Hi,
I am currently adding support for efficient storage and retrieval of 
reifications to our triple-store Parliament.
I am currently concerned about how the implementation will handle 
partial reifications, i.e,:
ex:Stmt1 a rdf:Statement;
 rdf:subject ex:A;
 rdf:predicate ex:B .
and how it will handle overspecified reifications:
ex:Stmt1 a rdf:Statement;
 rdf:subject ex:A;
 rdf:predicate ex:B ;
 rdf:object ex:C ;
 rdf:object ex:D .
The RDF specification does not seem to say whether this is a valid use 
of the reification vocabulary.
Thus I am wondering whether A) this is considered valid RDF, and B) if 
there any reasonable use cases for these constructs.
I appreciate any input you might have.
Thanks,
--Dave--
