The 'Cattle' item cannot accept the property 'this taxon is a source of'
[edit](Note: This is also posted in the inverse of this property)
I'm trying to connect foods to the type of organism that produce them, so one can tell if a food comes from a plant, animal, fungus, or bacteria. Cattle are an extremely common source of food (https://www.wikidata.org/wiki/Q830 ), and I'm noticing some irregularities that got established on some Wikidata items over time, for various reasons.
Because the 'Cattle' item is not an instance of a 'taxon', a property that is reasonably assumed to apply to 'cattle' will not validate under today's constraints. In particular, if you state that cattle produce 'cows milk', the system will throw a warning that a constraint is violated. The property P1672 and its inverse P1582 here have the constraint that the item be an instance of 'taxon' or 'common name' (https://www.wikidata.org/wiki/Property:P1582), but 'Cattle' is an instance of 'group of organisms known by one particular common name' (https://www.wikidata.org/wiki/Q55983715).
From reading through the long discussion on Cattle, one proposal was that cattle be tied into a taxonomy of organisms by citing it as an instance of an umbrella ancestor species. So 'cattle' will be described as an instance of Bos primigenius (https://www.wikidata.org/wiki/Q168903). This seems reasonable to me, and would solve my issue.
Another solution I'm suggesting for this property is to change the properties P1672 and inverse P1582, so they validate when using 'group of organisms known by one particular common name' (https://www.wikidata.org/wiki/Q55983715). They currently validates with 'common name' as well as 'taxon', so it doesn't seem like a big stretch to extend it to 'group of organisms known by one particular common name'. Is there anything or anyone stopping us from making this change?
P1672 with collectable wild foods
[edit]I’m planning to use this property on a number of wild species with items such as wild edible plant (Q91867273), wild herb (Q1318906), edible plant (Q9323487), edible seaweed (Q796185), edible nuts (Q3320037), edible seeds (Q2995529), edible mushroom (Q654236), edible insect (Q38117921) and similar. Are there any objections? -- Abuluntu (👨🏼💻💬) 22:36, 29 June 2021 (UTC)
Oppose This seems like very different semantics then for which the property was proposed. A wild species doesn't produce general edible nuts but particular one's that are linked to the species. ChristianKl ❪✉❫ 13:23, 14 July 2021 (UTC)
