not capture the correct IP address. In this case all the incoming requests will be logged in the access logs, MDC logs etc., as if they are all coming from the IP address(es) of the load balancer itself. Proxies usually save the original address in an added HTTP header, from which it can be extracted. For example, AWS LB records the “true” original address in the standard X-Forwarded-For header. If your Dataverse installation is running behind an IP-masking proxy, but you would like to use IP groups, or record the true geographical location of the incoming requests with Make Data Count, you may enable the IP address lookup from the proxy header using the JVM option dataverse.useripaddresssourceheader, described further below.

Before doing so however, you must absolutely consider the security risks involved! This option must be enabled only on a Dataverse installation that is in fact fully behind a proxy that properly, and consistently, adds the X-Forwarded-For (or a similar) header to every request it forwards. Consider the implications of activating this option on a Dataverse installation that is not running behind a proxy, or running behind one, but still accessible from the insecure locations bypassing the proxy: Anyone can now add the header above to an incoming request, supplying an arbitrary IP address that the Dataverse installation will trust as the true origin of the call. Thus giving an attacker an easy way to, for example, get in a privileged IP group. The implications could be even more severe if an attacker were able to pretend to be coming from localhost, if a Dataverse installation is configured to trust localhost connections for unrestricted access to the admin API! We have addressed this by making it so that Dataverse installation should never accept localhost, 127.0.0.1, 0:0:0:0:0:0:0:1 etc. when supplied in such a header. But if you have reasons to still find this risk unacceptable, you may want to consider turning open localhost access to the API off (See Securing Your Installation for more information.)

This is how to verify that your proxy or load balancer, etc. is handling the originating address headers properly and securely: Make sure access logging is enabled in your application server (Payara) configuration. (<http-service access-logging-enabled="true"> in the domain.xml). Add the address header to the access log format. For example, on a system behind AWS ELB, you may want to use something like %client.name% %datetime% %request% %status% %response.length% %header.referer% %header.x-forwarded-for%. Once enabled, access the Dataverse installation from outside the LB. You should now see the real IP address of your remote client in the access log. For example, something like: "1.2.3.4" "01/Jun/2020:12:00:00 -0500" "GET /dataverse.xhtml HTTP/1.1" 200 81082  "NULL-REFERER" "128.64.32.16"

In this example, 128.64.32.16 is your remote address (that you should verify), and 1.2.3.4 is the address of your LB. If you’re not seeing your remote address in the log, do not activate the JVM option! Also, verify that all the entries in the log have this header populated. The only entries in the access log that you should be seeing without this header (logged as "NULL-HEADER-X-FORWARDED-FOR") are local requests, made from localhost, etc. In this case, since the request is not coming through the proxy, the local IP address should be logged as the primary one (as the first value in the log entry, %client.name%). If you see any requests coming in from remote, insecure subnets without this header - do not use the JVM option!

Once you are ready, enable the JVM option. Verify that the remote locations are properly tracked in your MDC metrics, and/or your IP groups are working. As a final test, if your Dataverse installation is allowing unrestricted localhost access to the admin API, imitate an attack in which a malicious request is pretending to be coming from 127.0.0.1. Try the following from a remote, insecure location:

curl https://your.dataverse.edu/api/admin/settings --header "X-FORWARDED-FOR: 127.0.0.1"

First of all, confirm that access is denied! If you are in fact able to access the settings api from a location outside the proxy, something is seriously wrong, so please let us know, and stop using the JVM option. Otherwise check the access log entry for the header value. What you should see is something like "127.0.0.1, 128.64.32.16". Where the second address should be the real IP of your remote client. The fact that the “fake” 127.0.0.1 you sent over is present in the header is perfectly ok. This is the proper proxy behavior - it preserves any incoming values in the X-Forwarded-Header, if supplied, and adds the detected incoming address to it, on the right. It is only this rightmost comma-separated value that Dataverse installation should ever be using.

Still feel like activating this option in your configuration? - Have fun and be safe!

Privacy Considerations

Email Privacy

Out of the box, your Dataverse installation will list email addresses of the contacts for datasets when users visit a dataset page and click the “Export Metadata” button. Additionally, out of the box, the Dataverse installation will list email addresses of Dataverse collection contacts via API (see View a Dataverse Collection in the Native API section of the API Guide). If you would like to exclude these email addresses from export, set :ExcludeEmailFromExport to true.

Additional Recommendations

Run Payara as a User Other Than Root

See the Payara section of Prerequisites for details and init scripts for running Payara as non-root.

Related to this is that you should remove /root/.payara/pass to ensure that Payara isn’t ever accidentally started as root. Without the password, Payara won’t be able to start as root, which is a good thing.

Enforce Strong Passwords for User Accounts

Your Dataverse installation only stores passwords (as salted hash, and using a strong hashing algorithm) for “builtin” users. You can increase the password complexity rules to meet your security needs. If you have configured your Dataverse installation to allow login from remote authentication providers such as Shibboleth, ORCID, GitHub or Google, you do not have any control over those remote providers’ password complexity rules. See the Auth Modes: Local vs. Remote vs. Both section below for more on login options.

Even if you are satisfied with the out-of-the-box password complexity rules the Dataverse Software ships with, for the “dataverseAdmin” account you should use a strong password so the hash cannot easily be cracked through dictionary attacks.

Password complexity rules for “builtin” accounts can be adjusted with a variety of settings documented below. Here’s a list:

Network Ports

Remember how under “Decisions to Make” in the Preparation section we mentioned you’ll need to make a decision about whether or not to introduce a proxy in front of the Dataverse Software such as Apache or nginx? The time has come to make that decision.

The need to redirect port HTTP (port 80) to HTTPS (port 443) for security has already been mentioned above and the fact that Payara puts these services on 8080 and 8181, respectively, was touched on in the Installation section. In production, you don’t want to tell your users to use your Dataverse installation on ports 8080 and 8181. You should have them use the standard HTTPS port, which is 443.

Your decision to proxy or not should primarily be driven by which features of the Dataverse Software you’d like to use. If you’d like to use Shibboleth, the decision is easy because proxying or “fronting” Payara with Apache is required. The details are covered in the Shibboleth section.

Even if you have no interest in Shibboleth, you may want to front your Dataverse installation with Apache or nginx to simply the process of installing SSL certificates. There are many tutorials on the Internet for adding certs to Apache, including a some notes used by the Dataverse Project team, but the process of adding a certificate to Payara is arduous and not for the faint of heart. The Dataverse Project team cannot provide much help with adding certificates to Payara beyond linking to tips on the web.

Still not convinced you should put Payara behind another web server? Even if you manage to get your SSL certificate into Payara, how are you going to run Payara on low ports such as 80 and 443? Are you going to run Payara as root? Bad idea. This is a security risk. Under “Additional Recommendations” under “Securing Your Installation” above you are advised to configure Payara to run as a user other than root.

There’s also the issue of serving a production-ready version of robots.txt. By using a proxy such as Apache, this is a one-time “set it and forget it” step as explained below in the “Going Live” section.

If you are convinced you’d like to try fronting Payara with Apache, the Shibboleth section should be good resource for you.

If you really don’t want to front Payara with any proxy (not recommended), you can configure Payara to run HTTPS on port 443 like this:

./asadmin set server-config.network-config.network-listeners.network-listener.http-listener-2.port=443

What about port 80? Even if you don’t front your Dataverse installation with Apache, you may want to let Apache run on port 80 just to rewrite HTTP to HTTPS as described above. You can use a similar command as above to change the HTTP port that Payara uses from 8080 to 80 (substitute http-listener-1.port=80). Payara can be used to enforce HTTPS on its own without Apache, but configuring this is an exercise for the reader. Answers here may be helpful: http://stackoverflow.com/questions/25122025/glassfish-v4-java-7-port-unification-error-not-able-to-redirect-http-to

If you are running an installation with Apache and Payara on the same server, and would like to restrict Payara from responding to any requests to port 8080 from external hosts (in other words, not through Apache), you can restrict the AJP listener to localhost only with:

./asadmin set server-config.network-config.network-listeners.network-listener.http-listener-1.address=127.0.0.1

You should NOT use the configuration option above if you are running in a load-balanced environment, or otherwise have the web server on a different host than the application server.

Root Dataverse Collection Permissions

The user who creates a Dataverse collection is given the “Admin” role on that Dataverse collection. The root Dataverse collection is created automatically for you by the installer and the “Admin” is the superuser account (“dataverseAdmin”) we used in the Installation section to confirm that we can log in. These next steps of configuring the root Dataverse collection require the “Admin” role on the root Dataverse collection, but not the much more powerful superuser attribute. In short, users with the “Admin” role are subject to the permission system. A superuser, on the other hand, completely bypasses the permission system. You can give non-superusers the “Admin” role on the root Dataverse collection if you’d like them to configure the root Dataverse collection.

In order for non-superusers to start creating Dataverse collections or datasets, you need click “Edit” then “Permissions” and make choices about which users can add Dataverse collections or datasets within the root Dataverse collection. (There is an API endpoint for this operation as well.) Again, the user who creates a Dataverse collection will be granted the “Admin” role on that Dataverse collection. Non-superusers who are not “Admin” on the root Dataverse collection will not be able to do anything useful until the root Dataverse collection has been published.

As the person installing the Dataverse Software, you may or may not be a local metadata expert. You may want to have others sign up for accounts and grant them the “Admin” role at the root Dataverse collection to configure metadata fields, templates, browse/search facets, guestbooks, etc. For more on these topics, consult the Dataverse Collection Management section of the User Guide.

Persistent Identifiers and Publishing Datasets

Persistent identifiers are a required and integral part of the Dataverse Software. They provide a URL that is guaranteed to resolve to the datasets or files they represent. The Dataverse Software currently supports creating identifiers using DOI and Handle.

By default, the installer configures a default DOI namespace (10.5072) with DataCite as the registration provider. Please note that as of the release 4.9.3, we can no longer use EZID as the provider. Unlike EZID, DataCite requires that you register for a test account, configured with your own prefix (please contact support@datacite.org). Once you receive the login name, password, and prefix for the account, configure the credentials in your domain.xml, as the following two JVM options:

<jvm-options>-Ddoi.username=...</jvm-options>
<jvm-options>-Ddoi.password=...</jvm-options>

and restart Payara. The prefix can be configured via the API (where it is referred to as “Authority”):

curl -X PUT -d 10.xxxx http://localhost:8080/api/admin/settings/:Authority

Once this is done, you will be able to publish datasets and files, but the persistent identifiers will not be citable, and they will only resolve from the DataCite test environment (and then only if the Dataverse installation from which you published them is accessible - DOIs minted from your laptop will not resolve). Note that any datasets or files created using the test configuration cannot be directly migrated and would need to be created again once a valid DOI namespace is configured.

To properly configure persistent identifiers for a production installation, an account and associated namespace must be acquired for a fee from a DOI or HDL provider. DataCite (https://www.datacite.org) is the recommended DOI provider (see https://dataverse.org/global-dataverse-community-consortium for more on joining DataCite) but EZID (http://ezid.cdlib.org) is an option for the University of California according to https://www.cdlib.org/cdlinfo/2017/08/04/ezid-doi-service-is-evolving/ . Handle.Net (https://www.handle.net) is the HDL provider.

Once you have your DOI or Handle account credentials and a namespace, configure your Dataverse installation to use them using the JVM options and database settings below.

Configuring Your Dataverse Installation for DOIs

By default, your Dataverse installation attempts to register DOIs for each dataset and file under a test authority, though you must apply for your own credentials as explained above.

Here are the configuration options for DOIs:

JVM Options:

Database Settings:

Configuring Your Dataverse Installation for Handles

Here are the configuration options for handles:

Note: If you are minting your own handles and plan to set up your own handle service, please refer to Handle.Net documentation.

Auth Modes: Local vs. Remote vs. Both

There are three valid configurations or modes for authenticating users to your Dataverse installation:

Local Only Auth

Out of the box, your Dataverse installation is configured in “local only” mode. The “dataverseAdmin” superuser account mentioned in the Installation section is an example of a local account. Internally, these accounts are called “builtin” because they are built in to the Dataverse Software application itself.

Both Local and Remote Auth

The authenticationproviderrow database table controls which “authentication providers” are available within a Dataverse installation. Out of the box, a single row with an id of “builtin” will be present. For each user in a Dataverse installation, the authenticateduserlookup table will have a value under authenticationproviderid that matches this id. For example, the default “dataverseAdmin” user will have the value “builtin” under authenticationproviderid. Why is this important? Users are tied to a specific authentication provider but conversion mechanisms are available to switch a user from one authentication provider to the other. As explained in the Account Creation + Management section of the User Guide, a graphical workflow is provided for end users to convert from the “builtin” authentication provider to a remote provider. Conversion from a remote authentication provider to the builtin provider can be performed by a sysadmin with access to the “admin” API. See the Native API section of the API Guide for how to list users and authentication providers as JSON.

Adding and enabling a second authentication provider (Add Authentication Provider and Enable or Disable an Authentication Provider) will result in the Log In page showing additional providers for your users to choose from. By default, the Log In page will show the “builtin” provider, but you can adjust this via the :DefaultAuthProvider configuration option. Further customization can be achieved by setting :AllowSignUp to “false”, thus preventing users from creating local accounts via the web interface. Please note that local accounts can also be created through the API by enabling the builtin-users endpoint (:BlockedApiEndpoints) and setting the BuiltinUsers.KEY database setting (BuiltinUsers.KEY).

To configure Shibboleth see the Shibboleth section and to configure OAuth see the OAuth Login Options section.

Remote Only Auth

As for the “Remote only” authentication mode, it means that:

  • Shibboleth or OAuth has been enabled.

  • :AllowSignUp is set to “false” to prevent users from creating local accounts via the web interface.

  • :DefaultAuthProvider has been set to use the desired authentication provider

  • The “builtin” authentication provider has been disabled (Enable or Disable an Authentication Provider). Note that disabling the “builtin” authentication provider means that the API endpoint for converting an account from a remote auth provider will not work. Converting directly from one remote authentication provider to another (i.e. from GitHub to Google) is not supported. Conversion from remote is always to “builtin”. Then the user initiates a conversion from “builtin” to remote. Note that longer term, the plan is to permit multiple login options to the same Dataverse installation account per https://github.com/IQSS/dataverse/issues/3487 (so all this talk of conversion will be moot) but for now users can only use a single login option, as explained in the Account Creation + Management section of the User Guide. In short, “remote only” might work for you if you only plan to use a single remote authentication provider such that no conversion between remote authentication providers will be necessary.

