Options:

Use JCR node hierarchy

• One "implicit" hierarchy
• Would probably resemble URL structure - REST-like thinking (one URI for each resource)
• Additional hierarchies possible:
  • Via separate node hierarchies with references
  • Via shared nodes (JSR 283)
    

Advantages:

• Simple
• Straightforward
• Better performance
  

Use flat storage with artificial hierarchy

• Either XML stored in a property (like now)
• Or separate node hierarchy:
  • Via references to the content nodes
  • Via shared nodes (JSR 283)
    

Advantages:

• More flexibility re. content model (e.g. translations with common parent node) without constraining the URI space
