Attached please find the updated RASIM Green Book.  Within it I have made
the necessary changes to reflect the feedback from the CESG review. Would
you please clean up Figure 1-1 as Keith requested since I do not have the
source for that.  You will also have to clean up the figure reference
changes caused by the inclusion of two new figures, as requested.

Once this is done I think the document is ready for the CMC poll.  Please
consider this a formal request to initiate that poll once these editorial
changes are made.

Thanks and best wishes for a properous New Year.

A note has been added to Section 1.2 Scope dealing with this request and
indicating that there is no companion BB nor MB due to lack of agency
resources.  It also states that the document is descriptive, provided for
information, and not binding on CCSDS standards nor working groups.

The Introduction and Scope sections clearly state what the document is.
These sections do not describe at length all of the things that the
document is not.  To do so, in any consistent way across all CCSDS
documents, would turn all of their Introduction and Scope sections into
some some of encyclopedia of what they are not.  Clearly we would not want
to do this for all CCSDS documents so I have chosen to take the more
appropriate path that we use elsewhere here as well.

The reference to the CCSDS SM spec, 910.11, has been added and the figure
and table relating to Service Agreement have been changed to instead
reference the Service Package.  The ServicePackageRequest (fig 4-5 from
910.11) has been included along with a portion of a table defining the
data and meta-data.  This is now exactly aligned with 910.11.

As requested, two new figures have been added to Sec 1 (class diagram of
information management architecture elements) and to Sec 2 (class diagram
of meta model, domain model, information model relationships).

Sec 6 has been updated in a fashion similar to that used in Sec 1.2,
indicating that while the document was intended to lay down a foundation
for future work that work has been postponed due to lack of agency

Please see previous note re Introduction and Scope.  The document clearly
states that it is about informaiton models.  It does not say that it is
not about space links, but that should be obvious.  Since we clearly would
not want to make extensive statements about all that any given document is
not for all CCSDS documents I have chosen to take the more appropriate
path that we use elsewhere here as well.

See previous note re changes to Fig 2-6 and the related text that now
directly references 910.11.

The figure will be updated.