File Storage: Using a Local Filesystem and/or Swift and/or object stores

By default, a Dataverse installation stores all data files (files uploaded by end users) on the filesystem at /usr/local/payara5/glassfish/domains/domain1/files. This path can vary based on answers you gave to the installer (see the Running the Dataverse Software Installer section of the Installation Guide) or afterward by reconfiguring the dataverse.files.\<id\>.directory JVM option described below.

A Dataverse installation can alternately store files in a Swift or S3-compatible object store, and can now be configured to support multiple stores at once. With a multi-store configuration, the location for new files can be controlled on a per-Dataverse collection basis.

The following sections describe how to set up various types of stores and how to configure for multiple stores.

Multi-store Basics

To support multiple stores, a Dataverse installation now requires an id, type, and label for each store (even for a single store configuration). These are configured by defining two required jvm options:

./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.<id>.type=<type>"
./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.<id>.label=<label>"

Out of the box, a Dataverse installation is configured to use local file storage in the ‘file’ store by default. You can add additional stores and, as a superuser, configure specific Dataverse collections to use them (by editing the ‘General Information’ for the Dataverse collection as described in the Managing Datasets and Dataverse Collections section).

Note that the “-Ddataverse.files.directory”, if defined, continues to control where temporary files are stored (in the /temp subdir of that directory), independent of the location of any ‘file’ store defined above.

If you wish to change which store is used by default, you’ll need to delete the existing default storage driver and set a new one using jvm options.

./asadmin $ASADMIN_OPTS delete-jvm-options "-Ddataverse.files.storage-driver-id=file"
./asadmin $ASADMIN_OPTS create-jvm-options "-Ddataverse.files.storage-driver-id=<id>"

It is also possible to set maximum file upload size limits per store. See the :MaxFileUploadSizeInBytes setting below.

File Storage

File stores have one option - the directory where files should be stored. This can be set using

./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.<id>.directory=<file directory>"

Multiple file stores should specify different directories (which would nominally be the reason to use multiple file stores), but one may share the same directory as “-Ddataverse.files.directory” option - this would result in temp files being stored in the /temp subdirectory within the file store’s root directory.

Swift Storage

Rather than storing data files on the filesystem, you can opt for an experimental setup with a Swift Object Storage backend. Each dataset that users create gets a corresponding “container” on the Swift side, and each data file is saved as a file within that container.

In order to configure a Swift installation, you need to complete these steps to properly modify the JVM options:

First, run all the following create commands with your Swift endpoint information and credentials:

./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.<id>.type=swift"
./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.<id>.defaultEndpoint=endpoint1"
./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.<id>.authType.endpoint1=your-auth-type"
./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.<id>.authUrl.endpoint1=your-auth-url"
./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.<id>.tenant.endpoint1=your-tenant-name"
./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.<id>.username.endpoint1=your-username"
./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.<id>.endpoint.endpoint1=your-swift-endpoint"

auth_type can either be keystone, keystone_v3, or it will assumed to be basic. auth_url should be your keystone authentication URL which includes the tokens (e.g. for keystone, https://openstack.example.edu:35357/v2.0/tokens and for keystone_v3, https://openstack.example.edu:35357/v3/auth/tokens). swift_endpoint is a URL that looks something like http://rdgw.swift.example.org/swift/v1.

Then create a password alias by running (without changes):

./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.swift.password.endpoint1='\${ALIAS=swiftpassword-alias}'"
./asadmin $ASADMIN_OPTS create-password-alias swiftpassword-alias

The second command will trigger an interactive prompt asking you to input your Swift password.

Second, update the JVM option dataverse.files.storage-driver-id by running the delete command:

./asadmin $ASADMIN_OPTS delete-jvm-options "\-Ddataverse.files.storage-driver-id=file"

Then run the create command:

./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.storage-driver-id=swift"

You also have the option to set a custom container name separator. It is initialized to _, but you can change it by running the create command:

./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.swift.folderPathSeparator=-"

By default, your Swift installation will be public-only, meaning users will be unable to put access restrictions on their data. If you are comfortable with this level of privacy, the final step in your setup is to set the :PublicInstall setting to true.

In order to enable file access restrictions, you must enable Swift to use temporary URLs for file access. To enable usage of temporary URLs, set a hash key both on your swift endpoint and in your swift.properties file. You can do so by running the create command:

./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.swift.hashKey.endpoint1=your-hash-key"

You also have the option to set a custom expiration length, in seconds, for a generated temporary URL. It is initialized to 60 seconds, but you can change it by running the create command:

./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.swift.temporaryUrlExpiryTime=3600"

In this example, you would be setting the expiration length for one hour.

Setting up Compute with Swift

Once you have configured a Swift Object Storage backend, you also have the option of enabling a connection to a computing environment. To do so, you need to configure the database settings for :ComputeBaseUrl and :CloudEnvironmentName.

Once you have set up :ComputeBaseUrl properly in both the Dataverse installation and your cloud environment, validated users will have three options for accessing the computing environment:

  • Compute on a single dataset

  • Compute on multiple datasets

  • Compute on a single datafile

The compute tool options on dataset and file pages will link validated users to your computing environment. If a user is computing on one dataset, the compute tool option will redirect to:

:ComputeBaseUrl?datasetPersistentId

If a user is computing on multiple datasets, the compute tool option will redirect to:

:ComputeBaseUrl/multiparty?datasetPersistentId&anotherDatasetPersistentId&anotherDatasetPersistentId&...

If a user is computing on a single file, depending on the configuration of your installation, the compute tool option will either redirect to:

:ComputeBaseUrl?datasetPersistentId=yourObject

if your installation’s :PublicInstall setting is true, or:

:ComputeBaseUrl?datasetPersistentId=yourObject&temp_url_sig=yourTempUrlSig&temp_url_expires=yourTempUrlExpiry

You can configure this redirect properly in your cloud environment to generate a temporary URL for access to the Swift objects for computing.

Amazon S3 Storage (or Compatible)

The Dataverse Software supports Amazon S3 storage as well as other S3-compatible stores (like Minio, Ceph RADOS S3 Gateway and many more) for files uploaded to your Dataverse installation.

The Dataverse Software S3 driver supports multi-part upload for large files (over 1 GB by default - see the min-part-size option in the table below to change this).

Note: The Dataverse Project Team is most familiar with AWS S3, and can provide support on its usage with the Dataverse Software. Thanks to community contributions, the application’s architecture also allows non-AWS S3 providers. The Dataverse Project Team can provide very limited support on these other providers. We recommend reaching out to the wider Dataverse Project Community if you have questions.

First: Set Up Accounts and Access Credentials

The Dataverse Software and the AWS SDK make use of the “AWS credentials profile file” and “AWS config profile file” located in ~/.aws/ where ~ is the home directory of the user you run Payara as. This file can be generated via either of two methods described below:

  1. Manually through creation of the credentials and config files or

  2. Automatically via the AWS console commands.

Some usage scenarios might be eased without generating these files. You may also provide static credentials via MicroProfile Config, see below.

Preparation When Using Amazon’s S3 Service

You’ll need an AWS account with an associated S3 bucket for your installation to use. From the S3 management console (e.g. https://console.aws.amazon.com/), you can poke around and get familiar with your bucket.

Make note of the bucket’s name and the region its data is hosted in.

To create a user with full S3 access and nothing more for security reasons, we recommend using IAM (Identity and Access Management). See IAM User Guide for more info on this process.

Generate the user keys needed for a Dataverse installation afterwards by clicking on the created user. (You can skip this step when running on EC2, see below.)

Tip

If you are hosting your Dataverse installation on an AWS EC2 instance alongside storage in S3, it is possible to use IAM Roles instead of the credentials file (the file at ~/.aws/credentials mentioned below). Please note that you will still need the ~/.aws/config file to specify the region. For more information on this option, see http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html

Preparation When Using Custom S3-Compatible Service

We assume you have your S3-compatible custom storage in place, up and running, ready for service.

Please make note of the following details:

  • Endpoint URL - consult the documentation of your service on how to find it.

  • Region: Optional, but some services might use it. Consult your service documentation.

    • Example: us-east-1

  • Access key ID and secret access key: Usually you can generate access keys within the user profile of your service.

    • Example:

      • ID: Q3AM3UQ867SPQQA43P2F

      • Key: zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG

  • Bucket name: The Dataverse installation will fail opening and uploading files on S3 if you don’t create one.

    • Example: dataverse

Manually Set Up Credentials File

To create the ~/.aws/credentials file manually, you will need to generate a key/secret key (see above). Once you have acquired the keys, they need to be added to the credentials file. The format for credentials is as follows:

[default]
aws_access_key_id = <insert key, no brackets>
aws_secret_access_key = <insert secret key, no brackets>

While using Amazon’s service, you must also specify the AWS region in the ~/.aws/config file, for example:

[default]
region = us-east-1

Additional profiles can be added to these files by appending the relevant information in additional blocks:

[default]
aws_access_key_id = <insert key, no brackets>
aws_secret_access_key = <insert secret key, no brackets>

[profilename2]
aws_access_key_id = <insert key, no brackets>
aws_secret_access_key = <insert secret key, no brackets>

Place these two files in a folder named .aws under the home directory for the user running your Dataverse Installation on Payara. (From the AWS Command Line Interface Documentation: “In order to separate credentials from less sensitive options, region and output format are stored in a separate file named config in the same folder”)

Console Commands to Set Up Access Configuration

Begin by installing the CLI tool pip to install the AWS command line interface if you don’t have it.

First, we’ll get our access keys set up. If you already have your access keys configured, skip this step. From the command line, run:

  • pip install awscli

  • aws configure

You’ll be prompted to enter your Access Key ID and secret key, which should be issued to your AWS account. The subsequent config steps after the access keys are up to you. For reference, the keys will be stored in ~/.aws/credentials, and your AWS access region in ~/.aws/config.

TIP: When using a custom S3 URL endpoint, you need to add it to every aws call: aws --endpoint-url <URL> s3 ...

(you may omit it while configuring).

Second: Configure Your Dataverse Installation to use S3 Storage

To set up an S3 store, you must define the id, type, and label as for any store:

./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.<id>.type=s3"
./asadmin $ASADMIN_OPTS create-jvm-options "\-Ddataverse.files.<id>.label=<label>"

Then, we’ll need to identify which S3 bucket we’re using. Replace <your_bucket_name> with, of course, your bucket:

./asadmin create-jvm-options "-Ddataverse.files.<id>.bucket-name=<your_bucket_name>"

Optionally, you can have users download files from S3 directly rather than having files pass from S3 through Payara to your users. To accomplish this, set dataverse.files.<id>.download-redirect to true like this:

./asadmin create-jvm-options "-Ddataverse.files.<id>.download-redirect=true"

If you enable dataverse.files.<id>.download-redirect as described above, note that the S3 URLs expire after an hour by default but you can configure the expiration time using the dataverse.files.<id>.url-expiration-minutes JVM option. Here’s an example of setting the expiration time to 120 minutes:

./asadmin create-jvm-options "-Ddataverse.files.<id>.url-expiration-minutes=120"

By default, your store will use the [default] profile in you .aws configuration files. To use a different profile, which would be necessary if you have two s3 stores at different locations, you can specify the profile to use:

./asadmin create-jvm-options "-Ddataverse.files.<id>.profile=<profilename>"

Larger installations may want to increase the number of open S3 connections allowed (default is 256): For example,

./asadmin create-jvm-options "-Ddataverse.files.<id>.connection-pool-size=4096"

In case you would like to configure Dataverse to use a custom S3 service instead of Amazon S3 services, please add the options for the custom URL and region as documented below. Please read above if your desired combination has been tested already and what other options have been set for a successful integration.

Lastly, go ahead and restart your Payara server. With Dataverse deployed and the site online, you should be able to upload datasets and data files and see the corresponding files in your S3 bucket. Within a bucket, the folder structure emulates that found in local file storage.

<?>

Provide static access key ID. Read before use!

""

dataverse.files.<id>.secret-key

<?>

Provide static secret access key. Read before use!

""
Credentials via MicroProfile Config

Optionally, you may provide static credentials for each S3 storage using MicroProfile Config options:

  • dataverse.files.<id>.access-key for this storages “access key ID”

  • dataverse.files.<id>.secret-key for this storages “secret access key”

You may provide the values for these via any of the supported config sources.

WARNING:

For security, do not use the sources “environment variable” or “system property” (JVM option) in a production context! Rely on password alias, secrets directory or cloud based sources instead!

NOTE:

  1. Providing both AWS CLI profile files (as setup in first step) and static keys, credentials from ~/.aws will win over configured keys when valid!

  2. A non-empty dataverse.files.<id>.profile will be ignored when no credentials can be found for this profile name. Current codebase does not make use of “named profiles” as seen for AWS CLI besides credentials.

Reported Working S3-Compatible Storage
Minio v2018-09-12

Set dataverse.files.<id>.path-style-access=true, as Minio works path-based. Works pretty smooth, easy to setup. Can be used for quick testing, too: just use the example values above. Uses the public (read: unsecure and possibly slow) https://play.minio.io:9000 service.

StorJ Object Store

StorJ is a distributed object store that can be configured with an S3 gateway. Per the S3 Storage instructions above, you’ll first set up the StorJ S3 store by defining the id, type, and label. After following the general installation, set the following configurations to use a StorJ object store: dataverse.files.<id>.payload-signing=true and dataverse.files.<id>.chunked-encoding=false.

Note that for direct uploads and downloads, Dataverse redirects to the proxy-url but presigns the urls based on the dataverse.files.<id>.custom-endpoint-url. Also, note that if you choose to enable dataverse.files.<id>.download-redirect the S3 URLs expire after 60 minutes by default. You can change that minute value to reflect a timeout value that’s more appropriate by using dataverse.files.<id>.url-expiration-minutes.

Surf Object Store v2019-10-30

Set dataverse.files.<id>.payload-signing=true and dataverse.files.<id>.chunked-encoding=false to use Surf Object Store.

