Thanks for the summary! As I said, I'm none too familiar with RDF- I
suggested it because it seems to work well for things such as Creative
Commons licenses, which can almost be visualized as another
"capability": they have a distinct URL that associates with a Work (in
the case of YADIS, a Consumer). Furthermore, the use of the rel="meta"
construction seems to have a fairly wide basis, being recommended for CC
and Dublin Core metadata. Other formats, like RSS, incorporate RDF
directly into the schema, allowing for RDF+CC/DC/YADIS (RCDY?) to be
embedded directly, or included via XInclude or an XSL stylesheet.

I must say that in recent months, programs like xsltproc have made an
XML-lover out of me- not because XML itself is so wonderful, but because
it is a well-understood standard with lots (and I do mean lots) of
developer support available. Seems to me, why reinvent the wheel? RDF
seems like it was designed- or at least is widely used- for exactly this
kind of purpose, and that mechanisms exist to couple RDF to arbitrary
XML documents.
