How to express normal professorship?

This property seems to be limited to people holding the special kind of professorship position (chair (Q1363750)   ). How do you express that a person is a "normal" professor at an institution? I tried to find out current practice:

occupation (P106)professor (Q121594) = 5026 statements

position held (P39)professor (Q121594) = 57 statements

occupation (P106)professor (Q121594) and position held (P39)professor (Q121594) = 3 statements

professorship (P803) = 45

professorship (P803) and occupation (P106)professor (Q121594) and = 2

How to express the university and subject domain? -- JakobVoss (talk) 08:39, 9 August 2016 (UTC)

• This question is similar to mine. Could the professorship property be edited to make it clear that it is for named/endowed professorships/chairs, as the examples suggest? Would it be a better practice to add the professor (Q121594) value elsewhere? For example, in an employer (P108) statement with the qualifier position held (P39), where professor (Q121594) would be the qualifier value? -- Uzundzhovets (talk) 23:29, 21 July 2021 (UTC)

Conflict - not all professorships are for university teachers

Currently professorship (P803) has a restriction that it should be for people with occupation (P106) university teacher (Q1622272).

This is a conflict for people who are not university professors but who are an endowed chair (Q1363750).

This property, "professorship', seems to be for professorships and endowed chairs. I think it is correct to combine these concepts.

However, not all chairs are teachers. Some chairs are part of research institutes without any university affiliation or teaching duties.

We can fix this conflict by allowing occupation researcher (Q1650915). Thoughts from others? Blue Rasberry (talk) 13:46, 14 August 2018 (UTC)

I cannot see if multiple constraints will work based on documentation at Template talk:Constraint:Item. Blue Rasberry (talk) 13:52, 14 August 2018 (UTC)

I tried to update this but did not see a change, so I reverted. Blue Rasberry (talk) 13:53, 14 August 2018 (UTC)

Request for deletion

Just like commander of (DEPRECATED) (P598) this property should also be deleted and replaced with position held (P39). See Wikidata:Properties for deletion#Property:P598. /ℇsquilo 20:29, 25 January 2020 (UTC)

Учёное звание? Academic rank?

Probably this property should be splitted into ru"учёное звание" ("academic rank") and en"professorship" (ru"кафедра"?). --Infovarius (talk) 13:25, 7 May 2020 (UTC)
