Wikidata Query Service/User Manual

= Introduction = Wikidata Query Service is the software package and public service designed to provide a SPARQL endpoint which allows to query against Wikidata data set.

Please note that the service is currently in beta mode, which means some details of the data set or the service provided can be changed without prior warning. This page or other relevant documentation pages will be updated accordingly, it is recommended to watch them if you are using the service.

Data set
The data set is the data from Wikidata.org, represented in RDF as described in RDF dump format documentation. Please note the service data set does not exactly match the data set produced by RDF dumps, mainly for performance reasons - there is a small set of differences described in RDF format documentation.

Missing features
Below is the list of features which are currently not supported:
 * Geolocation search. While the coordinates themselves are part of the data set, the operations on these coordinates - like comparison, search within radius, etc. - are not yet supported.
 * Redirects are only represented as owl:sameAs triple, but do not express any equivalence in the data and have no special support.
