Hi Richard,
I started importing New York Times obituaries in Wikidata! I'm very happy with the result so far, I finished the 2022 year, and I'm planning in the upcoming days and weeks to do the previous years (2021, 2020, etc).
Here is a Sparql query to see all the obituaries for 2022:
I will improve the query to get the date of death of the person, and to do the difference between publication date and date of death (so we can track the discrepencies).
As you can see, so far less than a dozen are associated with their main subject. Tonight I will run a script to do the association (doing a matching based on the name and the date of death), which will probably work for a majority of the cases. But probably the rest would have to be manual. Will see.
I keep you updated.
