Native API

Dataverse 4 exposes most of its GUI functionality via a REST-based API. This section describes that functionality. Most API endpoints require an API token that can be passed as the X-Dataverse-key HTTP header or in the URL as the key query parameter.

Note

CORS Some API endpoint allow CORS (cross-origin resource sharing), which makes them usable from scripts running in web browsers. These endpoints are marked with a CORS badge.

Note

Bash environment variables shown below. The idea is that you can “export” these environment variables before copying and pasting the commands that use them. For example, you can set $SERVER_URL by running export SERVER_URL="https://demo.dataverse.org" in your Bash shell. To check if the environment variable was set properly, you can “echo” it (e.g. echo $SERVER_URL). See also curl Examples and Environment Variables.

Warning

Dataverse 4’s API is versioned at the URI - all API calls may include the version number like so: http://server-address/api/v1/.... Omitting the v1 part would default to the latest API version (currently 1). When writing scripts/applications that will be used for a long time, make sure to specify the API version, so they don’t break when the API is upgraded.

Create a Dataverse

A dataverse is a container for datasets and other dataverses as explained in the Dataverse Management section of the User Guide.

The steps for creating a dataverse are:

  • Prepare a JSON file containing the name, description, etc, of the dataverse you’d like to create.
  • Figure out the alias or database id of the “parent” dataverse into which you will be creating your new dataverse.
  • Execute a curl command or equivalent.

Download dataverse-complete.json file and modify it to suit your needs. The fields name, alias, and dataverseContacts are required. The controlled vocabulary for dataverseType is the following:

  • DEPARTMENT
  • JOURNALS
  • LABORATORY
  • ORGANIZATIONS_INSTITUTIONS
  • RESEARCHERS
  • RESEARCH_GROUP
  • RESEARCH_PROJECTS
  • TEACHING_COURSES
  • UNCATEGORIZED
{
  "name": "Scientific Research",
  "alias": "science",
  "dataverseContacts": [
    {
      "contactEmail": "pi@example.edu"
    },
    {
      "contactEmail": "student@example.edu"
    }
  ],
  "affiliation": "Scientific Research University",
  "description": "We do all the science.",
  "dataverseType": "LABORATORY"
}

The curl command below assumes you have kept the name “dataverse-complete.json” and that this file is in your current working directory.

Next you need to figure out the alias or database id of the “parent” dataverse into which you will be creating your new dataverse. Out of the box the top level dataverse has an alias of “root” and a database id of “1” but your installation may vary. The easiest way to determine the alias of your root dataverse is to click “Advanced Search” and look at the URL. You may also choose a parent under the root.

Note

See curl Examples and Environment Variables if you are unfamiliar with the use of export below.

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PARENT=root

curl -H X-Dataverse-key:$API_TOKEN -X POST $SERVER_URL/api/dataverses/$PARENT --upload-file dataverse-complete.json

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx -X POST https://demo.dataverse.org/api/dataverses/root --upload-file dataverse-complete.json

You should expect an HTTP 200 response and JSON beginning with “status”:”OK” followed by a representation of the newly-created dataverse.

View a Dataverse

CORS View a JSON representation of the dataverse identified by $id. $id can be the database ID of the dataverse, its alias, or the special value :root for the root dataverse.

To view a published dataverse:

export SERVER_URL=https://demo.dataverse.org
export ID=root

curl $SERVER_URL/api/dataverses/$ID

The fully expanded example above (without environment variables) looks like this:

curl https://demo.dataverse.org/api/dataverses/root

To view an unpublished dataverse:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=root

curl -H X-Dataverse-key:$API_TOKEN $SERVER_URL/api/dataverses/$ID

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx https://demo.dataverse.org/api/dataverses/root

Delete a Dataverse

Before you may delete a dataverse you must first delete or move all of its contents elsewhere.

Deletes the dataverse whose database ID or alias is given:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=root

curl -H X-Dataverse-key:$API_TOKEN -X DELETE $SERVER_URL/api/dataverses/$ID

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx -X DELETE https://demo.dataverse.org/api/dataverses/root

Show Contents of a Dataverse

CORS Lists all the dataverses and datasets directly under a dataverse (direct children only, not recursive) specified by database id or alias. If you pass your API token and have access, unpublished dataverses and datasets will be included in the response.

Note

See curl Examples and Environment Variables if you are unfamiliar with the use of export below.

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=root

curl -H X-Dataverse-key:$API_TOKEN $SERVER_URL/api/dataverses/$ID/contents

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx https://demo.dataverse.org/api/dataverses/root/contents

Report the data (file) size of a Dataverse

Shows the combined size in bytes of all the files uploaded into the dataverse id:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=root

curl -H X-Dataverse-key:$API_TOKEN $SERVER_URL/api/dataverses/$ID/storagesize

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx https://demo.dataverse.org/api/dataverses/root/storagesize

The size of published and unpublished files will be summed both in the dataverse specified and beneath all its sub-dataverses, recursively. By default, only the archival files are counted - i.e., the files uploaded by users (plus the tab-delimited versions generated for tabular data files on ingest). If the optional argument includeCached=true is specified, the API will also add the sizes of all the extra files generated and cached by Dataverse - the resized thumbnail versions for image files, the metadata exports for published datasets, etc.

List Roles Defined in a Dataverse

All the roles defined directly in the dataverse identified by id:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=root

curl -H X-Dataverse-key:$API_TOKEN $SERVER_URL/api/dataverses/$ID/roles

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx -X POST https://demo.dataverse.org/api/dataverses/root/facets --upload-file facets.json

Where facets.json contains a JSON encoded list of metadata keys (e.g. ["authorName","authorAffiliation"]).

Create a New Role in a Dataverse

Creates a new role under dataverse id. Needs a json file with the role description:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx https://demo.dataverse.org/api/dataverses/root/assignments

Assign Default Role to User Creating a Dataset in a Dataverse

Assign a default role to a user creating a dataset in a dataverse id where roleAlias is the database alias of the role to be assigned:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=root
export ROLE_ALIAS=curator

curl -H X-Dataverse-key:$API_TOKEN -X PUT $SERVER_URL/api/dataverses/$ID/defaultContributorRole/$ROLE_ALIAS

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx -X PUT https://demo.dataverse.org/api/dataverses/root/defaultContributorRole/curator

Note: You may use “none” as the ROLE_ALIAS. This will prevent a user who creates a dataset from having any role on that dataset. It is not recommended for dataverses with human contributors.

Assign a New Role on a Dataverse

Assigns a new role, based on the POSTed JSON:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

POSTed JSON example (the content of role.json file):

{
  "assignee": "@uma",
  "role": "curator"
}

Delete Role Assignment from a Dataverse

Delete the assignment whose id is $id:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=root
export ASSIGNMENT_ID=6

List Metadata Blocks Defined on a Dataverse

CORS Get the metadata blocks defined on a dataverse which determine which field are available to authors when they create and edit datasets within that dataverse. This feature is described in General Information section of Dataverse Management of the User Guide.

Please note that an API token is only required if the dataverse has not been published.

Note

See curl Examples and Environment Variables if you are unfamiliar with the use of export below.

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=root

curl -H X-Dataverse-key:$API_TOKEN $SERVER_URL/api/dataverses/$ID/metadatablocks

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx https://demo.dataverse.org/api/dataverses/root/metadatablocks

Define Metadata Blocks for a Dataverse

You can define the metadata blocks available to authors within a dataverse.

The metadata blocks that are available with a default installation of Dataverse are in define-metadatablocks.json (also shown below) and you should download this file and edit it to meet your needs. Please note that the “citation” metadata block is required. You must have “EditDataverse” permission on the dataverse.

[
  "citation",
  "geospatial",
  "socialscience",
  "astrophysics",
  "biomedical",
  "journal"
]

Note

See curl Examples and Environment Variables if you are unfamiliar with the use of export below.

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=root

curl -H X-Dataverse-key:$API_TOKEN -X POST $SERVER_URL/api/dataverses/$ID/metadatablocks -H \"Content-type:application/json\" --upload-file define-metadatablocks.json

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx -X POST -H "Content-type:application/json" --upload-file define-metadatablocks.json https://demo.dataverse.org/api/dataverses/root/metadatablocks

Determine if a Dataverse Inherits Its Metadata Blocks from Its Parent

Get whether the dataverse is a metadata block root, or does it uses its parent blocks:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=root

curl -H X-Dataverse-key:$API_TOKEN $SERVER_URL/api/dataverses/$ID/metadatablocks/isRoot

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx https://demo.dataverse.org/api/dataverses/root/metadatablocks/isRoot

Configure a Dataverse to Inherit Its Metadata Blocks from Its Parent

Set whether the dataverse is a metadata block root, or does it uses its parent blocks. Possible values are true and false (both are valid JSON expressions):

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=root

curl -H X-Dataverse-key:$API_TOKEN -X PUT $SERVER_URL/api/dataverses/$ID/metadatablocks/isRoot

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx -X PUT https://demo.dataverse.org/api/dataverses/root/metadatablocks/isRoot

Note

Previous endpoints $SERVER/api/dataverses/$id/metadatablocks/:isRoot and POST http://$SERVER/api/dataverses/$id/metadatablocks/:isRoot?key=$apiKey are deprecated, but supported.

