[Moims-dai] Suggested Information Package Definition

Thanks for your clarification.  I think you've made a significant 
improvement by creating situational definitions for these three. I hope 
we can form a consensus around them.

I was at first concerned about the expression 'traceable to' in Item 
3. Because it better reflects the activity needed to create a DIP, I 
preferred the construction 'derived from' instead of 'traceable to' but 
I'm willing to drop that quibble. I had thought the intention of 
'traceable to' to be that a DIP would be required to have clear or open 
text identifying the detailed sources and methods that generated it's 
outputs(or payload or intended Content or PDI). That  might in some 
cases be a potential breach of privacy or security considerations.  I 
realize now that that was a misinterpretation.

Even if others might be lead down the same path, I'm not sure if we want 
to clarify this intention.   Internally, of course, the Archive would 
need to maintain traceability to the sources and (algorithms/processes?) 
used to create a particular DIP. But the DIP would need only to contain 
a unique (trans)action identifier, probably including a timestamp, which 
could be used by some authorized ("cleared") agent to perform the 
necessary traceback research should the need arise.  It leads to an 
interesting question of provenance, which, for the DIP would be a 
composition of all of the aforementioned sources and processes as 
collected under the action identifier even if only the action identifier 
would be available to the DIP recipient.
