Uche,

There is a move to have a common set of test cases as well. We will need
defined data by then but guesswork is fine!

One of the things to get out of the use cases is a sense of where query is
used, as well as comparing languages.  My hope is that query users, not just
query system builders, will submit examples so we can see what people
actually use query for.

Great idea.

"the adoption of RDF systems inside exsisting Web infrastructures" is a very
important and I think too often understated goal.  I would also add the
adoption within XML processing systems.

There are no sample RDF files given alongside the use cases.  Without RDF
instance files, how can one test queries to make sure the given examples are
correct?  How can someone else really understand the query?

I'm about to go put up Versa examples, which unfortunately, since I have no
detail of the RDF models being queried, will have to be guesswork.
