SPARQLer - An RDF Query Server


SPARQL SPARQL (pronounced "sparkle", a recursive acronym for SPARQL Protocol and RDF Query Language) is an RDF query language, that is, a query language for databases, able to retrieve and manipulate data stored in Resource Description Framework format.[1][2] It was made a standard by the RDF Data Access Working Group (DAWG) of the World Wide Web Consortium, and is recognized as one of the key technologies of the semantic web. On 15 January 2008, SPARQL 1.0 became an official W3C Recommendation,[3][4] and SPARQL 1.1 in March, 2013.[5] SPARQL allows for a query to consist of triple patterns, conjunctions, disjunctions, and optional patterns.[6]
