Discussion

Untitled

Discussed at Talk:Q28640 (profession).

• Oops. Isn't it the same as P:P101? Infovarius (talk) 18:32, 15 April 2013 (UTC)

  I brought up that possibility (see my last comment on the archive link), but noted that the domain was different (P101 has a person domain). Superm401 - Talk 19:50, 15 April 2013 (UTC)

• By the way, in Wikidata:List of properties this property is described incorrectly. May be to use as typical taxon indeed? Infovarius (talk) 18:36, 15 April 2013 (UTC)
  • Thanks. Fixed. --  Docu  at 18:41, 15 April 2013 (UTC)

Constraint

Can this be extended to allow not only professions but also occupations, i.e. instances of occupation (Q13516667), too? -- Gymel (talk) 07:24, 9 September 2014 (UTC)

I think so. Let's try. --Infovarius (talk) 06:50, 13 September 2014 (UTC)

That was not very convincing (diff). I'm changing the template parameter to "subclass" now, perhaps that still includes instances. -- Gymel (talk) 17:04, 18 September 2014 (UTC)

@@Infovarius: No, that didn't include instances, thus the report became dramatically worse. Reverted it. -- Gymel (talk) 09:37, 20 September 2014 (UTC)

"Field of" qualifications or degrees?

Doktor Nauk in Architecture (Q16698078) is neither profession nor occupation, therefore

⟨ Doktor Nauk in Architecture (Q16698078)    ⟩ field of this occupation (P425) ⟨ architecture (Q12271)    ⟩

is not allowed. But certainly Doktor Nauk in Architecture (Q16698078) is strongly related to architecture (Q12271) as a field. Any clues how to denote this? -- Gymel (talk) 10:44, 30 January 2015 (UTC)

Similar issue is with hatter (Q1639239)'s relation to hatmaking (Q663375). --Infovarius (talk) 11:47, 4 February 2015 (UTC)

I wouldn't say so:

⟨ hatter (Q1639239)    ⟩ instance of (P31) ⟨ profession (Q28640)    ⟩

,

⟨ hatmaking (Q663375)    ⟩ instance of (P31) ⟨ activity (Q1914636)    ⟩

(where

⟨ activity (Q1914636)    ⟩ subclass of (P279) ⟨ occupation (Q13516667)    ⟩

) and therefore

⟨ hatter (Q1639239)    ⟩ field of this occupation (P425) ⟨ hatmaking (Q663375)    ⟩

is exactly as intended. -- Gymel (talk) 16:36, 4 February 2015 (UTC)

Occupation or profession?

Items for people use P106. This has the English label "occupation".

Sample: Nigel Richards (Q3341367) > occupation > Scrabble player (Q20708269)

If this should be used on such items, should we change the label to "field of this occupation"?

Sample: Scrabble player (Q20708269) > field of this occupation > Scrabble (Q170436)

How should be proceed? --- Jura 14:55, 21 July 2015 (UTC)

Why can't civil servants work in civil service?

I don't have the answer but someone evidently does, otherwise there'd be no protest at Q9844795 (civil servant), stating: "Values of field of this occupation statements should be instances or subclasses of one of the following classes (or of one of their subclasses), but civil service currently isn't:

• industry
• academic discipline
• activity
• knowledge
• area of law".

I don't have a solution but this needs fixing. --Ehitaja (talk) 20:40, 7 January 2019 (UTC)

Inverse property not working well

See discussion at Property talk:P3095#Inverse property not working well. {{u|Sdkb}} ^talk 20:38, 24 June 2020 (UTC)

Constraint conflicts when industry is also an activity

Right now, both of the following claims exist:

1. field of this occupation (P425)property constraint (P2302)conflicts-with constraint (Q21502838)property (P2306)industry (P452)constraint status (P2316)mandatory constraint (Q21502408)
2. practiced by (P3095)property constraint (P2302)inverse constraint (Q21510855)property (P2306)field of this occupation (P425)

This causes a conflict for some items which are instance of (P31)activity (Q1914636) and instance of (P31)industry (Q268592).

For example, candle-maker (Q1739737)field of this occupation (P425)candlemaking (Q29349255). This claim could certainly be omitted from the perspective of candlemaking (Q29349255), since there is already candle-maker (Q1739737)industry (P452)candlemaking (Q29349255) and it seems repetitive, but that would cause a constraint violation on candlemaking (Q29349255)practiced by (P3095)candle-maker (Q1739737) because it would missing the inverse statement. I think removing this last claim from candlemaking (Q29349255) would be a loss of relevant information.

I propose removing the first constraint, so that items could have both field of this occupation (P425) and industry (P452). What do others think? Daask (talk) 13:49, 9 March 2021 (UTC)

@Daask: I am removing candle-maker (Q1739737)industry (P452)candlemaking (Q29349255). As its description states, industry (P452) should have an organization as subject. --GrandEscogriffe (talk) 15:47, 3 February 2023 (UTC)

That should resolve my concern. Thank you! Daask (talk) 16:45, 3 February 2023 (UTC)
