Exactly. A different packaging would mean it’s a different release. Countries, continents etc are all information that should be assigned to the release and based on these the editor will need to identfiy it before assigning the Disc ID - or add a new release if it’s not in the database.
The necessary data to identify it correctly needs to be there before the ID is added. Otherwise the ID will be worthless.
This is why we have to make sure that the editor has picked the correct release.
That does sound fairly unlikely, but then again I simply buy CDs and never sell them.
In case I would need to find another copy, all the necessary information would ideally be in the release’s entry…
As different cover art would result in a different release, the use will probably be rather limited.
