Retrieve Identifiers for a Node

Retrieve a list of all identifiers (such as DOIs or ARKs) associated with the specified node. Identifiers are unique strings that reference the node in external systems. These can include persistent identifiers such as DOIs (Digital Object Identifiers) or ARKs (Archival Resource Keys).

Response Structure

The response returns a JSON object containing the following top-level keys:

• data: An array of identifier resources.
• links: Pagination links (if applicable).

Each item in the data array is a distinct identifier object, containing details such as the identifier category (e.g., doi, ark), its value, and links to the associated node.

Filtering

You may filter the returned identifiers by category using the filter[category] query parameter. Example: Supported filter categories include:

• doi - Digital Object Identifier
• ark - Archival Resource Key
