# RDF binding

Wikibase allows exporting data in RDF format. See details of the implementation in [RDF Dump Format](https://www.mediawiki.org/wiki/Wikibase/Indexing/RDF_Dump_Format)

Changes to the RDF mapping are however subject to the Stable Interface Policy, see [Wikidata:Stable Interface Policy](https://www.wikidata.org/wiki/Wikidata:Stable_Interface_Policy).
