Actually, this is something I hope to be talking about internally 
today.  Specifically, I want to investigate and write up soon the 
best practices on how to extend the dublin core to best suit needs 
of users that we can't speculate ourselves.

I also added in some Links last night in the proposals area (found 
at the bottom of the page) linking to a couple of Dublin Core 
documents, posted there for informational purposes only.

http://cmf.zope.org/rqmts/proposals/

On a somewhat related note (this also relates to the "historical 
documents" thread), look at the metadata at:

http://www.dublincore.org/documents/dcmi-type-vocabulary/

------------
Identifier:
http://dublincore.org/documents/2000/07/11/dcmi-type-vocabulary/

Replaces: 	
http://lcweb.loc.gov/marc/dc/typequalif-20000519.html

Is Replaced By: 	
Not Applicable

Latest version: 	
http://dublincore.org/documents/dcmi-type-vocabulary/
------------

The URL in 'Indentifier' is the real location of this document - if 
you visit this URL even when a new revision exists, you'll always 
get *this* particular draft.  Similar to W3C documents.

The Replaces and 'Is Replaced By' are interesting relations (we 
have a proposal about the Relations elements on the dogbowl as 
well), so you can navigate through revisions of the document.

'Latest version' gives you a URI that always renders the current 
(published) revision of the document.

I just wanted to point to this as a real world pattern for those 
thinking about / working on the 'historical' revisions of 
documents.  This pattern works really well for proposals and 
recommendations, and is something I'd like to see in the in a site 
like the dogbowl soon.
