I will point out that we do have a similar issue with RASDS itself which is explicitly focused on its ability to support the documentation and understanding of space data systems architectures, but the methods do have broader applicability than that and have been adopted in other venues. In a related fashion, somewhat like your references to PMBOK and DMBOK in </span><span style='font-size:11.0pt'>653.0-M-1</span><span lang=EN-US style='font-size:11.0pt'>, we reference ISO 42010. We do explicitly adopt 42010 as a meta-meta-model, so this is addressed explicitly where it must be for background and understanding of the concepts of metamodel levels, an important aspect of this whole framework from the outset.

As I initially commented but maybe not clearly enough, you seem to have sprinkled these concepts in several places in the document. You take the time to explain, also in several places in the body of the document, that they are similar but different and that in some cases you have adopted one, or the other, or some totally new term. My recommendation is that you move all of that discussion into the existing Annex B, and that you resolve all of the terminology issues there, in the Annex. Then you can point at that Annex at the front of this document, and name the sources, but only use the agreed set of terms in the body of the document without having to explain in each section why you chose one and not the other. It will make for a much cleaner and clearer presentation of the concepts that you really want to promote.<o:p></o:p></span></p><p class=MsoNormal style='margin-left:36.0pt'><span lang=EN-US style='font-size:11.0pt'> <o:p></o:p></span></p><p class=MsoNormal style='margin-left:36.0pt'><span lang=EN-US style='font-size:11.0pt'>In the matter of the rather confusing collection of diagram styles used in </span><span style='font-size:11.0pt'>CCSDS 650.0-M-3, I </span><span lang=EN-US style='font-size:11.0pt'>do understand that you would prefer to not change these diagrams, and that you wish to continue to defer fixing them to some indefinite point in the future.

There are a couple of terms (CRIS and GDPR) that are named, but never clearly defined nor tied to any specific source. I am fairly certain that CRIS does not mean Construction Risk and Insurance Specialist nor Certified Release of Information Specialist. The introduction of PMBOK and DMBOK is very useful, but it would be better just handled in Annex B and not scattered repetitively in the document. Strongly recommend defining your terms clearly and moving on. The choice of the term "Collection Groups" instead of something like "Process Groups" seems a little peculiar and bothersome. They are, after all, ""processes and not ""collections. It may be a pain, but I would recommend re-thinking this choice of terms now.</span><span lang=EN-US style='font-size:11.0pt'><o:p></o:p></span></p><table class=MsoNormalTable border=0 cellspacing=0 cellpadding=0 style='margin-left:36.0pt;border-collapse:collapse'><tr><td width=601 valign=top style='width:450.8pt;border:solid windowtext 1.0pt;padding:0cm 5.4pt 0cm 5.4pt'><p class=MsoNormal><span style='font-size:11.0pt'>MOIMS-DAI PROPOSAL <a href="https://urldefense.us/v3/__http:/review.oais.info/show_bug.cgi?id=394__;!!PvBDto6Hs4WbVuu7!OYv0NDiPNOY-iJo-iFVGKXpvN7sRiV74GTVUca26WxN0Bjm1NfgX95gl4WwZ0IxylvJjHqk2txNtDwDqYTDkPmCY$"><span style='color:#467886'>http://review.oais.info/show_bug.cgi?id=394</span></a><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt'> <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt'>1) We note that CRIS and GDPR are in Acronym list.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt'>However, we propose adding the expansion of the acronyms at 1st occurrence see section 4.2.3.4 and 4.2.3. <b><span style='color:#00B050'>Ok</span></b><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt'> <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt'>2) We disagree. PMBOK/DMBOK is mentioned briefly in the introduction and then in detail in sections 2.1 and 2.2, as examples of related best practice to justify our approach, which we do not think can be described as “scattered repetitively in the document”. <b><span style='color:red'>Issue still exists. These two docs, and their terms, appear in several places, repetitively. And then there is a whole section, Annex B, that talks about both of them and their different uses of terms. This document would be better served by using Annex B to sort out the terms and define the set you are going to use, once. Then you can introduce these sources, once, in the beginning, use the terms you define in Annex B throughout, consistently, without continually having to describe these two sources and how they differ. These then become your IPELTU terms instead of always referring to them as “PMBOK does this and DMBOK does that”.

The current set of diagrams is unclear and it is easy to confuse different kinds of rounded, clipped, burnished, objects. Furthermore, the diagramming styles adopted are not even consistently used throughout the document. Compare "information objects" shown in Figs 2-3 & 2-4 with those shown in sec 4.

While there has clearly been some amount of attention paid to the diagrams used in this document they remain, to my eyes, inadequate, unclear, and inconsistent. The use of nearly identical rounded, elongated, clippped corner objects to distinguish systems, functions, and organizations is unclear. We now have a significant body of CCSDS documents that have successfully used RASDS to create diagrams that represent all of these same kinds of concepts (and more). I can see no good reason, aside from the modest amount of time needed, for this document not to be brought in line with those conventions. The results would be both alignment with the rest of these CCSDS documents, at least one of which references this same subject, and more importantly, increased clarity. In addition, the document itself is internally inconsistent, since it uses at least three different drawing styles to represent "information". Compare the "information objects" in figures 2-2, 2-3 (what are those brown things?), and the information objects modeled using UML in sec 4.3.1. If more effort were put into consistent use of a standard representation, and less into creating "pillowy" shaded objects, the document would be much improved.</span><span lang=EN-US style='font-size:11.0pt'><o:p></o:p></span></p><p class=MsoNormal style='margin-left:36.0pt'><span style='font-size:11.0pt'> </span><span lang=EN-US style='font-size:11.0pt'><o:p></o:p></span></p><table class=MsoNormalTable border=0 cellspacing=0 cellpadding=0 style='margin-left:36.0pt;border-collapse:collapse'><tr><td width=601 valign=top style='width:450.8pt;border:solid windowtext 1.0pt;padding:0cm 5.4pt 0cm 5.4pt'><p class=MsoNormal><span style='font-size:11.0pt'>MOIMS-DAI PROPOSAL <a href="https://urldefense.us/v3/__http:/review.oais.info/show_bug.cgi?id=396__;!!PvBDto6Hs4WbVuu7!OYv0NDiPNOY-iJo-iFVGKXpvN7sRiV74GTVUca26WxN0Bjm1NfgX95gl4WwZ0IxylvJjHqk2txNtDwDqYTWt1dGR$"><span style='color:#467886'>http://review.oais.info/show_bug.cgi?id=396</span></a><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt'> <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt'>Vote 2) <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt'>We do not this the request is reasonable.
