Hello Sebastian,

You are making me nostalgic for a dispute I lost by shout-down with with the developers of RDFa :o)

Oops.  Mr Erickson just beat me to the punch ... the critical point is that 
HTML has two bowls of tag soup (HEAD, BODY) related by proximity not by 
authority.  It's easy to assume that the HEAD is "global" to the BODY or vice-versa.  What you really want to do is cite a bibliographic 
reference to a set of RDF triples.

You can link to that file, or if you want to get fancy, embed an XML Bibliographic Reference format like MODS from the LoC[1].  Embedding in the BODY is more polite, and reassuring if questions arise about download size.

[1] Sorry, I have not looked at this in years so there will be some syntax issues.  The idea is simple, MathML for people who do math, MODS for people who keep track of written stuff.

Sebastian, is the requirement that the RDF not be *integrated* with
the content of the page --- in other words, you just want to embed a
"dump" of some RDF?

Why not link to a RDF or TTL file?
