Dear CMC members

herewith I would like to address with you an issue that I have never seen 
in the past 15 years (11 as CESG Co-Chair and 4 as CESG chair)

Notwithstanding the CESG Chair recommendation (see mail below) , the SEA 
AD has decided unilaterally to deliver a CCSDS response to the OMG RFI on 
Vocabularies, Glossaries for the Spacecraft Ground Systems Domain (see 
mail below).

The following is noted
SEA AD has broken the formal steps foreseen in the Proc & Org YB when 
consensus is not achieved (see the CESG Chair mail below). There were 
several mails from the CESG Chair warning him on the need of further 
SEA AD has proceeded with the RFI submission without having the authority 
to do that.
SEA AD has given higher priority to the OMG RFI due date (28th Feb 2017) 
than the achievement of consensus within the CESG and CMC.
SEA AD has ignored that this type of requests has to be carried out by the 
nominated liaison to OMG (i.e,. MOIMS AD)
SEA AD is also giving the option to convert this as a NASA response to the 
RFI. This mixes CCSDS and Agency interests (I accept  that at the end 
could be the same). This is particular weird coming from the SEA AD who is 
one of the most ferocious defenders of CESG ADs role without wearing the 
"Agency hat"
SEA AD did not warn the CESG of his intentions before the RFI due date, 
This is understandable, because he would have received the same CESG Chair 

As CESG Chair I will bring this topic to the next CMC meeting. I will also 
propose some updates to the YB to avoid this type of behaviour in the 


For the sake of completeness I attach below the main goal of this RFI
The RFI was generated based on a request from US Air Force attendees to 
establish a common terminology for ground system operations personnel.  
The SDTF is trying to help them determine what is already established as 
?standard? terminology from various industry and government sources.  The 
results of the RFI will help them refine the scope of what they are asking 
for and they could possibly adopt one of the inputs without any further 
action by the SDTF.

As CESG Chair I am against to respond to the OMG RFI under pressure
I do not like this type of private mails without involving our liaison.
If OMG is really interested in our work, they can delay the FRI due date 
by 1 or 2 months. 
Or they can go ahead without us. The world will not break apart, unless 
there are other type of interests (not known to me)
As there is no consensus, we must wait until the issue  is discussed at 
CESG and CMC level. 
And the exchange of info shall be via the liaison. Please tell the US OMG 
colleagues to follow the liaison signed document

Nestor & Mario,
In the interest of full disclosure, I wanted you to be aware that I sent 
in the attached response to the OMG ontology RFI.  As I said at the 
outset, I think it is important that the OMG be made aware of the work 
that we have done, and are doing, in CCSDS. 
I was made aware that the window for RFI submissions had closed, but that 
they were really interested in having the CCSDS input to consider within 
their process.  I chose to provide them that input instead of standing by 
silently and missing the opportunity. 
If you continue to think this is not acceptable we can treat it as a NASA 
submission, since NASA is an OMG member.
Regards, Peter

Dear OMG,
As you are aware the CCSDS is an open, consensus-based, international 
standards organization that develops space standards.  All of these 
materials are copyright CCSDS, and they are in the public domain, openly 
and freely published on the web. 
The CCSDS Glossary is a compendium of terms that have been formally 
defined in the various standards that we have published starting in the 
early 1980's.  As such it is not an ontology, but it does include a very 
broad range of carefully defined and reviewed terms that cover space 
communications, from the physical layer up through the applications 
layers.  The XML version of that is attached.  The source registry is at 
Since your expressly stated interest is in ground systems & ground 
stations I am also sending you a CCSDS technical note and related 
presentation. This was developed by one of our staffers and it describes 
what are called Functional Resources.  This is the term we use to describe 
the set of abstract functional entities that perform ground station comm 
processing for forward, return, and radiometric tracking services.  Given 
your focus on this subject we think you may find it of interest, along 
with the related standards that have been developed for cross support and 
those that are in development for planning, scheduling, configuring and 
monitoring ground stations.
We understand that the period for RFI submissions has closed, but we think 
it is important for you to have access to this information for your 
deliberations.  Just so you are aware, if there is interest in any sort of 
collaborative ontology effort with CCSDS we will have to arrange that 
through the existing OMG ? CCSDS Liaison route.
Regards, Peter Shames

We must recognize the strong and undeniable influence that our language 
exerts on our ways of thinking and, in fact, delimits the abstract space 
in which we can formulate - give form to - our thoughts.
