@Robin van der Vliet: It looks like this property has a distinct values constraint, but female form of label (P2521) does not. It's also causing a violation at chairperson (Q140686) and chairperson (P488) when it should not be. Any thoughts on how to resolve? {{u|Sdkb}} ^talk 20:51, 18 August 2021 (UTC)[reply]

I've launched the discussion here Wikidata:Project_chat#Why_are_labels_of_occupation_always_male_labels?. PAC2 (talk) 20:08, 27 October 2021 (UTC)[reply]

With Q14625123, we noticed an issue : this object is only pertinent for one gender (male or female), and the only way to know this is to check label. However, this way is usable only humanly. Currently, no property or rank allow to check it. The goal would be to allow SPARQL request to include or exclude value in a unique and explicit way.

Several solutions can be used, but each one I think of need a modification in the current use:

• I do not see an existing rank for this kind of value, a specific rank could be created, as `N/A`
• a `N/A` standard Q value could be acceptable for Property:P3321 or Property:P2521
• a new property could be created, asserting that the object only is usable for male or female objects.

Do you have any other ideas? I made a suggestion in Property_talk:P2521#How_to_manage_gender-specific_form_objects for male or female specific term.
