An RDF query language is a computer language, specifically a query language for databases, able to retrieve and manipulate data stored in Resource Description Framework format.

SPARQL is emerging as the de facto RDF query language, and is a W3C recommendation.[1] 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.[2] On 12 November 2007 the status of SPARQL changed into Proposed Recommendation.[3] On 15 January 2008, SPARQL was standardized.[4]
