Subject: RE: The Hal/David model


I have updated the domain model as best I can with the various emails,
glossary, pdfs, etc. that are available.  I don't yet have a usable copy of
Visio, so the diagram will come from togetherJ for the near future.

This is an imperfect job as I was a bit overwhelmed by the glossary and all
the discussions on terminology differences.  I started bottom-up (what
glossary terms are required) rather than try to fit all the glossary terms
in the diagram.  

I have liberally and flagrantly infringed copyrights by copying some
material from the mailing list(s) and the glossary.  I also copied from the
glossary rather than refering to it, so that reviewers could combine all
their comments together.   I also added issues where definitions seemed
vague/confusing/etc.

This is complete in that every item and major relationship listed in the
class diagram has a glossary entry.   

Process going forward: I expect that once we come to agreement on what we
mean by terms, we can then push them back to the glossary.  Please provide
plenty of feedback to the group on this.

Suggestion for the use case chair and subcommittee: Very soon we start only
allowing conversations about terms that are in the glossary/domain model.  I
have been scanning various e-mails and notice many different synonyms, which
I (and I'm sure other readers) would find confusing.  I suggest that the set
of requirements we are now balloting is a candidate for this.  Terms like
subject, policy-based disclosure, subject security attributes, parties,
disclosure,  run-time, sharing, etc. are not currently in the domain model,
nor in the glossary.  One person's run-time is another persons compile-time,
etc.  Let's define these terms or not use them at all.
