We decided to drop the merely advisory material about how to use SPARQL, and 
leave that to the FAQ.  But discovery of a SPARQL endpoint got forgotten in the 
change (I think it was never really specified previously).

I think the cleanest solution would to to introduce another link relation for a 
SPARQL query endpoint (but to not get into details of how to formulate the 
queries, other than to say that they are presented via SPARQL HTTP protocol, and 
executed over provenance formulated as RDF according to PROV-O).

I'll raise an issue for this.

Tracker, this is issue 609
