Property:P2086

P2086 (P2086): (delete | history | links | entity usage | logs)

As discussed in Property talk:P2086#How should it be used?, this property appears to be unusable. --Horcrux (talk) 16:50, 13 May 2024 (UTC)

Property:P2021

Erdős number (P2021): (delete | history | links | entity usage | logs | discussion)

The Erdős number property is a "continuously changes / unstable identifier" on items that are published humans, however, the number is not really a property of a person, it is a property of a person and an ill-defined collaboration graph at a particular point in time. Originally it was the collaboration graph of papers published in math journals, however it is more often than not extended far beyond math papers now. The description states that a point in time qualifier and a source should be used, which makes sense as the number is fairly meaningless without a point in time, however a sampling of the 2,447 instances of this property shows only a small fraction of usages have correctly-applied points in time and sources.

The proposal for this property at Wikidata:Property proposal/Archive/33 was deficient, simply stating "An obviously useful property," while it's not obvious to me that it's useful or apt at all, and a single "Support" vote with no explanation.

So overall, this property is a maintenance nightmare, is not being used correctly, it is not clear that the situation could ever improve, and really a well-defined property to apply to humans in the first place. —Anon20240724 (talk) 04:07, 21 July 2024 (UTC)

this is just a too well-known and established property within the mathematical community (even only on the small talk level) to be deleted. Why can not somebody write a bot/script to get the relevant data from mathscinet?Bocardodarapti (talk) 08:09, 21 July 2024 (UTC)
The fact that's it's unstable is not enough to justify deletion, Wikidata can handle evolution over time through "date" qualifier for example. We handle such datas as city number of inhabitants already, by adding a date qualifier. We can afford getting multiple values. 2A01:CB08:91C2:C300:E033:EA12:9A1E:2379 09:27, 21 July 2024 (UTC)
 Oppose For deceased researchers, the Erdős number will (eventually) become static. For living researchers, having a script to update the number would be great, but even without that, I think that periodic dated updates for would be good enough to be useful, or at least interesting. — The Erinaceous One 🦔 09:39, 21 July 2024 (UTC)
 Oppose It's not an identifier, stability is not an issue. ArthurPSmith (talk) 14:52, 22 July 2024 (UTC)
 Oppose It's also eventually stable anyway, as individual mathematicians go to meet theie peers in Mathematical Valhalla, where no-one ever runs out of chalk or blackboard space, so you don't have to worry about a number than continues to change forever. Changes in Erdős number are also of historical interest. But that's not the primary reason, it's that it's really fucking cool. 193.29.28.94 17:27, 22 July 2024 (UTC)

Property:P4547

P4547 (P4547): (delete | history | links | entity usage | logs)

Currently, a property has been created to replace the one being removed - Olympic Committee of Serbia athlete ID (new) (P10978). Since 2020, the above site has stopped working and now all identifiers are not in the form of numbers, but in the form of a first and last name. —MasterRus21thCentury (talk) 14:57, 26 August 2022 (UTC)

@MasterRus21thCentury: Is it possible to migrate the remaining 66 statements? --Ameisenigel (talk) 09:36, 21 June 2024 (UTC)
@GrandEscogriffe, Florentyna, Ajraddatz, Wüstenspringmaus: We still have 57 statements that have not been migrated. --Ameisenigel (talk) 12:51, 6 July 2024 (UTC)
@Ameisenigel I'm going to migrate them the next days. --Wüstenspringmaus talk 12:52, 6 July 2024 (UTC)
@Ameisenigel: Done. --Wüstenspringmaus talk 14:51, 9 July 2024 (UTC)
@Koavf: Could you have a look, please? --Wüstenspringmaus talk 06:22, 28 August 2024 (UTC)
It looks like all instances have been replaced. It's not immediately clear to me why how the property works wasn't just changed instead of a new property being created. Do you want me personally to delete it? If so, ping me again. —Justin (koavf)❤T☮C☺M☯ 08:48, 28 August 2024 (UTC)
@Koavf: I agree with you, but in any case it's no longer useful. I would delete it, but since I'm involved in the discussion, I haven't, and I would ask you personally to delete it. --Wüstenspringmaus talk 09:01, 28 August 2024 (UTC)
Gotcha. Can do now. —Justin (koavf)❤T☮C☺M☯ 09:04, 28 August 2024 (UTC)
