Constraint as qualifier only is problematic

There are times when this property needs to be used as a qualifier in a reference, so the constraint that this should only be used as a qualifier to the item is a problem. For instance, if someone is mentioned with an age in a census record which would support a year of birth, that needs to be against the reference not the birth event.  — billinghurst sDrewth 22:59, 4 March 2018 (UTC)

@Pasleim: it would appear you initially applied the constraint. Is there an alternative way to label this to indicate this duality?  — billinghurst sDrewth 23:02, 4 March 2018 (UTC)

Example at Q18912183  — billinghurst sDrewth 23:03, 4 March 2018 (UTC)

It was proposed as a qualifier. Maybe with the new qualifier constraint scope we can specify that it can also be used in references.

removed "allowed units constraint"

I have removed the constraint "allowed units constraint" as it doesn't make sense in the remainder of the context of the property as shows. Firstly there is a maximum value of 130, so that presumes that years old is the constraint unless otherwise specific, and doesn't make sense for anything else. It was also showing a constraint error where used, and yet the value shows that a unit is optional. Please can we resolve these issues prior to adding the constraint back.  — billinghurst sDrewth 14:21, 28 April 2018 (UTC)

• In your view, what should the unit be? Any? None? Years old?

Bot to add at date of death

Can we have a bot add the value at date of death for all humans, where we have precise birth and death dates? It would be valuable in disambiguating people without doing any math. RAN (talk) 00:44, 2 May 2023 (UTC)
