Description	topic of a work, but not the main topic (see also P921: main subject)

Data type	Item
Domain	item
Example 1	Q1052692

Planned use	I will add a topic of my research monograph.
Expected completeness	eventually complete (Q21873974)

Motivation

Property:P921 is vastly not enough to describe topics of works.

We need also to create another property (I do not propose it, because it would refer to this property that yet has no property ID) to be a superclass of both this property and P921. VictorPorton (talk) 06:22, 26 February 2021 (UTC)[reply]

For example, my book "D, the Best Programming Language, for Former Python Developers" (not described at WikiData) could have Property:Q319268 as its main subject and PQ79872 (PQ79872) and several others as values of this property.

  - Comment @VictorPorton: The examples do not make much sense. I invite you to look at other proposals in to see what examples should look like. Then they could help the community understand the merits of your proposal. Vojtěch Dostál (talk) 19:26, 18 April 2021 (UTC)[reply]
Support, an important property for research.--Arbnos (talk) 01:47, 20 March 2021 (UTC)[reply]
Oppose incomplete proposal. I doubt this is going to be useful. Multichill (talk) 10:21, 1 May 2021 (UTC)[reply]
Oppose I think you read main subject (P921) to strictly. There's also discussion from me that explains a better path forward for everyone, I think.

Not done due to incomplete proposal and lack of consensus. --99of9 (talk) 06:46, 14 October 2021 (UTC)[reply]
