• Content Service - Storage and retrieval of content (text/binary)
  
• Node Handles and Store Protocols - Approach for identifying Nodes and Stores within a Repository
  
• Versioning - Support a basic version and locking model, but potentially use Subversion or comply with JSR-170 Level 2 (Optional)
  
• Search - Support search in a Google-style search and JSR-170 XPath search
  
• Search Documentation - A description of the search syntax
  
• Classification - Provide hierarchical classifications and the old enum support
  
• Actions and Rules - Provide services to allow actions to be executed manually and automatically, using rules, within a Repository.
  

Standard Interfaces
