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/Cre…
and
