In both cases 3 database queries are executed:
Query 1:

SELECT dump_id FROM wbqev_identifier_properties
WHERE identifier_pid IN ( ... );

There are 2 open changes (https://gerrit.wikimedia.org/r/#/c/222869, https://gerrit.wikimedia.org/r/#/c/222867) addressing the mentioned issues for ExternalValidation that need to be reviewed. Maybe you guys can have a look?

For all tables except wbq_violations, the issues should be solved. Since wbq_violations was removed in v1, this should not block the deployment.

see https://gerrit.wikimedia.org/r/#/c/221083/

@csteipp, wbqev_dump_information contains a row for each database dump, that was imported. For now, there are only 3 ones. When new databases are integrated for cross-checks, the number will increase, but this table will always just have a few rows.

Html is also needed for $license, since the corresponding item is linked using the EntityIdHtmlLinkFormatter.

Tables names are no longer injected into the database services, but stored as constants. Is this still necessary?

We now created a wiki page: https://www.mediawiki.org/wiki/WikidataQuality

Okay, then Wikidata-Quality should be a better choice.
So far there is no wiki page to link to.