Note that the dataverse.files.<id>.proxy-url setting can be used in installations where the object store is proxied, but it should be considered an advanced option that will require significant expertise to properly configure. For direct uploads and downloads, Dataverse redirects to the proxy-url but presigns the urls based on the dataverse.files.<id>.custom-endpoint-url. Additional configuration (appropriate CORS settings, proxy caching/timeout configuration, and proxy settings to pass headers to/from S3 and to avoid adding additional headers) will also be needed to enable use of a proxy with direct upload and download. For Amazon AWS, see comments in the edu.harvard.iq.dataverse.dataaccess.S3AccessIO class about support for AWS’s bucket-specific DNS names.

HINT: If you are successfully using an S3 storage implementation not yet listed above, please feel free to open an issue at Github and describe your setup. We will be glad to add it here.

Migrating from Local Storage to S3

Is currently documented on the Deployment page.

Branding Your Installation

The name of your root Dataverse collection is the brand of your Dataverse installation and appears in various places such as notifications and support links, as outlined in the :SystemEmail section below. To further brand your installation and make it your own, the Dataverse Software provides configurable options for easy-to-add (and maintain) custom branding for your Dataverse installation. Here are the custom branding and content options you can add:

  • Custom welcome/homepage

  • Logo image to navbar

  • Header

  • Footer

  • CSS stylesheet

Downloadable sample HTML and CSS files are provided below which you can edit as you see fit. It’s up to you to create a directory in which to store these files, such as /var/www/dataverse in the examples below.

You may also want to look at samples at https://github.com/shlake/LibraDataHomepage from community member Sherry Lake as well as her poster from the Dataverse Project Community Meeting 2018 called “Branding Your Local Dataverse Installation”: https://github.com/IQSS/dataverse/files/2128735/UVaHomePage.pdf

A simpler option to brand and customize your installation is to utilize the Dataverse collection theme, which each Dataverse collection has, that allows you to change colors, add a logo, tagline or website link to the Dataverse collection header section of the page. Those options are outlined in the Dataverse Collection Management section of the User Guide.

Custom Homepage

The Dataverse Software allows you to use a custom homepage or welcome page in place of the default root Dataverse collection page. This allows for complete control over the look and feel of your installation’s homepage.

Download this sample: custom-homepage.html and place it at /var/www/dataverse/branding/custom-homepage.html.

Once you have the location of your custom homepage HTML file, run this curl command to add it to your settings:

curl -X PUT -d '/var/www/dataverse/branding/custom-homepage.html' http://localhost:8080/api/admin/settings/:HomePageCustomizationFile

If you prefer to start with less of a blank slate, you can review the custom homepage used by the Harvard Dataverse Repository, which includes branding messaging, action buttons, search input, subject links, and recent dataset links. This page was built to utilize the Metrics API to deliver dynamic content to the page via Javascript. The files can be found at https://github.com/IQSS/dataverse.harvard.edu

Note that the custom-homepage.html file provided has multiple elements that assume your root Dataverse collection still has an alias of “root”. While you were branding your root Dataverse collection, you may have changed the alias to “harvard” or “librascholar” or whatever and you should adjust the custom homepage code as needed.

For more background on what this curl command above is doing, see the Database Settings section below. If you decide you’d like to remove this setting, use the following curl command:

curl -X DELETE http://localhost:8080/api/admin/settings/:HomePageCustomizationFile

Custom Header

Download this sample: custom-header.html and place it at /var/www/dataverse/branding/custom-header.html.

Once you have the location of your custom header HTML file, run this curl command to add it to your settings:

curl -X PUT -d '/var/www/dataverse/branding/custom-header.html' http://localhost:8080/api/admin/settings/:HeaderCustomizationFile

If you have enabled a custom header or navbar logo, you might prefer to disable the theme of the root dataverse. You can do so by setting :DisableRootDataverseTheme to true like this:

curl -X PUT -d 'true' http://localhost:8080/api/admin/settings/:DisableRootDataverseTheme

Please note: Disabling the display of the root Dataverse collection theme also disables your ability to edit it. Remember that Dataverse collection owners can set their Dataverse collections to “inherit theme” from the root. Those Dataverse collections will continue to inherit the root Dataverse collection theme (even though it no longer displays on the root). If you would like to edit the root Dataverse collection theme in the future, you will have to re-enable it first.

Custom Stylesheet

You can style your custom homepage, footer and header content with a custom CSS file. With advanced CSS know-how, you can achieve custom branding and page layouts by utilizing position, padding or margin properties.

Download this sample: custom-stylesheet.css and place it at /var/www/dataverse/branding/custom-stylesheet.css.

Once you have the location of your custom CSS file, run this curl command to add it to your settings:

curl -X PUT -d '/var/www/dataverse/branding/custom-stylesheet.css' http://localhost:8080/api/admin/settings/:StyleCustomizationFile

Internationalization

The Dataverse Software is being translated into multiple languages by the Dataverse Project Community! Please see below for how to help with this effort!

Adding Multiple Languages to the Dropdown in the Header

The presence of the :Languages database setting adds a dropdown in the header for multiple languages. For example to add English and French to the dropdown:

curl http://localhost:8080/api/admin/settings/:Languages -X PUT -d '[{"locale":"en","title":"English"},{"locale":"fr","title":"Français"}]'

When a user selects one of the available choices, the Dataverse user interfaces will be translated into that language (assuming you also configure the “lang” directory and populate it with translations as described below).

Allowing the Language Used for Dataset Metadata to be Specified

Since dataset metadata can only be entered in one language, and administrators may wish to limit which languages metadata can be entered in, Dataverse also offers a separate setting defining allowed metadata languages. The presence of the :MetadataLanguages database setting identifies the available options (which can be different from those in the :Languages setting above, with fewer or more options).

Dataverse collection admins can select from these options to indicate which language should be used for new Datasets created with that specific collection. If they do not, users will be asked when creating a dataset to select the language they want to use when entering metadata.

When creating or editing a dataset, users will be asked to enter the metadata in that language. The metadata language selected will also be shown when dataset metadata is viewed and will be included in metadata exports (as appropriate for each format) for published datasets:

curl http://localhost:8080/api/admin/settings/:MetadataLanguages -X PUT -d '[{"locale":"en","title":"English"},{"locale":"fr","title":"Français"}]'

Note that metadata selected from Controlled Vocabularies will also display in the metadata language of the dataset, but only if translations have been configured, i.e. you configure the “lang” directory and populate it with translations as described below). In metadata export files, controlled vocabulary values will be included in the Dataverse installations default language and in the metadata language of the dataset (if specified).

Configuring the “lang” Directory

Translations for the Dataverse Software are stored in “properties” files in a directory on disk (e.g. /home/dataverse/langBundles) that you specify with the dataverse.lang.directory dataverse.lang.directory JVM option, like this:

./asadmin create-jvm-options '-Ddataverse.lang.directory=/home/dataverse/langBundles'

Go ahead and create the directory you specified.

mkdir /home/dataverse/langBundles

Creating a languages.zip File

The Dataverse Software provides and API endpoint for adding languages using a zip file.

First, clone the “dataverse-language-packs” git repo.

git clone https://github.com/GlobalDataverseCommunityConsortium/dataverse-language-packs.git

Take a look at https://github.com/GlobalDataverseCommunityConsortium/dataverse-language-packs/branches to see if the version of the Dataverse Software you’re running has translations.

Change to the directory for the git repo you just cloned.

cd dataverse-language-packs

Switch (git checkout) to the branch based on the Dataverse Software version you are running. The branch “dataverse-v4.13” is used in the example below.

export BRANCH_NAME=dataverse-v4.13

git checkout $BRANCH_NAME

Create a “languages” directory in “/tmp”.

mkdir /tmp/languages

Copy the properties files into the “languages” directory

cp -R en_US/*.properties /tmp/languages

cp -R fr_CA/*.properties /tmp/languages

Create the zip file

cd /tmp/languages

zip languages.zip *.properties

Load the languages.zip file into your Dataverse Installation

Now that you have a “languages.zip” file, you can load it into your Dataverse installation with the command below.

curl http://localhost:8080/api/admin/datasetfield/loadpropertyfiles -X POST --upload-file /tmp/languages/languages.zip -H "Content-Type: application/zip"

Click on the languages using the drop down in the header to try them out.

How to Help Translate the Dataverse Software Into Your Language

Please join the dataverse-internationalization-wg mailing list and contribute to https://github.com/GlobalDataverseCommunityConsortium/dataverse-language-packs to help translate the Dataverse Software into various languages!

Some external tools are also ready to be translated, especially if they are using the {localeCode} reserved word in their tool manifest. For details, see the Building External Tools section of the API Guide.

Web Analytics Code

Your analytics code can be added to your Dataverse installation in a similar fashion to how you brand it, by adding a custom HTML file containing the analytics code snippet and adding the file location to your settings.

Popular analytics providers Google Analytics (https://www.google.com/analytics/) and Matomo (formerly “Piwik”; https://matomo.org/) have been set up to work with the Dataverse Software. Use the documentation they provide to add the analytics code to your custom HTML file. This allows for more control of your analytics, making it easier to customize what you prefer to track.

Create your own analytics-code.html file using the analytics code snippet provided by Google or Matomo and place it somewhere on the server, outside the application deployment directory; for example: /var/www/dataverse/branding/analytics-code.html. Here is an example of what your HTML file will look like:

<!-- Global Site Tag (gtag.js) - Google Analytics -->
<script async="async" src="https://www.googletagmanager.com/gtag/js?id=YOUR-ACCOUNT-CODE"></script>
<script>
    //<![CDATA[
    window.dataLayer = window.dataLayer || [];
    function gtag(){dataLayer.push(arguments);}
    gtag('js', new Date());

    gtag('config', 'YOUR-ACCOUNT-CODE');
    //]]>
</script>

IMPORTANT: Note the “async” attribute in the first script line above. In the documentation provided by Google, its value is left blank (as in <script async src="...">). It must be set as in the example above (<script async="async" src="...">), otherwise it may cause problems with some browsers.

Once you have created the analytics file, run this curl command to add it to your settings (using the same file location as in the example above):

curl -X PUT -d '/var/www/dataverse/branding/analytics-code.html' http://localhost:8080/api/admin/settings/:WebAnalyticsCode

Tracking Button Clicks

The basic analytics configuration above tracks page navigation. However, it does not capture potentially interesting events, such as those from users clicking buttons on pages, that do not result in a new page opening. In a Dataverse installation, these events include file downloads, requesting access to restricted data, exporting metadata, social media sharing, requesting citation text, launching external tools, contacting authors, and launching computations.

Both Google and Matomo provide the optional capability to track such events and the Dataverse Software has added CSS style classes (btn-compute, btn-contact, btn-download, btn-explore, btn-export, btn-preview, btn-request, btn-share, and downloadCitation) to it’s HTML to facilitate it.

For Google Analytics, the example script at analytics-code.html will track both page hits and events within your Dataverse installation. You would use this file in the same way as the shorter example above, putting it somewhere outside your deployment directory, replacing YOUR ACCOUNT CODE with your actual code and setting :WebAnalyticsCode to reference it.

Once this script is running, you can look in the Google Analytics console (Realtime/Events or Behavior/Events) and view events by type and/or the Dataset or File the event involves.

Configuring Licenses

Out of the box, users select from the following licenses or terms:

  • CC0 1.0 (default)

  • CC BY 4.0

  • Custom Dataset Terms

You have a lot of control over which licenses and terms are available. You can remove licenses and add new ones. You can decide which license is the default. You can remove “Custom Dataset Terms” as a option. You can remove all licenses and make “Custom Dataset Terms” the only option.

Before making changes, you are encouraged to read the Terms section of the User Guide about why CC0 is the default and what the “Custom Dataset Terms” option allows.

Setting the Default License

The default license can be set with a curl command as explained in the API Guide under Manage Available Standard License Terms.

Note that “Custom Dataset Terms” is not a license and cannot be set to be the default.

Adding Licenses

Licenses are added with curl using JSON file as explained in the API Guide under Manage Available Standard License Terms.

Adding Custom Licenses

If you are interested in adding a custom license, you will need to create your own JSON file as explained in see Standardizing Custom Licenses.

Removing Licenses

Licenses can be removed with a curl command as explained in the API Guide under Manage Available Standard License Terms.

Disabling Custom Dataset Terms

See :AllowCustomTermsOfUse for how to disable the “Custom Dataset Terms” option.

BagIt Export

Your Dataverse installation may be configured to submit a copy of published Datasets, packaged as Research Data Alliance conformant zipped BagIt bags to Chronopolis via DuraCloud or alternately to any folder on the local filesystem.

The Dataverse Software offers an internal archive workflow which may be configured as a PostPublication workflow via an admin API call to manually submit previously published Datasets and prior versions to a configured archive such as Chronopolis. The workflow creates a JSON-LD serialized OAI-ORE map file, which is also available as a metadata export format in the Dataverse Software web interface.

At present, the DPNSubmitToArchiveCommand, LocalSubmitToArchiveCommand, and GoogleCloudSubmitToArchive are the only implementations extending the AbstractSubmitToArchiveCommand and using the configurable mechanisms discussed below.

Duracloud Configuration

Also note that while the current Chronopolis implementation generates the bag and submits it to the archive’s DuraCloud interface, the step to make a ‘snapshot’ of the space containing the Bag (and verify it’s successful submission) are actions a curator must take in the DuraCloud interface.

The minimal configuration to support an archiver integration involves adding a minimum of two Dataverse Software Keys and any required Payara jvm options. The example instructions here are specific to the DuraCloud Archiver:

:ArchiverClassName - the fully qualified class to be used for archiving. For example:

curl http://localhost:8080/api/admin/settings/:ArchiverClassName -X PUT -d "edu.harvard.iq.dataverse.engine.command.impl.DuraCloudSubmitToArchiveCommand"

:ArchiverSettings - the archiver class can access required settings including existing Dataverse installation settings and dynamically defined ones specific to the class. This setting is a comma-separated list of those settings. For example:

curl http://localhost:8080/api/admin/settings/:ArchiverSettings -X PUT -d ":DuraCloudHost, :DuraCloudPort, :DuraCloudContext"

The DPN archiver defines three custom settings, one of which is required (the others have defaults):

:DuraCloudHost - the URL for your organization’s Duracloud site. For example:

curl http://localhost:8080/api/admin/settings/:DuraCloudHost -X PUT -d "qdr.duracloud.org"

:DuraCloudPort and :DuraCloudContext are also defined if you are not using the defaults (“443” and “duracloud” respectively). (Note: these settings are only in effect if they are listed in the :ArchiverSettings. Otherwise, they will not be passed to the DuraCloud Archiver class.)

