The WikibaseManifest extension provides an API endpoint that allows for automated configuration discovery of the Wikibase it is installed on; the endpoint returns automatically discovered configuration information from the local Wikibase for use by external tools.



  • Download and place the file(s) in a directory called WikibaseManifest in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php :
    wfLoadExtension( 'WikibaseManifest' );
  • Optionally set equivalent entities, max lag and external services (see below)
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

	'items' => [
		'Q5' => 'Q15'

Maximum lagEdit
