Read information object endpoint

GET /api/informationobjects/<slug>

This endpoint will obtain all information object data available for a particular archival description in fields that map to the ISAD template, including related PREMIS rights statements and digital object metadata


If you are using another descriptive standard as your default descriptive template, it is possible that not all data will be available in the endpoints response for a particular resource. For example the RAD template contains many custom note fields that do not have equivalents in the ISAD template.

To be able to query the endpoint, you will need to know the slug of the information object (aka archival description) you are trying to read. Note that the slug is include in the Browse information objects endpoint response, so you could use it to determine the slug of a particular description if needed.

Example request

GET /api/informationobjects/test-description HTTP/1.1

HTTP/1.1 200 OK
