DescriptionEdit

The description's usage of "subject" is problematic: it can be misinterpreted to mean a field of study (e.g. linguistics). Already in Italian it is translated as "persona che ha studiato una disciplina". Therefore I changed it to "this person"; if someone knows a better wording, feel free to change.

student (P802) has a restriction that start time (P580) is not allowed as a qualifiers. I would like to see for student (P802) and student of (P1066)

I am adding www.swedishmusicalheritage.com as Swedish Musical Heritage composer ID (P4607) and are trying to describe Sigurd von Koch (Q5916637) using the article koch-sigurd-von - Salgo60 (talk) 05:38, 13 December 2017 (UTC)

Inconsistency about notabilityEdit

Hi,

There is an inconsistency about notability in these properties :

  • P1066 says « person who has taught this person » (without notability criteria)
  • P802 says « notable student(s) of an individual » (with notability criteria)

As there is a inverse constraint (Q21510855), the inconsistency is very problematic. Can I remove the « notable » wording?

Cdlt, VIGNERON (talk) 07:32, 25 April 2018 (UTC)

I’ve just seen the inverse constraint and I think it’s hardly workable to systematically duplicate student and student of. I support either to remove the inverse constraint or to delete P802 altogether. I frequently document student-teacher relationship and use P1066 exclusively (as student <= teacher is usually a much more significant relationship than teacher => student and it’s fairly easy to retrieve the reverse relationship with SPARQL).
