Fedora 3.0 API
DOMS metadata objects will be stored in Fedora-commons 3.0.
The API is documented here: http://www.fedora-commons.org/documentation/3.0/userdocs/index.html#webservices
The following restrictions apply:
The possibilities "PurgeDatastream" and "PurgeObject" are not allowed. Instead change the state to deleted
- setDatastreamVersionable is disallowed. The internal datastreams are always versioned.
- Do not use getNextPID, instead use the method provided from DOMS
All ingested objects, and all updates, must lead to valid objects, as defined by the data model. The exception is that objects marked as "draft" or "intermediate" in the datamodel are always considered valid.
Making a call to any API method that changes the object to a state not valid as defined by the datamodel will fail. Any call to a state-changing API-call where the object is not first set to intermediate state will fail.
Examples
Saving seven new interrelated objects to DOMS
Since the datamodel may require that all seven objects are correctly ingested and interrelated before they are valid, ingest all seven objects in intermediate state, and then publish them
- Call the method for generating DOMS PIDs seven times
- Generate 7 FoxML objects, each with the administrative state set to "intermediate"
Call API-M ingest seven times
Call API-M modifyDatastreamByValue 7 times to update the state to "published"
Updating fields and references for 8 interrelated objects
To make sure that the changes don't interfere with validity, first set the state to intermediate, then update state to published after modifications.
Call API-M modifyDatastreamByValue 8 times to update the administrative state to "intermediate"
Update datastreams and relations as needed to make the changes using addRelationsship/addDatastream/purgeRelationship/modifyDatastreamByValue/setDatastreamState
Call API-M modifyDatastreamByValue 8 times to update the administrative state to "published"
Usage of Fedora API-M and API-A
The following describes those methods of the Fedora API-M and API-A that may be called by the GUI.
Descriptions in the following were copied (in part) from the Fedora documentation at http://www.fedora-commons.org/confluence/display/FCR30/API-M and http://www.fedora-commons.org/confluence/display/FCR30/API-A.
