You would need relations from Agents to graphs.

:joe a foaf:Person;
      g:said :g .

:g a :Graph;
    = { :jane a :Beauty . }

Or you could have a relation from Agents to resources, where the  
resources is a document that has a graph as above.

:joe a foaf:Person;
      doc:said <http://joe.com/rss/item2> .

<http://joe.com/rss/item2> log:semantics { :jane a :Beauty . } .

It would be nice to have standards URIs for the most useful  
propositional attitudes. I think you may find some in the cwm cvs  
source tree.
