SPARQL

Pronounced "sparkle," SPARQL is a query language from the W3C for searching data defined in the RDF format. RDF is used to identify data on the Web to provide more targeted answers to a search. For more information, visit www.w3c.org/2009/sparql/wiki/Main_Page. See RDF, OWL and Semantic Web.
