###Instruction: Multi-class classification, answer with one of the labels:['no_consensus', 'delete', 'keep', 'comment', 'merge', 'redirect'] : ###Input:  Q15720718: Q15720718 : no description : ( delete | history | links | entity usage | logs ) Hello, this seems to be a kind of 'meta item' about types of music albums. There are 4 items for specific types (for example, live album (Q209939) ) linked to this item. They have the claim that they are an 'instance of' ( instance of (P31) ) this item. However all four have also the claim that they are a subclass ( subclass of (P279) ) of the more general item album (Q482994) . Hence the following two conclusions: Two months ago I asked about the use of this item on its talk page, but no-one responded. Instead of removing this item, redirecting it to album (Q482994) would perhaps also be okay. But I think it should not be used in any claims. Bever ( talk ) 00:19, 10 March 2015 (UTC) Isn't this item still in use? -- BeneBot* ( talk ) 08:05, 10 March 2015 (UTC) There are 4 items using this item as a target for P31, as I said. I thought perhaps you would like to see that. If necessary, I will remove those claims. Bever ( talk ) 12:41, 10 March 2015 (UTC) I have removed the P31 claims from the following items: So now the item is not 'in use' any-more. Bever ( talk ) 18:55, 12 March 2015 (UTC) I created the item, I should have been noticed. @ bever : For an explanation about this kind of items, see Help:Classification . Metaclasses can be useful, not every subclass can actually be in the range of a property for example. TomT0m ( talk ) 18:58, 12 March 2015 (UTC) @ Bever : And no, the item can definitely not be merged into album, this would really break the item/class relationship. And please, don't delete the claim while the discussion in unfinished. TomT0m ( talk ) 19:01, 12 March 2015 (UTC) @ Bever : See also metaclass (Q19478619) for an english wikipedia article about the metaclass concept in the semantic web. TomT0m ( talk ) 19:08, 12 March 2015 (UTC) Hello TomT0m , sorry for not notifying you. As no-one responded to my question at the item's talk page, I got the impression that nobody cared about it and thought "let's be bold". I can see that in a case like ship class (Q559026) , a well known phenomena, a two-fold relationship from the individual ship classes to both 'ship' and 'ship class', is necessary. But I wonder to which extent 'type of music album' will be used, as there are no sitelinks for the item. Everything which can be told about classification of music albums, is already told in the articles at album (Q482994) . Bever ( talk ) 19:48, 12 March 2015 (UTC) @ Bever : I have some doubts about statements on that item :) ⟨ album ⟩ subclass of (P279) ⟨ q2031291 ⟩ seems not really to make sense to me for example, this imply that every album is released if I understand well. Anyway some of the subclasses of album, for example Mickael Jackson album or whatever, are subclasses of album conceptually, may appear in Wikidata for some reason (it is an open world) and may break your assumption. In that view an item like album type make sense because it allows this to happen without problem, and is just another way to say the same things that are present in the article. It's instances are the main types of album used in the recording industry. PS: I guess someone you don't care about would need some information as well :) TomT0m ( talk ) 20:02, 12 March 2015 (UTC) Hello TomT0m , sorry for not notifying you.
