Hey, since I haven't taken up adding them since Wikidata:Project chat/Archive/2019/05#Does Wikidata lack a Quality mindset? Sometimes it feels more like a playground for python exercises...? I wanted to ask you if you still oppose adding them? As I tried to point out, I didn't add them as an end in itself, but prefer to have references for the statements I've added them to, mainly place of birth (P19), place of death (P20), sex or gender (P21), occupation (P106), and consider ULAN to be a professional, reliable and itself sourced tertiary source.
In addition, for most cases I don't see much chance for getting much different sources for that data. Note that for that data there mostly isn't a source in Wikipedia (at least English and German versions) and it is often enough disputable.
I manually work on lists like c:Category:Creator templates with Wikidata link: mismatching birthdate, WD:WikiProject sum of all paintings/Creators same name or WD:Database reports/Complex constraint violations/P245#Female according to Wikidata, male according to ULAN where sources are key. I add a lot of sources manually which is tedious work. The automatically added references ease it in my eyes.
Thanks for your reply, m.