Create a Dataset in a Dataverse

A dataset is a container for files as explained in the Dataset + File Management section of the User Guide.

To create a dataset, you must supply a JSON file that contains at least the following required metadata fields:

  • Title
  • Author
  • Contact
  • Description
  • Subject

As a starting point, you can download dataset-finch1.json and modify it to meet your needs. (In addition to this minimal example, you can download dataset-create-new-all-default-fields.json which populates all of the metadata fields that ship with Dataverse.)

The curl command below assumes you have kept the name “dataset-finch1.json” and that this file is in your current working directory.

Next you need to figure out the alias or database id of the “parent” dataverse into which you will be creating your new dataset. Out of the box the top level dataverse has an alias of “root” and a database id of “1” but your installation may vary. The easiest way to determine the alias of your root dataverse is to click “Advanced Search” and look at the URL. You may also choose a parent dataverse under the root dataverse.

Note

See curl Examples and Environment Variables if you are unfamiliar with the use of export below.

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export PARENT=root
export SERVER_URL=https://demo.dataverse.org

curl -H X-Dataverse-key:$API_TOKEN -X POST "$SERVER_URL/api/dataverses/$PARENT/datasets" --upload-file dataset-finch1.json

The fully expanded example above (without the environment variables) looks like this:

curl -H "X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X POST "https://demo.dataverse.org/api/dataverses/root/datasets" --upload-file "dataset-finch1.json"

You should expect an HTTP 200 (“OK”) response and JSON indicating the database ID and Persistent ID (PID such as DOI or Handle) that has been assigned to your newly created dataset.

Note

Only a Dataverse account with superuser permissions is allowed to include files when creating a dataset via this API. Adding files this way only adds their file metadata to the database, you will need to manually add the physical files to the file system.

Import a Dataset into a Dataverse

Note

This action requires a Dataverse account with super-user permissions.

To import a dataset with an existing persistent identifier (PID), the dataset’s metadata should be prepared in Dataverse’s native JSON format. The PID is provided as a parameter at the URL. The following line imports a dataset with the PID PERSISTENT_IDENTIFIER to Dataverse, and then releases it:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export DATAVERSE_ID=root
export PERSISTENT_IDENTIFIER=doi:ZZ7/MOSEISLEYDB94

curl -H X-Dataverse-key:$API_TOKEN -X POST $SERVER_URL/api/dataverses/$DATAVERSE_ID/datasets/:import?pid=$PERSISTENT_IDENTIFIER&release=yes --upload-file dataset.json

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx -X POST https://demo.dataverse.org/api/dataverses/root/datasets/:import?pid=doi:ZZ7/MOSEISLEYDB94&release=yes --upload-file dataset.json

The pid parameter holds a persistent identifier (such as a DOI or Handle). The import will fail if no PID is provided, or if the provided PID fails validation.

The optional release parameter tells Dataverse to immediately publish the dataset. If the parameter is changed to no, the imported dataset will remain in DRAFT status.

The JSON format is the same as that supported by the native API’s create dataset command, although it also allows packages. For example:

{
  "datasetVersion": {
    "termsOfUse": "CC0 Waiver",
    "license": "CC0",
    "protocol":"doi",
    "authority":"10.502",

        }
      }
    ]
  }
}

Before calling the API, make sure the data files referenced by the POSTed JSON are placed in the dataset directory with filenames matching their specified storage identifiers. In installations using POSIX storage, these files must be made readable by the app server user.

Tip

If possible, it’s best to avoid spaces and special characters in the storage identifier in order to avoid potential portability problems. The storage identifier corresponds with the filesystem name (or bucket identifier) of the data file, so these characters may cause unpredictability with filesystem tools.

Warning

  • This API does not cover staging files (with correct contents, checksums, sizes, etc.) in the corresponding places in the Dataverse filestore.
  • This API endpoint does not support importing files’ persistent identifiers.
  • A Dataverse server can import datasets with a valid PID that uses a different protocol or authority than said server is configured for. However, the server will not update the PID metadata on subsequent update and publish actions.

Import a Dataset into a Dataverse with a DDI file

Note

This action requires a Dataverse account with super-user permissions.

To import a dataset with an existing persistent identifier (PID), you have to provide the PID as a parameter at the URL. The following line imports a dataset with the PID PERSISTENT_IDENTIFIER to Dataverse, and then releases it:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export DATAVERSE_ID=root
export PERSISTENT_IDENTIFIER=doi:ZZ7/MOSEISLEYDB94

curl -H X-Dataverse-key:$API_TOKEN -X POST $SERVER_URL/api/dataverses/$DATAVERSE_ID/datasets/:importddi?pid=$PERSISTENT_IDENTIFIER&release=yes --upload-file ddi_dataset.xml

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx -X POST https://demo.dataverse.org/api/dataverses/root/datasets/:importddi?pid=doi:ZZ7/MOSEISLEYDB94&release=yes --upload-file ddi_dataset.xml

The optional pid parameter holds a persistent identifier (such as a DOI or Handle). The import will fail if the provided PID fails validation.

The optional release parameter tells Dataverse to immediately publish the dataset. If the parameter is changed to no, the imported dataset will remain in DRAFT status.

The file is a DDI xml file.

Warning

  • This API does not handle files related to the DDI file.
  • A Dataverse server can import datasets with a valid PID that uses a different protocol or authority than said server is configured for. However, the server will not update the PID metadata on subsequent update and publish actions.

Publish a Dataverse

In order to publish a dataverse, you must know either its “alias” (which the GUI calls an “identifier”) or its database ID.

Note

See curl Examples and Environment Variables if you are unfamiliar with the use of export below.

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=root

curl -H X-Dataverse-key:$API_TOKEN -X POST $SERVER_URL/api/dataverses/$ID/actions/:publish

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx -X POST https://demo.dataverse.org/api/dataverses/root/actions/:publish

You should expect a 200 (“OK”) response and JSON output.

Datasets

Note Creation of new datasets is done with a POST onto dataverses. See Dataverses section.

Note In all commands below, dataset versions can be referred to as:

  • :draft the draft version, if any
  • :latest either a draft (if exists) or the latest published version.
  • :latest-published the latest published version
  • x.y a specific version, where x is the major version number and y is the minor version number.
  • x same as x.0

Get JSON Representation of a Dataset

Note

Datasets can be accessed using persistent identifiers. This is done by passing the constant :persistentId where the numeric id of the dataset is expected, and then passing the actual persistent id as a query parameter with the name persistentId.

Example: Getting the dataset whose DOI is 10.5072/FK2/J8SJZB:

export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_IDENTIFIER=doi:10.5072/FK2/J8SJZB

curl $SERVER_URL/api/datasets/:persistentId/?persistentId=$PERSISTENT_IDENTIFIER

The fully expanded example above (without environment variables) looks like this:

curl https://demo.dataverse.org/api/datasets/:persistentId/?persistentId=doi:10.5072/FK2/J8SJZB

Getting its draft version:

export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_IDENTIFIER=doi:10.5072/FK2/J8SJZB

curl http://$SERVER/api/datasets/:persistentId/versions/:draft?persistentId=$PERSISTENT_IDENTIFIER

The fully expanded example above (without environment variables) looks like this:

curl https://demo.dataverse.org/api/datasets/:persistentId/versions/:draft?persistentId=doi:10.5072/FK2/J8SJZB

CORS Show the dataset whose id is passed:

export SERVER_URL=https://demo.dataverse.org
export ID=408730

curl $SERVER_URL/api/datasets/$ID

The fully expanded example above (without environment variables) looks like this:

curl https://demo.dataverse.org/api/datasets/408730

The dataset id can be extracted from the response retrieved from the API which uses the persistent identifier (/api/datasets/:persistentId/?persistentId=$PERSISTENT_IDENTIFIER).

