Re: SOURCE test case sketches from users, please?

Here one of mine [sorry for the lateness]

A user wanted to get a list of papers from our computer science research
KB, but he only wanted ones that probably weren't processed by some
heuristics based nataural language software, so hte query (in DAWG speak)
was:

	SELECT ?id ?title
	WHERE SOURCE ?src (?id dc:title ?title)
			  (?src dc:creator ?creator)
	AND ?creator !~ /^Armadillo/

assuming a direct relation between the SOURCE node and the document URI,
and

	SELECT ?id ?title
	WHERE SOURCE ?src (?id dc:title ?title)
		          (?src dawg:source ?doc)
		          (?doc dc:creator ?creator)
	AND ?creator !~ /^Armadillo/

if not. s/dawg:source/dc:source/ if you prefer

I would say this is typical of the kind of thing that users do with
3store's SOURCE equivalent.
