The DELETE REPOSITORY command deletes all the elements in a
    repository, any relationships between elements in the repository
    or elements in other repositories, and the repository itself.

    Unless you change repository protection, only the owner of a
    repository or the system manager can delete a CDO repository.

    You cannot delete a repository if it contains an element that is
    used by another element in a different repository.

                                 CAUTION

       Before you delete a repository, be sure your elements do not
       have relationships to other elements in other repositories.
       Check to make sure you have not stored user-created files in
       the repository.