List Versions of a Dataset

CORS List versions of the dataset:

export SERVER_URL=https://demo.dataverse.org
export ID=24

curl $SERVER_URL/api/dataverses/$ID/versions

The fully expanded example above (without environment variables) looks like this:

curl https://demo.dataverse.org/api/datasets/24/versions

Get Version of a Dataset

CORS Show a version of the dataset. The output includes any metadata blocks the dataset might have:

export SERVER_URL=https://demo.dataverse.org
export ID=24
export VERSION=1.0

curl $SERVER_URL/api/datasets/$ID/versions/$VERSION

The fully expanded example above (without environment variables) looks like this:

curl https://demo.dataverse.org/api/datasets/24/versions/1.0

Export Metadata of a Dataset in Various Formats

CORS Export the metadata of the current published version of a dataset in various formats see Note below:

export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_IDENTIFIER=doi:10.5072/FK2/J8SJZB
export METADATA_FORMAT=ddi

curl $SERVER_URL/api/datasets/export?exporter=$METADATA_FORMAT&persistentId=PERSISTENT_IDENTIFIER

The fully expanded example above (without environment variables) looks like this:

curl https://demo.dataverse.org/api/datasets/export?exporter=ddi&persistentId=doi:10.5072/FK2/J8SJZB

Note

Supported exporters (export formats) are ddi, oai_ddi, dcterms, oai_dc, schema.org , OAI_ORE , Datacite, oai_datacite and dataverse_json. Descriptive names can be found under Supported Metadata Export Formats in the User Guide.

Schema.org JSON-LD

Please note that the schema.org format has changed in backwards-incompatible ways after Dataverse 4.9.4:

  • “description” was a single string and now it is an array of strings.
  • “citation” was an array of strings and now it is an array of objects.

Both forms are valid according to Google’s Structured Data Testing Tool at https://search.google.com/structured-data/testing-tool . (This tool will report “The property affiliation is not recognized by Google for an object of type Thing” and this known issue is being tracked at https://github.com/IQSS/dataverse/issues/5029 .) Schema.org JSON-LD is an evolving standard that permits a great deal of flexibility. For example, https://schema.org/docs/gs.html#schemaorg_expected indicates that even when objects are expected, it’s ok to just use text. As with all metadata export formats, we will try to keep the Schema.org JSON-LD format Dataverse emits backward-compatible to made integrations more stable, despite the flexibility that’s afforded by the standard.

List Files in a Dataset

CORS Lists all the file metadata, for the given dataset and version:

export SERVER_URL=https://demo.dataverse.org
export ID=24
export VERSION=1.0

curl $SERVER_URL/api/datasets/$ID/versions/$VERSION/files

The fully expanded example above (without environment variables) looks like this:

curl https://demo.dataverse.org/api/datasets/24/versions/1.0/files

List All Metadata Blocks for a Dataset

CORS Lists all the metadata blocks and their content, for the given dataset and version:

export SERVER_URL=https://demo.dataverse.org
export ID=24
export VERSION=1.0

curl $SERVER_URL/api/datasets/$ID/versions/$VERSION/metadata

The fully expanded example above (without environment variables) looks like this:

curl https://demo.dataverse.org/api/datasets/24/versions/1.0/metadata

List Single Metadata Block for a Dataset

CORS Lists the metadata block named METADATA_BLOCK, for the given dataset and version:

export SERVER_URL=https://demo.dataverse.org
export ID=24
export VERSION=1.0
export METADATA_BLOCK=citation

curl $SERVER_URL/api/datasets/$ID/versions/$VERSION/metadata/$METADATA_BLOCK

The fully expanded example above (without environment variables) looks like this:

curl https://demo.dataverse.org/api/datasets/24/versions/1.0/metadata/citation

Update Metadata For a Dataset

Updates the metadata for a dataset. If a draft of the dataset already exists, the metadata of that draft is overwritten; otherwise, a new draft is created with this metadata.

You must download a JSON representation of the dataset, edit the JSON you download, and then send the updated JSON to the Dataverse server.

For example, after making your edits, your JSON file might look like dataset-update-metadata.json which you would send to Dataverse like this:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_IDENTIFIER=doi:10.5072/FK2/BCCP9Z

curl -H "X-Dataverse-key: $API_TOKEN" -X PUT $SERVER_URL/api/datasets/:persistentId/versions/:draft?persistentId=$PERSISTENT_IDENTIFIER --upload-file dataset-update-metadata.json

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X PUT https://demo.dataverse.org/api/datasets/:persistentId/versions/:draft?persistentId=doi:10.5072/FK2/BCCP9Z --upload-file dataset-update-metadata.json

Note that in the example JSON file above, there is a single JSON object with metadataBlocks as a key. When you download a representation of your dataset in JSON format, the metadataBlocks object you need is nested inside another object called json. To extract just the metadataBlocks key when downloading a JSON representation, you can use a tool such as jq like this:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_IDENTIFIER=doi:10.5072/FK2/BCCP9Z

curl -H "X-Dataverse-key: $API_TOKEN" $SERVER_URL/api/datasets/:persistentId/versions/:latest?persistentId=$PERSISTENT_IDENTIFIER | jq '.data | {metadataBlocks: .metadataBlocks}' > dataset-update-metadata.json

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" https://demo.dataverse.org/api/datasets/:persistentId/versions/:latest?persistentId=doi:10.5072/FK2/BCCP9Z | jq '.data | {metadataBlocks: .metadataBlocks}' > dataset-update-metadata.json

Now that the resulting JSON file only contains the metadataBlocks key, you can edit the JSON such as with vi in the example below:

vi dataset-update-metadata.json

Now that you’ve made edits to the metadata in your JSON file, you can send it to Dataverse as described above.

Edit Dataset Metadata

Alternatively to replacing an entire dataset version with its JSON representation you may add data to dataset fields that are blank or accept multiple values with the following:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_IDENTIFIER=doi:10.5072/FK2/BCCP9Z

curl -H "X-Dataverse-key: $API_TOKEN" -X PUT $SERVER_URL/api/datasets/:persistentId/editMetadata/?persistentId=$PERSISTENT_IDENTIFIER --upload-file dataset-add-metadata.json

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X PUT https://demo.dataverse.org/api/datasets/:persistentId/editMetadata/?persistentId=doi:10.5072/FK2/BCCP9Z --upload-file dataset-add-metadata.json

You may also replace existing metadata in dataset fields with the following (adding the parameter replace=true):

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_IDENTIFIER=doi:10.5072/FK2/BCCP9Z

curl -H "X-Dataverse-key: $API_TOKEN" -X PUT $SERVER_URL/api/datasets/:persistentId/editMetadata?persistentId=$PERSISTENT_IDENTIFIER&replace=true --upload-file dataset-update-metadata.json

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X PUT https://demo.dataverse.org/api/datasets/:persistentId/editMetadata/?persistentId=doi:10.5072/FK2/BCCP9Z&replace=true --upload-file dataset-update-metadata.json

For these edits your JSON file need only include those dataset fields which you would like to edit. A sample JSON file may be downloaded here: dataset-edit-metadata-sample.json

Delete Dataset Metadata

You may delete some of the metadata of a dataset version by supplying a file with a JSON representation of dataset fields that you would like to delete with the following:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_IDENTIFIER=doi:10.5072/FK2/BCCP9Z

curl -H "X-Dataverse-key: $API_TOKEN" -X PUT $SERVER_URL/api/datasets/:persistentId/deleteMetadata/?persistentId=$PERSISTENT_IDENTIFIER --upload-file dataset-delete-author-metadata.json

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X PUT https://demo.dataverse.org/api/datasets/:persistentId/deleteMetadata/?persistentId=doi:10.5072/FK2/BCCP9Z --upload-file dataset-delete-author-metadata.json

For these deletes your JSON file must include an exact match of those dataset fields which you would like to delete. A sample JSON file may be downloaded here: dataset-delete-author-metadata.json

Publish a Dataset

When publishing a dataset it’s good to be aware of Dataverse’s versioning system, which is described in the Dataset + File Management section of the User Guide.

If this is the first version of the dataset, its version number will be set to 1.0. Otherwise, the new dataset version number is determined by the most recent version number and the type parameter. Passing type=minor increases the minor version number (2.3 is updated to 2.4). Passing type=major increases the major version number (2.3 is updated to 3.0). (Superusers can pass type=updatecurrent to update metadata without changing the version number.)

Note

See curl Examples and Environment Variables if you are unfamiliar with the use of export below.

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_ID=doi:10.5072/FK2/J8SJZB
export MAJOR_OR_MINOR=major

curl -H "X-Dataverse-key: $API_TOKEN" -X POST "$SERVER_URL/api/datasets/:persistentId/actions/:publish?persistentId=$PERSISTENT_ID&type=$MAJOR_OR_MINOR"

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X POST "https://demo.dataverse.org/api/datasets/:persistentId/actions/:publish?persistentId=doi:10.5072/FK2/J8SJZB&type=major"

The quotes around the URL are required because there is more than one query parameter separated by an ampersand (&), which has special meaning to Unix shells such as Bash. Putting the & in quotes ensures that “type” is interpreted as one of the query parameters.

