RDF WG Graph Use Cases

Hi all,

The RDF WG's Graph Task Force keeps a list of use cases regarding graphs at:
  http://www.w3.org/2011/rdf-wg/wiki/TF-Graphs-UC

Perhaps someone from the Provenance WG can tell us which, if any, of those use cases apply to or are under consideration by the Provenance WG?  Thanks.

Regards,
Dave
