Example 3
(Note that set of imaginary numbers (Q47310259) is a part of set of complex numbers (Q26851286), and the P2670 value of set of imaginary numbers (Q47310259) is a subclass of the P2670 value of set of complex numbers (Q26851286) (imaginary number (Q9165172) subclass of (P279) complex number (Q11567)))
Example 4
< hydrogen fluoride (Q2468)     > has part (P527)   < fluorine (Q650)     >
value is subclass of that of search < hydrogen halide (Q1572088) >

(Note that hydrogen fluoride (Q2468) is a subclass of fluorine (Q650), and the P527 value of hydrogen fluoride (Q2468) is a subclass of the P527 value of hydrogen halide (Q1572088) (fluorine (Q650) subclass of (P279) group 17 (Q19605)))

MotivationEdit

In many cases, there are similar tree structures among parallel concepts. These proposed qualifiers are useful to explicitly clarify these relationships, and to check if the relation is broken. See also Wikidata:Property proposal/value is inherited from.

  Notified participants of WikiProject Medicine: These qualifiers are especially useful to describe medical concepts. --Okkn (talk) 15:10, 20 August 2018 (UTC)

As per Pasleim's suggestion, we would deal with this property as a source property, instead of qualifiers. So I chaged the description. --Okkn (talk) 12:20, 12 September 2018 (UTC)

DiscussionEdit

  •   Comment I don't see how this adds value to wikidata - it looks like a duplication of information which can be derived from the relationships on the values of these statements. Or maybe I'm missing something here? It seems at the least a confusing way to go about this... ArthurPSmith (talk) 20:11, 20 August 2018 (UTC)
    @ArthurPSmith: Thank you for commenting. For example, lung cancer (Q47912) is a subclass of respiratory system cancer (Q7315926) (pathological condition (cancer) is specified, but affected organ is NOT specified) and lung disease (Q3392853) (pathological condition is NOT specified, but affected organ (lung) is specified).
subclass of
  respiratory system cancer   edit
▼ 0 reference
+ add reference
  lung disease   edit
▼ 0 reference
+ add reference
+ add value
If we have qualifiers "value is subclass/part of that of" and "value is inherited from", the anatomical location (P927) claim in lung cancer (Q47912) can be represented as follow:
anatomical location
  human lung   edit
value is inherited from lung disease
value is part of that of respiratory system cancer
▼ 0 reference
+ add reference
+ add value
By doing so, we can explicitly declare the detailed relationships between the subject class and its superclasses, i.e. everyone can understand why respiratory system cancer (Q7315926) is a broader concepts than lung cancer (Q47912).
Of course if the data are complete, this information can be automatically generated. But practically, data are sometimes missed or changed mistakenly. We can detect not only ①mistakenly removing or changing of P279 claims in the subject class, but also ② mistakenly removing or changing of some inherited values in the superclass, by using these qualifiers. When editing in the superclass, we sometimes fail to notice the existence of subclasses, and in order to resolve interwiki conflicts or to fix the wrong external IDs, we would change some values. These qualifiers prevent us from causing mismatching in P279 claims in the subclasses.
However, we must beware that any bot should not automatically change these qualifiers according to the changes in the superclass. --Okkn (talk) 06:02, 21 August 2018 (UTC)
  • This still seems overly hard to follow - is it really necessary? Pinging the taxonomy project here.. ArthurPSmith (talk) 18:29, 23 August 2018 (UTC)
    • I believe these qualifiers are necessary to actualize high robustness of data and their structures. That is particularly vital for healthcare information, I think. --Okkn (talk) 18:44, 23 August 2018 (UTC)

  Comment My first impression also is that it looks complicated, and does not seem to be adding new information. It may help in adding robustness, but I can't really say if this would be worth it. Would this be used as a qualifier? - Brya (talk) 04:54, 24 August 2018 (UTC)

  • @Brya: Yes, they would be used as qualifiers. Not only robustness but also the notation of value inheritance (where the value is inherited from, or how the value is updated from superclass), would be added. --Okkn (talk) 06:57, 24 August 2018 (UTC)