You should expect JSON output and a 200 (“OK”) response in most cases. If you receive a 202 (“ACCEPTED”) response, this is normal for installations that have workflows configured. Workflows are described in the Workflows section of the Developer Guide.

Note

POST should be used to publish a dataset. GET is supported for backward compatibility but is deprecated and may be removed: https://github.com/IQSS/dataverse/issues/2431

Delete Dataset Draft

Deletes the draft version of dataset $ID. Only the draft version can be deleted:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X DELETE https://demo.dataverse.org/api/datasets/24/privateUrl

Add a File to a Dataset

When adding a file to a dataset, you can optionally specify the following:

  • A description of the file.
  • The “File Path” of the file, indicating which folder the file should be uploaded to within the dataset.
  • Whether or not the file is restricted.

In the curl example below, all of the above are specified but they are optional.

Note

See curl Examples and Environment Variables if you are unfamiliar with the use of export below.

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export FILENAME='data.tsv'
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_ID=doi:10.5072/FK2/J8SJZB

curl -H X-Dataverse-key:$API_TOKEN -X POST -F "file=@$FILENAME" -F 'jsonData={"description":"My description.","directoryLabel":"data/subdir1","categories":["Data"], "restrict":"false"}' "$SERVER_URL/api/datasets/:persistentId/add?persistentId=$PERSISTENT_ID"

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx -X POST -F file=@data.tsv -F 'jsonData={"description":"My description.","directoryLabel":"data/subdir1","categories":["Data"], "restrict":"false"}' "https://demo.dataverse.org/api/datasets/:persistentId/add?persistentId=doi:10.5072/FK2/J8SJZB"

You should expect a 201 (“CREATED”) response and JSON indicating the database id that has been assigned to your newly uploaded file.

Please note that it’s possible to “trick” Dataverse into giving a file a content type (MIME type) of your choosing. For example, you can make a text file be treated like a video file with -F 'file=@README.txt;type=video/mpeg4', for example. If Dataverse does not properly detect a file type, specifying the content type via API like this a potential workaround.

The curl syntax above to upload a file is tricky and a Python version is provided below. (Please note that it depends on libraries such as “requests” that you may need to install but this task is out of scope for this guide.) Here are some parameters you can set in the script:

  • dataverse_server - e.g. https://demo.dataverse.org
  • api_key - See the top of this document for a description
  • persistentId - Example: doi:10.5072/FK2/6XACVA
  • dataset_id - Database id of the dataset

In practice, you only need one the dataset_id or the persistentId. The example below shows both uses.

from datetime import datetime
import json
import requests  # http://docs.python-requests.org/en/master/

# --------------------------------------------------
# Update the 4 params below to run this code
# --------------------------------------------------
dataverse_server = 'https://your dataverse server' # no trailing slash
api_key = 'api key'
dataset_id = 1  # database id of the dataset
persistentId = 'doi:10.5072/FK2/6XACVA' # doi or hdl of the dataset

# --------------------------------------------------
# Prepare "file"
# --------------------------------------------------
file_content = 'content: %s' % datetime.now()
files = {'file': ('sample_file.txt', file_content)}

# --------------------------------------------------
# Using a "jsonData" parameter, add optional description + file tags
# --------------------------------------------------
params = dict(description='Blue skies!',
            categories=['Lily', 'Rosemary', 'Jack of Hearts'])

params_as_json_string = json.dumps(params)

payload = dict(jsonData=params_as_json_string)

# --------------------------------------------------
# Add file using the Dataset's id
# --------------------------------------------------
url_dataset_id = '%s/api/datasets/%s/add?key=%s' % (dataverse_server, dataset_id, api_key)

# -------------------
# Make the request
# -------------------
print '-' * 40
print 'making request: %s' % url_dataset_id
r = requests.post(url_dataset_id, data=payload, files=files)

# -------------------
# Print the response
# -------------------
print '-' * 40
print r.json()
print r.status_code

# --------------------------------------------------
# Add file using the Dataset's persistentId (e.g. doi, hdl, etc)
# --------------------------------------------------
url_persistent_id = '%s/api/datasets/:persistentId/add?persistentId=%s&key=%s' % (dataverse_server, persistentId, api_key)

# -------------------
# Update the file content to avoid a duplicate file error
# -------------------
file_content = 'content2: %s' % datetime.now()
files = {'file': ('sample_file2.txt', file_content)}


# -------------------
# Make the request
# -------------------
print '-' * 40
print 'making request: %s' % url_persistent_id
r = requests.post(url_persistent_id, data=payload, files=files)

# -------------------
# Print the response
# -------------------
print '-' * 40
print r.json()
print r.status_code

Report the data (file) size of a Dataset

Shows the combined size in bytes of all the files uploaded into the dataset id.

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=24

curl -H X-Dataverse-key:$API_TOKEN $SERVER_URL/api/datasets/$ID/storagesize

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx https://demo.dataverse.org/api/datasets/24/storagesize

The size of published and unpublished files will be summed in the dataset specified. By default, only the archival files are counted - i.e., the files uploaded by users (plus the tab-delimited versions generated for tabular data files on ingest). If the optional argument includeCached=true is specified, the API will also add the sizes of all the extra files generated and cached by Dataverse - the resized thumbnail versions for image files, the metadata exports for published datasets, etc. Because this deals with unpublished files the token supplied must have permission to view unpublished drafts.

Shows the combined size in bytes of all the files available for download from version versionId of dataset id.

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=24
export VERSIONID=1.0

curl -H X-Dataverse-key:$API_TOKEN $SERVER_URL/api/datasets/$ID/versions/$VERSIONID/downloadsize

The fully expanded example above (without environment variables) looks like this:

curl -H X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx https://demo.dataverse.org/api/datasets/24/versions/1.0/downloadsize

The size of all files available for download will be returned. If :draft is passed as versionId the token supplied must have permission to view unpublished drafts. A token is not required for published datasets. Also restricted files will be included in this total regardless of whether the user has access to download the restricted file(s).

Submit a Dataset for Review

When dataset authors do not have permission to publish directly, they can click the “Submit for Review” button in the web interface (see Dataset + File Management), or perform the equivalent operation via API:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_ID=doi:10.5072/FK2/J8SJZB

curl -H "X-Dataverse-key: $API_TOKEN" -X POST "$SERVER_URL/api/datasets/:persistentId/submitForReview?persistentId=$PERSISTENT_ID"

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X POST "https://demo.dataverse.org/api/datasets/:persistentId/submitForReview?persistentId=doi:10.5072/FK2/J8SJZB"

The people who need to review the dataset (often curators or journal editors) can check their notifications periodically via API to see if any new datasets have been submitted for review and need their attention. See the Notifications section for details. Alternatively, these curators can simply check their email or notifications to know when datasets have been submitted (or resubmitted) for review.

Return a Dataset to Author

After the curators or journal editors have reviewed a dataset that has been submitted for review (see “Submit for Review”, above) they can either choose to publish the dataset (see the :publish “action” above) or return the dataset to its authors. In the web interface there is a “Return to Author” button (see Dataset + File Management), but the interface does not provide a way to explain why the dataset is being returned. There is a way to do this outside of this interface, however. Instead of clicking the “Return to Author” button in the UI, a curator can write a “reason for return” into the database via API.

Here’s how curators can send a “reason for return” to the dataset authors. First, the curator creates a JSON file that contains the reason for return:

{
  "reasonForReturn": "You forgot to upload any files."
}

In the example below, the curator has saved the JSON file as reason-for-return.json in their current working directory. Then, the curator sends this JSON file to the returnToAuthor API endpoint like this:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_ID=doi:10.5072/FK2/J8SJZB

curl -H "X-Dataverse-key: $API_TOKEN" -X POST "$SERVER_URL/api/datasets/:persistentId/returnToAuthor?persistentId=$PERSISTENT_ID" -H "Content-type: application/json" -d @reason-for-return.json

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X POST "https://demo.dataverse.org/api/datasets/:persistentId/returnToAuthor?persistentId=doi:10.5072/FK2/J8SJZB" -H "Content-type: application/json" -d @reason-for-return.json

The review process can sometimes resemble a tennis match, with the authors submitting and resubmitting the dataset over and over until the curators are satisfied. Each time the curators send a “reason for return” via API, that reason is persisted into the database, stored at the dataset version level.

