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 #Configuration.

Installation edit

  • Download and move the extracted EntitySchema folder to your extensions/ directory.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/EntitySchema
  • 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( 'EntitySchema' );
    Configure as required.
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
