Ruben,

A SPARQL Endpoint can be self-describing, using terms from the SPARQL 
Service Description vocabulary [1]. The trouble is most endpoints don't 
implement this functionality.
curl -iH "Accept: text/turtle" http://dbpedia.org/sparql/ .

point that "use" rather than "existence" of service description 
capability is the prime issue).