Dataset Locks

To check if a dataset is locked:

export SERVER_URL=https://demo.dataverse.org
export ID=24

curl $SERVER_URL/api/datasets/$ID/locks

The fully expanded example above (without environment variables) looks like this:

curl https://demo.dataverse.org/api/datasets/24/locks

Optionally, you can check if there’s a lock of a specific type on the dataset:

export SERVER_URL=https://demo.dataverse.org
export ID=24
export LOCK_TYPE=Ingest

curl "$SERVER_URL/api/datasets/$ID/locks?type=$LOCK_TYPE"

The fully expanded example above (without environment variables) looks like this:

curl "https://demo.dataverse.org/api/datasets/24/locks?type=Ingest"

Currently implemented lock types are Ingest, Workflow, InReview, DcmUpload, pidRegister, and EditInProgress.

The API will output the list of locks, for example:

{"status":"OK","data":
  [
    {
      "lockType":"Ingest",
      "date":"Fri Aug 17 15:05:51 EDT 2018",
      "user":"dataverseAdmin"
    },
    {
      "lockType":"Workflow",
      "date":"Fri Aug 17 15:02:00 EDT 2018",
      "user":"dataverseAdmin"
    }
  ]
}

If the dataset is not locked (or if there is no lock of the requested type), the API will return an empty list.

The following API end point will lock a Dataset with a lock of specified type:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=24
export LOCK_TYPE=Ingest

curl -H "X-Dataverse-key: $API_TOKEN" -X POST $SERVER_URL/api/datasets/$ID/lock/$LOCK_TYPE

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X POST https://demo.dataverse.org/api/datasets/24/lock/Ingest

Use the following API to unlock the dataset, by deleting all the locks currently on the dataset:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=24

curl -H "X-Dataverse-key: $API_TOKEN" -X DELETE $SERVER_URL/api/datasets/$ID/locks

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X DELETE https://demo.dataverse.org/api/datasets/24/locks

Or, to delete a lock of the type specified only:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=24
export LOCK_TYPE=pidRegister

curl -H "X-Dataverse-key: $API_TOKEN" -X DELETE $SERVER_URL/api/datasets/$ID/locks?type=$LOCK_TYPE

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X DELETE https://demo.dataverse.org/api/datasets/24/locks?type=pidRegister

If the dataset is not locked (or if there is no lock of the specified type), the API will exit with a warning message.

(Note that the API calls above all support both the database id and persistent identifier notation for referencing the dataset)

Dataset Metrics

Please note that these dataset level metrics are only available if support for Make Data Count has been enabled in your installation of Dataverse. See the Dataset Metrics in the Dataset + File Management section of the User Guide and the Make Data Count section of the Admin Guide for details.

Note

See curl Examples and Environment Variables if you are unfamiliar with the use of export below.

export SERVER_URL=https://demo.dataverse.org

To confirm that the environment variable was set properly, you can use echo like this:

echo $SERVER_URL

Please note that for each of these endpoints except the “citations” endpoint, you can optionally pass the query parameter “country” with a two letter code (e.g. “country=us”) and you can specify a particular month by adding it in yyyy-mm format after the requested metric (e.g. “viewsTotal/2019-02”).

Retrieving Total Views for a Dataset

Please note that “viewsTotal” is a combination of “viewsTotalRegular” and “viewsTotalMachine” which can be requested separately.

export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_ID=doi:10.5072/FK2/J8SJZB

curl "$SERVER_URL/api/datasets/:persistentId/makeDataCount/viewsTotal?persistentId=$PERSISTENT_ID"

The fully expanded example above (without environment variables) looks like this:

curl "https://demo.dataverse.org/api/datasets/:persistentId/makeDataCount/viewsTotal?persistentId=10.5072/FK2/J8SJZB"

Retrieving Unique Views for a Dataset

Please note that “viewsUnique” is a combination of “viewsUniqueRegular” and “viewsUniqueMachine” which can be requested separately.

export PERSISTENT_ID=doi:10.5072/FK2/J8SJZB

curl "$SERVER_URL/api/datasets/:persistentId/makeDataCount/viewsUnique?persistentId=$PERSISTENT_ID"

The fully expanded example above (without environment variables) looks like this:

curl "https://demo.dataverse.org/api/datasets/:persistentId/makeDataCount/viewsUnique?persistentId=10.5072/FK2/J8SJZB"

Retrieving Total Downloads for a Dataset

Please note that “downloadsTotal” is a combination of “downloadsTotalRegular” and “downloadsTotalMachine” which can be requested separately.

export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_ID=doi:10.5072/FK2/J8SJZB

curl "$SERVER_URL/api/datasets/:persistentId/makeDataCount/downloadsTotal?persistentId=$PERSISTENT_ID"

The fully expanded example above (without environment variables) looks like this:

curl "https://demo.dataverse.org/api/datasets/:persistentId/makeDataCount/downloadsTotal?persistentId=10.5072/FK2/J8SJZB"

Retrieving Unique Downloads for a Dataset

Please note that “downloadsUnique” is a combination of “downloadsUniqueRegular” and “downloadsUniqueMachine” which can be requested separately.

export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_ID=doi:10.5072/FK2/J8SJZB

curl "$SERVER_URL/api/datasets/:persistentId/makeDataCount/downloadsUnique?persistentId=$PERSISTENT_ID"

The fully expanded example above (without environment variables) looks like this:

curl "https://demo.dataverse.org/api/datasets/:persistentId/makeDataCount/downloadsUnique?persistentId=10.5072/FK2/J8SJZB"

Retrieving Citations for a Dataset

export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_ID=doi:10.5072/FK2/J8SJZB

curl "$SERVER_URL/api/datasets/:persistentId/makeDataCount/citations?persistentId=$PERSISTENT_ID"

The fully expanded example above (without environment variables) looks like this:

curl "https://demo.dataverse.org/api/datasets/:persistentId/makeDataCount/citations?persistentId=10.5072/FK2/J8SJZB"

Delete Unpublished Dataset

Delete the dataset whose id is passed:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=24

curl -H "X-Dataverse-key: $API_TOKEN" -X DELETE $SERVER_URL/api/datasets/$ID

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X DELETE https://demo.dataverse.org/api/datasets/24

Delete Published Dataset

Normally published datasets should not be deleted, but there exists a “destroy” API endpoint for superusers which will act on a dataset given a persistent ID or dataset database ID:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_ID=doi:10.5072/FK2/AAA000

curl -H "X-Dataverse-key: $API_TOKEN" -X DELETE $SERVER_URL/api/datasets/:persistentId/destroy/?persistentId=$PERSISTENT_ID

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X DELETE https://demo.dataverse.org/api/datasets/:persistentId/destroy/?persistentId=doi:10.5072/FK2/AAA000

Delete with dataset identifier:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=24

curl -H "X-Dataverse-key: $API_TOKEN" -X DELETE $SERVER_URL/api/datasets/$ID/destroy

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X DELETE https://demo.dataverse.org/api/datasets/24/destroy

Calling the destroy endpoint is permanent and irreversible. It will remove the dataset and its datafiles, then re-index the parent dataverse in Solr. This endpoint requires the API token of a superuser.

Configure a Dataset to Use a Specific File Store

/api/datasets/$dataset-id/storageDriver can be used to check, configure or reset the designated file store (storage driver) for a dataset. Please see the Managing Datasets and Dataverses section of the guide for more information on this API.

Files

Adding Files

Note

Files can be added via the native API but the operation is performed on the parent object, which is a dataset. Please see the Datasets endpoint above for more information.

Accessing (downloading) files

Note

Access API has its own section in the Guide: Data Access API

Note Data Access API calls can now be made using persistent identifiers (in addition to database ids). This is done by passing the constant :persistentId where the numeric id of the file is expected, and then passing the actual persistent id as a query parameter with the name persistentId.

Example: Getting the file whose DOI is 10.5072/FK2/J8SJZB

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_ID=doi:10.5072/FK2/J8SJZB

curl "$SERVER_URL/api/access/datafile/:persistentId/?persistentId=$PERSISTENT_ID"

The fully expanded example above (without environment variables) looks like this:

curl "https://demo.dataverse.org/api/access/datafile/:persistentId/?persistentId=doi:10.5072/FK2/J8SJZB"

Note: you can use the combination of cURL’s -J (--remote-header-name) and -O (--remote-name) options to save the file in its original file name, such as

curl -J -O "https://demo.dataverse.org/api/access/datafile/:persistentId/?persistentId=doi:10.5072/FK2/J8SJZB"

Restrict Files

Restrict or unrestrict an existing file where id is the database id of the file or pid is the persistent id (DOI or Handle) of the file to restrict. Note that some Dataverse installations do not allow the ability to restrict files.

