<p class="MsoNormal">Thank you for your prompt reply. I appreciate the insights and clarifications you have provided. I can also appreciate the frustration with OMG. Nonetheless, I think it is important for liaisons to consult with CESG or other parties within
CCSDS as needed to achieve a consensus as to how to proceed and/or respond - to me this seems a vital aspect of the liaison role. For example, given the situation, should CCSDS continue to develop an informational overlap report rather than work on analysis
re incorporation of what OMG proposes to produce into MO services? I don't know the answer but it strikes me that a conversation/consensus development at the level of CESG would help in determining that.

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">Dear Erik,</span>
<br>
<span style="font-size:10.0pt;font-family:"Arial",sans-serif">I am on leave in these days, so I will (try and) provide an initial clarification to your point(s), while these will be more comprehensively discussed during the Telecon – I assume your DAD will
be attending.</span> <br>
<span style="font-size:10.0pt;font-family:"Arial",sans-serif">Basically, the issue had been indeed addressed at the CESG Meeting in Gaithersburg, where MOIMS AD presented the whole issue in his Area Report, and the CESG concluded that ESA, CNES, and DLR members
of the SM&C WG shall produce a Technical Note containing the analysis of the overlap. That TN shall be used by the OMG Liaison to substantiate the discussion with OMG.</span>
<br>
<span style="font-size:10.0pt;font-family:"Arial",sans-serif">All that is documented in the CESG Meeting’s MoM.
</span><br>
<span style="font-size:10.0pt;font-family:"Arial",sans-serif">Mario’s intention in his e-mail was only to give a head-up to OMG that this analysis was coming, knowing that the process of producing the TN, and then having it reviewed first by CESG, then by CMC
will take a certain time. </span><br>
<span style="font-size:10.0pt;font-family:"Arial",sans-serif">However OMG decided to proceed, for the reasons that you can find in their e-mail, without waiting for the TN.
</span><br>
<span style="font-size:10.0pt;font-family:"Arial",sans-serif">No doubts about the usefulness of having a CCSDS – OMG liaison, but I think Mario’s concern was only about the fact that his head-up had not been considered. </span>
<br>
<span style="font-size:10.0pt;font-family:"Arial",sans-serif">Meanwhile , the TN has been produced and has been distributed to CESG for comments, and for discussion at the mid-term Telecon. At the same time, I’ve sent the TN for info to the CMC, and informed
about the ongoing assessment by CESG, This will be followed by assessment by CMC.</span>
<br>
<span style="font-size:10.0pt;font-family:"Arial",sans-serif"> Given the fact the OMG already proceeded with the C2MS, all the above may look superseded by facts. Still, for the sake of coherency and for completeness of information, the OMG should receive such
TN, in case there will be consensus on that within CCSDS.</span> <br>
<span style="font-size:10.0pt;font-family:"Arial",sans-serif">I will address this further at the CESG Telecon.</span>

<p style="margin:0in;margin-bottom:.0001pt"><span style="font-family:"Georgia",serif;color:#004080">There may in fact be issues between MOIMS SM+C WG and OMG SDTF. But CCSDS is not just MOIMS SM+C. My experience is that I have found OMG GEMS standard to
be quite complimentary to the work of the CSS Area and therefore have found the liaison with OMG to be useful. To me it is objectionable for the CCSDS liaison to question the usefulness of the liaison prior to consulting with the rest of CCSDS. From the
email exchange it sounds like OMG provided due process relative to its rules and governance. As such it can be argued that a strategy session inside CCSDS should have occurred to assess the situation, provide an analysis of alternatives and consider other
courses of action. For example, perhaps CCSDS could have considered the opportunities brought forward by their RFC process rather than unilaterally (without any consultation at the level of CESG as far as I can tell), calling the liaison into question.

<br>
<span style="font-family:"Arial",sans-serif"><br>
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!
</span><br>
<span style="font-family:"Arial",sans-serif"><br>
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</span>
<br>
<span style="font-family:"Arial",sans-serif"><br>
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.</span>

<p style="margin:0in;margin-bottom:.0001pt"><span style="font-size:11.0pt;color:blue"> 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. </span><o:p></o:p></p>

<p style="margin:0in;margin-bottom:.0001pt"><span style="font-family:"Arial",sans-serif">Dear Steve,</span>
<span style="font-family:"Arial",sans-serif"><br>
<br>
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):</span>
<b><span style="font-family:"Arial",sans-serif"><br>
<br>
Satellite Command & Control Message Specification (C2MS).</span></b> <span style="font-family:"Arial",sans-serif">
<br>
<br>
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.
<br>
<br>
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.</span>
<span style="font-family:"Arial",sans-serif"><br>
