[Css-csts] Draft Red FF book on CWE

Mon Jun 18 23:59:54 UTC 2018

Dear Holger,
Thank you very much for sending the notification and the link to the FF CSTS book. I will endeavor to take a look and get through the review as soon as possible. However, in the meantime, I do have a question as to approaching agency review for this. To me it makes sense, if we can, to run the reviews of the updated SFW (pink sheets) in parallel with those of the FF CSTS book.  The rationale being that if a reviewer is being thorough (yes it might happen :-)) it would be good to have both books available. Can you please let me know your thoughts on this?

Best regards,
-Erik

Dear Erik,
Please find below the link to the CSTS FF Red-1 book for your review and approval for submission to secretariat. Below is also a link to the updated CSTS SFW (now a Draft Pink Book). There are some CSTS SFW changes pending, but as said below we believe the CSTS SFW is fine for serving the purpose of reviewing the CSTS FF.

Please let us know your comments and then how to proceed.

Best regards,
Holger

________________________________

Dear Holger, Tim, and Wolfgang,
I have finished my updates of the FF book, which include the updates from Wolfgang’s review plus those resulting from the discussion that Wolfgang and I had last Monday. I believe that unless you have additional comments, this is ready to send to Erik for his AD review and approval for submission to the Secretariat to request Red-1 review. The draft FF book can be found at URL
https://cwe.ccsds.org/css/docs/CSS-CSTS/CWE%20Private/Future%20Services%20using%20Toolkit/Forward%20Frame%20CSTS/FF-CSTS-r-0_1-180615.zip

Note that there is a difference between the information Annex “Cross References to Cross Support Transfer Service Specification Framework” (Annex L) and the corresponding annexes in the MD and TD book and Guidelines. Section 4.18 of the Guidelines states “The CSTS shall provide in an informative annex a table listing the specific (sub)sections and paragraphs of the CSTS Specification Framework (reference [1]) that are referenced by the new CSTS, and identifies the (sub)sections and paragraphs of this new CSTS that make specific reference to each of those CSTS Specification Framework (sub)sections/paragraphs.” The reason that this annex is to exist is to aid the updating of the CSTS specification if and when the SFW is updated. I had suggested this particular approach. However, I have found that constructing this annex is a time-consuming and error-prone process. For the Forward Frames book I have instead listed the pages of the FF book on which the references exist instead of the (sub)sections of the FF book in which the cross-references appear. This allowed me to use Word’s built-in indexing capability. This produces a much more complete and consistent cross reference annex, and it serves the same purpose as the originally-defined annex. I recommend that we use this approach from now on. If you do not agree that this approach can be used, I can generate the (sub)section-based annex in the coming weeks, but for the purposes of Erik’s review the current form is fine. (Note also that if we take this approach, we don’t necessarily need to change the corresponding annexes MD and TD books because they still meet the intent of the annexes.)

Wolfgang had sent to me his markup of the CSTS SFW, to which I aligned the FF book. In our discussion last Monday, Wolfgang and discovered a few more changes that need to be made to the SFW, which he will make when he returns in July. In the process of finishing the FF book edits, I also discovered a very few more items that need to be updated in the SFW, mostly along the lines of making agreed changes consistent across the DP, BDP, and SCPD procedures. I have documented these needed changes in detail and will send them tomorrow to Wolfgang and copy you. I have also changed the labelling of the draft SFW to that of a Draft Pink Book and uploaded it to the CWE at URL
https://cwe.ccsds.org/css/docs/CSS-CSTS/CWE%20Private/CSTS%20Framework%20and%20Concept/CSTS%20SFW%20Pink%20Book/921x1p1x1%20draft%20180613.doc

Wolfgang and I agreed that for the purposes of Erik’s review the changes that are still to be made to the SFW are in the noise, and so we agree that we can safely point Erik to this draft for whatever cross-referencing he might choose to do.

Best regards,
John
