Fedora 3.0 API
DOMS metadata objects will be stored in Fedora-commons 3.0.
The API is documented here, as far as it goes: http://www.fedora-commons.org/documentation/3.0/userdocs/index.html#webservices
The API to Fedora is directly exported as the primary API to DOMS. We have restricted a few methods, and have some conventions about certain other should be used.
The following methods are restricted
[:/Managment#PurgeDatastream: apiM.PurgeDatastream] and[:/Managment#PurgeObject: apiM.PurgeObject] are not allowed. Instead use [:Fedora_3.0_API/Managment#modifyDatastream: apiM.modifyDatastream] and [:Fedora_3.0_API/Managment#modifyObject: apiM.modifyObject] to change the state to "D" (deleted).
- [:/Managment#setDatastreamVersionable: apiM.setDatastreamVersionable] is disallowed. The internal datastreams are always versioned.
- Do not use getNextPID, instead use the method provided from DOMS
Objects that are marked as "published" (see FedoraTransactionsReplacement) cannot be changed. Any API calls that attempt to change them will fail. There will be made a service to atomically change the state of objects. TODO!!!
The Fedora API is described in the the pages below.
- [:/Access: The public Access API] - Everybody can use this, this is the primary way for external applications to query the repository.
- [:/Managment: The protected Managment API] - Only authenticated administrators, such as users of the GUI, can use this.
- [:/RIsearch: The Resource Index API] - The interface to the Fedora triple store.
