The Link header is certainly a candidate. The current status AFAIK is
that Mark Nottingham prepared an I-D describing it. I believe that it
has expired [1]

There was some more recent discussion (around [2]) about whether the
link header should be aligned to HTML link types or Atom link types, and
the difficulty was in the conflicting syntax.

What link type would be appropriate? "meta" seems to have the right
semantic but neither HTML 4 [3] or HTML 5 [4] seem to define it. We'd
need it to be stronger than a generic rdfs:seeAlso, but less specific
than rdfs:isDefinedBy. An "isDescribedBy" relation would be preferable
so that needs to be specified and documented somewhere.
