The WikibaseQualityConstraints extension allows defining constraints on Wikibase Properties and checks that the constraints are met when the Properties are used in Statements on Entities. The checks are strictly informational: the extension does not ensure that the constraints are met, it merely informs editors when they are being violated. For more information, see the Property constraints portal on Wikidata.

Installation

• Download and place the file(s) in a directory called WikibaseQualityConstraints in your extensions/ folder.
• Only when installing from Git, run Composer to install PHP dependencies, by issuing composer install --no-dev in the extension directory. (See task T173141 for potential complications.)
• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'WikibaseQualityConstraints' );
  

• Configure as required.
•  Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Configuration

See the "config" section in the extension.json file.
