On closer reflection I'm wondering if that even makes sense at all? Does
an HTML page describe a non-information resource? or does an information
resource describe an HTML page, and also link to what it describes?

for example; if the main content on the HTML page was a sioc:Post then

<http://example.org/mogwai-post#post> rdf:type sioc:Post ;
  foaf:primaryTopic <http://dbpedia.org/resource/Mogwai_(band)> ;
  foaf:page <http://example.org/mogwai-post.html> .

taking it further I guess the serialized rdf itself is a foaf:Document
too so:

<http://example.org/mogwai-post.rdf#this> rdf:type foaf:Document ;
  foaf:primaryTopic <http://example.org/mogwai-post#post> .

<http://example.org/mogwai-post.html#this> rdf:type foaf:Document ;
  foaf:primaryTopic <http://example.org/mogwai-post#post> .

then the <link> which is in the HTML document would be:

<link rel="alternate" type="application/rdf+xml"
href="http://example.org/mogwai-post.rdf" title="RDF XML" />
