TASK DESCRIPTION Constraints are an integral part of keeping Wikidata's data quality high. We need to understand them more in order to see how they can be improved further. @abian is looking into how constraints are defined and used right now on Wikidata: https://meta.wikimedia.org/wiki/Grants:Project/Rapid/Abi%C3%A1n/Study_on_Wikidata_property_constraints As part of this task we want to better understand the constraint violations - so the cases where data does not conform with the constraint definition. Among others we want to learn more about: - How many violations are there? How does it develop over time? - Are violations clustered around certain datatypes or properties? - Do violations get fixed? By hand or mass-edits? - What percentage of violations are false alarms (e.g. exceptions or bad constraint definition) and which ones really should be fixed (e.g. legitimate error in the data)? **Notes** - this will probably become easier with T192565 <https://phabricator.wikimedia.org/T192565> being solved - https://angryloki.github.io/wikidata-constraint-violations/ might be useful TASK DETAIL https://phabricator.wikimedia.org/T241543 EMAIL PREFERENCES https://phabricator.wikimedia.org/settings/panel/emailpreferences/ To: Lydia_Pintscher Cc: Tpt, Lydia_Pintscher, abian, Aklapper, darthmon_wmde, Nandana, Lahi, Gq86, Lucas_Werkmeister_WMDE, GoranSMilovanovic, QZanden, LawExplorer, _jensen, rosalieper, Agabi10, Scott_WUaS, Wikidata-bugs, aude, Mbch331
