Allowed property constraint vs. Required property constraint

I changed the required property constraint - property: object has role to allowed property constraint, because it was requiring object has role for every committee member. It is only necessary if specifying the chair of the committee, as the other people are just ordinary committee members and no specific role is needed to specify.

Number of page constraint

I don't see why number of pages is a necessary constraint for this property. While it is desirable to have the number of pages for a thesis, it is hardly necessary and raising a constraint violation to an essentially unrelated property seems over the top? I have thesis advisors for approx 45k of my 66k theses, and page numbers, atm, for none. DrThneed (talk) 01:21, 24 September 2022 (UTC)

I've nuked that constraint. Makes no sense whatsoever to require this. Schwede66 (talk) 23:46, 21 November 2022 (UTC)
