  *   There seems to be progress currently with the processing of books by the CCSDS Editors
  *   However, due to the large backlog, it may take at least a couple months more for MP&S BB processing

GDrive Reorganisation


  *   Action done, see https://drive.google.com/drive/u/0/folders/0B3jWkUN_retcYUxBd3p5LTJ3ZmM?resourcekey=0-XhQ3CABFWOGHmxm5Q3wf-Q
  *   By default, people with the link have read access

  *   UML Diagrams
     *   For now, the Enterprise Architect model can be maintained by Peter
     *   All diagrams were updated and included in the draft MB
  *   Sections 1-3 have been updated
     *   First drafting done, but the text requires another iteration
     *   Figures (UML diagrams) updated and included. Are the new figures clear?
     *   Tables listing all state changes have been added
        *   Suggestion to clearly mention (in the caption) that current diagrams contain a subset only
        *   Possibly add missing state changes to diagrams (if not too many)
        *   How to display the relation between state models (example: plan - actions)? New sub-section? In section 4?
     *   An example table for service support structures mapping has been provided. Is this useful? Change format?
  *   Section 4 (Use Cases)
     *   No progress, document can be found here: https://drive.google.com/drive/u/0/folders/1vf9Hf4y3laI0A7_e0FtGFB9KOiwUF09F
     *   Action on Guillermo to add text, WG to review before next meeting
     *   Discussion planned for next WG meeting, after that Peter to update the MB accordingly

Updates to the Blue Book


  *   Mainly editorials, but some have minor impact on the Information Model (regeneration of artefacts)
  *   Peter maintains an internal list of issues for the moment (inform him in case you spot anything)
  *   To be discussed and agreed at WG level before actual publication of the BB
  *   Changes to be included in the BB final issue after/during processing by the CCSDS Editors (Peter to coordinate)

AOB

From Peter.van.der.Plas at esa.int  Mon Feb 23 05:03:56 2026

Subject: [Moims-mp] Agenda and preparation for the MP&S WG meeting tomorrow
Message-ID: <DU0PR05MB104015B9D0D13B0DEF57D7B828C77A@DU0PR05MB10401.eurprd05.prod.outlook.com>

Dear all,

The agenda for tomorrow's WG meeting will be as follows:


  1.  WG status
  2.  Spring Meetings planning
  3.  Magenta Book section 3 (Information Model) discussion
  4.  Hands-on Magenta Book section 4 (Use Cases)
  5.  AOB

By now you should have received an email from the CCSDS Secretariat on the Spring Meetings location and dates. It is now also announced on the CCSDS website.

Regarding the MB section 3 (Information Model): The first draft was provided here<https://drive.google.com/drive/u/0/folders/1vf9Hf4y3laI0A7_e0FtGFB9KOiwUF09F>. Note that some of the text still needs to be added or improved. I already plan to do another iteration on the text.

At this stage, I would like the WG to reach consensus on the proposed content and structure. As such, please have a look at the draft MB and consider the following issues:


  *   Are the new UML diagrams clear? Any suggestions for further improvement?
  *   Are the tables with state changes clear? Any suggestions?
  *   The table 3-2 on Service Operations for Activities is provided as an example. Do we want such a table for each of the Service Objects? Is all the information in the table useful (like type signatures)? Any information missing? Other suggestions?
  *   Any other information to be added in section 3?

Regarding the MB section 4 (Use Cases): there is a working document here<https://docs.google.com/document/d/1aBR2y-9sUx1xj7lrzCVKBdQDe-CzujOJNt7gxKNj52o/edit?usp=sharing>. It contains an initial list of use cases to be considered. Then, I have added two ways of describing the use cases, either in tabular format or as descriptive text (see the example at the end of the document). It is the intention to brainstorm further on this, i.e. to derive the best way to represent the use cases. In addition, we should agree on the actual list (only main ones, detailed sub-cases, non-nominal cases, ...).

I hope you can make it all tomorrow,

Peter

  *   The current draft of the MB can be found here: https://drive.google.com/drive/u/0/folders/1vf9Hf4y3laI0A7_e0FtGFB9KOiwUF09F
  *   UML Diagrams
     *   In general, the diagrams are well received and considered better readable
     *   The descriptive text should be Informative, as such could be started with a "Discussion" section heading
  *   State Transition Tables
     *   In general, the tables are considered clear
     *   The labels for the transitions by Planning Function and Plan Execution Function could be improved (not using past tense)
  *   Optional Table on Service Support Data Types (table 3-2)
     *   The signature information seems to be confusing, and the column should be removed

  *   Working document can be found here: https://drive.google.com/drive/u/0/folders/1vf9Hf4y3laI0A7_e0FtGFB9KOiwUF09F
  *   The tabular example was considered too much resembling the test cases (from the Yellow Book) and as such discarded by the WG
  *   The descriptive example provided by Peter was appreciated by the WG
  *   Guillermo has started providing additional use cases with the same approach
  *   It was proposed to group the major use cases, and then have more specific use cases per group (possibly including failure cases)
  *   Guillermo to work on the use cases before the next WG meeting
  *   Peter to support Guillermo on this, and to include the draft use cases in the MB with the proper formatting

AOB


  *   Google Drive: the link provides standard read-only access, write access is provided to a limited list (send an email to Peter if you need write access)
  *   Next WG meeting: Tuesday March 24th 16:00 - 18:00, Peter to send the WebEx invite
