Setting aside the discussion of 303, I'm not sure that rdfs:seeAlso is
the best property to use here. IMHO, rdfs:seeAlso works best for the
"RDF hyperlinking" that FOAF encouraged. I still tend to use it in
that form.

Typically when I'm pointing from RDF to a human-readable page then I
usually use one of the foaf "topic" properties. foaf:isPrimaryTopic of
would seem to fit here:

http://xmlns.com/foaf/spec/#term_isPrimaryTopicOf

I also think its more useful for agents that are looking for
human-readable pages.

Cheers,

L.
