Description

Clients may need a mechanism to generate GUIDs before they build various types of documents in which the GUIDs are embedded, and they need to be sure these GUIDs will not be used before they are inserted. Add to the CN architecture a new method:

reserveIdentifier(scope?, format?) -> GUID
format = UUID, DOI, Handle, etc

Be sure that only the client reserving the GUID can use it after it has been reserved (which might be hard).

History

#1 Updated by Matthew Jones almost 15 years ago

I defined the reserveId() format for the CN service and added it to CN_APIs.txt. Clients that reserve GUIDs must use the existing session to utilize the GUID, which could have potential ramifications on denial of service and other issues we should consider. The alternative is to reserve it from any session from the logged-in user. The concept of a reserved ID can't be tracked without identifying who is reserving it somehow.

Need to modify CN and MN crud ops to throw an exception if someone tries to use a reserved API who didn't reserve it.

#20 Updated by Ben Leinfelder about 13 years ago

Current docs indicate a separate method for generating IDs: http://mule1.dataone.org/ArchitectureDocs-current/apis/CN_APIs.html#CNCore.generateIdentifier
I think minting DOIs was considered against EZID's best interests -- MNs should probably be responsible for this. But it seems we keep going back and forth on this.
