The EntitySchema extension allows storing Shape Expressions Schemas on wiki pages (using ShExC syntax), as well as validating entities against those Schemas using the ShEx2 — Simple Online Validator. For more information on enabling this second part, see #Advanced Configuration.

Installation

• Download and place the file(s) in a directory called EntitySchema 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 T173141 for potential complications.)
• Add the following code at the bottom of your LocalSettings.php:

  wfLoadExtension( 'EntitySchema' );
  

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

Advanced Configuration

Prerequisites for displaying the optional "check entities against this Schema" link on the Schema page:

• In your LocalSettings.php, set $wgEntitySchemaShExSimpleUrl to a non-empty string which represents the external verification tool to use (e.g. https://tools.wmflabs.org/shex-simple/wikidata/doc/shex-simple.html).
• The link is only displayed on pages where the Schema text is not empty
