- Define a generic method (or set of methods) for applying partial changes to datastreams.
- Implement it for RELS-EXT and RELS-INT (RDF-based) so that additions and deletions to those datastreams can be made via SPARQL update.
Example:
- HTTP Verb: PUT
- URL: /objects/{pid}/fedora-system:/updateDatastream?dsID={dsID}&type=sparql-update
- Body: A SPARQL/Update document (UTF-8?) to apply to the datastream
- Successful response:** Code: 201
- Location header: URL to datastream
- Failed response:** If datastream doesn't exist: TBD
- If input document is malformed: TBD
