The following two standard repositories store the data that ATG Content Administration requires:
VersionManagerRepository
The /atg/epub/version/VersionManagerRepository is a GSARepository that stores the development lines (branches, workspaces, and snapshots) and asset version metadata used by the /atg/epub/VersionManagerService, the default VersionManager provided with ATG Content Administration.
For more information on versioning concepts and terms, see Versioning Assets.
PublishingRepository
The /atg/epub/PublishingRepository is a GSARepository that stores the items required by the Business Control Center: processes, projects, workflows, and so on.
To secure access to its items, the PublishingRepository has a secured repository configured on top. The secured repository is located in Nucleus at /atg/epub/SecuredPublishingRepository. For information on configuring security of the PublishingRepository, see the chapter Managing User Access and Security.
Note the following about the PublishingRepository:
- If you export the items in the - /atg/epub/PublishingRepositoryfor any reason before re-importing the items, for example when rebuilding your content development environment, you must manually remove the following items from the data file:- All workflow-related items. That is, all items of types defined in: - <ATG11dir>/Publishing/base/config/atg/epub/workflow.xml
- All process- and project-related items. That is, all items of type - processand- projectand all child items defined in:- <ATG11dir>/Publishing/base/config/atg/epub/publishing.xml
 
- These items should not be re-imported into the - PublishingRepository.
- Each - processitem in the- /atg/epub/PublishingRepositorystores a set of- processTaskInfoitems in its- taskInfosproperty. These items store information about the project’s workflow tasks—for example, the segment name for each task. After a project completes its workflow, its- processTaskInfoitems are no longer needed and should be purged. This is an important clean-up task, as performance can be affected if the number of items exceeds its- item-cache-size.
- The - /atg/epub/workflow/process/TaskInfoPurgercomponent is a service that periodically purges the- processTaskInfoitems of completed projects. By default it is scheduled to run every day at 1:00 a.m. You can change this schedule so it better reflects how often Business Control Center users create projects, for example every 6 hours. To do so, edit the- TaskInfoPurger.scheduleproperty.
