You can use the repository to maintain a version history for each
import of a model. These versions are individual objects within the repository and represent
the object’s contents at a specific point in time.
As an administrator, you can manage any number of versions.
When including a model in a configuration, you include a specific version of that model in the configuration. This means that you can control which version of which models are to be published at any point in time.
For example, you can add the approved version of a model in a published configuration while data modelers continue to edit and upload newer version as work in progress (unpublished).
