[OAI-implementers] repositoryIdentifier

[David Loy]

Sorry to bug the list on something like this but what exactly does the 
repositoryIdentifier represent?

Is it an organizational id (e.g. cdlib.org) or is it an identifier specific 
to the oai service (e.g. oai.cdlib.org)?

Does the id have any  special functional meaning - used in some list of 
providers etc.

Is there  a document (etc.) that describes  the semantics of these elements 
- so I won't have to bug the list?

Thanks!
