We also have documentation for advanced users that goes beyond the first steps. The Wikidata Query Service provides a SPARQL endpoint including a powerful Web-GUI. SPARQL (pronounced "sparkle") 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.