Archivers may require JVM options as well. For the Chronopolis archiver, the username and password associated with your organization’s Chronopolis/DuraCloud account should be configured in Payara:

./asadmin create-jvm-options '-Dduracloud.username=YOUR_USERNAME_HERE'

./asadmin create-jvm-options '-Dduracloud.password=YOUR_PASSWORD_HERE'

Local Path Configuration

ArchiverClassName - the fully qualified class to be used for archiving. For example:

curl -X PUT -d "edu.harvard.iq.dataverse.engine.command.impl.LocalSubmitToArchiveCommand" http://localhost:8080/api/admin/settings/:ArchiverClassName

:BagItLocalPath - the path to where you want to store BagIt. For example:

curl -X PUT -d /home/path/to/storage http://localhost:8080/api/admin/settings/:BagItLocalPath

:ArchiverSettings - the archiver class can access required settings including existing Dataverse installation settings and dynamically defined ones specific to the class. This setting is a comma-separated list of those settings. For example:

curl http://localhost:8080/api/admin/settings/:ArchiverSettings -X PUT -d ":BagItLocalPath"

:BagItLocalPath is the file path that you’ve set in :ArchiverSettings.

Google Cloud Configuration

The Google Cloud Archiver can send Dataverse Project Bags to a bucket in Google’s cloud, including those in the ‘Coldline’ storage class (cheaper, with slower access)

curl http://localhost:8080/api/admin/settings/:ArchiverClassName -X PUT -d "edu.harvard.iq.dataverse.engine.command.impl.GoogleCloudSubmitToArchiveCommand"

curl http://localhost:8080/api/admin/settings/:ArchiverSettings -X PUT -d ":GoogleCloudBucket, :GoogleCloudProject"

The Google Cloud Archiver defines two custom settings, both are required. The credentials for your account, in the form of a json key file, must also be obtained and stored locally (see below):

In order to use the Google Cloud Archiver, you must have a Google account. You will need to create a project and bucket within that account and provide those values in the settings:

:GoogleCloudBucket - the name of the bucket to use. For example:

curl http://localhost:8080/api/admin/settings/:GoogleCloudBucket -X PUT -d "qdr-archive"

:GoogleCloudProject - the name of the project managing the bucket. For example:

curl http://localhost:8080/api/admin/settings/:GoogleCloudProject -X PUT -d "qdr-project"

The Google Cloud Archiver also requires a key file that must be renamed to ‘googlecloudkey.json’ and placed in the directory identified by your ‘dataverse.files.directory’ jvm option. This file can be created in the Google Cloud Console. (One method: Navigate to your Project ‘Settings’/’Service Accounts’, create an account, give this account the ‘Cloud Storage’/’Storage Admin’ role, and once it’s created, use the ‘Actions’ menu to ‘Create Key’, selecting the ‘JSON’ format option. Use this as the ‘googlecloudkey.json’ file.)

For example:

cp <your key file> /usr/local/payara5/glassfish/domains/domain1/files/googlecloudkey.json

API Call

Once this configuration is complete, you, as a user with the PublishDataset permission, should be able to use the API call to manually submit a DatasetVersion for processing:

curl -H "X-Dataverse-key: <key>" http://localhost:8080/api/admin/submitDataVersionToArchive/{id}/{version}

where:

{id} is the DatasetId (or :persistentId with the ?persistentId="<DOI>" parameter), and

{version} is the friendly version number, e.g. “1.2”.

The submitDataVersionToArchive API (and the workflow discussed below) attempt to archive the dataset version via an archive specific method. For Chronopolis, a DuraCloud space named for the dataset (it’s DOI with ‘:’ and ‘.’ replaced with ‘-‘) is created and two files are uploaded to it: a version-specific datacite.xml metadata file and a BagIt bag containing the data and an OAI-ORE map file. (The datacite.xml file, stored outside the Bag as well as inside is intended to aid in discovery while the ORE map file is ‘complete’, containing all user-entered metadata and is intended as an archival record.)

In the Chronopolis case, since the transfer from the DuraCloud front-end to archival storage in Chronopolis can take significant time, it is currently up to the admin/curator to submit a ‘snap-shot’ of the space within DuraCloud and to monitor its successful transfer. Once transfer is complete the space should be deleted, at which point the Dataverse Software API call can be used to submit a Bag for other versions of the same Dataset. (The space is reused, so that archival copies of different Dataset versions correspond to different snapshots of the same DuraCloud space.).

PostPublication Workflow

To automate the submission of archival copies to an archive as part of publication, one can setup a Dataverse Software Workflow using the “archiver” workflow step - see the Workflows guide.

The archiver step uses the configuration information discussed above including the :ArchiverClassName setting. The workflow step definition should include the set of properties defined in :ArchiverSettings in the workflow definition.

To active this workflow, one must first install a workflow using the archiver step. A simple workflow that invokes the archiver step configured to submit to DuraCloud as its only action is included in the Dataverse Software at /scripts/api/data/workflows/internal-archiver-workflow.json.

Using the Workflow Native API (see the Native API guide) this workflow can be installed using:

curl -X POST -H 'Content-type: application/json' --upload-file internal-archiver-workflow.json http://localhost:8080/api/admin/workflows

The workflow id returned in this call (or available by doing a GET of /api/admin/workflows ) can then be submitted as the default PostPublication workflow:

curl -X PUT -d {id} http://localhost:8080/api/admin/workflows/default/PostPublishDataset

Once these steps are taken, new publication requests will automatically trigger submission of an archival copy to the specified archiver, Chronopolis’ DuraCloud component in this example. For Chronopolis, as when using the API, it is currently the admin’s responsibility to snap-shot the DuraCloud space and monitor the result. Failure of the workflow, (e.g. if DuraCloud is unavailable, the configuration is wrong, or the space for this dataset already exists due to a prior publication action or use of the API), will create a failure message but will not affect publication itself.

Going Live: Launching Your Production Deployment

This guide has attempted to take you from kicking the tires on the Dataverse Software to finalizing your installation before letting real users in. In theory, all this work could be done on a single server but better would be to have separate staging and production environments so that you can deploy upgrades to staging before deploying to production. This “Going Live” section is about launching your production environment.

Before going live with your Dataverse installation, you must take the steps above under “Securing Your Installation” and you should at least review the various configuration options listed below. An attempt has been made to put the more commonly-configured options earlier in the list.

Out of the box, the Dataverse Software attempts to block search engines from crawling your Dataverse installation so that test datasets do not appear in search results until you’re ready.

Letting Search Engines Crawl Your Installation

Ensure robots.txt Is Not Blocking Search Engines

For a public production Dataverse installation, it is probably desired that search agents be able to index published pages (AKA - pages that are visible to an unauthenticated user). Polite crawlers usually respect the Robots Exclusion Standard; we have provided an example of a production robots.txt here).

We strongly recommend using the crawler rules in the sample robots.txt linked above. Note that they make the Dataverse collection and dataset pages accessible to the search engine bots; but discourage them from actually crawling the site, by following any search links - facets and such - on the Dataverse collection pages. Such crawling is very inefficient in terms of system resources, and often results in confusing search results for the end users of the search engines (for example, when partial search results are indexed as individual pages).

The recommended solution instead is to directly point the bots to the dataset and Dataverse collection pages that need to be indexed, by advertising them via an explicit sitemap (please see the next section for details on how to generate the sitemap).

You can of course modify your own robots.txt to suit your specific needs as necessary. If you don’t want your datasets to be indexed at all, you can tell the bots to stay away from your site completely. But, as noted above, keep in mind that only the good, “polite” bots honor these rules! You are not really blocking anyone from accessing your site by adding a “Disallow” rule in robots.txt - it is a suggestion only. A rogue bot can and will violate it. If you are having trouble with the site being overloaded with what looks like heavy automated crawling, you may have to resort to blocking this traffic by other means - for example, via rewrite rules in Apache, or even by a Firewall.

(See the sample robots.txt file linked above for some comments on how to set up different “Allow” and “Disallow” rules for different crawler bots)

You have a couple of options for putting an updated robots.txt file into production. If you are fronting Payara with Apache as recommended above, you can place robots.txt in the root of the directory specified in your VirtualHost and to your Apache config a ProxyPassMatch line like the one below to prevent Payara from serving the version of robots.txt that is embedded in the Dataverse Software war file:

# don't let Payara serve its version of robots.txt
ProxyPassMatch ^/robots.txt$ !

For more of an explanation of ProxyPassMatch see the Shibboleth section.

If you are not fronting Payara with Apache you’ll need to prevent Payara from serving the robots.txt file embedded in the war file by overwriting robots.txt after the war file has been deployed. The downside of this technique is that you will have to remember to overwrite robots.txt in the “exploded” war file each time you deploy the war file, which probably means each time you upgrade to a new version of the Dataverse Software. Furthermore, since the version of the Dataverse Software is always incrementing and the version can be part of the file path, you will need to be conscious of where on disk you need to replace the file. For example, for Dataverse Software 4.6.1 the path to robots.txt may be /usr/local/payara5/glassfish/domains/domain1/applications/dataverse-4.6.1/robots.txt with the version number 4.6.1 as part of the path.

Creating a Sitemap and Submitting it to Search Engines

Search engines have an easier time indexing content when you provide them a sitemap. The Dataverse Software sitemap includes URLs to all published Dataverse collections and all published datasets that are not harvested or deaccessioned.

Create or update your sitemap by adding the following curl command to cron to run nightly or as you see fit:

curl -X POST http://localhost:8080/api/admin/sitemap

This will create or update a file in the following location unless you have customized your installation directory for Payara:

/usr/local/payara5/glassfish/domains/domain1/docroot/sitemap/sitemap.xml

On Dataverse installation with many datasets, the creation or updating of the sitemap can take a while. You can check Payara’s server.log file for “BEGIN updateSiteMap” and “END updateSiteMap” lines to know when the process started and stopped and any errors in between.

https://demo.dataverse.org/sitemap.xml is the sitemap URL for the Dataverse Project Demo site and yours should be similar.

Once the sitemap has been generated and placed in the domain docroot directory, it will become available to the outside callers at <YOUR_SITE_URL>/sitemap/sitemap.xml; it will also be accessible at <YOUR_SITE_URL>/sitemap.xml (via a pretty-faces rewrite rule). Some search engines will be able to find it at this default location. Some, including Google, need to be specifically instructed to retrieve it.

One way to submit your sitemap URL to Google is by using their “Search Console” (https://search.google.com/search-console). In order to use the console, you will need to authenticate yourself as the owner of your Dataverse site. Various authentication methods are provided; but if you are already using Google Analytics, the easiest way is to use that account. Make sure you are logged in on Google with the account that has the edit permission on your Google Analytics property; go to the search console and enter the root URL of your Dataverse installation, then choose Google Analytics as the authentication method. Once logged in, click on “Sitemaps” in the menu on the left. (todo: add a screenshot?) Consult Google’s “submit a sitemap” instructions for more information; and/or similar instructions for other search engines.

Putting Your Dataverse Installation on the Map at dataverse.org

Congratulations! You’ve gone live! It’s time to announce your new data repository to the world! You are also welcome to contact support@dataverse.org to have the Dataverse Project Team add your installation to the map at http://dataverse.org . Thank you for installing the Dataverse Software!

Administration of Your Dataverse Installation

Now that you’re live you’ll want to review the Admin Guide for more information about the ongoing administration of a Dataverse installation.

Setting Up Integrations

Before going live, you might want to consider setting up integrations to make it easier for your users to deposit or explore data. See the Integrations section of the Admin Guide for details.

JVM Options

JVM stands for Java Virtual Machine and as a Java application, Payara can read JVM options when it is started. A number of JVM options are configured by the installer below is a complete list of the Dataverse Software-specific JVM options. You can inspect the configured options by running:

./asadmin list-jvm-options | egrep 'dataverse|doi'

When changing values these values with asadmin, you’ll need to delete the old value before adding a new one, like this:

./asadmin delete-jvm-options "-Ddataverse.fqdn=old.example.com"

./asadmin create-jvm-options "-Ddataverse.fqdn=dataverse.example.com"

It’s also possible to change these values by stopping Payara, editing payara5/glassfish/domains/domain1/config/domain.xml, and restarting Payara.

dataverse.fqdn

If the Dataverse installation has multiple DNS names, this option specifies the one to be used as the “official” host name. For example, you may want to have dataverse.example.edu, and not the less appealing server-123.socsci.example.edu to appear exclusively in all the registered global identifiers, Data Deposit API records, etc.

The password reset feature requires dataverse.fqdn to be configured.

Note

Do note that whenever the system needs to form a service URL, by default, it will be formed with https:// and port 443. I.e., https://{dataverse.fqdn}/ If that does not suit your setup, you can define an additional option, dataverse.siteUrl, explained below.

dataverse.siteUrl

Note

and specify the protocol and port number you would prefer to be used to advertise the URL for your Dataverse installation. For example, configured in domain.xml: <jvm-options>-Ddataverse.fqdn=dataverse.example.edu</jvm-options> <jvm-options>-Ddataverse.siteUrl=http://${dataverse.fqdn}:8080</jvm-options>

dataverse.files.directory

This is how you configure the path Dataverse uses for temporary files. (File store specific dataverse.files.<id>.directory options set the permanent data storage locations.)

dataverse.auth.password-reset-timeout-in-minutes

Users have 60 minutes to change their passwords by default. You can adjust this value here.

dataverse.db.name

The PostgreSQL database name to use for the Dataverse installation.

Defaults to dataverse (but the installer sets it to dvndb).

Can also be set via MicroProfile Config API sources, e.g. the environment variable DATAVERSE_DB_NAME.

dataverse.db.user

The PostgreSQL user name to connect with.

Defaults to dataverse (but the installer sets it to dvnapp).

Can also be set via MicroProfile Config API sources, e.g. the environment variable DATAVERSE_DB_USER.

dataverse.db.password

The PostgreSQL users password to connect with.

