[Secretariat] [Cesg-all] CCSDS Org & Proc Yellow Book: MOIMS Comments + CESG Chair comments

[Thomas Gannett]

Nestor:

Just a couple of comments in response to the following:

Implementation Conformance Statements

Oh my goodness I feel like we've gone from 0 to 60 with no 
intervening discussion! Yikes! The content of this document should be 
presented during the CCSDS Opening Plenary at San Antonio. It's 
pretty dense by comparison to what we've had before, what with the 
conditional logic involved, expanded notation, footnotes, etc.

As CESG Chair I do not give the go ahead without having feedback from 
the majority of the 28 WG Chairs, because this will heavily affect 
their work (when considering the constrained resource environment, on 
which they are producing the recommended standards).

I am not saying "No ICS" (PICS are already compulsory for protocols), 
but we need probably to find a compromise wrt the "non protocol ICS"

1) The CESG agreed in the spring to changing the PICS requirement to 
an ICS requirement. That agreement was presented at the CMC meeting 
the following week, and modification of the Org&Procs book to include 
the change was the second bullet of the first page of my 
presentation.  I have asked Nick for the draft minutes of the 
meeting, but my recollection is that everyone in the CESG and the CMC 
has already agreed to expanding the PICS requirement to an ICS 
requirement for new projects. (Only the U.S. Congress can pass a law 
and then refuse to accept it.)

2) In response to the "Oh my goodness" comment, the draft CCSDS ICS 
specification is less than half the size of the ISO ICS 
specification, and the requirements are proportionally reduced. The 
statement "It's pretty dense by comparison to what we've had before" 
is true only with respect to the lack a PICS/ICS in most of the 
earlier specifications. The majority of the specifications that have 
included a PICS to date have followed the ISO spec, so if actual PICS 
preparation equals "what we have done before" then the statement is 
wholly incorrect.

Best regards,
Tom
