Hi,

Is the constraint (and the warning) wrong or is it your statement? I'm pretty sure this is the second. The ideal category should be "Category:Cows in heraldry" not "Category:Heraldic figures" (which is already use on https://www.wikidata.org/wiki/Q3744866 ).

When dealing with Wikipedia Categories and placing statements about a "topic's main category" P910 https://www.wikidata.org/wiki/Property:P910 on a symbolic representation topic of "cow" here https://www.wikidata.org/wiki/Q4007160

A Potential Issue appeared today that puzzled me: "Category:Heraldic figures" should also have the inverse statement "category's main topic `cow`"

Category:Heraldic figures is much more about just "cow's". And so I wouldn't want to say that the category's main topic is "cow" ! I would think that many categories "could" always be about many things, and so this inverse property constraint on P910 seems overly protective *and also seems to be encouraging users to add bad, erroneous information.*

So, I wonder if this constraint should be removed or special cased somehow somewhere or at some level elsewhere?

See attached screenshot.