Preferrably use a JVM alias, as passwords in environment variables aren’t safe.

echo "AS_ADMIN_ALIASPASSWORD=change-me-super-secret" > /tmp/password.txt
asadmin create-password-alias --passwordfile /tmp/password.txt dataverse.db.password
rm /tmp/password.txt

Can also be set via MicroProfile Config API sources, e.g. the environment variable DATAVERSE_DB_PASSWORD.

dataverse.db.host

The PostgreSQL server to connect to.

Defaults to localhost.

Can also be set via MicroProfile Config API sources, e.g. the environment variable DATAVERSE_DB_HOST.

dataverse.db.port

The PostgreSQL server port to connect to.

Defaults to 5432, the default PostgreSQL port.

Can also be set via MicroProfile Config API sources, e.g. the environment variable DATAVERSE_DB_PORT.

dataverse.rserve.host

Host name for Rserve, used for tasks that require use of R (to ingest RData files and to save tabular data as RData frames).

dataverse.rserve.port

Port number for Rserve, used for tasks that require use of R (to ingest RData files and to save tabular data as RData frames).

dataverse.rserve.user

Username for Rserve, used for tasks that require use of R (to ingest RData files and to save tabular data as RData frames).

dataverse.rserve.password

Password for Rserve, used for tasks that require use of R (to ingest RData files and to save tabular data as RData frames).

dataverse.rserve.tempdir

Temporary directory used by Rserve (defaults to /tmp/Rserv). Note that this location is local to the host on which Rserv is running (specified in dataverse.rserve.host above). When talking to Rserve, Dataverse needs to know this location in order to generate absolute path names of the files on the other end.

dataverse.dropbox.key

Dropbox provides a Chooser app, which is a Javascript component that allows you to upload files to your Dataverse installation from Dropbox. It is an optional configuration setting, which requires you to pass it an app key and configure the :UploadMethods database setting. For more information on setting up your Chooser app, visit https://www.dropbox.com/developers/chooser.

./asadmin create-jvm-options "-Ddataverse.dropbox.key={{YOUR_APP_KEY}}"

dataverse.path.imagemagick.convert

For overriding the default path to the convert binary from ImageMagick (/usr/bin/convert).

dataverse.dataAccess.thumbnail.image.limit

For limiting the size (in bytes) of thumbnail images generated from files. The default is 3000000 bytes (3 MB).

dataverse.dataAccess.thumbnail.pdf.limit

For limiting the size (in bytes) of thumbnail images generated from files. The default is 1000000 bytes (1 MB).

doi.baseurlstring

As of this writing, “https://mds.datacite.org” (DataCite) and “https://ezid.cdlib.org” (EZID) are the main valid values.

While the above two options are recommended because they have been tested by the Dataverse Project Team, it is also possible to use a DataCite Client API as a proxy to DataCite. In this case, requests made to the Client API are captured and passed on to DataCite for processing. The application will interact with the DataCite Client API exactly as if it were interacting directly with the DataCite API, with the only difference being the change to the base endpoint URL.

For example, the Australian Data Archive (ADA) successfully uses the Australian National Data Service (ANDS) API (a proxy for DataCite) to mint their DOIs through their Dataverse installation using a doi.baseurlstring value of “https://researchdata.ands.org.au/api/doi/datacite” as documented at https://documentation.ands.org.au/display/DOC/ANDS+DataCite+Client+API . As ADA did for ANDS DOI minting, any DOI provider (and their corresponding DOI configuration parameters) other than DataCite must be tested with the Dataverse Software to establish whether or not it will function properly.

Out of the box, the Dataverse Software is configured to use a test MDS DataCite base URL string. You can delete it like this:

./asadmin delete-jvm-options '-Ddoi.baseurlstring=https\://mds.test.datacite.org'

Then, to switch to production DataCite, you can issue the following command:

./asadmin create-jvm-options '-Ddoi.baseurlstring=https\://mds.datacite.org'

See also these related database settings below:

doi.dataciterestapiurlstring

This configuration option affects the updateCitationsForDataset API endpoint documented under Configuring Your Dataverse Installation for Make Data Count Citations in the Admin Guide as well as the /pids/* API.

As of this writing, “https://api.datacite.org” (DataCite) and “https://api.test.datacite.org” (DataCite Testing) are the main valid values.

Out of the box, the Dataverse Software is configured to use a test DataCite REST API base URL string. You can delete it like this:

./asadmin delete-jvm-options '-Ddoi.dataciterestapiurlstring=https\://api.test.datacite.org'

Then, to switch to production DataCite, you can issue the following command:

./asadmin create-jvm-options '-Ddoi.dataciterestapiurlstring=https\://api.datacite.org'

For backward compatibility, if this option is not defined, the value of ‘-Ddoi.mdcbaseurlstring’ is used if set. If not the default used is “https://api.datacite.org:.

See also these related database settings below:

doi.username

Used in conjuction with doi.baseurlstring.

Once you have a username from your provider, you can enter it like this:

./asadmin create-jvm-options '-Ddoi.username=YOUR_USERNAME_HERE'

doi.password

Used in conjuction with doi.baseurlstring.

Once you have a password from your provider, you can enter it like this:

./asadmin create-jvm-options '-Ddoi.password=YOUR_PASSWORD_HERE'

dataverse.handlenet.admcredfile

If you’re using handles, this JVM setting configures access credentials so your Dataverse installation can talk to your Handle.Net server. This is the private key generated during Handle.Net server installation. Typically the full path is set to handle/svr_1/admpriv.bin. Please refer to Handle.Net’s documentation for more info.

dataverse.handlenet.admprivphrase

This JVM setting is also part of handles configuration. The Handle.Net installer lets you choose whether to encrypt the admcredfile private key or not. If you do encrypt it, this is the pass phrase that it’s encrypted with.

dataverse.handlenet.index

If you want to use different index than the default 300

dataverse.timerServer

This JVM option is only relevant if you plan to run multiple Payara servers for redundancy. Only one Payara server can act as the dedicated timer server and for details on promoting or demoting a Payara server to handle this responsibility, see Dataverse Installation Application Timers.

dataverse.lang.directory

This JVM option is used to configure the path where all the language specific property files are to be stored. If this option is set then the English property file must be present in the path along with any other language property file. You can download language property files from https://github.com/GlobalDataverseCommunityConsortium/dataverse-language-packs

./asadmin create-jvm-options '-Ddataverse.lang.directory=PATH_LOCATION_HERE'

If this value is not set, by default, a Dataverse installation will read the English language property files from the Java Application.

See also Internationalization.

dataverse.files.hide-schema-dot-org-download-urls

Please note that this setting is experimental.

By default, download URLs to files will be included in Schema.org JSON-LD output. To prevent these URLs from being included in the output, set dataverse.files.hide-schema-dot-org-download-urls to true as in the example below.

./asadmin create-jvm-options '-Ddataverse.files.hide-schema-dot-org-download-urls=true'

Please note that there are other reasons why download URLs may not be included for certain files such as if a guestbook entry is required or if the file is restricted.

For more on Schema.org JSON-LD, see the Metadata Export section of the Admin Guide.

dataverse.useripaddresssourceheader

Make sure to read the section about the Security Implications of using this option earlier in the guide!

If set, specifies an HTTP Header such as X-Forwarded-For to use to retrieve the user’s IP address. For example:

./asadmin create-jvm-options '-Ddataverse.useripaddresssourceheader=X-Forwarded-For'

This setting is useful in cases such as running your Dataverse installation behind load balancers where the default option of getting the Remote Address from the servlet isn’t correct (e.g. it would be the load balancer IP address). Note that unless your installation always sets the header you configure here, this could be used as a way to spoof the user’s address. Allowed values are:

"X-Forwarded-For",
"Proxy-Client-IP",
"WL-Proxy-Client-IP",
"HTTP_X_FORWARDED_FOR",
"HTTP_X_FORWARDED",
"HTTP_X_CLUSTER_CLIENT_IP",
"HTTP_CLIENT_IP",
"HTTP_FORWARDED_FOR",
"HTTP_FORWARDED",
"HTTP_VIA",
"REMOTE_ADDR"

Application Server Settings

http.request-timeout-seconds

To facilitate large file upload and download, the Dataverse Software installer bumps the Payara server-config.network-config.protocols.protocol.http-listener-1.http.request-timeout-seconds setting from its default 900 seconds (15 minutes) to 1800 (30 minutes). Should you wish to shorten or lengthen this window, issue for example:

./asadmin set server-config.network-config.protocols.protocol.http-listener-1.http.request-timeout-seconds=3600

and restart Payara to apply your change.

Database Settings

These settings are stored in the setting database table but can be read and modified via the “admin” endpoint of the Native API for easy scripting.

The most commonly used configuration options are listed first.

The pattern you will observe in curl examples below is that an HTTP PUT is used to add or modify a setting. If you perform an HTTP GET (the default when using curl), the output will contain the value of the setting, if it has been set. You can also do a GET of all settings with curl http://localhost:8080/api/admin/settings which you may want to pretty-print by piping the output through a tool such as jq by appending | jq .. If you want to remove a setting, use an HTTP DELETE such as curl -X DELETE http://localhost:8080/api/admin/settings/:GuidesBaseUrl .

:BlockedApiPolicy

:BlockedApiPolicy affects access to the list of API endpoints defined in :BlockedApiEndpoints.

Out of the box, localhost-only is the default policy, as mentioned in Blocking API Endpoints. The other valid options are the following.

  • localhost-only: Allow from localhost.

  • unblock-key: Require a key defined in :BlockedApiKey.

  • drop: Disallow the blocked endpoints completely.

Below is an example of setting localhost-only.

curl -X PUT -d localhost-only http://localhost:8080/api/admin/settings/:BlockedApiPolicy

:BlockedApiEndpoints

A comma-separated list of API endpoints to be blocked. For a standard production installation, the installer blocks both “admin” and “builtin-users” by default per the security section above:

curl -X PUT -d "admin,builtin-users" http://localhost:8080/api/admin/settings/:BlockedApiEndpoints

See the Lists of Dataverse APIs for lists of API endpoints.

:BlockedApiKey

:BlockedApiKey is used in conjunction with :BlockedApiEndpoints and :BlockedApiPolicy and will not be enabled unless the policy is set to unblock-key as demonstrated below. Please note that the order is significant. You should set :BlockedApiKey first to prevent locking yourself out.

curl -X PUT -d s3kretKey http://localhost:8080/api/admin/settings/:BlockedApiKey

curl -X PUT -d unblock-key http://localhost:8080/api/admin/settings/:BlockedApiPolicy

Now that :BlockedApiKey has been enabled, blocked APIs can be accessed using the query parameter unblock-key=theKeyYouChose as in the example below.

curl https://demo.dataverse.org/api/admin/settings?unblock-key=theKeyYouChose

BuiltinUsers.KEY

The key required to create users via API as documented at Native API. Unlike other database settings, this one doesn’t start with a colon.

curl -X PUT -d builtInS3kretKey http://localhost:8080/api/admin/settings/BuiltinUsers.KEY

:SearchApiRequiresToken

In Dataverse Software 4.7 and lower, the Search API required an API token, but as of Dataverse Software 4.7.1 this is no longer the case. If you prefer the old behavior of requiring API tokens to use the Search API, set :SearchApiRequiresToken to true.

curl -X PUT -d true http://localhost:8080/api/admin/settings/:SearchApiRequiresToken

:SystemEmail

This is the email address that “system” emails are sent from such as password reset links. Your Dataverse installation will not send mail without this setting in place.

curl -X PUT -d 'LibraScholar SWAT Team <support@librascholar.edu>' http://localhost:8080/api/admin/settings/:SystemEmail

Note that only the email address is required, which you can supply without the < and > signs, but if you include the text, it’s the way to customize the name of your support team, which appears in the “from” address in emails as well as in help text in the UI.

Please note that if you’re having any trouble sending email, you can refer to “Troubleshooting” under Installation.

:FooterCopyright

By default the footer says “Copyright © [YYYY]” but you can add text after the year, as in the example below.

curl -X PUT -d ", Your Institution" http://localhost:8080/api/admin/settings/:FooterCopyright

:DoiProvider

As of this writing “DataCite” and “EZID” are the only valid options for production installations. Developers using Dataverse Software 4.10+ are welcome to use the keyword “FAKE” to configure a non-production installation with an non-resolving, in-code provider, which will basically short-circuit the DOI publishing process. :DoiProvider is only needed if you are using DOI.

curl -X PUT -d DataCite http://localhost:8080/api/admin/settings/:DoiProvider

This setting relates to the :Protocol, :Authority, :Shoulder, and :IdentifierGenerationStyle database settings below as well as the following JVM options:

:Protocol

As of this writing “doi” and “hdl” are the only valid option for the protocol for a persistent ID.

curl -X PUT -d doi http://localhost:8080/api/admin/settings/:Protocol

:Authority

Use the authority assigned to you by your DoiProvider or HandleProvider.

Please note that the authority cannot have a slash (“/”) in it.

curl -X PUT -d 10.xxxx http://localhost:8080/api/admin/settings/:Authority

:Shoulder

Out of the box, the DOI shoulder is set to “FK2/” but this is for testing only! When you apply for your DOI namespace, you may have requested a shoulder. The following is only an example and a trailing slash is optional.

curl -X PUT -d "MyShoulder/" http://localhost:8080/api/admin/settings/:Shoulder

:IdentifierGenerationStyle

By default, the Dataverse Software generates a random 6 character string, pre-pended by the Shoulder if set, to use as the identifier for a Dataset. Set this to storedProcGenerated to generate instead a custom unique identifier (again pre-pended by the Shoulder if set) through a database stored procedure or function (the assumed default setting is randomString). In addition to this setting, a stored procedure or function must be created in the database.

As a first example, the script below (downloadable here) produces sequential numerical values. You may need to make some changes to suit your system setup, see the comments for more information:

-- A script for creating a numeric identifier sequence, and an external
-- stored procedure, for accessing the sequence from inside the application,
-- in a non-hacky, JPA way.

-- NOTE:

-- 1. The database user name "dvnapp" is hard-coded here - it may
-- need to be changed to match your database user name;

-- 2. In the code below, the sequence starts with 1, but it can be adjusted by
-- changing the MINVALUE as needed.

