I think the best way of saying it is: it can be used as an RDF serialization, although applications may use it directly, too, without referring to RDF.

The answer is that this is a bit hidden in the document though, when reading it, the conversion is fairly clear. But I agree is it not explicit. Manu, it may be worth having a separate section that makes that mapping absolutely explicit and formal.

I think that if we get the previous issue done, that answers this question, too.

B.t.w., just for the fun of it: the RDFa 1.1 distiller http://www.w3.org/2012/pyRdfa/ already has a JSON-LD serialization option (alongside RDF/XML and turtle).
