I've updated my Atom to RDF/XML XSLT transform to implement draft-06. I think that it implements everything, including:
* xml:lang and xml:base resolution * Structured and Simple Extension constructs * Resolving of defaulted atom:author elements. There is an RDFS schema of the model up there too. http://djpowell.net/atomrdf/0.1/ Does anyone else have any experimental draft-06 feeds available for testing? -- Dave
