I think it would be a good idea if this WG published a Note as well that talks about what we've changed and why. It should give use cases for every change. This was mentioned at the F2F.

Some new features will be added to the RDF package in order to address shortcomings of previous features. This will require explanation. For example, why add multigraphs when we already have reification? Why add Turtle when we already have RDF/XML and RDFa and N-Triples? Why add Skolemization when we already have blank nodes and URIs? The Note will probably need some text that contrasts each pair and highlights what each one is good for.

Such a Note might be a good place to also give guidance in other areas where RDF offers multiple features that seem to do the same thing. Like when to choose rdf:Seq and when to choose rdf:List?

The normative specs can contain links to that note.

Best,
Richard
