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.

Releasing

The Wikibase MediaWiki extension receives continuous updates as it is deployed on Wikimedia hosted sites.

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

Installation

• Download and move the extracted Wikibase folder to your extensions/ directory.
  Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone --recurse-submodules https://gerrit.wikimedia.org/r/mediawiki/extensions/Wikibase
• Only when installing from Git, run Composer to install PHP dependencies, by issuing composer install --no-dev in the extension directory. (See T173141 for potential complications.)Category:Extensions requiring Composer with git
• Add the following code at the bottom of your LocalSettings.php file:

  # Load Wikibase Repository
  wfLoadExtension( 'WikibaseRepository', "$IP/extensions/Wikibase/extension-repo.json" );
  require_once "$IP/extensions/Wikibase/repo/ExampleSettings.php";
  
  # Load Wikibase Client
  wfLoadExtension( 'WikibaseClient', "$IP/extensions/Wikibase/extension-client.json" );
  require_once "$IP/extensions/Wikibase/client/ExampleSettings.php";
  

• Run the update script which will automatically create the necessary database tables that this extension needs.
• Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

This extension is being used on one or more Wikimedia projects. This probably means that the extension is stable and works well enough to be used by such high-traffic websites. Look for this extension's name in Wikimedia's CommonSettings.php and InitialiseSettings.php configuration files to see where it's installed. A full list of the extensions installed on a particular wiki can be seen on the wiki's Special:Version page.