CREATE SEQUENCE datasetidentifier_seq
  INCREMENT 1
  MINVALUE 1
  MAXVALUE 9223372036854775807
  START 1
CACHE 1;

ALTER TABLE datasetidentifier_seq OWNER TO "dvnapp";

-- And now create a PostgreSQL FUNCTION, for JPA to
-- access as a NamedStoredProcedure:

CREATE OR REPLACE FUNCTION generateIdentifierFromStoredProcedure()
RETURNS varchar AS $$
DECLARE
  identifier varchar;
BEGIN
  identifier := nextval('datasetidentifier_seq')::varchar;
  RETURN identifier;
END;
$$ LANGUAGE plpgsql IMMUTABLE;

As a second example, the script below (downloadable here) produces sequential 8 character identifiers from a base36 representation of current timestamp.

-- A script for creating, through a database stored procedure, sequential
-- 8 character identifiers from a base36 representation of current timestamp.

CREATE OR REPLACE FUNCTION base36_encode(
  IN digits bigint, IN min_width int = 0)
RETURNS varchar AS $$
DECLARE
    chars char[];
    ret varchar;
    val bigint;
BEGIN
    chars := ARRAY[
      '0','1','2','3','4','5','6','7','8','9',
      'a','b','c','d','e','f','g','h','i','j',
      'k','l','m','n','o','p','q','r','s','t',
      'u','v','w','x','y','z'];
    val := digits;
    ret := '';
    IF val < 0 THEN
        val := val * -1;
    END IF;
    WHILE val != 0 LOOP
        ret := chars[(val % 36)+1] || ret;
        val := val / 36;
    END LOOP;

    IF min_width > 0 AND char_length(ret) < min_width THEN
        ret := lpad(ret, min_width, '0');
    END IF;

    RETURN ret;
END;
$$ LANGUAGE plpgsql IMMUTABLE;


CREATE OR REPLACE FUNCTION generateIdentifierFromStoredProcedure()
RETURNS varchar AS $$
DECLARE
    curr_time_msec bigint;
    identifier varchar;
BEGIN
    curr_time_msec := extract(epoch from now())*1000;
    identifier := base36_encode(curr_time_msec);
    RETURN identifier;
END;
$$ LANGUAGE plpgsql IMMUTABLE;

Note that the SQL in these examples scripts is Postgres-specific. If necessary, it can be reimplemented in any other SQL flavor - the standard JPA code in the application simply expects the database to have a saved function (“stored procedure”) named generateIdentifierFromStoredProcedure() returning a single varchar argument.

Please note that :IdentifierGenerationStyle also plays a role for the “identifier” for files. See the section on :DataFilePIDFormat below for more details.

:DataFilePIDFormat

This setting controls the way that the “identifier” component of a file’s persistent identifier (PID) relates to the PID of its “parent” dataset.

By default the identifier for a file is dependent on its parent dataset. For example, if the identifier of a dataset is “TJCLKP”, the identifier for a file within that dataset will consist of the parent dataset’s identifier followed by a slash (“/”), followed by a random 6 character string, yielding “TJCLKP/MLGWJO”. Identifiers in this format are what you should expect if you leave :DataFilePIDFormat undefined or set it to DEPENDENT and have not changed the :IdentifierGenerationStyle setting from its default.

Alternatively, the identifier for File PIDs can be configured to be independent of Dataset PIDs using the setting INDEPENDENT. In this case, file PIDs will not contain the PIDs of their parent datasets, and their PIDs will be generated the exact same way that datasets’ PIDs are, based on the :IdentifierGenerationStyle setting described above (random 6 character strings or custom unique identifiers through a stored procedure, pre-pended by any shoulder).

The chart below shows examples from each possible combination of parameters from the two settings. :IdentifierGenerationStyle can be either randomString (the default) or storedProcGenerated and :DataFilePIDFormat can be either DEPENDENT (the default) or INDEPENDENT. In the examples below the “identifier” for the dataset is “TJCLKP” for randomString and “100001” for storedProcGenerated (when using sequential numerical values, as described in :IdentifierGenerationStyle above), or “krby26qt” for storedProcGenerated (when using base36 timestamps, as described in :IdentifierGenerationStyle above).

randomString

storedProcGenerated

(sequential numbers)

storedProcGenerated

(base36 timestamps)

DEPENDENT

TJCLKP/MLGWJO

100001/1

krby26qt/1

INDEPENDENT

MLGWJO

100002

krby27pz

As seen above, in cases where :IdentifierGenerationStyle is set to storedProcGenerated and :DataFilePIDFormat is set to DEPENDENT, each file within a dataset will be assigned a number within that dataset starting with “1”.

Otherwise, if :DataFilePIDFormat is set to INDEPENDENT, each file within the dataset is assigned with a new PID which is the next available identifier provided from the database stored procedure. In our example: “100002” when using sequential numbers or “krby27pz” when using base36 timestamps.

:FilePIDsEnabled

Toggles publishing of file-based PIDs for the entire installation. By default this setting is absent and Dataverse Software assumes it to be true. If enabled, the registration will be performed asynchronously (in the background) during publishing of a dataset.

If you don’t want to register file-based PIDs for your installation, set:

curl -X PUT -d 'false' http://localhost:8080/api/admin/settings/:FilePIDsEnabled

Note: File-level PID registration was added in Dataverse Software 4.9; it could not be disabled until Dataverse Software 4.9.3.

:IndependentHandleService

Specific for Handle PIDs. Set this setting to true if you want to use a Handle service which is setup to work ‘independently’ (No communication with the Global Handle Registry). By default this setting is absent and the Dataverse Software assumes it to be false.

curl -X PUT -d 'true' http://localhost:8080/api/admin/settings/:IndependentHandleService

:HandleAuthHandle

Specific for Handle PIDs. Set this setting to <prefix>/<suffix> to be used on a global handle service when the public key is NOT stored in the default handle. By default this setting is absent and the Dataverse Software assumes it to be not set. If the public key for instance is stored in handle: 21.T12996/USER01. For this handle the prefix is ‘21.T12996’ and the suffix is ‘USER01’. The command to execute is then:

curl -X PUT -d '21.T12996/USER01' http://localhost:8080/api/admin/settings/:HandleAuthHandle

:FileValidationOnPublishEnabled

Toggles validation of the physical files in the dataset when it’s published, by recalculating the checksums and comparing against the values stored in the DataFile table. By default this setting is absent and the Dataverse Software assumes it to be true. If enabled, the validation will be performed asynchronously, similarly to how we handle assigning persistent identifiers to datafiles, with the dataset locked for the duration of the publishing process.

If you don’t want the datafiles to be validated on publish, set:

curl -X PUT -d 'false' http://localhost:8080/api/admin/settings/:FileValidationOnPublishEnabled

:ApplicationTermsOfUse

Upload an default language HTML file containing the Terms of Use to be displayed at sign up. Supported HTML tags are listed under the Dataset + File Management section of the User Guide.

curl -X PUT -d@/tmp/apptou.html http://localhost:8080/api/admin/settings/:ApplicationTermsOfUse

To upload a language specific Terms of Use file,

curl -X PUT -d@/tmp/apptou_fr.html http://localhost:8080/api/admin/settings/:ApplicationTermsOfUse/lang/fr

To delete language specific option,

curl -X DELETE http://localhost:8080/api/admin/settings/:ApplicationTermsOfUse/lang/fr

:ApplicationPrivacyPolicyUrl

Specify a URL where users can read your Privacy Policy, linked from the bottom of the page.

curl -X PUT -d https://dataverse.org/best-practices/harvard-dataverse-privacy-policy http://localhost:8080/api/admin/settings/:ApplicationPrivacyPolicyUrl

:ApiTermsOfUse

Specify a URL where users can read your API Terms of Use. API users can retrieve this URL from the SWORD Service Document or the Info section of our Native API documentation.

curl -X PUT -d https://dataverse.org/best-practices/harvard-api-tou http://localhost:8080/api/admin/settings/:ApiTermsOfUse

:ExcludeEmailFromExport

See also Privacy Considerations above.

Set :ExcludeEmailFromExport to prevent email addresses for contacts from being exposed in XML or JSON representations of dataset and Dataverse collection metadata. For a list exported formats such as DDI, see the Metadata Export section of the Admin Guide.

curl -X PUT -d true http://localhost:8080/api/admin/settings/:ExcludeEmailFromExport

Note: After making a change to this setting, a reExportAll needs to be run before the changes will be reflected in the exports:

curl http://localhost:8080/api/admin/metadata/reExportAll

This will force a re-export of every published, local dataset, regardless of whether it has already been exported or not.

The call returns a status message informing the administrator, that the process has been launched ({"status":"WORKFLOW_IN_PROGRESS"}). The administrator can check the progress of the process via log files: [Payara directory]/glassfish/domains/domain1/logs/export_[time stamp].log.

:GuidesBaseUrl

Set GuidesBaseUrl to override the default value “http://guides.dataverse.org”. If you are interested in writing your own version of the guides, you may find the Writing Documentation section of the Developer Guide helpful.

curl -X PUT -d http://dataverse.example.edu http://localhost:8080/api/admin/settings/:GuidesBaseUrl

:GuidesVersion

Set :GuidesVersion to override the version number in the URL of guides. For example, rather than http://guides.dataverse.org/en/4.6/user/account.html the version is overriden to http://guides.dataverse.org/en/1234-new-feature/user/account.html in the example below:

curl -X PUT -d 1234-new-feature http://localhost:8080/api/admin/settings/:GuidesVersion

:MetricsUrl

Make the metrics component on the root Dataverse collection a clickable link to a website where you present metrics on your Dataverse installation, perhaps one of the community-supported tools mentioned in the Reporting Tools and Common Queries section of the Admin Guide.

curl -X PUT -d http://metrics.dataverse.example.edu http://localhost:8080/api/admin/settings/:MetricsUrl

:MaxFileUploadSizeInBytes

This setting controls the maximum size of uploaded files. - To have one limit for all stores, set MaxFileUploadSizeInBytes to “2147483648”, for example, to limit the size of files uploaded to 2 GB:

curl -X PUT -d 2147483648 http://localhost:8080/api/admin/settings/:MaxFileUploadSizeInBytes

  • To have limits per store with an optional default, use a serialized json object for the value of MaxFileUploadSizeInBytes with an entry per store, as in the following example, which maintains a 2 GB default and adds higher limits for stores with ids “fileOne” and “s3”.

curl -X PUT -d '{"default":"2147483648","fileOne":"4000000000","s3":"8000000000"}' http://localhost:8080/api/admin/settings/:MaxFileUploadSizeInBytes

Notes:

  • For SWORD, this size is limited by the Java Integer.MAX_VALUE of 2,147,483,647. (see: https://github.com/IQSS/dataverse/issues/2169)

  • If the MaxFileUploadSizeInBytes is NOT set, uploads, including SWORD may be of unlimited size.

  • For larger file upload sizes, you may need to configure your reverse proxy timeout. If using apache2 (httpd) with Shibboleth, add a timeout to the ProxyPass defined in etc/httpd/conf.d/ssl.conf (which is described in the Shibboleth setup).

:MultipleUploadFilesLimit

This setting controls the number of files that can be uploaded through the UI at once. The default is 1000. It should be set to 1 or higher since 0 has no effect. To limit the number of files in a zip file, see :ZipUploadFilesLimit.

curl -X PUT -d 500 http://localhost:8080/api/admin/settings/:MultipleUploadFilesLimit

:ZipDownloadLimit

For performance reasons, your Dataverse installation will only allow creation of zip files up to 100 MB, but the limit can be increased. Here’s an example of raising the limit to 1 GB:

curl -X PUT -d 1000000000 http://localhost:8080/api/admin/settings/:ZipDownloadLimit

In the UI, users trying to download a zip file larger than the Dataverse installation’s :ZipDownloadLimit will receive messaging that the zip file is too large, and the user will be presented with alternate access options.

:TabularIngestSizeLimit

Threshold in bytes for limiting whether or not “ingest” it attempted for tabular files (which can be resource intensive). For example, with the below in place, files greater than 2 GB in size will not go through the ingest process:

curl -X PUT -d 2000000000 http://localhost:8080/api/admin/settings/:TabularIngestSizeLimit

(You can set this value to 0 to prevent files from being ingested at all.)

You can override this global setting on a per-format basis for the following formats:

  • DTA

  • POR

  • SAV

  • Rdata

  • CSV

  • XLSX

For example, if you want your Dataverse installation to not attempt to ingest Rdata files larger than 1 MB, use this setting:

curl -X PUT -d 1000000 http://localhost:8080/api/admin/settings/:TabularIngestSizeLimit:Rdata

:ZipUploadFilesLimit

Limit the number of files in a zip that your Dataverse installation will accept. In the absence of this setting, your Dataverse instalation defaults to a limit of 1,000 files per zipfile.

curl -X PUT -d 2048 http://localhost:8080/api/admin/settings/:ZipUploadFilesLimit

:SolrHostColonPort

By default your Dataverse installation will attempt to connect to Solr on port 8983 on localhost. Use this setting to change the hostname or port. You must restart Payara after making this change.

curl -X PUT -d localhost:8983 http://localhost:8080/api/admin/settings/:SolrHostColonPort

:SolrFullTextIndexing

Whether or not to index the content of files such as PDFs. The default is false.

curl -X PUT -d true http://localhost:8080/api/admin/settings/:SolrFullTextIndexing

:SolrMaxFileSizeForFullTextIndexing

If :SolrFullTextIndexing is set to true, the content of files of any size will be indexed. To set a limit in bytes for which files to index in this way:

curl -X PUT -d 314572800 http://localhost:8080/api/admin/settings/:SolrMaxFileSizeForFullTextIndexing

:SignUpUrl

The relative path URL to which users will be sent for signup. The default setting is below.

curl -X PUT -d '/dataverseuser.xhtml?editMode=CREATE' http://localhost:8080/api/admin/settings/:SignUpUrl

:LoginSessionTimeout

Session timeout (in minutes) for logged-in users. The default is 8 hours (480 minutes). For the anonymous user sessions, the timeout is set to the default value, configured in the web.xml file of the Dataverse installation.

