So what you want is to be able to make the category one possible search criteria when searching for images? We don't need an entity type for that I think. We "just" have to build the search interface in a way that it can take those into account as well from where they are already now. Or is that missing something important you had in mind? > Such categories (or sets) may well not be Wikidata notable, for example: > > Category:Pictures I took on my cellphone one midsummer morning > > so we cannot assume they have Q-numbers. My assumption so far was that we can assume every topic we use to tag images to be in Wikidata. Are there some examples currently in use on Commons that you think would not be covered? Because Wikidata will be used to tag much more than just Commons images in the future. So we should have a really huge vocabulary. > But it would be nice if we could describe such properties using the existing > Wikidata syntax, ie via a property Pxyz = "belongs to set", and then an item > number for the set it belonged to. What set is this for example? Like "everything takes as part of Wiki Loves Monuments 2012"? Or some other kind of set? > Since the items wouldn't be on Wikidata, it would be useful if they had a > different namespace, eg C nnnnnn Imho they should be on Wikidata. I fear if we introduce another layer it'll be considerably harder to use and maintain.
