  description: >-
    Public read-only DSpace 6 legacy REST API for Edinburgh DataShare, the
    University of Edinburgh's open-access research-data repository. Allows
    programmatic querying of communities, collections, items, bitstreams and
    the metadata/schema registry. Responses are JSON. This specification was
    reconstructed from the live API index at https://datashare.ed.ac.uk/rest
    and verified against live responses; only the documented public GET
    endpoints are described here.
