Type constraint – instance of	taxon (Q16521)

Property constraints

• subject type constraint (Q21503250)
  • class (P2308) taxon (Q16521)
  • relation (P2309) instance of (P31)
• value-type constraint (Q21510865)
  • class (P2308) taxon (Q16521)
  • relation (P2309) instance of (P31)
• item-requires-statement constraint (Q21503247)
  • property (P2306) taxon name (P225)
• symmetric constraint (Q21510862)
• allowed qualifiers constraint (Q21510851)
  • property (P2306) object of statement has role (P3831)
• property scope constraint (Q53869507)
  • property scope (P5314) as main value (Q54828448)

For the following I'm not sure, until now I used it in order to make it clear that two homonyms are different and should not be confused but with the new property, since there will be a symmetric constraint, I don't know if is is necessar, me I would put that constraint, but well if someone has an arguments against, fine:

• item-requires-statement constraint (Q21503247)
  • property (P2306) different from (P1889)
  • constraint status (P2316) suggestion constraint (Q62026391)

Motivation

This proposal comes after this discussion [1] (see also this query), so at first it is planned to use it in order to harmonize and regulate the current ways of modeling taxonomic homonymy in Wikidata. In addition, me, I will add it every times I come across homonyms in the context of my contributions and this happens regularly. Note that this new property should have a symmetric constraint, and maybe an item-requires-statement constraint with different from (P1889). Christian Ferrer (talk) 21:03, 2 December 2024 (UTC)

• Also look at Wikispecies:Category:Taxon disambiguation pages to have a idea of the potential use of such property. Christian Ferrer (talk) 21:24, 2 December 2024 (UTC)

Discussion

•  Support. Here are 142 statements where the proposed property would aid in the depopulation of the to-be-deprecated of (P642). I would suggest, rather than an item-requires-statement constraint, that the proposed property simply be a child property of different from (P1889). Swpb (talk) 21:20, 2 December 2024 (UTC)
•  Support I support this but wish to draw attention to an issue that may need to be addressed here also. This is the issue of cross Code pauedo homonyms. Although no two names within a code can be identical you however have a plant and an animal for example with identical names. There are many of these in existence. In that situation both names are valid and hence there can be no supression of one over the other. However they should still be flagged for disambiguation peurposes. I would also suggest that any declaration of a name as a junior homonym needs to be supported by the primary literature as there are names where the senior Homonym is not the accepted name (for example Testudo terrestris where the senior homonym is actually the oldest name for the Mata mata but its junior homonym is considered valid). Hence the exact understanding of how the nomenclature was sorted needs to be considered. Cheers Scott Thomson (Faendalimas) ^talk 09:56, 3 December 2024 (UTC)
  • This property is indeed for disambiguation purposes, not at all intended to highlight the potential validity of those names nor to say if the names depend on the same code. That being said one can very well consider to use a qualifier such as object of statement has role (P3831) added to this new property for that kind of purpose, e.g. Nectria (Q18616886) homonym of Nectria (Q2708290) object of statement has role (P3831) hemihomonym (Q36033662), all symmetrically.

• The label should be "homonymous taxon" since the current one is too ambigous.--GZWDer (talk) 11:38, 3 December 2024 (UTC)
  • Well this makes sences, this will avoid that the property to be wrongly used, thanks you. Christian Ferrer (talk) 14:10, 3 December 2024 (UTC)
• Update as per suggestion above the label is changed from "homonym of" to "homonymous taxon", if the new label is not satisfactory we can also use something like "homonym (biology)". Christian Ferrer (talk) 14:10, 3 December 2024 (UTC)
• Update I added at top a list of Property constraints that I think could be useful. Christian Ferrer (talk) 15:55, 3 December 2024 (UTC)
•  Support I queried that we have around 4.4k taxon homonymns where this new property could be used. Making this a subproperty of (P1647) = different from (P1889) would replace the need of separate P1889 statements. While looking for other subproperties of P1889 I found out we have also this zoological name is coordinate with (P2743) which is probably worth adding to related property (P1659).
