	Shucks, do I have to give up my 'secrets' before I'm ready to demo ;) ?!?

	Oh well, Ed let the cat out of the bag, so here's a tasty link for you all:

	http://sourceforge.net/projects/d2rq-map/

	{there are other projects which do this, but this one fits the bill for us..it
	has sesame and Jena integration which is nice}
	
	I hope to release a URL to a test server in the coming weeks so that we can
	see this in action (practical application!!). We are also preparing a user
	tool which would overlay this repository so that the scientist doesn't have
	to author SPARCL, or worry about changing RDF into VOTable.

	laters,
