To be more precise: http://www.w3.org/TR/void/#well-known This states that on domain www.example.com, the URI http://www.example.com/.well-known/void can be expected to be a redirect to an RDF document that describes any RDF datasets hosted on that domain, expressed in the VoID vocabulary. Looking for void:sparqlEndpoint triples in such a VoID description would yield the endpoint URL. Best, Richard > > A related question is SPARQL endpoint fingerprinting...
