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.
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.
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.

Retrieving items within a user set
Retrieves a limit number of items contained within a specific user set.

The number of items to retrieve, maximum is 100, defaults to 10.
