One thing I've noticed about importing multiple data sources is that we may need to model dependencies. For example, when importing the ISO 3166-2:2020 data source, I expect that ISO 3166-1:2020 is already installed.
It may be useful to include a DataSourcePrerequisite table to make it clear that an import needs a particular set of prerequisites.
