Hello all,
In the past few months, the development team has mentored a student, Olga,
to help us developing a user script
<https://www.wikidata.org/wiki/User:Jonas_Kress_%28WMDE%29/check_constraints.js>
that displays the constraints on the item pages.
To use the script, add the following line to your user/common.js:
mw.loader.load(
'//www.wikidata.org/w/index.php?title=User:Jonas_Kress_(WMDE)/check_constraints.js&action=raw&ctype=text/javascript'
);
You will see an icon [image: Icon used on the user script for constraint
reports on Wikidata]
<https://commons.wikimedia.org/wiki/File:Constraint_icon.png> next to
violations. When you click it you will see the full report.

This script is based on a new API module for constraint checks
<https://www.wikidata.org/wiki/Special:ApiSandbox#action.3Dwbcheckconstraints.26format.3Djson.26id.3DQ2>
that one can use to check constraints on items and statements. At the
moment, the constraint checks are only derived from the property discussion
page constraint templates, not directly from statements. They are then
stored in a database table. We are running a script to update this table
every now and then or when you ask for it. Also note that some constraint
checks are disabled (for example the format check). In the future we will
support adding and updating constraints on property statements and we will
implement support for some constraints that are currently still missing.
If you try it, feel free to give us feedback! You can also add comments or
subtasks on Phabricator (see the ticket for the API module
<https://phabricator.wikimedia.org/T102757> and the user script
<https://phabricator.wikimedia.org/T97018>).
If there is no major disagreement, we would like to turn this script into a
gadget in the next days.
Thanks go to Olga and all the developers that helped her providing this new
feature :)
