Reminds me of the pattern Edd Dumbill used in FOAFBot to store provenance in Redland before it acquired the native support he describes in http://www-128.ibm.com/developerworks/library/x-rdfprov.html For each triple ?s ?p ?o, he asserted ?s ?p2 ?o instead, and used ?p2 as a focal point for associating the statement occurance with provenance info. I forget whether ?p2 was explictly made a subproperty of ?p, but it could well have been.
