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.
