Daniele, DAI WG members and MOIMS ADs

Please discuss Peter's mail in your WG and with your AD/DAD

The update of the SFDU CA Procedures (630-0-B-1) does not exist as a 
Project in the CWE Framework. No resources have been committed by the 
Agencies to handle it. The next 5 year review is due in May 2018. It is 
clear that if the WG decides to work on it, a Project has to be created 
and resources have to be committed by the Agencies via a CMC poll.

In addition, the WG has to deal with three other potential 5 year review 
Projects (in case the WG decides to review it instead of Reconfirm them)

XFDU BB 5 year review is due since Sept 2013
EAST BB 5 year review is due in June 2015
PAIMS MB 5 year review due in June 2015

Dear Daniele,

I hope all is well with you.  I think that during one of our conversations 
I mentioned that the CESG and the SANA Steering Group (SSG) were looking 
into the somewhat confusing state of our registries in the SANA.  We have 
noted that there are a number of issues and overlaps, particularly in the 
area of organization and person type registries.  The attached 
presentation,  "CCSDS SSG Name & Number Registries", describes the problem 
in significant detail and also spells out how we propose to fix it. 

The presentaiton "CCSDS Registry Re-engineering" is the best current 
description of the form of "what" we propose to do.  What we discovered in 
analyzing the set of CCSDS registries is that there is a set of registries 
that have to do with the "CCSDS enterprise", the agencies, observers, 
affiliates, and the people that they appoint to do certain tasks or that 
have certain roles.  But what we also discovered is that some of these 
registries are well formed, others less so, but that there were overlaps 
and gaps. 

We have a proposed plan for clearing all of this up.

The reason why I am contacting you as DAI WG chair, is the "how" we 
propose to do it.  There are several parts to this that need to have CESG 
review and CMC concurrence.  There is one, in particular, that needs WG 
concurrence.  In the case of your MACAO Blue Book (CCSDS 630x0b1) we wish 
to leverage the very good work that has already been done to define and 
create registries for agencies, and agency sub-elements, and for persons 
with certain roles.  The proposed extensions add some fields for unique 
identifiers and also a mechanism for adding new roles for identified 
persons to allow them to manage other registries than just the MACAO. This 
is a request for your WG to review what we have proposed to see if you can 
concur with the proposed changes which are in the attached mark-up. 

The related changes we propose require some related edits to other 
documents.  I have drafts of all of these prepared and CESG review is just 
awaiting some final adjustments:

SCID BB (CCSDS 320x0b6, CMC / Secretariat)

And the creation of a new one:

Registry Management Policy (SEA/SSG)

What these changes do is to update the SANA Yellow Book to require WGs to 
use (or extend) existing registries where that makes sense, and to tell 
the SANA, in a timely way, when they are creating any new registries or 
proposing changes to existing registries.  The key registries are those 
relating to organizations (agency, observer, affiliate) and to persons 
(with various roles).  The change to the SCID BB is to add a few fields to 
that spec, including unique object identifiers for spacecraft,  and to 
extend the current definitions of Agency Representative, the person 
nominated by an Agency (or Observer) to request changes to the SCID 
registry.  We want to use the general pattern for "Agency Representative" 
as the way to manage all persons who are assigned (one or more) roles by 
their agencies.  Thus one person (AR) might have only one Role (Agency Rep 
for SCID) or they might have more than one Role (Agency Rep for SCID, 
Agency Rep for MACAO,  MACAO RP submitter).

After working over these concepts with the SSG, SANA Operator, and CCSDS 
website team we are convinced that a separate Registry Management Policy 
will be the best way to approach this overall body of work, so I have 
prepared a draft of that too.  That still needs some final changes, so I 
am not sending it now, just the drafts of the SANA, SCID, and MACAO 
documents and the analysis and re-engineering materials.

I think you will find that the proposed changes do not affect any of the 
key fields, contents, or intent of what has already been defined in the 
MACAO.  What they are intended to do it to adopt and extend the existing 
features so that these core enterprise registries can be re-used, and 
extended, by others.  Please review these proposed changes with your WG at 
the earliest opportunity and let us know if there is an issue.  We would 
all prefer to re-use and extend what is there instead of creating a 
parallel set of registries, but we can do that if it is deemed necessary.

Very best regards, Peter