In the example below we reduce the timeout to 4 hours:

curl -X PUT -d 240 http://localhost:8080/api/admin/settings/:LoginSessionTimeout

:DatasetPublishPopupCustomText

Set custom text a user will view when publishing a dataset. Note that this text is exposed via the “Info” endpoint of the Native API.

curl -X PUT -d "Deposit License Requirements" http://localhost:8080/api/admin/settings/:DatasetPublishPopupCustomText

If you have a long text string, you can upload it as a file as in the example below.

curl -X PUT --upload-file /tmp/long.txt http://localhost:8080/api/admin/settings/:DatasetPublishPopupCustomText

:DatasetPublishPopupCustomTextOnAllVersions

Set whether a user will see the custom text when publishing all versions of a dataset

curl -X PUT -d true http://localhost:8080/api/admin/settings/:DatasetPublishPopupCustomTextOnAllVersions

:SearchHighlightFragmentSize

Set SearchHighlightFragmentSize to override the default value of 100 from https://wiki.apache.org/solr/HighlightingParameters#hl.fragsize . In practice, a value of “320” seemed to fix the issue at https://github.com/IQSS/dataverse/issues/2191

curl -X PUT -d 320 http://localhost:8080/api/admin/settings/:SearchHighlightFragmentSize

:ScrubMigrationData

Allow for migration of non-conformant data (especially dates) from Dataverse Software 3.x to Dataverse Software 4.x

:MinutesUntilConfirmEmailTokenExpires

The duration in minutes before “Confirm Email” URLs expire. The default is 1440 minutes (24 hours). See also the User Administration section of our Admin Guide.

:DefaultAuthProvider

If you have enabled Shibboleth and/or one or more OAuth providers, you may wish to make one of these authentication providers the default when users visit the Log In page. If unset, this will default to builtin but these valid options (depending if you’ve done the setup described in the Shibboleth or OAuth Login Options sections) are:

  • builtin

  • shib

  • orcid

  • github

  • google

Here is an example of setting the default auth provider back to builtin:

curl -X PUT -d builtin http://localhost:8080/api/admin/settings/:DefaultAuthProvider

:AllowSignUp

Set to false to disallow local accounts from being created. See also the sections on Shibboleth and OAuth Login Options.

curl -X PUT -d 'false' http://localhost:8080/api/admin/settings/:AllowSignUp

:FileFixityChecksumAlgorithm

The Dataverse Software calculates checksums for uploaded files so that users can determine if their file was corrupted via upload or download. This is sometimes called “file fixity”: https://en.wikipedia.org/wiki/File_Fixity

The default checksum algorithm used is MD5 and should be sufficient for establishing file fixity. “SHA-1”, “SHA-256” and “SHA-512” are alternate values for this setting. For example:

curl -X PUT -d 'SHA-512' http://localhost:8080/api/admin/settings/:FileFixityChecksumAlgorithm

The fixity algorithm used on existing files can be changed by a superuser using the API. An optional query parameter (num) can be used to limit the number of updates attempted. The API call will only update the algorithm and checksum for a file if the existing checksum can be validated against the file. Statistics concerning the updates are returned in the response to the API call with details in the log.

curl http://localhost:8080/api/admin/updateHashValues/{alg} curl http://localhost:8080/api/admin/updateHashValues/{alg}?num=1

:PVMinLength

Password policy setting for builtin user accounts: a password’s minimum valid character length. The default is 6.

curl -X PUT -d 6 http://localhost:8080/api/admin/settings/:PVMinLength

:PVMaxLength

Password policy setting for builtin user accounts: a password’s maximum valid character length.

curl -X PUT -d 0 http://localhost:8080/api/admin/settings/:PVMaxLength

:PVNumberOfConsecutiveDigitsAllowed

By default, passwords can contain an unlimited number of digits in a row. However, if your password policy specifies otherwise (e.g. only four digits in a row are allowed), then you can issue the following curl command to set the number of consecutive digits allowed (this example uses 4):

curl -X PUT -d 4 http://localhost:8080/api/admin/settings/:PVNumberOfConsecutiveDigitsAllowed

:PVCharacterRules

Password policy setting for builtinuser accounts: dictates which types of characters can be required in a password. This setting goes hand-in-hand with :PVNumberOfCharacteristics. The default setting contains two rules:

  • one letter

  • one digit

The default setting above is equivalent to specifying “Alphabetical:1,Digit:1”.

By specifying “UpperCase:1,LowerCase:1,Digit:1,Special:1”, for example, you can put the following four rules in place instead:

  • one uppercase letter

  • one lowercase letter

  • one digit

  • one special character

If you have implemented 4 different character rules in this way, you can also optionally increase :PVNumberOfCharacteristics to as high as 4. However, please note that :PVNumberOfCharacteristics cannot be set to a number higher than the number of character rules or you will see the error, “Number of characteristics must be <= to the number of rules”.

Also note that the Alphabetical setting should not be used in tandem with the UpperCase or LowerCase settings. The Alphabetical setting encompasses both of those more specific settings, so using it with them will cause your password policy to be unnecessarily confusing, and potentially easier to bypass.

curl -X PUT -d 'UpperCase:1,LowerCase:1,Digit:1,Special:1' http://localhost:8080/api/admin/settings/:PVCharacterRules

curl -X PUT -d 3 http://localhost:8080/api/admin/settings/:PVNumberOfCharacteristics

:PVNumberOfCharacteristics

Password policy setting for builtin user accounts: the number indicates how many of the character rules defined by :PVCharacterRules are required as part of a password. The default is 2. :PVNumberOfCharacteristics cannot be set to a number higher than the number of rules or you will see the error, “Number of characteristics must be <= to the number of rules”.

curl -X PUT -d 2 http://localhost:8080/api/admin/settings/:PVNumberOfCharacteristics

:PVDictionaries

Password policy setting for builtin user accounts: set a comma separated list of dictionaries containing words that cannot be used in a user password. /usr/share/dict/words is suggested and shown modified below to not contain words 3 letters or less. You are free to choose a different dictionary. By default, no dictionary is checked.

DIR=THE_PATH_YOU_WANT_YOUR_DICTIONARY_TO_RESIDE sed '/^.\{,3\}$/d' /usr/share/dict/words > $DIR/pwdictionary curl -X PUT -d "$DIR/pwdictionary" http://localhost:8080/api/admin/settings/:PVDictionaries

:PVGoodStrength

Password policy setting for builtin user accounts: passwords of equal or greater character length than the :PVGoodStrength setting are always valid, regardless of other password constraints.

curl -X PUT -d 20 http://localhost:8080/api/admin/settings/:PVGoodStrength

Recommended setting: 20.

:PVCustomPasswordResetAlertMessage

Changes the default info message displayed when a user is required to change their password on login. The default is:

{0} Reset Password{1} – Our password requirements have changed. Please pick a strong password that matches the criteria below.

Where the {0} and {1} denote surrounding HTML bold tags. It’s recommended to put a single space before your custom message for better appearance (as in the default message above). Including the {0} and {1} to bolden part of your message is optional.

Customize the message using the following curl command’s syntax:

curl -X PUT -d '{0} Action Required:{1} Your current password does not meet all requirements. Please enter a new password meeting the criteria below.' http://localhost:8080/api/admin/settings/:PVCustomPasswordResetAlertMessage

:ShibPassiveLoginEnabled

Set :ShibPassiveLoginEnabled to true to enable passive login for Shibboleth. When this feature is enabled, an additional Javascript file (isPassive.js) will be loaded for every page. It will generate a passive login request to your Shibboleth SP when an anonymous user navigates to the site. A cookie named “_check_is_passive_dv” will be created to keep track of whether or not a passive login request has already been made for the user.

This implementation follows the example on the Shibboleth wiki documentation page for the isPassive feature: https://wiki.shibboleth.net/confluence/display/SHIB2/isPassive

It is recommended that you configure additional error handling for your Service Provider if you enable passive login. A good way of doing this is described in the Shibboleth wiki documentation:

  • In your Service Provider 2.x shibboleth2.xml file, add redirectErrors=”#THIS PAGE#” to the Errors element.

You can set the value of “#THIS PAGE#” to the URL of your Dataverse installation homepage, or any other page on your site that is accessible to anonymous users and will have the isPassive.js file loaded.

curl -X PUT -d true http://localhost:8080/api/admin/settings/:ShibPassiveLoginEnabled

:ShibAffiliationAttribute

The Shibboleth affiliation attribute holds information about the affiliation of the user (e.g. “OU”) and is read from the DiscoFeed at each login. :ShibAffiliationAttribute is a name of a Shibboleth attribute in the Shibboleth header which your Dataverse installation will read from instead of DiscoFeed. If this value is not set or empty, your Dataverse installation uses the DiscoFeed.

If the attribute is not yet set for the Shibboleth, please consult the Shibboleth Administrators at your institution. Typically it requires changing of the /etc/shibboleth/attribute-map.xml file by adding an attribute request, e.g.

<Attribute name="urn:oid:2.5.4.11" id="ou">
    <AttributeDecoder xsi:type="StringAttributeDecoder" caseSensitive="false"/>
</Attribute>

In order to implement the change, you should restart Shibboleth and Apache2 services:

sudo service shibd restart
sudo service apache2 restart

To check if the attribute is sent, you should log in again to the Dataverse installation and check Shibboleth’s transaction log. You should see something like this:

INFO Shibboleth-TRANSACTION [25]: Cached the following attributes with session (ID: _9d1f34c0733b61c0feb0ca7596ef43b2) for (applicationId: default) {
INFO Shibboleth-TRANSACTION [25]:       givenName (1 values)
INFO Shibboleth-TRANSACTION [25]:       ou (1 values)
INFO Shibboleth-TRANSACTION [25]:       sn (1 values)
INFO Shibboleth-TRANSACTION [25]:       eppn (1 values)
INFO Shibboleth-TRANSACTION [25]:       mail (1 values)
INFO Shibboleth-TRANSACTION [25]:       displayName (1 values)
INFO Shibboleth-TRANSACTION [25]: }

If you see the attribue you requested in this list, you can set the attribute in the Dataverse installation.

To set :ShibAffiliationAttribute:

curl -X PUT -d "ou" http://localhost:8080/api/admin/settings/:ShibAffiliationAttribute

To delete :ShibAffiliationAttribute:

curl -X DELETE http://localhost:8080/api/admin/settings/:ShibAffiliationAttribute

To check the current value of :ShibAffiliationAttribute:

curl -X GET http://localhost:8080/api/admin/settings/:ShibAffiliationAttribute

:ShibAttributeCharacterSetConversionEnabled

It seems that the application server (usually Glassfish or Payara) will interpret all Shibboleth attributes that come through AJP as ISO-8859-1, even if they where originally UTF-8. To circumvent that, we re-encode all received Shibboleth attributes manually as UTF-8 by default. In the case you get garbled characters in Shibboleth-supplied fields (e.g. given name, surname, affiliation), you can disable this behaviour by setting ShibAttributeCharacterSetConversionEnabled to false:

curl -X PUT -d false http://localhost:8080/api/admin/settings/:ShibAttributeCharacterSetConversionEnabled

If you managed to get correct accented characters from shibboleth while this setting is _false_, please contact us with your application server and Shibboleth configuration!

:ComputeBaseUrl

Set the base URL for the “Compute” button for a dataset.

curl -X PUT -d 'https://giji.massopencloud.org/application/dataverse' http://localhost:8080/api/admin/settings/:ComputeBaseUrl

:CloudEnvironmentName

Set the name of the cloud environment you’ve integrated with your Dataverse installation.

curl -X PUT -d 'Massachusetts Open Cloud (MOC)' http://localhost:8080/api/admin/settings/:CloudEnvironmentName

:PublicInstall

Setting an installation to public will remove the ability to restrict data files or datasets. This functionality of the Dataverse Software will be disabled from your installation.

This is useful for specific cases where an installation’s files are stored in public access. Because files stored this way do not obey the Dataverse Software’s file restrictions, users would still be able to access the files even when they’re restricted. In these cases it’s best to use :PublicInstall to disable the feature altogether.

curl -X PUT -d true http://localhost:8080/api/admin/settings/:PublicInstall

:DataCaptureModuleUrl

The URL for your Data Capture Module (DCM) installation. This component is experimental and can be downloaded from https://github.com/sbgrid/data-capture-module .

curl -X PUT -d 'https://dcm.example.edu' http://localhost:8080/api/admin/settings/:DataCaptureModuleUrl

:RepositoryStorageAbstractionLayerUrl

The URL for your Repository Storage Abstraction Layer (RSAL) installation. This component is experimental and can be downloaded from https://github.com/sbgrid/rsal .

curl -X PUT -d 'https://rsal.example.edu' http://localhost:8080/api/admin/settings/:RepositoryStorageAbstractionLayerUrl

:UploadMethods

This setting controls which upload methods are available to users of your Dataverse installation. The following upload methods are available:

  • native/http: Corresponds to “Upload with HTTP via your browser” and APIs that use HTTP (SWORD and native).

  • dcm/rsync+ssh: Corresponds to “Upload with rsync+ssh via Data Capture Module (DCM)”. A lot of setup is required, as explained in the Big Data Support section of the Developer Guide.

Out of the box only native/http is enabled and will work without further configuration. To add multiple upload method, separate them using a comma like this:

curl -X PUT -d 'native/http,dcm/rsync+ssh' http://localhost:8080/api/admin/settings/:UploadMethods

You’ll always want at least one upload method, so the easiest way to remove one of them is to simply PUT just the one you want, like this:

curl -X PUT -d 'native/http' http://localhost:8080/api/admin/settings/:UploadMethods

:DownloadMethods

This setting is experimental and related to Repository Storage Abstraction Layer (RSAL).

curl -X PUT -d 'rsal/rsync' http://localhost:8080/api/admin/settings/:DownloadMethods

:GuestbookResponsesPageDisplayLimit

Limit on how many guestbook entries to display on the guestbook-responses page. By default, only the 5000 most recent entries will be shown. Use the standard settings API in order to change the limit. For example, to set it to 10,000, make the following API call:

curl -X PUT -d 10000 http://localhost:8080/api/admin/settings/:GuestbookResponsesPageDisplayLimit

:CustomDatasetSummaryFields

You can replace the default dataset metadata fields that are displayed above files table on the dataset page with a custom list separated by commas using the curl command below.

curl http://localhost:8080/api/admin/settings/:CustomDatasetSummaryFields -X PUT -d 'producer,subtitle,alternativeTitle'

You have to put the datasetFieldType name attribute in the :CustomDatasetSummaryFields setting for this to work.

