Wikidata and Wikibase architecture documentation

Architecture Overview

Welcome to the Wikidata & Wikibase architecture documentation. The canonical place to read these docs is on Github Pages.

Here you will find a high level overview of Wikibase, its surrounding systems, and some details relating to specific cases and deployments such as Wikidata.

Systems are documented using arc42 structured templates. You can read more about this method at docs.arc42.org.

Wikibase Systems

Wikibase has expanded far beyond the initial MediaWiki extension that was created called Wikibase.

Multiple other MediaWiki extensions, and other surrounding systems now make up part of the Wikibase system landscape.

To simplify things the whole system is represented as Repository, Query Service and Client.
