Post-teleconference... it could help if the wiki page had links to the RDF graph 
terminology you're using.  I'm way behind the RDF WG discussions.

I think my difficulties here stem substantially from the assertion being part of 
the account, rather than something that is done to an account.

Example: how do you handle this:

Alice asserts an account with some set of RDF triples at time t1.

Bob asserts an account with the same set of RDF triples at time t2.

Are these the same account?  If so, who asserted it, and when?
