Item requires statement constraints

This property has a lot of constraints which are not related to the ISO codes which were added back in the early days of Wikidata. I've removed some of the constraints which had a lot of constraint violations (they haven't been fixed in five years, so they can't be very useful constraints). Any reason why we shouldn't remove the others? - Nikki (talk) 14:20, 11 June 2018 (UTC)

• Maybe there is a more suitable property for them (one that is just used on sovereign states). The approach works fairly well for US states. See here. It also ensure that these don't disappear.
  --- Jura 14:45, 11 June 2018 (UTC)

It doesn't prevent them from disappearing, every single one of the constraints here has violations. I don't see any evidence that anyone actually cares about these constraints (nobody appears to have even noticed that the report has been completely broken for 6 weeks), so I'm going to go ahead and remove them. If someone is interested in tracking the completeness of items, it's easy to make a Listeria-based report. - Nikki (talk) 10:39, 11 August 2018 (UTC)

No value with preferred rank ?

If there is an end date on a value, should we also a "novalue" claim with preferred rank (and start date)? sample. Obviously, unless there is a new value that would have it.
--- Jura 14:45, 11 June 2018 (UTC)

• I added two samples illustrating no value claims (one for an existing entity: JT, another for one that no longer exists: AI). AI also illustrates that the same code was later reassigned. Preferred rank can only be seen on the actual items: Q1450765#P297, Q131008#P297. --- Jura 10:35, 23 September 2020 (UTC)
