If one wants to deal with multiple and/or different RDFGraphs one needs an Identifier that says which kind of Graph one has to access. So one ends up in a Quadruple Store where one also has an Identifier everywhere that states that a certain Triplebelongs to a specific Graph. In such one has some provenance information that is given in a Quadruple Store.
