For some specification of HTML to be developed/ratified, right?
The existing HTML specs don't already tell you how to get RDF
out of HTML documents; they don't tell you the full URI
for license in rel="license" in particular. And there isn't
a trail from the HTTP headers thru the MIME registry to
an HTML spec that cites the RDF spec normatively.
I think it is reasonable to interpret HTML documents
this way; i.e. it's consistent with the intent of authors.
We just need to get the HTML spec to say what's going on
clearly.
hmm... it's a little ironic... the title of the 1st HTML
Internet Draft was
Hypertext Markup Language (HTML)
A Representation of Textual Information *and MetaInformation*
for Retrieval and Interchange