A curl example using an id

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=24

curl -H "X-Dataverse-key:$API_TOKEN" -X PUT -d true $SERVER_URL/api/files/$ID/restrict

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X PUT -d true https://demo.dataverse.org/api/files/24/restrict

A curl example using a pid

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_ID=doi:10.5072/FK2/AAA000

curl -H "X-Dataverse-key:$API_TOKEN" -X PUT -d true $SERVER_URL/api/files/:persistentId/restrict?persistentId=$PERSISTENT_ID

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X PUT -d true "https://demo.dataverse.org/api/files/:persistentId/restrict?persistentId=doi:10.5072/FK2/AAA000"

Uningest a File

Reverse the tabular data ingest process performed on a file where ID is the database id or PERSISTENT_ID is the persistent id (DOI or Handle) of the file to process. Note that this requires “superuser” credentials.

A curl example using an ID:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=24

curl -H "X-Dataverse-key:$API_TOKEN" -X POST $SERVER_URL/api/files/$ID/uningest

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X POST https://demo.dataverse.org/api/files/24/uningest

A curl example using a PERSISTENT_ID:

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_ID=doi:10.5072/FK2/AAA000

curl -H "X-Dataverse-key:$API_TOKEN" -X POST "$SERVER_URL/api/files/:persistentId/uningest?persistentId=$PERSISTENT_ID"

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X POST "https://demo.dataverse.org/api/files/:persistentId/uningest?persistentId=doi:10.5072/FK2/AAA000"

Reingest a File

Attempt to ingest an existing datafile as tabular data. This API can be used on a file that was not ingested as tabular back when it was uploaded. For example, a Stata v.14 file that was uploaded before ingest support for Stata 14 was added (in Dataverse v.4.9). It can also be used on a file that failed to ingest due to a bug in the ingest plugin that has since been fixed (hence the name “reingest”).

Note that this requires “superuser” credentials.

A curl example using an ID

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=24

curl -H "X-Dataverse-key:$API_TOKEN" -X POST $SERVER_URL/api/files/$ID/reingest

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X POST https://demo.dataverse.org/api/files/24/reingest

A curl example using a PERSISTENT_ID

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_ID=doi:10.5072/FK2/AAA000

curl -H "X-Dataverse-key:$API_TOKEN" -X POST $SERVER_URL/api/files/:persistentId/reingest?persistentId=$PERSISTENT_ID

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X POST "https://demo.dataverse.org/api/files/:persistentId/reingest?persistentId=doi:10.5072/FK2/AAA000"

Note: at present, the API cannot be used on a file that’s already successfully ingested as tabular.

Redetect File Type

Dataverse uses a variety of methods for determining file types (MIME types or content types) and these methods (listed below) are updated periodically. If you have files that have an unknown file type, you can have Dataverse attempt to redetect the file type.

When using the curl command below, you can pass dryRun=true if you don’t want any changes to be saved to the database. Change this to dryRun=false (or omit it) to save the change.

A curl example using an id

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=24

curl -H "X-Dataverse-key:$API_TOKEN" -X POST "$SERVER_URL/api/files/$ID/redetect?dryRun=true"

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X POST "https://demo.dataverse.org/api/files/24/redetect?dryRun=true"

A curl example using a pid

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_ID=doi:10.5072/FK2/AAA000

curl -H "X-Dataverse-key:$API_TOKEN" -X POST "$SERVER_URL/api/files/:persistentId/redetect?persistentId=$PERSISTENT_ID&dryRun=true"

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X POST "https://demo.dataverse.org/api/files/:persistentId/redetect?persistentId=doi:10.5072/FK2/AAA000&dryRun=true"

Currently the following methods are used to detect file types:

  • The file type detected by the browser (or sent via API).
  • JHOVE: http://jhove.openpreservation.org
  • As a last resort the file extension (e.g. ”.ipybn”) is used, defined in a file called MimeTypeDetectionByFileExtension.properties.

Replacing Files

Replace an existing file where ID is the database id of the file to replace or PERSISTENT_ID is the persistent id (DOI or Handle) of the file. Requires the file to be passed as well as a jsonString expressing the new metadata. Note that metadata such as description, directoryLabel (File Path) and tags are not carried over from the file being replaced.

A curl example using an ID

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=24

curl -H "X-Dataverse-key:$API_TOKEN" -X POST -F 'file=@file.extension' -F 'jsonData={json}' $SERVER_URL/api/files/$ID/replace

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -X POST -F 'file=@data.tsv' \
  -F 'jsonData={"description":"My description.","categories":["Data"],"forceReplace":false}' \
  https://demo.dataverse.org/api/files/24/replace

A curl example using a PERSISTENT_ID

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export PERSISTENT_ID=doi:10.5072/FK2/AAA000

curl -H "X-Dataverse-key:$API_TOKEN" -X POST -F 'file=@file.extension' -F 'jsonData={json}' \
  "$SERVER_URL/api/files/:persistentId/replace?persistentId=$PERSISTENT_ID"

The fully expanded example above (without environment variables) looks like this:

Note: The id returned in the json response is the id of the file metadata version.

Updating File Metadata

Updates the file metadata for an existing file where ID is the database id of the file to update or PERSISTENT_ID is the persistent id (DOI or Handle) of the file. Requires a jsonString expressing the new metadata. No metadata from the previous version of this file will be persisted, so if you want to update a specific field first get the json with the above command and alter the fields you want.

A curl example using an ID

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org

  "https://demo.dataverse.org/api/files/:persistentId/metadata?persistentId=doi:10.5072/FK2/AAA000"

Also note that dataFileTags are not versioned and changes to these will update the published version of the file.

Editing Variable Level Metadata

Updates variable level metadata using ddi xml FILE, where ID is file id.

A curl example using an ID

export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org

Datafile Integrity

Starting the release 4.10 the size of the saved original file (for an ingested tabular datafile) is stored in the database. The following API will retrieve and permanently store the sizes for any already existing saved originals:

export SERVER_URL=https://localhost

curl $SERVER_URL/api/admin/datafiles/integrity/fixmissingoriginalsizes

with limit parameter:

export SERVER_URL=https://localhost
export LIMIT=10

curl "$SERVER_URL/api/admin/datafiles/integrity/fixmissingoriginalsizes?limit=$LIMIT"

The fully expanded example above (without environment variables) looks like this:

curl https://localhost/api/admin/datafiles/integrity/fixmissingoriginalsizes"

with limit parameter:

curl https://localhost/api/admin/datafiles/integrity/fixmissingoriginalsizes?limit=10"

Note the optional “limit” parameter. Without it, the API will attempt to populate the sizes for all the saved originals that don’t have them in the database yet. Otherwise it will do so for the first N such datafiles.

By default, the admin API calls are blocked and can only be called from localhost. See more details in :BlockedApiEndpoints and :BlockedApiPolicy settings in Configuration.

Users Token Management

The following endpoints will allow users to manage their API tokens.

Find a Token’s Expiration Date

In order to obtain the expiration date of a token use:

curl -H X-Dataverse-key:$API_TOKEN -X GET $SERVER_URL/api/users/token

Recreate a Token

In order to obtain a new token use:

curl -H X-Dataverse-key:$API_TOKEN -X POST $SERVER_URL/api/users/token/recreate

Delete a Token

In order to delete a token use:

curl -H X-Dataverse-key:$API_TOKEN -X DELETE $SERVER_URL/api/users/token

Builtin Users

Builtin users are known as “Username/Email and Password” users in the Account Creation + Management of the User Guide. Dataverse stores a password (encrypted, of course) for these users, which differs from “remote” users such as Shibboleth or OAuth users where the password is stored elsewhere. See also Auth Modes: Local vs. Remote vs. Both section of Configuration in the Installation Guide. It’s a valid configuration of Dataverse to not use builtin users at all.

Create a Builtin User

For security reasons, builtin users cannot be created via API unless the team who runs the Dataverse installation has populated a database setting called BuiltinUsers.KEY, which is described under Securing Your Installation and Database Settings sections of Configuration in the Installation Guide. You will need to know the value of BuiltinUsers.KEY before you can proceed.

To create a builtin user via API, you must first construct a JSON document. You can download user-add.json or copy the text below as a starting point and edit as necessary.

{
  "firstName": "Lisa",
  "lastName": "Simpson",
  "userName": "lsimpson",
  "affiliation": "Springfield",
  "position": "Student",
  "email": "lsimpson@mailinator.com"
}

Place this user-add.json file in your current directory and run the following curl command, substituting variables as necessary. Note that both the password of the new user and the value of BuiltinUsers.KEY are passed as query parameters:

curl -d @user-add.json -H "Content-type:application/json" "$SERVER_URL/api/builtin-users?password=$NEWUSER_PASSWORD&key=$BUILTIN_USERS_KEY"

Optionally, you may use a third query parameter “sendEmailNotification=false” to explicitly disable sending an email notification to the new user.

