[HTTP-in-RDF] Revised simplified approach

Hi group,

based on the "simplified" approach presented in 
<http://lists.w3.org/Archives/Public/public-wai-ert/2007May/0024.html> 
and some discussion afterwards, here is a revision 
(HTTP-in-RDF_new_approach.txt).

There are "literal" properties for the Request's method (methodName), 
the Response's status code (statusCodeNumber) and the MessageHeader's 
name (fieldName). Additionally there are the corresponding "resource" 
properties method, statusCode and headerName. The idea was that the 
"literal" properties are required and the "resource" properties are 
optional. In case of a conflict, the "literal" properties win.

Methods are described in an additional RDF/XML file http-methods.rdf, 
StatusCodes in http-statusCodes.rdf, HeaderNames in http-headerNames.rdf 
(which is not ready yet). So we have a more or less static schema for 
the structure (HTTP-in-RDF_new_approach.rdfs) and three updatable files 
for references. This also removes the need for an extra namespace for 
header names. Now it's just another file to be published (and referenced).

I think we could talk about this in the next phone conference.
