Class or group? edit
This item currently uses has part(s) (P527) to link to sub-breeds like Bokhara (Q7770659). This could work, assuming that the item was referring to a group instead of a class, but I don't think that's the case. This item already uses subclass of (P279) to link to domesticated pigeon (Q204179) and fancy pigeon (Q5433715), and not part of (P361). Thus, it is a class. A class using has part(s) (P527) means that every instance of said class has such parts, which is clearly incorrect.
(Pinging @PigeonIP: who made the edits.)

@Yair rand: The problem with subclass of (P279) is, that every link to domesticated pigeon (Q204179) gets deleted, because fancy pigeon (Q5433715) is a subclass of (P279) domesticated pigeon (Q204179).
- subclass of (P279) domesticated pigeon (Q204179) is very important, because domesticated pigeon (Q204179) is the last Taxon! It is important for many use-cases that this link exists (directly).
- not every breed of domesticated pigeon (Q204179) is a fancy pigeon (Q5433715) and not every fancy pigeon (Q5433715) is a domesticated pigeon (Q204179) (at least in the US, in other countries every fancy pigeon (Q5433715) subclass of (P279) domesticated pigeon (Q204179)) Similar things are taking effect for domestic ducks and geese (both are two species and crossbreeds in the case of geese) and cows (5? species and some hybrids).
- in the world of pigeon-breeding there are many associations with theire own (sometimes incompatible and conflicting) definitions of breeds and subbreeds, breedgroups etc.
- and many, many more.
I used has part(s) (P527) after a long discussion with I think User:Succu [1] and others on many, many pages as for example the Project Dog breeds and Wikidata:Forum, some userpages, subpages, ... .
Sorry for beeing very tired of discussing "the right way". My goal was to find a managable system in a very complicated world of pigeonbreeding (even if it is temporarely first, but without it, it -the explaining thing to non(pigeon)breeders- would be even more complicate to define properties that might work). We are talking about more than 800 breeds for pigeons only.
It is not possible, so I left this project (including merging and splitting items, adding original names, ref. translations of names, ...). I am doing other things now. --PigeonIP (talk) 11:43, 20 July 2016 (UTC)
