I got the impression that something was going to be proposed, but it seemed vague . . . is there something being proposed? On the 303 stuff: I don't understand the problem. RDF can talk about various things, not just web pages: RDF uses general URIs, which could be URLs, URNs, or whatever else is invented. If you don't want to make statements about a web page, you don't use an http URL. What is the need for using 303 responses? And I don't understand the JSON comparison. Sure, RDF in XML is dismal, but RDF in Turtle is OK. The core, real, RDF is just URI triples -- subject, predicate, object -- it is already very simple, elegant, and powerful. How does JSON help? I do like the idea of RDF/data-web/GGG uses and applications, but I can't figure out what this article is really trying to say.
