SPARQL (pronounced "sparkle", acronym for SPARQL Protocol And RDF Query Language) is an RDF query language, that is, a semantic query language for databases. With SPARQL you can extract any kind of data, with a query composed of logical combinations of triples.

Wikidata provides an SPARQL endpoint including a powerful Web-GUI since September 2015.
