Re: [ietf-types] Q's regarding development of +json media types

I don't think it makes sense to describe JSON serializations of Notation 3 or N-Triples, as these are themselves just serializations of RDF. Perhaps what you're describing is two different JSON serializations of RDF, one which is more closely related to Notation-3 and the other N-Triples. Although, note that Notation-3 is, itself, a super-set of N-Triples (as is Turtle [1]), so is there really a requirement for two different serializations, or isn't it up to the author to chose a particular syntax using different capabilities of the format.

Also, note that Notation-3 is more than a syntax, as it includes behavior as well as representation, which is one reason Turtle was created. A purely syntactic version of Notation-3 is n3-rdf [2], which is a relatively small super-set of Turtle itself.

Does this relate, in anyway to JSON-LD [3], which is also an RDF serialization in JSON?

Perhaps application/rdf+json would be an appropriate mime-type.
