The RDF Data Access Working Group has published three SPARQL Proposed Recommendations: SPARQL Query Language for RDF, SPARQL Query Results XML Format, and SPARQL Protocol for RDF. The first specification defines the syntax and semantics of the SPARQL query language for RDF. The results of SPARQL queries can be results sets or RDF graphs; the second specification defines an XML format for the variable binding and boolean results formats. The third specification uses WSDL 2.0 to describe an HTTP protocol for conveying SPARQL queries to an SPARQL query processing service and returning the query results to the party that made the request. Comments are welcome through 10 December.
