[Domain] Review semantic version validation rules #75

Closed wwerner closed 4 years ago

wwerner commented 5 years ago

Currently, a schema version of maj.min+1.patch or maj+1.min.patch cannot be created if preceeded by maj.min.patch in status Draft. A version of maj.min.patch+1 can be created.

It is not entirely clear to me what the actual business rules encompassing previousVersion, currentVersion and status should be.
