RDF query language
||It has been suggested that this article be merged with Resource Description Framework. (Discuss) Proposed since May 2016.|
SPARQL is emerging as the de facto RDF query language, and is a W3C recommendation. Released as a Candidate Recommendation in April 2006, it returned to Working Draft status in October 2006, due to open issues. It returned to Candidate Recommendation status in June 2007. On 12 November 2007 the status of SPARQL changed into Proposed Recommendation. On 15 January 2008, SPARQL was standardized.
