Hi Miguel, > for completeness I would add that as a fact also SPARQL endpoints MAY self-describe themselves in RDF using the "SPARQL 1.1 Service Description Vocabulary" [1]. Indeed, very good point. > By the way, I guess some other "brute force" methods can be used to test if an URL points to a SPARQL endpoint, like sending a very simple SPARQL 1.0 query. In practice, yes; in theory, not really. E.g., I could set up a server that responds to ?query=simple_sparql_query but not to any other query. Exotic example, I know, but the only hard guarantees are self-descriptive responses (assuming the server tells the truth—but you trust the server anyway if you're going to query). Best, Ruben
