[CESG] Approval of CCSDS Document Project - All Recipients Please Review

Dear Mario,

Based on the description in your email I see no issues with the proposal.   In general, to the best of my understanding, prototyping is to prove the technical feasibility of recommendation with respect to suitability for implementation.   Moving material around in blue books should not affect this in any material sense.  For future traceability/posterity perhaps the WG may wish to keep in mind the potential for a minor editorial note for the current prototype test report if it senses that any potential for confusion emerges.

Best regards,

Dear CESG chair and CESG colleagues,

Brigitte and I fully support the proposal by the MOIMS/NAV WG to approve the new project for the 5 year revision of the XML Specifications for Navigation Data Messages (CCSDS 505.0-B-1) and kindly ask the CCSDS Secretariat to establish the required CMC poll. However, before doing this we would like to submit a request to the CESG (see below) for approval.

For the 2 prototypes (originally done by NASA and ESA), we would like to propose that in this case no prototype is required based on the following argumentations:

  *   The revised book will be the result of removing material from the current version. In fact, the XML representations of the ADM, ODM and TDM, currently in the published blue book, will be migrated to the message specific books in the context of their on-going 5-year reviews (e.g. the ADM XML will be included in the ADM book revision).
  *   What will be left in the to be approved revised book is the a "Combined Instantiation" of navigation data messages (see Section 4.14) along with basic sections on XML in general. The Combined Instantiation allows merging ODM and/or ADM and/or TDM in a single file.This material will be technically unchanged with respect to the currently published book and already went through prototyping (see attached NDM/XML PROTOTYPING TEST PLAN & REPORT, yellow book)
  *   The above approached is proposed in agreement with the NAV WG chair and deputy chair.
  *   There are in general scarce resources in CCSDS, therefore avoiding unnecessary work should be welcomed by everyone.

NASA has agreed to take over the book editorship task.

We would appreciate to receive your endorsement for this approach by 28Jun16.

Best regards,

Brigitte & Mario

Berry David has requested approval of this document project: Navigation Data Messages XML Specification Five Year Revisions<http://cwe.ccsds.org/fm/Lists/Projects/DispFormDraft.aspx?id=600&Source=http://cwe.ccsds.org/fm/Lists/Projects/AllOpenChartersWithDraftProjects.aspx> within the 2.02 Navigation Working Group.

Area Director: If you did not submit this request, then your approval (then the CESG Chairman) is required before the CMC poll is set up.  Please respond to "all recipients" of this e-mail on whether you agree or disagree with that this proposal is ready for a CMC vote.

CESG Chairman: Once the Area Director has approved the submission, then it is required that you please respond to "all recipients" of this e-mail on whether you agree or disagree with that this proposal is ready for a CMC vote.

Submitter:  If your AD and CESG Chairman agrees, then the CMC poll will be set up by CCSDS IT Tech Support.  If your AD disagrees, they will work it with you.  If your AD does not respond, you should contact him to insure that he does respond.

Contact the Secretariat (Secretariat at mailman.ccsds.org<mailto:Secretariat at mailman.ccsds.org>) if there is a problem getting to concurrence on this project.

Thank You,
