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--
