- Efficiency/Performace
- Update of objects
- Handle & Links Symantics
- DataObject as a base class
    - Is it more than a common base class?
    - It is reference counted.
    - Enables introspection.
    
- Can we do DataHandle<int>? Yes.

- Link is a persistable pointer (not a range)
    - What is a reference to container & a key
    - DataReference use a DataHandle?
        Could be a pointer, but need to be able to
            recover DataHandle for output.

- Persistency? - I/O section

- Registration of object in Whiteboard is contention
    - it is possible, but scheduler contention larger.

- Updated is not a good idea.
    - Can we live without it?

- What is the impact on the Archive Event Store?

- semantics of DataHandles
    - Immutable after insertion
    - Might as well move objects into store
        (writer takes T&&)

- Charles and Gerhard will bring proposals tomorrow.

- Check codes to make sure DataHandles are sufficient.
