[Ccsds-omg-liaison] FW: CCSDS-OMG Liaison: Satellite Command & Control Message Specification (C2MS)

Thu Jun 28 08:26:45 UTC 2018

Dear Steve,

it is very disappointing that the OMG, after a strenuous discussion of 
1.25 hours on my 10 line email, has decided to move forward without 
waiting for the analysis in the Technical Note that was announced and is 
under finalisation. The motivation adduced for the decision, i.e. that "
the consensus of the Space DTF and OMG AB that the note below was your 
position ...", is offensive and reductionist: I deliberatively did not 
participate in the WG discussion to avoid influencing. The outcome of the 
discussion in the WG, which I reported in my email, is that 3 space 
agencies out of 4 that are active in the WG, i.e. 75%, had identified 
notable overlaps: it is not my opinion! 

Thanks for the offer to provide/clarify the OMG’s P&Ps and processes, but 
there is no need. I will consult with the CCSDS Engineering Steering Group 
and question the usefulness of a technical liaison between OMG and CCSDS 
in these conditions

I will still provide you with the technical note, once available. Please 
note that the technical note is also a collective work supported by the 
same 3 agencies and it is not even led by ESA.

Regards,

__Mario

Mario – 

            I rec’d a bounce back that you did not receive the below email 
despite the same address.

Mario – 

            I wanted to be the first to notify you of the results of the 
Object Management Group’s (OMG) Space Domain Task Force (DTF) and 
Architecture Board (AB) decisions.  Your note created a great deal of 
conversation, dialog and debate, since receipt while here in Boston at 
OMG’s Quarterly Technical Committee (TC). 

            Two days ago during the Space DTF, they spent an hour 
discussing your email to determine whether or not to forward onto the AB 
for vote.  The pro’s and con’s were discussed with the largest concern 
being if the AB accepted the concerns in your email below and sided with 
you, the MCMS RFC would be dead and never allowed to become an RFP. 
Therefore the Space DTF’s decision to vote to send to the AB would be very 
risky and all avenues and scenarios possible were discussed.  In the end, 
the MCMS RFC was voted to move to the AB. Please note, on Monday June 18th
, I sent your email below to the AB for their review per the AB Chairman’s 
request even though it was sent to me versus the formal process and being 
7 days late to the 4 week rule.  This allowed all the AB members to review 
all the documentation before meeting yesterday afternoon and discussed it 
at the AB Plenary on the 18th.

            Today during the AB, they had a lengthy and painful discussion 
that lasted 1.25 hours on MCMS and your email.  Per OMG’s Policies and 
Procedures (P&P) your email was reviewed, discussed, debated and 
alternatives explored.  I want to let you know, that in 1.5 hours 
preceding the MCMS discussion, 4 RFCs and 2 RFPs were reviewed.  A motion 
was made and seconded, discussion followed, amendment made on intellectual 
property, and voted on.  Before the vote, a dissenting opinion was raised 
and explored/discussed when a AB Member called the question for vote. 
Eight (8) votes were for the motion, one (1) against and 1 abstained and 
the motioned passed to approve the MCMS RFC. 

            I, the Space DTF, and OMG value your, ESA’s and CCSDS’s inputs 
and would like to have a closer collaboration throughout OMG’s and CCSDS 
processes.  It was the consensus of the Space DTF and OMG AB that the note 
below was your position and possibly that of ESA’s.  Your email was the 
only note of contention received.  If I need to clarify OMG’s P&Ps and 
processes, I can provide and or put you in touch with the right contacts 
to answer your, ESA, CNES or DLA’s questions.  Our next meeting will be in 
September in Ottawa Canada.  You can find out more at www.omg.org. 

Take Care -

Specification (C2MS)

Dear Steve, 

in the context of the CCSDS-OMG liaison I would like to inform you that 
during the last CCSDS Technical Meetings in Gaithersburg (09-13 April 
2018) reservations had been raised on the proposed OMG standard (RFC): 

Satellite Command & Control Message Specification (C2MS). 

In particular, three space agencies via their members in the CCSDS 
Spacecraft & Control Working Group have identified notable overlaps 
between the above perspective document and the on-going work of the 
working group on Mission Operations (MO) Services. These Space Agencies 
(CNES - French Space Agency, DLR - German Space Agency, and ESA - European 
Space Agency) are producing a Technical Note to substantiate the overlap, 
which will be available in the second half of June. 

Clearly, in the spirit of the liaison, both CCSDS and OMG should strive to 
avoid overlaps and duplications, in favour of reciprocally adopting 
relevant standards, as already done for instance by the CCSDS with the 
adoption of the OMG XTCE standard. 

Sincerely, 

Mario Merri 
CCSDS liaison to OMG
