RDF Assertions for HTTP Status Codes

This section proposes a set of RDF assertions corresponding to various HTTP response codes defined in RFC2616. It attempts to answer the question: "When a client receives a response from an HTTP server in response to a request, what is that server saying (in RDF) about the associated resource?" On 17-Nov-2009 we agree to focus on the following codes: 200, 201, 204 (lower priority), 205 (very low priority), 206 (low priority), 300, 301, 302, 303, 304, 307, 400, 404, 409, 410, 500.

We may want to cover this at more than one level of granularity.  For example, we might provide one set of rules that includes the server in the model and another simpler set that ignores the server. -- DBooth

Did we include this one by accident?  I don't think we need to cover it.  -- DBooth
