Re: PROV-ISSUE-233 (paq-dm-and-accounts?): If not in DM, should there be some form of account support in the paq? [Accessing and Querying Provenance]

Hi Graham,
If it's the role of provenance-uri, fine, but we have to make sure that 
the protocol
can work with provenance-uris that are not dereferenceable.
For instance, we should be able to support "names" of bundles that are a 
UUID uri.
Thanks,
Luc
