Motivation[edit]
When I tried to make Q18674452 link to Q1879781, I had to use Property:P527 which as we all know isn't too accurate. Besides, Property:P31 has an inverse label, Q65933034, but no actual property. What gives? Shāntián Tàiláng (talk) 16:48, 25 January 2023 (UTC)
Discussion[edit]
Oppose Those 'inverse property items' are specifically intended to hold labels to be displayed by a tool such as MediaWiki:Gadget-relateditems.js. Mahir256 (talk) 18:47, 25 January 2023 (UTC)
Strong oppose Definitely not, instance of (P31) should not have an inverse. ArthurPSmith (talk) 20:19, 25 January 2023 (UTC)- I believe different from (P1889) works, at least for these examples. -wd-Ryan (Talk/Edits) 03:55, 26 January 2023 (UTC)
- It also seems that most of these shouldn't be instances of them. -wd-Ryan (Talk/Edits) 04:00, 26 January 2023 (UTC)
- Oppose Not everything is supposed to be linked in both directions. In these cases, linking in one direction does the job. Additionally, the examples are about subclasses and not instances. ChristianKl ❪✉❫ 17:35, 26 January 2023 (UTC)
- Oppose There are only few cases in which inverse properties provide actual benefit. As far as I can tell, this is not one. --Nw520 (talk) 21:29, 30 January 2023 (UTC)
