<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Just a friendly reminder that we have a working meeting scheduled for tomorrow, Friday the 13’th, 13 May 2022, from 0700 PDT to 1000 PDT. We have several action items as shown below.

<p class="MsoNormal">Dear RASDS group,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As scheduled we had a meeting of the SAWG today, 9 May, to discuss the RASDS edits. Attendees were: Ramon Krosley, Christian Stangl, Fred Slane, Peter Shames.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Discussion points:<o:p></o:p></p>
<ul type="disc">
<li class="MsoListParagraph" style="mso-list:l7 level1 lfo3">Ramon Krosley presented the work he has done to use the Ontology Markup Language (OML) to model the ISO 42010 baseline systems architecture ontology and also the new Physical Viewpoint and the Connectivity
Viewpoint.<o:p></o:p></li><li class="MsoListParagraph" style="mso-list:l7 level1 lfo3">The OML language and tools are described at
<a href="https://urldefense.us/v3/__https:/www.opencaesar.io__;!!PvBDto6Hs4WbVuu7!diOB9wlne_EGleAEcsVuLNs4GeRzIJvd5jmUhR3Ag0Es2WltUftxjXNKaFy8PSL0JpKoyljW$">
https://www.opencaesar.io</a>. There is a downloadable spec and also a set of tools that will plug into the Eclipse framework.<o:p></o:p></li><li class="MsoListParagraph" style="mso-list:l7 level1 lfo3">Ramon developed a representation of ISO 42010 using OML that addresses all of the base concepts of viewpoint, view, correspondence, etc, as reflected on pg 4 of the current VG set. Once you learn
the most basic syntax OML is pretty easy to read and understand, but it is also capable of complex expressions of relationships.<o:p></o:p></li><li class="MsoListParagraph" style="mso-list:l7 level1 lfo3">Ramon also showed an initial representation of the new Physical Viewpoint that we need for the ISO TC20/SC14 work. One of the observations that came out this is that the Physical Viewpoint, which
defines the base attributes of physical objects and their “connections”, should really be the basis of the Physical Viewpoint and also the derivation point for Connectivity and other physical viewpoints like structural or energetic.<o:p></o:p></li><li class="MsoListParagraph" style="mso-list:l7 level1 lfo3">Ramon plans to elaborate these OML descriptions further and to explore the Eclipse tooling<o:p></o:p></li><li class="MsoListParagraph" style="mso-list:l7 level1 lfo3">Fred & Peter discussed a possible change to the RASDS document outline to better accommodate the primacy of the Physical Viewpoint. We had been saying some of this for the last few meetings, but
it came into greater focus during today’s meeting.<o:p></o:p></li><li class="MsoListParagraph" style="mso-list:l7 level1 lfo3">The existing Connectivity VP, which is so important to CCSDS, is understood to really be a sub viewpoint, or aspect, of the Physical Viewpoint. The Physical Viewpoint also is used for Structural
(materials, junctions, interfaces) and Energetic (electrical, thermal, mechanical, magnetic, thrust, …) properties. The proposal for RASDS++ is to introduce the Physical Viewpoint first, then to derive the Connectivity viewpoint from that so that it still
has prominence (for older RASDS users), and following that one or more “SC14” views like structural or electrical to show how these are related.<o:p></o:p></li></ul>
<p class="MsoNormal">Action items:<o:p></o:p></p>
<ul type="disc">
<li class="MsoListParagraph" style="mso-list:l7 level1 lfo3">Peter to craft a revise Table of Contents showing what is proposed to be changed / added<o:p></o:p></li><li class="MsoListParagraph" style="mso-list:l7 level1 lfo3">Ramon to revise / extend the OML representations and to explore the Eclipse plug-in for visibility<o:p></o:p></li><li class="MsoListParagraph" style="mso-list:l7 level1 lfo3">Fred to define which additional 1 or 2 Physical “aspect” viewpoints that SC14 would accept in RASDS++, such as “structural” and “energetic”<o:p></o:p></li></ul>
