Subclass constraint

[edit]

This property has a constraint requiring that values be subclasses of minor planet group (Q6188101). Does this make any sense? Looking at the hierarchy above, there are some very strange implications. For example, an accepted value is distant minor planet (Q5282923). distant minor planet (Q5282923) is listed as though it should be a subclass of minor planet group (Q6188101), which would imply that every instance of distant minor planet (Q5282923) would also be an instance of minor planet group (Q6188101) by extension, but distant minor planets are not each minor planet groups. (Currently, the item is listed as being a subclass of minor planet (Q1022867) instead, which seems much more correct.)

Perhaps the constraint should be either requiring instance of (P31) minor planet group (Q6188101), or subclass of (P279) minor planet (Q1022867), instead? --Yair rand (talk) 16:03, 29 November 2015 (UTC)[reply]
