How can I tell what dataset, functions, or extensions a SPARQL endpoint supports?
There is currently no established, interoperable method for representing or accessing functional descriptions of SPARQL endpoints. (This is not to be confused with the WSDL which describes the SPARQL Protocol itself.) The Data Access Working Group postponed this topic in 2005, leaving behind a draft “of historical interest only.” In the meantime, implementations have devised their own vocabularies and techniques for specifying and advertising the services and datasets supported by a SPARQL endpoint. For example, HP Labs’ Joseki allows service descriptions to be specified with an RDF configuration vocabulary. See the SPARQL service description wiki page for more information.
