Re: [Wikidata] Dead or alive ? Probably dead

We have also other properties on Wikidata to refine partial knowledge about the chronology of a life : https://www.wikidata.org/wiki/Property:P1317 – floruit https://www.wikidata.org/wiki/Property:P2032 / https://www.wikidata.org/wiki/Property:P2031 — floruit begin and end that may overlap with

Re: [Wikidata] Dead or alive ? Probably dead

I think if we wanted to do this with a bot, we should go through the usual bot approval process, and discuss this on wiki? But in general, as said, adding unknown value to people who are very very sure to be dead sounds like a good idea ( https://www.wikidata.org/wiki/Q28 ) On Thu, Sep 19,

Re: [Wikidata] Dead or alive ? Probably dead

On FactGrid we created two properties for this (maybe clever, maybe daft): P290 and P291 for estimates (or for knowledge) of an earliest and latest point in the life span. The necessity is here that we have loads of people with just a single data point like "studied in Jena in 1776" or

Re: [Wikidata] Dead or alive ? Probably dead

"unknown value" was made for exactly that use case - a person that has died, but we don't know when. I would just add that on the "date of death" property. On Sat, Sep 7, 2019 at 2:25 AM Thomas Douillard wrote: > We have already a qualifier for this kind of stuffs, I think : P887 >

Re: [Wikidata] Dead or alive ? Probably dead
