As mul is being released on Wikidata T330281, we need to look into how this will affect Property Constraints.
One that will be affected is 'Label in Language'. In this case, we must decide on whether we mul labels meet the requirement for the property constraint.
This was discussed on the Property Constraints Portal.
Examples
A property that has the constraint Deutsche Synchronkartei film ID
And the current violations of the property constraint
Solution
For the 'Label in Language' constraint checker, the property constraint needs to be updated to include mul values for all languages
Steps to check
- Set up Wikibase Quality Constraints on the wiki
- Create a property with the 'Label in Language' constraint with qualifier language code AA
- Use the property on an Item with a mul label
- See if it produces any violations
