An RDF source is a resource that may be said to have a state that can change over time. A snapshot of the state can be expressed as an RDF graph So a RDF source may return *multiple* RDF graphs, i.e., a dataset but at the same time it is possible to express a snapshot as a *single* RDF *graph*. Thus, we should either define something like a "RDF graph source" or say that a snapshot of a RDF source can be expressed as a RDF dataset. If we are going to use this reuse terminology, I think we should also name the classes accordingly. Something like rdf:RdfGraphSource and potentially also something like rdf:TripleSource or just rdf:RdfSource. -- Markus Lanthaler @markuslanthaler
