Getting ahead of the use case, but I've long argued that if ODF was 
enhanced to offer out-of-box support for the rest of DC (including 
Qualified DC), bibliographic support could be covered with a handful of 
additional properties. Given that Open XML now supports DC and QDC 
(though *how* is still unclear to me), this seems a no-brainer to me.

I rather like the idea of thinking in terms of the RSS language of 
"modules."

I was never clear on this one. Is it really even a use case? I think 
not.

But certainly we'll need to deal with it at some point.  With RELAX NG, 
it's not hard to create a generic metadata validator. If you're talking 
a profile of RDF, you can't validate stuff like linking (e.g. the uri 
of this link matches an id for the endpoint), but you can certainly 
validate the basic structure of the XML.

Yeah, this is where the discussion came around to the observation that, 
from an XML standpoint, metadata would need to be encoded as elements 
rather than attributes. But it is, of course, tied up in larger issues.
