Hi Lee,

My two (actually one :-) ) pences is how full negation can be expressed with SPARQL.


P.S. No need to say that a "SPARQL by Example" tutorial is highly appreciated :-)

Betreff: soliciting your favorite (public) SPARQL queries!

Hi everyone,

I'm putting together a "SPARQL by Example" tutorial, which is, as the 
name suggests, a step-by-step introduction to SPARQL taught almost 
entirely through complete, runnable SPARQL queries.

So far, I've gathered a great deal of example queries myself, but I know 
that many subscribers to these lists probably have favorite queries of 
their own that you might be willing to share with me.

I'm looking for:

1) SPARQL queries
2) ...that can be run by anyone (no private data sets)
3a)...either by running the query against a public SPARQL endpoint
3b)...or by using a public SPARQL endpoint that will fetch 
HTTP-accessible RDF data (e.g. sparql.org or demo.openlinksw.com)
4) ...that answers a real* question
5) ...and that is fun!**

* real is in the eye of the beholder, I imagine, but I'm not looking for 
  "finds the predicates that relate ex:s and ex:o in this sample RDF graph"

** fun is also in the eye of the beholder. fun can be a query on fun 
data; a clever query that may illustrate a particular SPARQL construct 
("trick"); a query that integrates interesting information; a query with 
surprising results; etc.

thanks to anyone who is able to contribute!

PS I plan to make the tutorial slides available online under an 
appropriate CC license once they are completed.
