project repository

a repository that must be dependent on a foundation repository or custom repository that will be managed by the Change Management Facility. A project repository is used to isolate changes from a foundation repository or from a custom repository.

Project repositories provide a development/testing environment for customers who want to implement a formal change management scheme.