Roles

Create a New Role in a Dataverse

Creates a new role in dataverse object whose Id is dataverseIdtf (that’s an id/alias):

POST http://$SERVER/api/roles?dvo=$dataverseIdtf&key=$apiKey

Show Role

GET http://$SERVER/api/roles/$id

Delete Role

Deletes the role with id:

DELETE http://$SERVER/api/roles/$id

Explicit Groups

Create New Explicit Group

Explicit groups list their members explicitly. These groups are defined in dataverses, which is why their API endpoint is under api/dataverses/$id/, where $id is the id of the dataverse.

Create a new explicit group under dataverse $id:

POST http://$server/api/dataverses/$id/groups

Data being POSTed is json-formatted description of the group:

{
 "description":"Describe the group here",
 "displayName":"Close Collaborators",
 "aliasInOwner":"ccs"
}

List Explicit Groups in a Dataverse

List explicit groups under dataverse $id:

GET http://$server/api/dataverses/$id/groups

PUT http://$server/api/dataverses/$dv/groups/$groupAlias

Delete Group from a Dataverse

Delete group $groupAlias under dataverse $dv:

DELETE http://$server/api/dataverses/$dv/groups/$groupAlias

Add Multiple Role Assignees to an Explicit Group

Bulk add role assignees to an explicit group. The request body is a JSON array of role assignee identifiers, such as @admin, &ip/localhosts or :authenticated-users:

POST http://$server/api/dataverses/$dv/groups/$groupAlias/roleAssignees

Add a Role Assignee to an Explicit Group

Add a single role assignee to a group. Request body is ignored:

PUT http://$server/api/dataverses/$dv/groups/$groupAlias/roleAssignees/$roleAssigneeIdentifier

Remove a Role Assignee from an Explicit Group

Remove a single role assignee from an explicit group:

DELETE http://$server/api/dataverses/$dv/groups/$groupAlias/roleAssignees/$roleAssigneeIdentifier

Admin

This is the administrative part of the API. For security reasons, it is absolutely essential that you block it before allowing public access to a Dataverse installation. Blocking can be done using settings. See the post-install-api-block.sh script in the scripts/api folder for details. See Blocking API Endpoints in Securing Your Installation section of the Configuration page of the Installation Guide.

List All Database Settings

List all settings:

GET http://$SERVER/api/admin/settings

Configure Database Setting

Sets setting name to the body of the request:

PUT http://$SERVER/api/admin/settings/$name

Get Single Database Setting

Get the setting under name:

GET http://$SERVER/api/admin/settings/$name

Delete Database Setting

Delete the setting under name:

DELETE http://$SERVER/api/admin/settings/$name

Manage Banner Messages

Communications to users can be handled via banner messages that are displayed at the top of all pages within your Dataverse installation. Two types of banners can be configured:

  • A banner message where dismissibleByUser is set to false will be displayed to anyone viewing the application. These messages will be dismissible for a given session but will be displayed in any subsequent session until they are deleted by the Admin. This type of banner message is useful for situations such as upcoming maintenance windows and other downtime.
  • A banner message where dismissibleByUser is set to true is intended to be used in situations where the Admin wants to make sure that all logged in users see a certain notification. These banner messages will only be displayed to users when they are logged in and can be dismissed by the logged in user. Once they have been dismissed by a user, that user will not see the message again. This type of banner message is useful for situations where a message needs to communicated once, such as a minor terms of use update or an update about a new workflow in your Dataverse installation.

Note that HTML can be included in banner messages.

Add a Banner Message:

curl -H "Content-type:application/json" -X POST http://$SERVER/api/admin/bannerMessage --upload-file messages.json

Where messages.json looks like this:

{
  "dismissibleByUser": "true",
  "messageTexts": [
  {
    "lang": "en",
    "message": "Dismissible Banner Message added via API"
  },
  {
    "lang": "fr",
    "message": "Message de bannière ajouté via l'API"
  }
  ]
}

Get a list of active Banner Messages:

curl  -X GET http://$SERVER/api/admin/bannerMessage

Delete a Banner Message by its id:

curl  -X DELETE http://$SERVER/api/admin/bannerMessage/$id

Deactivate a Banner Message by its id (allows you to hide a message while retaining information about which users have dismissed the banner):

curl  -X PUT http://$SERVER/api/admin/bannerMessage/$id/deactivate

List Authentication Provider Factories

List the authentication provider factories. The alias field of these is used while configuring the providers themselves.

GET http://$SERVER/api/admin/authenticationProviderFactories

List Authentication Providers

List all the authentication providers in the system (both enabled and disabled):

GET http://$SERVER/api/admin/authenticationProviders

Add Authentication Provider

Add new authentication provider. The POST data is in JSON format, similar to the JSON retrieved from this command’s GET counterpart.

POST http://$SERVER/api/admin/authenticationProviders

Show Authentication Provider

Show data about an authentication provider:

GET http://$SERVER/api/admin/authenticationProviders/$id

Enable or Disable an Authentication Provider

Enable or disable an authentication provider (denoted by id):

PUT http://$SERVER/api/admin/authenticationProviders/$id/enabled

Note

The former endpoint, ending with :enabled (that is, with a colon), is still supported, but deprecated.

Check If an Authentication Provider is Enabled

Check whether an authentication proider is enabled:

GET http://$SERVER/api/admin/authenticationProviders/$id/enabled

The body of the request should be either true or false. Content type has to be application/json, like so:

curl -H "Content-type: application/json"  -X POST -d"false" http://localhost:8080/api/admin/authenticationProviders/echo-dignified/:enabled

Delete an Authentication Provider

Deletes an authentication provider from the system. The command succeeds even if there is no such provider, as the postcondition holds: there is no provider by that id after the command returns.

DELETE http://$SERVER/api/admin/authenticationProviders/$id/

List Global Roles

List all global roles in the system.

GET http://$SERVER/api/admin/roles

Create Global Role

Creates a global role in the Dataverse installation. The data POSTed are assumed to be a role JSON.

POST http://$SERVER/api/admin/roles

List Users

List users with the options to search and “page” through results. Only accessible to superusers. Optional parameters:

  • searchTerm A string that matches the beginning of a user identifier, first name, last name or email address.
  • itemsPerPage The number of detailed results to return. The default is 25. This number has no limit. e.g. You could set it to 1000 to return 1,000 results
  • selectedPage The page of results to return. The default is 1.
  • sortKey A string that represents a field that is used for sorting the results. Possible values are “id”, “useridentifier” (username), “lastname” (last name), “firstname” (first name), “email” (email address), “affiliation” (affiliation), “superuser” (flag that denotes if the user is an administrator of the site), “position”, “createdtime” (created time), “lastlogintime” (last login time), “lastapiusetime” (last API use time). The default is “useridentifier”.
export API_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export SERVER_URL=https://demo.dataverse.org
export ID=24

curl -H "X-Dataverse-key:$API_TOKEN" $SERVER_URL/api/admin/list-users

# sort by createdtime (the creation time of the account)
curl -H "X-Dataverse-key:$API_TOKEN" "$SERVER_URL/api/admin/list-users?sortKey=createdtime"

The fully expanded example above (without environment variables) looks like this:

curl -H "X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" https://demo.dataverse.org/api/admin/list-users

# sort by createdtime (the creation time of the account)
curl -H "X-Dataverse-key:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" "https://demo.dataverse.org/api/admin/list-users?sortKey=createdtime"

Sample output appears below.

  • When multiple pages of results exist, the selectedPage parameters may be specified.
  • Note, the resulting pagination section includes pageCount, previousPageNumber, nextPageNumber, and other variables that may be used to re-create the UI.

