Based on the SQL requests results in #244 and the table in this PR preview, there are some inconsistencies.

Data inconsistencies

Nullable columns

The database fields that are nullable in DDLs but don't have any NULL values in the database

• identifier
• ingestion_type
• provider (there is an index on it, in combination with `foreign_identifier)
• source
• foreign_identifier (there is an index on it, in combination with provider)
• foreign_landing_url
• license (no data in the linked issue, but there should be no row without a license)
• license_version
