"catalog for the item" as "catalog produced or published by or for the item (where item = exhibition or similar)", evidenced by the example on the talk page https://www.wikidata.org/wiki/Q15087813 which has a catalog property to store the catalog it "owns". Your suggestion to replace "for" with "includes" seemed reasonable to me, but that is not what the "for" means apparently. The language is not clear, and my longer attempt above isn't great either. The main point is that "for" means something like "owned by" and not "which it is a member of" >From the intent of the description and examples in https://www.wikidata.org/wiki/Property_talk:P972 it looks like P972 as a qualifier imparts the sense of item is "member of <catalog>", but as a property means item is "owner of <catalog>" I'm not sure that dual usage makes sense, and certainly it has caused confusion in how the property is used, since the bulk of the usages of P972 as a property appear to intend "member of <catalog>", but are indistinguishable from those that intend "owner of <catalog>", which is apparently the correct use. I said I'd take this up further on the property talk page, which I will. Just wanted to make a non-obvious correction in case the confusion spread. I'm also happy to see another concrete example of this misinterpretation, so it's not just me! Charles.