:AllowApiTokenLookupViaApi

The Dataverse Software 4.8.1 and below allowed API Token lookup via API but for better security this has been disabled by default. Set this to true if you really want the old behavior.

curl -X PUT -d 'true' http://localhost:8080/api/admin/settings/:AllowApiTokenLookupViaApi

:ProvCollectionEnabled

Enable the collection of provenance metadata on your Dataverse installation via the provenance popup.

curl -X PUT -d 'true' http://localhost:8080/api/admin/settings/:ProvCollectionEnabled

:MetricsCacheTimeoutMinutes

Sets how long a cached metrics result is used before re-running the query for a request. This timeout is only applied to some of the metrics that query the current state of the system, previous months queries are cached indefinitely. See Metrics API for more info. The default timeout value is 7 days (10080 minutes).

curl -X PUT -d 10080 http://localhost:8080/api/admin/settings/:MetricsCacheTimeoutMinutes

:MDCLogPath

Sets the path where the raw Make Data Count logs are stored before being processed. If not set, no logs will be created for Make Data Count. See also the Make Data Count section of the Admin Guide.

curl -X PUT -d '/usr/local/payara5/glassfish/domains/domain1/logs' http://localhost:8080/api/admin/settings/:MDCLogPath

:DisplayMDCMetrics

:DisplayMDCMetrics can be set to false to disable display of MDC metrics (e.g. to enable collection of MDC metrics for some period prior to completing the set-up of Counter and performing the other steps described in the Make Data Count section of the Admin Guide).

curl -X PUT -d 'false' http://localhost:8080/api/admin/settings/:DisplayMDCMetrics

:Languages

Sets which languages should be available. If there is more than one, a dropdown is displayed in the header.

See Internationalization for a curl example and related settings.

:MetadataLanguages

Sets which languages can be used when entering dataset metadata.

See Internationalization for further discussion, a curl example, and related settings.

:InheritParentRoleAssignments

:InheritParentRoleAssignments can be set to a comma-separated list of role aliases or ‘*’ (all) to cause newly created Dataverse collections to inherit the set of users and/or internal groups who have assignments for those role(s) on the parent Dataverse collection, i.e. those users/groups will be assigned the same role(s) on the new Dataverse collection (in addition to the creator of the new Dataverse collection having an admin role). This can be helpful in situations where multiple organizations are sharing one Dataverse installation. The default, if :InheritParentRoleAssignments is not set is for the creator of the new Dataverse collection to be the only one assigned a role.

curl -X PUT -d 'admin, curator' http://localhost:8080/api/admin/settings/:InheritParentRoleAssignments or curl -X PUT -d '*' http://localhost:8080/api/admin/settings/:InheritParentRoleAssignments

:AllowCors

Allows Cross-Origin Resource sharing(CORS). By default this setting is absent and the Dataverse Software assumes it to be true.

If you don’t want to allow CORS for your installation, set:

curl -X PUT -d 'false' http://localhost:8080/api/admin/settings/:AllowCors

:ChronologicalDateFacets

Unlike other facets, those indexed by Date/Year are sorted chronologically by default, with the most recent value first. To have them sorted by number of hits, e.g. with the year with the most results first, set this to false

If you don’t want date facets to be sorted chronologically, set:

curl -X PUT -d 'false' http://localhost:8080/api/admin/settings/:ChronologicalDateFacets

:CustomZipDownloadServiceUrl

The location of the “Standalone Zipper” service. If this option is specified, the Dataverse installation will be redirecing bulk/multi-file zip download requests to that location, instead of serving them internally. See Standalone “Zipper” Service Tool of the Advanced Installation guide for information on how to install the external zipper. (This is still an experimental feature, as of Dataverse Software 5.0).

To enable redirects to the zipper installed on the same server as the main Dataverse Software application:

curl -X PUT -d '/cgi-bin/zipdownload' http://localhost:8080/api/admin/settings/:CustomZipDownloadServiceUrl

To enable redirects to the zipper on a different server:

curl -X PUT -d 'https://zipper.example.edu/cgi-bin/zipdownload' http://localhost:8080/api/admin/settings/:CustomZipDownloadServiceUrl

:ArchiverClassName

Your Dataverse installation can export archival “Bag” files to an extensible set of storage systems (see BagIt Export above for details about this and for further explanation of the other archiving related settings below). This setting specifies which storage system to use by identifying the particular Java class that should be run. Current options include DuraCloudSubmitToArchiveCommand, LocalSubmitToArchiveCommand, and GoogleCloudSubmitToArchiveCommand.

curl -X PUT -d 'LocalSubmitToArchiveCommand' http://localhost:8080/api/admin/settings/:ArchiverClassName

:ArchiverSettings

Each Archiver class may have its own custom settings. Along with setting which Archiver class to use, one must use this setting to identify which setting values should be sent to it when it is invoked. The value should be a comma-separated list of setting names. For example, the LocalSubmitToArchiveCommand only uses the :BagItLocalPath setting. To allow the class to use that setting, this setting must set as:

curl -X PUT -d ':BagItLocalPath' http://localhost:8080/api/admin/settings/:ArchiverSettings

:DuraCloudContext

These three settings define the host, port, and context used by the DuraCloudSubmitToArchiveCommand. :DuraCloudHost is required. The other settings have default values as noted in the Duracloud Configuration section above.

:BagItLocalPath

This is the local file system path to be used with the LocalSubmitToArchiveCommand class. It is recommended to use an absolute path. See the Local Path Configuration section above.

:GoogleCloudProject

These are the bucket and project names to be used with the GoogleCloudSubmitToArchiveCommand class. Further information is in the Google Cloud Configuration section above.

:InstallationName

By default, the name of the root Dataverse collection is used as the ‘brandname’ of the repository, i.e. in emails and metadata exports. If set, :InstallationName overrides this default, allowing the root collection name and brandname to be set independently. (Note that, since metadata export files are cached, they will have to be reexported (see Metadata Export) before they incorporate a change in this setting.)

:ExportInstallationAsDistributorOnlyWhenNotSet

In the DDI metadata exports, the default behavior is to always add the repository (using its brandname - the root collection name or the value of :InstallationName) to the stdyDscr/distStmt/distrbtr element. If this setting is true, this will only be done when a Distributor is not already defined in the Dataset metadata. (Note that, since metadata export files are cached, they will have to be reexported (see Metadata Export) before they incorporate a change in this setting.)

:AnonymizedFieldTypeNames

A comma-separated list of field type names that should be ‘withheld’ when dataset access occurs via a Private Url with Anonymized Access (e.g. to support anonymized review). A suggested minimum includes author, datasetContact, and contributor, but additional fields such as depositor, grantNumber, and publication might also need to be included.

curl -X PUT -d 'author, datasetContact, contributor, depositor, grantNumber, publication' http://localhost:8080/api/admin/settings/:AnonymizedFieldTypeNames

:DatasetChecksumValidationSizeLimit

Setting DatasetChecksumValidationSizeLimit to a threshold in bytes, disables the checksum validation while publishing for any dataset size greater than the limit.

For example, if you want your Dataverse installation to skip validation for any dataset larger than 5 GB while publishing, use this setting:

curl -X PUT -d 5000000000 http://localhost:8080/api/admin/settings/:DatasetChecksumValidationSizeLimit

When this option is used to disable the checksum validation, it’s strongly recommended to perform periodic asynchronous checks via the integrity API

Refer to “Physical Files Validation in a Dataset” API Physical Files Validation in a Dataset section of our Native API documentation.

Also refer to the “Datafile Integrity” API Datafile Integrity

:DataFileChecksumValidationSizeLimit

Setting DataFileChecksumValidationSizeLimit to a threshold in bytes, disables the checksum validation while publishing for any datafiles greater than the limit.

For example, if you want your Dataverse installation to skip validation for any data files larger than 2 GB while publishing, use this setting:

curl -X PUT -d 2000000000 http://localhost:8080/api/admin/settings/:DataFileChecksumValidationSizeLimit

When this option is used to disable the checksum validation, it’s strongly recommended to perform periodic asynchronous checks via the integrity API

Refer to “Physical Files Validation in a Dataset” API Physical Files Validation in a Dataset section of our Native API documentation.

Also refer to the “Datafile Integrity” API Datafile Integrity

:SendNotificationOnDatasetCreation

A boolean setting that, if true, will send an email and notification to users when a Dataset is created. Messages go to those, other than the dataset creator, who have the ability/permission necessary to publish the dataset. The intent of this functionality is to simplify tracking activity and planning to follow-up contact.

curl -X PUT -d true http://localhost:8080/api/admin/settings/:SendNotificationOnDatasetCreation

:CVocConf

A JSON-structured setting that configures Dataverse to associate specific metadatablock fields with external vocabulary services and specific vocabularies/sub-vocabularies managed by that service. More information about this capability is available at Metadata Customization.

Scripts that implement this association for specific service protocols are maintained at https://github.com/gdcc/dataverse-external-vocab-support. That repository also includes a json-schema for validating the structure required by this setting along with an example metadatablock and sample :CVocConf setting values associating entries in the example block with ORCID and SKOSMOS based services.

wget https://gdcc.github.io/dataverse-external-vocab-support/examples/config/cvoc-conf.json

curl -X PUT --upload-file cvoc-conf.json http://localhost:8080/api/admin/settings/:CVocConf

:AllowedCurationLabels

A JSON Object containing lists of allowed labels (up to 32 characters, spaces allowed) that can be set, via API or UI by users with the permission to publish a dataset. The set of labels allowed for datasets can be selected by a superuser - via the Dataverse collection page (Edit/General Info) or set via API call. The labels in a set should correspond to the states in an organization’s curation process and are intended to help users/curators track the progress of a dataset through a defined curation process. A dataset may only have one label at a time and if a label is set, it will be removed at publication time. This functionality is disabled when this setting is empty/not set. Each set of labels is identified by a curationLabelSet name and a JSON Array of the labels allowed in that set.

curl -X PUT -d '{"Standard Process":["Author contacted", "Privacy Review", "Awaiting paper publication", "Final Approval"], "Alternate Process":["State 1","State 2","State 3"]}' http://localhost:8080/api/admin/settings/:AllowedCurationLabels

:AllowCustomTermsOfUse

By default, custom terms of data use and access can be specified after selecting “Custom Terms” from the License/DUA dropdown on the Terms tab. When :AllowCustomTermsOfUse is set to false the “Custom Terms” item is not made available to the depositor.

curl -X PUT -d false http://localhost:8080/api/admin/settings/:AllowCustomTermsOfUse

:MaxEmbargoDurationInMonths

This setting controls whether embargoes are allowed in a Dataverse instance and can limit the maximum duration users are allowed to specify. A value of 0 months or non-existent setting indicates embargoes are not supported. A value of -1 allows embargoes of any length. Any other value indicates the maximum number of months (from the current date) a user can enter for an embargo end date. This limit will be enforced in the popup dialog in which users enter the embargo date. For example, to set a two year maximum:

curl -X PUT -d 24 http://localhost:8080/api/admin/settings/:MaxEmbargoDurationInMonths

:DataverseMetadataValidatorScript

An optional external script that validates Dataverse collection metadata as it’s being updated or published. The script provided should be an executable that takes a single command line argument, the name of the file containing the metadata exported in the native json format. I.e., Dataverse application will be exporting the collection metadata in json format, saving it in a temp file, and passing the name of the temp file to the validation script as the command line argument. The script should exit with a non-zero error code if the validation fails. If that happens, a failure message (customizable in the next two settings below, :DataverseMetadataPublishValidationFailureMsg and :DataverseMetadataUpdateValidationFailureMsg) will be shown to the user.

For example, once the following setting is created:

curl -X PUT -d /usr/local/bin/dv_validator.sh http://localhost:8080/api/admin/settings/:DataverseMetadataValidatorScript

:DataverseMetadataPublishValidationFailureMsg

Specifies a custom error message shown to the user when a Dataverse collection fails an external metadata validation (as specified in the setting above) during an attempt to publish. If not specified, the default message “This dataverse collection cannot be published because it has failed an external metadata validation test” will be used.

For example:

curl -X PUT -d "This content needs to go through an additional review by the Curation Team before it can be published." http://localhost:8080/api/admin/settings/:DataverseMetadataPublishValidationFailureMsg

:DataverseMetadataUpdateValidationFailureMsg

Same as above, but specifies a custom error message shown to the user when an external metadata validation check fails during an attempt to modify a Dataverse collection. If not specified, the default message “This dataverse collection cannot be updated because it has failed an external metadata validation test” will be used.

:DatasetMetadataValidatorScript

An optional external script that validates dataset metadata during publishing. The script provided should be an executable that takes a single command line argument, the name of the file containing the metadata exported in the native json format. I.e., Dataverse application will be exporting the dataset metadata in json format, saving it in a temp file, and passing the name of the file to the validation script as the command line argument. The script should exit with a non-zero error code if the validation fails. If that happens, the dataset is left unpublished, and a failure message (customizable in the next setting below, :DatasetMetadataValidationFailureMsg) will be shown to the user.

For example:

curl -X PUT -d /usr/local/bin/ds_validator.sh http://localhost:8080/api/admin/settings/:DatasetMetadataValidatorScript

In some ways this duplicates a workflow mechanism, since it is possible to define a workflow with additonal validation steps. But please note that the important difference is that this external validation happens synchronously, while the user is wating; while a workflow is performed asynchronously with a lock placed on the dataset. This can be useful to some installations, in some situations. But it also means that the script provided should be expected to always work reasonably fast - ideally, in seconds, rather than minutes, etc.

:DatasetMetadataValidationFailureMsg

Specifies a custom error message shown to the user when a dataset fails an external metadata validation (as specified in the setting above) during an attempt to publish. If not specified, the default message “This dataset cannot be published because it has failed an external metadata validation test” will be used.

For example:

curl -X PUT -d "This content needs to go through an additional review by the Curation Team before it can be published." http://localhost:8080/api/admin/settings/:DatasetMetadataValidationFailureMsg

:ExternalValidationAdminOverride

When set to true, this setting allows a superuser to publish and/or update Dataverse collections and datasets bypassing the external validation checks (specified by the settings above). In an event where an external script is reporting validation failures that appear to be in error, this option gives an admin with superuser privileges a quick way to publish the dataset or update a collection for the user.
