[CMC] Re: [CESG] Re: [Sois-wir] [SOIS] Proposed way-forward for SOIS

[Adrian J. Hooke]

Chris: I would respectfully point out that at this point time you don't 
have approved charters for *any* of the SOIS work. The fact that you are 
moving rapidly ahead without charters indicates that your contractual 
requirements can clearly tolerate some uncertainty. Surely your contractual 
interests would be far better served by CCSDS consensus than by a rush to 
publication?

My position is unchanged. I want the CESG to evaluate the *whole* SOIS 
situation, all at once, not in piecemeal dribs and drabs. Then I want to 
CESG to formulate a technical recommendation about the whole activity, and 
for the CMC to act accordingly. I see no benefit to issuing a Green Book 
until that holistic assessment is complete.

The Management Council is copied on this exchange. If the ESA delegate 
would like to ask the CESG to forward the SOIS Green Book to the CMC for 
standalone voting with a view towards early publication - without the 
benefit of a CESG review of the rest of the SOIS work - I will of course be 
happy to accommodate that request.

Best regards
Adrian
