Add support for SPARQL 1.1 Service Description . The description would be reported for a GET against the SPARQL end point. We might want to extend the service description a bit to capture some of the bigdata specific semantics. We definitely DO NOT want to publish out all the named graphs in a quad store in the description, even if that is required for compliance. There can be WAY too many graphs in a quad store. Someone who has appropriate SPARQL access can always request the set of those graphs with a simple query.
