Qualifying student types

We have rich data on American colleges and universities in the Integrated Postsecondary Education Data System (Q6042926). I've experimented with qualifying students count (P2196) using applies to part (P518). For instance, Valparaiso University (Q186047) has recent students count numbers at http://nces.ed.gov/collegenavigator/?id=152600#enrolmt, and so I added those values qualified by applies to part (P518):undergraduate student (Q21094885) and applies to part (P518):graduate student (Q21094889), plus point in time (P585). I'd love to hear opinions on whether this is an appropriate solution, and if so, whether you support extending qualification to student types like full-time (Q1198527) or race/ethnicity or distance education, for instance.

• •  Support the idea of partitioning by undergraduate student (Q21094885) and graduate student (Q21094889). I had the same idea for Institute of Mathematics and Statistics, University of São Paulo (Q10302895). Regarding the extension to other classifications, I'm less enthusiastic because it would make it harder to programmatically generate an accurate total count since there would be potential overlaps between each part. --Pedropaulovc (talk) 17:42, 2 November 2019 (UTC)

Unit Constraints

Can we get the unit constraints for student count in order? It's currently empty, leading tools to warn. @User:Laboramus --YaguraStation (talk) 22:20, 3 March 2019 (UTC)

Missing point in time (P585) qualifier

Please see Wikidata:Bot_requests#Year-qualifier_for_"students_count"_(P2196)_values. --- Jura 06:36, 29 November 2020 (UTC)

Should qualifier time period (P2348) be allowed too ?

Seems like a lot of french schools were imported using a qualifier time period (P2348) instead of the required qualifier point in time (P585), were time period is something like academic year 2022-2023 in France (Q119628110) : a custom range of dates for an academic year, spanning over two calendar years. There are around 31557 qualifiers with that value at the moment (see d:Special:WhatLinksHere/Q119628110), and as many warnings "required qualifier constraint (Q21510856)". IMHO, that qualifier time period (P2348) should probably also be allowed as an alternative to point in time (P585) when using any instance of academic year (Q915466) as value, as it does seem quite relevant. --FoeNyx (talk) 18:29, 21 October 2023 (UTC)
