I guess this question for me is how do we do this in practice? How do we
make sure Wikidata stays up to date/synced with external databases we think
are important?

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?*
Looking forward to your valuable feedback.
Cheers,
Marco
