<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The updated version of the Reference Model focuses on making the material associated with these FRs as complete and correct as possible, including (but not limited to) response from review comments on the previous version provided by Wolfgang,
having a different section for each of the Functional Resource Strata, and graphics that are consistent with the graphical conventions for at least all of the aforementioned Tier-1 FRs.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As you may know, the draft Reference Model also contains material on many other functional resources that exists at various levels of maturity, from mere placeholders to well-developed definitions only lacking in the definition of the specific
parameters, events, and directives (PEDs) that are registered in the SAN FR registry. In order to help the subject matter experts focus their review on the FRs that are specifically included in the SANA Candidate FR registry, the plan is to make available
to those reviewers a “draft Red Book” version (CCSDS 902.x-R-0.4) that addresses only those FR Sets and FRs that are in the SANA Candidate FR registry. In the next few weeks, I will produce that draft Red Book by trimming out the non-applicable material from
the White Book. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My intention is to use the material from the White Book version (which has no formal CCSDS standing but has informally been used by CCSDS to document “working group-internal” material) as a source for future updates of the draft Red Book
as SANA FR definitions are created for and added to the SANA Candidate FR registry and (eventually) graduated to the SANA Approved FR registry. When some TBD set of FR definitions has been graduated to the SANA Approved FR registry, then the version of the
draft Red Book in existence at that time could undergo a CCSDS Agency Red Book review and become the first issue of the FR Reference Model Magenta Book.
