(the suggestion is for XHTML/RDFa dreamweaver templates, which is a 
great idea)

I'd suggest an RDFa representation of their XMP metadata format is more 
likely to engage attention at Adobe than generic RDF/DC. I'm copying 
Larry Masinter, who I spoke to briefly at W3C's last Tech Plenary about 
this.  More about XMP here: http://www.adobe.com/products/xmp/ and 

Larry, have you looked at RDFa at all? Could you offer some pointers to 
help us sketch out some examples of RDF expressed in XHTML+RDFa?

Are http://www.adobe.com/devnet/xmp/pdfs/XMPSpecificationPart1.pdf and 
http://www.adobe.com/devnet/xmp/pdfs/XMPSpecificationPart2.pdf the best 
places to start? I remember XMP used to use a lot of the rdf:Bag, 
rdf:Seq, rdf:Alt constructs. So one thing to investigate here would be 
the extent to which data from other XMP-carrying environments (eg. 
inside PDFs, TIFFs) can be losslessly represented in human-facing RDFa. 
And on whether XMP-friendly profiles of RDFa usage (eg. some templates - 
such as might be suggested for Dreamweaver) can be produced.

Here is an example from XMPSecificationPart2.pdf
(one might imagine this in RDFa with some CSS styling):

<rdf:li xml:lang="x-default">XMP - Extensible Metadata Platform</rdf:li>
<rdf:li xml:lang="en-us">XMP - Extensible Metadata Platform</rdf:li>
<rdf:li xml:lang="fr-fr">XMP - Une Platforme Extensible pour les
<rdf:li xml:lang="it-it">XMP - Piattaforma Estendibile di Metadata</rdf:li>
</xmp:Title> "

Larry - looking at the spec, a lot of the examples are exercises in 
exploring corner-cases for parsing. Can you point us to any kind of 
repository of real world XMP examples?