Sample output using “dataverseAdmin” as the identifier:

{
  "authenticationProviderId": "builtin",
  "persistentUserId": "dataverseAdmin",
  "position": "Admin",
  "id": 1,
  "identifier": "@dataverseAdmin",
  "displayName": "Dataverse Admin",
  "firstName": "Dataverse",
  "lastName": "Admin",
  "email": "dataverse@mailinator.com",
  "superuser": true,
  "affiliation": "Dataverse.org"
}

Create an Authenticated User

Create an authenticatedUser:

POST http://$SERVER/api/admin/authenticatedUsers

POSTed JSON example:

{
  "authenticationProviderId": "orcid",
  "persistentUserId": "0000-0002-3283-0661",
  "identifier": "@pete",
  "firstName": "Pete K.",
  "lastName": "Dataversky",
  "email": "pete@mailinator.com"
}

Merge User Accounts

If a user has created multiple accounts and has been performed actions under both accounts that need to be preserved, these accounts can be combined. One account can be merged into another account and all data associated with both accounts will be combined in the surviving account. Only accessible to superusers.:

POST https://$SERVER/api/users/$toMergeIdentifier/mergeIntoUser/$continuingIdentifier

Example: curl -H "X-Dataverse-key: $API_TOKEN" -X POST http://demo.dataverse.org/api/users/jsmith2/mergeIntoUser/jsmith

This action moves account data from jsmith2 into the account jsmith and deletes the account of jsmith2.

Change User Identifier

Changes identifier for user in AuthenticatedUser, BuiltinUser, AuthenticatedUserLookup & RoleAssignment. Allows them to log in with the new identifier. Only accessible to superusers.:

POST http://$SERVER/api/users/$oldIdentifier/changeIdentifier/$newIdentifier

Example: curl -H "X-Dataverse-key: $API_TOKEN" -X POST  https://demo.dataverse.org/api/users/johnsmith/changeIdentifier/jsmith

This action changes the identifier of user johnsmith to jsmith.

Make User a SuperUser

Toggles superuser mode on the AuthenticatedUser whose identifier (without the @ sign) is passed.

POST http://$SERVER/api/admin/superuser/$identifier

Delete a User

Deletes an AuthenticatedUser whose identifier (without the @ sign) is passed.

DELETE http://$SERVER/api/admin/authenticatedUsers/$identifier

Deletes an AuthenticatedUser whose id is passed.

DELETE http://$SERVER/api/admin/authenticatedUsers/id/$id

Note: If the user has performed certain actions such as creating or contributing to a Dataset or downloading a file they cannot be deleted.

List Role Assignments of a Role Assignee

List all role assignments of a role assignee (i.e. a user or a group):

GET http://$SERVER/api/admin/assignments/assignees/$identifier

Note that identifier can contain slashes (e.g. &ip/localhost-users).

List Permissions a User Has on a Dataverse or Dataset

List permissions a user (based on API Token used) has on a dataverse or dataset:

GET http://$SERVER/api/admin/permissions/$identifier

The $identifier can be a dataverse alias or database id or a dataset persistent ID or database id.

Show Role Assignee

List a role assignee (i.e. a user or a group):

GET http://$SERVER/api/admin/assignee/$identifier

The $identifier should start with an @ if it’s a user. Groups start with &. “Built in” users and groups start with :. Private URL users start with #.

Dataset Integrity

Recalculate the UNF value of a dataset version, if it’s missing, by supplying the dataset version database id:

POST http://$SERVER/api/admin/datasets/integrity/{datasetVersionId}/fixmissingunf

Datafile Integrity

Recalculate the check sum value value of a datafile, by supplying the file’s database id and an algorithm (Valid values for $ALGORITHM include MD5, SHA-1, SHA-256, and SHA-512):

curl -H X-Dataverse-key:$API_TOKEN -X POST $SERVER_URL/api/admin/computeDataFileHashValue/{fileId}/algorithm/$ALGORITHM

Validate an existing check sum value against one newly calculated from the saved file:

curl -H X-Dataverse-key:$API_TOKEN -X POST $SERVER_URL/api/admin/validateDataFileHashValue/{fileId}

Physical Files Validation in a Dataset

The following validates all the physical files in the dataset spcified, by recalculating the checksums and comparing them against the values saved in the database:

$SERVER_URL/api/admin/validate/dataset/files/{datasetId}

It will report the specific files that have failed the validation. For example:

curl http://localhost:8080/api/admin/validate/dataset/files/:persistentId/?persistentId=doi:10.5072/FK2/XXXXX
  {"dataFiles": [
               {"datafileId":2658,"storageIdentifier":"file://123-aaa","status":"valid"},
               {"datafileId":2659,"storageIdentifier":"file://123-bbb","status":"invalid","errorMessage":"Checksum mismatch for datafile id 2669"},
               {"datafileId":2659,"storageIdentifier":"file://123-ccc","status":"valid"}
               ]
   }

These are only available to super users.

Dataset Validation

Validate the dataset and its components (DatasetVersion, FileMetadatas, etc.) for constraint violations:

curl $SERVER_URL/api/admin/validate/dataset/{datasetId}

if validation fails, will report the specific database entity and the offending value. For example:

{"status":"OK","data":{"entityClassDatabaseTableRowId":"[DatasetVersion id:73]","field":"archiveNote","invalidValue":"random text, not a url"}}

If the optional argument variables=true is specified, the API will also validate the metadata associated with any tabular data files found in the dataset specified. (For example: an invalid or empty variable name).

Validate all the datasets in the Dataverse, report any constraint violations found:

curl $SERVER_URL/api/admin/validate/datasets

If the optional argument variables=true is specified, the API will also validate the metadata associated with any tabular data files. (For example: an invalid or empty variable name). Note that validating all the tabular metadata may significantly increase the run time of the full validation pass.

This API streams its output in real time, i.e. it will start producing the output immediately and will be reporting on the progress as it validates one dataset at a time. For example:

{"datasets": [
             {"datasetId":27,"status":"valid"},
             {"datasetId":29,"status":"valid"},
             {"datasetId":31,"status":"valid"},
             {"datasetId":33,"status":"valid"},
             {"datasetId":35,"status":"valid"},
             {"datasetId":41,"status":"invalid","entityClassDatabaseTableRowId":"[DatasetVersion id:73]","field":"archiveNote","invalidValue":"random text, not a url"},
             {"datasetId":57,"status":"valid"}
             ]
 }

Note that if you are attempting to validate a very large number of datasets in your Dataverse, this API may time out - subject to the timeout limit set in your app server configuration. If this is a production Dataverse instance serving large amounts of data, you most likely have that timeout set to some high value already. But if you need to increase it, it can be done with the asadmin command. For example:

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

Workflows

List all available workflows in the system:

GET http://$SERVER/api/admin/workflows

Get details of a workflow with a given id:

GET http://$SERVER/api/admin/workflows/$id

Add a new workflow. Request body specifies the workflow properties and steps in JSON format. Sample json files are available at scripts/api/data/workflows/:

POST http://$SERVER/api/admin/workflows

Delete a workflow with a specific id:

DELETE http://$SERVER/api/admin/workflows/$id

Warning

If the workflow designated by $id is a default workflow, a 403 FORBIDDEN response will be returned, and the deletion will be canceled.

List the default workflow for each trigger type:

GET http://$SERVER/api/admin/workflows/default/

Set the default workflow for a given trigger. This workflow is run when a dataset is published. The body of the PUT request is the id of the workflow. Trigger types are PrePublishDataset, PostPublishDataset:

PUT http://$SERVER/api/admin/workflows/default/$triggerType

Get the default workflow for triggerType. Returns a JSON representation of the workflow, if present, or 404 NOT FOUND.

GET http://$SERVER/api/admin/workflows/default/$triggerType

Unset the default workflow for triggerType. After this call, dataset releases are done with no workflow.

DELETE http://$SERVER/api/admin/workflows/default/$triggerType

Set the whitelist of IP addresses separated by a semicolon (;) allowed to resume workflows. Request body is a list of IP addresses allowed to send “resume workflow” messages to this Dataverse instance:

PUT http://$SERVER/api/admin/workflows/ip-whitelist

Get the whitelist of IP addresses allowed to resume workflows:

GET http://$SERVER/api/admin/workflows/ip-whitelist

Restore the whitelist of IP addresses allowed to resume workflows to default (localhost only):

DELETE http://$SERVER/api/admin/workflows/ip-whitelist

Metrics

Clear all cached metric results:

DELETE http://$SERVER/api/admin/clearMetricsCache

Clear a specific metric cache. Currently this must match the name of the row in the table, which is named metricName*_*metricYYYYMM (or just metricName if there is no date range for the metric). For example dataversesToMonth_2018-05:

DELETE http://$SERVER/api/admin/clearMetricsCache/$metricDbName

Inherit Dataverse Role Assignments

Recursively applies the role assignments of the specified dataverse, for the roles specified by the :InheritParentRoleAssignments setting, to all dataverses contained within it:

GET http://$SERVER/api/admin/dataverse/{dataverse alias}/addRoleAssignmentsToChildren

Note: setting :InheritParentRoleAssignments will automatically trigger inheritance of the parent dataverse’s role assignments for a newly created dataverse. Hence this API call is intended as a way to update existing child dataverses or to update children after a change in role assignments has been made on a parent dataverse.
