The User Set API allows users to create and maintain their own collection of items (sets) that are available in Europeana. Besides creating sets, users can also search for sets that were created by other users and are available for public viewing. This API supports the gallery functionality that is available in the Europeana website for logged-in users.

Retrieval

Methods for accessing either the metadata of a user set or the metadata of the items that are part of the user set. Considering that the number of items that are part of the user may be relatively high, it was decided to separate the user set metadata from the item metadata retrieval and to offer a paginated approach to accessing the information about the items that are part of the user set.

Retrieving user set metadata

Retrieves all metadata available for a specific user set. This includes all descriptive metadata but leaves out the contents of the set.

Request

Code Block
https://api.europeana.eu/set/[IDENTIFIER] Accept: [ACCEPT]

Code Block
https://api.europeana.eu/set/[IDENTIFIER].[FORMAT]

Parameter	Location	Description
IDENTIFIER	path	The local identifier of the user set.
ACCEPT	header	Indicates the preferred format via which the user set is to be represented if the format is accepted by the service. Only JSON-LD is supported.
FORMAT	path	Convenience method where the format is indicated as a path parameter instead of via the Accept header.

Response

On success, the method returns a HTTP 200 with the metadata of the user set.

Field	Datatype	Description
User Set
@context	String (URL)	The JSON-LD context
id	String (URI)	The unique identifier of the user set

type	String	The type of the resource. Always set to "Organization".
name	String	The name of the project that contributed the set.

Retrieving items within a user set

Retrieves a limit number of items contained within a specific user set. This method is used to traverse through the complete list of items within the user set by requesting each page of items at a time. Use the 'page' and 'pageSize' parameters to navigate or follow the links in the 'next' or 'prev' properties to navigate respectively to the next or previous page.

Request

https://api.europeana.eu/set/[IDENTIFIER]?page=[PAGE] Accept: [ACCEPT]

Parameter	Location	Description
IDENTIFIER	path	The local identifier of the user set.
page	query	The number of the page (defaults to 1).
pageSize	query	The number of items to retrieve, maximum is 100, defaults to 10.

Two profiles are available “standard“ (default) and “itemDescriptions“. standard: Presents only the identifiers of the items that are part of the page. itemDescriptions: Presents the metadata of the item as obtained from the Search API.
ACCEPT	header	Indicates the preferred format via which the user set is to be represented if the format is accepted by the service. Only JSON-LD is supported.

Discovery

Methods for searching for items that are part of a user set or to search across all user sets that are available in Europeana.

Search for items within a user set

Search for items contained within a user set based on a given selection criteria. This method is paginated similar to the listing method. Use the 'page' and 'pageSize' parameters to navigate or follow the links in the 'next' or 'prev' properties to navigate, respectively, to the next or previous page.

Fields available for search:
