Finding media records from a given collectionobject record

The relations service provides the mechanism to find related records of a given type. With a known collectionobject csid, the API call would be

http://cspacetest.collectionspace.org:8180/cspace-services/relations?sbj={{csid}}&objType=MediaTenant42

The objType value is the Media document type for the unique MMI tenant, MediaTenant42.

If only one media record is displayed then it should be considered to be the primary media record.

REST API calls

An API call would follow the following format

Media record information

http://cspacetest.collectionspace.org:8180/cspace-services/media/{{csid}}

Blob content for Media record

http://cspacetest.collectionspace.org:8180/cspace-services/media/{{csid}}/blob

Actual image data (original image image)

http://cspacetest.collectionspace.org:8180/cspace-services/media/{{csid}}/blob/content

Derivative formats

http://cspacetest.collectionspace.org:8180/cspace-services/media/{{csid}}/blob/derivatives/{{Medium||Original||Thumbnail||OriginalJpeg}}/content

Currently, MMI is using small quality and size jpg files as original media content, but larger quality and larger file sized images could be used in the future.
Unless otherwise noted, Medium sized derivatives should be used for the browser.

Get referenced authority records

Append authorityrefs to the API URL for a collectionobject record to get a list of referenced authority records': sourceField, itemDisplayName and refName (in short ID format).

An example API call for authorityrefs for a given media record
