RDF is a definite possibility for this.  I am looking at the SemWeb
library for this. (http://taubz.for.net/code/semweb/)

Another possibility is to store it in a more straightforward relational
database and then build RDF from that later.  (This was more or less our
current plan with Lucene.)

Like I said, I'll have to build a prototype and see what works and
scales and what doesn't.  Fortunately I have millions of documents I
regularly test on, so I should be able to give it a good once over.

One thing I'm not sure on is that you talk about RDF being a perfect
"exchange mechanism" for your data.  Do you mean sharing common
namespaces like Dublin Core?  Common ways of expressing RDF like RDF-XML
or N3?  Or something else?
