I am raising this issue against the paq, but really, this is a paq/dm issue.

At F2F2, we have decided to simplify PROV-DM, by dropping the notion of AccountRecord from the data model. It should simplify the DM since we no longer have this notion of scope, which was challenging.

I anticipate the prov-DM will now say that it assumes the existence of a mechanism (outside the PROV-DM) by which bundles of records/assertions can be given a name. 

The PR0V-DM used to offer a RecordContainer and the ability to package up accounts in such containers, such that multiple accounts could be returned when retrieving provenance for an entity-uri. A client was then able to sift through the container, and find whatever it was looking for, possibly multiple entity records for entity-uri in various accounts.  All that was possible without having to discuss accounts in the PAQ document.

Now, this facility has gone.  

So the question is: how do we find what is being said about a given entity-uris in multiple "bundles/accounts"?

PS. At F2F2 meeting, we discuss the requirement to support the provenance of provenance. I think we also have to record multiple accounts of what happened to an entity (even by a same provider!).
