subclass tree
[edit]@TomT0m, Infovarius: - This item links to set (Q36161), which is a mathematical concept. Can one of you find the appropriate item for the subclass-of-tree? -Tobias1984 (talk) 22:06, 16 May 2014 (UTC)
- @Tobias1984: not an easy one, I suppose we need a good upper ontology to express that. @Emw: I did not read the BFO ontology paper fully yet, is there any answer in there ? TomT0m (talk) 22:18, 16 May 2014 (UTC)
- @TomT0m: - It really looks weird looking at this tree: http://tools.wmflabs.org/wikidata-todo/tree.html?q=246672&rp=279&lang=de -Tobias1984 (talk) 22:20, 16 May 2014 (UTC)
- Yeah, I an reluctant to insert concepts of the field mathematics as bases for our ontology, though of course instance of (P31) and subclass of (P279) may have strong mathematical basis. This would entail some kind of autoreference in the model. TomT0m (talk) 22:26, 16 May 2014 (UTC)

- I believe that mathematics can describe any object (may be not in present but potentially) :) --Infovarius (talk) 21:37, 18 May 2014 (UTC)
- Someone tried, see Principia Mathematica (Q163335)
, someone answered this would not be easy :) Gödel's incompleteness theorems (Q200787) . Maybe we would be safer creating a property to describe something similar to a reflection principle (Q7307249), such as P Wikidata's mathematical reflection of ... or something :) TomT0m (talk) 11:00, 19 May 2014 (UTC)

Metaclass
[edit]Cdo256, I don't think this item is intended as a metaclass. For example, Ling-Ling and Hsing-Hsing (Q684604) is an instance of group of living things (Q16334298). Instances of metaclasses however are classes (abstract objects). Though, it's confusing indeed as there are some contradicting (probably unwanted) statements around as well, e.g. lately someone has set "taxon" as a subclass of this item. 2001:7D0:81F7:B580:ECFC:C751:C1CE:F5E7 14:58, 17 September 2020 (UTC)
- @2001:7D0:81F7:B580:ECFC:C751:C1CE:F5E7 Ah okay, I didn't previously make the distinction between groups and classes. I'm going to read more about this before I make any further change related to groups and classes. --Cdo256 (talk) 16:05, 17 September 2020 (UTC)
- The problem was, that "group of living things" and "class of living things" have been the same items, some time ago.
- Yet, nowadays these are two different items: group of living things (Q16334298) as class and group or class of organisms (Q21871294) as metaclass. This solved the problem.
- For example, "Ling-Ling and Hsing-Hsing" is instance of group of living things (Q16334298) and "house cat" is instance of group or class of organisms (Q21871294). --Eulenspiegel1 (talk) 20:46, 18 September 2020 (UTC)
Cdo256, please see prior comments. In your recents edits this is again mixed up with group or class of organisms (Q21871294). 2001:7D0:81F7:B580:1008:1C6:8878:FFD7 15:08, 24 December 2020 (UTC)
- Ah, I got confused by current statements again, as apprently they were just left unfixed, not mixed up again. 2001:7D0:81F7:B580:1008:1C6:8878:FFD7 15:16, 24 December 2020 (UTC)
