However if I understand correctly, you were talking about something else e.g. about generating URIs for each file which will have to be unique, permanent and system independent. That implies additional maintenance costs for the repository.

Handles for items are generated using NOID on pre-ingest stage and are registered when item is ingested (we modified your handle server patch a bit).Most of our items have a rather complex structure and might include thousands of files in various formats which come from different sources. If we would have to support URIs on file level it would mean additional workflow steps and a more complicated pre-ingest process. On the other hand, it will not give us any additional functionality because our repository services are based on item not on file level. I don't think it's necessarily a bad idea, but I think it can have some serious consequences which might be bad for us. The decision on what level to support URIs determines, at least to some extent, what is the basic element in a repository. It's rather important decision, which might impact the repository architecture as a whole. I am concerned that if we (at NYU) do not support individual file's URIs while most other Dspace repositories do, then we might have problems with data compatibility and, in the long run, even with Dspace version upgrades.
