[DDI-ADG] draft Aggregate Change Proposal

[Katherine McNeill-Harman]

(for those of you who weren't in last week's meeting, we're trying to 
organize the Aggregate data proposal quickly to prepare for the Ann Arbor 
meeting; this is a draft of part of that proposal)

Attached is a first draft of the Aggregate Change Proposal; please send 
comments/feedback to the group (and feel free to add to it and send out new 
versions).  It is missing the use cases (which J will insert), but in 
writing it I realized I also have the following specific questions for the 
group:

1) In geography proposal, J had section for known issues (that is, things 
that we know are problems with the proposal, that we want to make 
clear).  Do we have any of these?

2) How is the description of the logical structure, specifically the 
attributes?  Do we need more detail (and if so, what)?

3) The description of the modules in the physical structure is fairly 
general, without references to/descriptions of specific elements.  Do 
people feel more detail is needed?  If so, I'm still not crystal clear of 
exactly the role of all elements w/in the different modules (w/o the notes 
being finalized, found myself confused), therefore feel free to expand 
where you think it would be useful.

Kate
