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.
InstallationEdit
- Download and place the file(s) in a directory called
EntitySchema
in yourextensions/
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
:Configure as required.wfLoadExtension( 'EntitySchema' );
- Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
ConfigurationEdit
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

A full list of the extensions installed on a particular wiki can be seen on the wiki's Special:Version page. |
