Hi everyone,
As a data quality addict, I've been investigating the coverage of external identifiers linked to Wikidata items about people.
Given the numbers on SQID [1] and some SPARQL queries [2, 3], it seems that even the second most used ID (VIAF) only covers *25%* of people items circa. Then, there is a long tail of IDs that are barely used at all.
So here is my question: *which external identifiers deserve an effort to achieve exhaustive coverage?*
I've been doing this for painters. See https://www.wikidata.org/wiki/Wikidata:WikiProject_sum_of_all_paintings/Crea... and https://www.wikidata.org/wiki/Wikidata:WikiProject_sum_of_all_paintings/Crea... .
