Wikibase is a collection of software (applications and libraries) for creating, managing and sharing structured data.

This page specifically talks about the Wikibase MediaWiki extension.

Just installing the MediaWiki extension will not provide you with other elements of the Wikibase software toolbox, such as a query service, quickstatements etc.

Releasing

The Wikibase MediaWiki extension receives continuous updates as it is deployed on Wikimedia hosted sites via the normal REL_ branches, tags and downloads.

Wikimedia Germany also makes regular releases of this extension as part of Wikibase/Suite, in the form of OCI (Docker) container images.
