Using Library Services with a BEA Repository
When you use a BEA Repository, you have the option 
  of enabling library services. Library services provide additional content management 
  tools, including the abilities to version content and to use a Content Workspace 
  that automatically tracks content that is in progress. 
For a complete overview and additional documentation 
  on using library services with content management, se the  
  Content Management Guide on BEA's edocs webpage.
