rdf-prov,

In preparation for the RDF WG F2F this week, I wanted to provide some discussion on using named graphs to address some provenance modeling.

I have updated http://www.w3.org/2011/prov/wiki/Using_named_graphs_to_model_Accounts to reflect some feedback and extend the discussion on named graphs.

In particular, I discuss:

* reuse of the SPARQL Service Description vocabulary to describe named graphs.
* Meta Named Graph pairs, 
* a simple application of these to create Cache Graphs
* the importance of modeling the "location" of a graph to disambiguate many graphs with the same name.

These components are needed to model PROV's notion of Accounts, which permit different agents to assert different views of the same "event" (i.e., ProcessExecution). I hope to wrap up all of this into a final proposal by the end of the week.

Any suggestions or comments appreciated.

Regards,
Tim Lebo
