Joseph,

Thanks for the ping! It would be great to have some RDF IG folks
participate. I'm going to be in the wrong country at that time, but if
someone from RDFland could attend I think that'd be very useful, in the
spirit of Cambridge Communique, semantic web-o-trust and all that...

Any takers? As an aside I've been rather hackily signing and
encrypting various of my XML/RDF files with GPG 
(http://www.gnupg.org/) which lets me get by, experiment with provence
tracking RDF stores etc, but I'm very much looking forward to encryption
and digital sigs being more smoothly integrated with the XML
infrastructure. Sounds like a challenging workshop...
