Re: Section 4: LDPR/non-LDPR formal definitions

Kingsley,

RDF based Linked Data != RDF, you're right. Instead, RDF based Linked
Data = RDF wrapped in REST. I can prove this to you by showing source
code that takes Jena RDF API objects, wraps them with JAX-RS REST
code, and serves Linked Data.

That code has no problems working with generic RDF media types like
text/turtle, and I don't see why other Linked Data systems should have
a problem with that. Why invent new media types if the existing ones
just work? Media types are largely orthogonal to the LDP spec, which
should specify RDF state change over HTTP.
