<p class="MsoNormal">Dear SEA SAWG Colleagues,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The CCSDS Working Meetings are upon us, starting next week. I’d like to refine our thinking for the SEA SAWG meetings. There are three motivators:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<ol style="margin-top:0in" start="1" type="1">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo1">The draft RASDS++ is in Tom Gannett’s capable hands. Apparently it’s been a bit tough for him to hammer it into proper shape, but we know well what it contains, he will affect the
from, but not the contents.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo1">We have made a lot of edits to the SCCS-ARD and worked to clarify the definitions of the SSI Stages and the evolutionary path among them.
<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo1">We have a few documents that have been awaiting attention until the work on these two have wrapped up. We need to decide whether we are going to re-confirm them, revise them, or retire
them. Those are the options. The documents are:<o:p></o:p></li><ol style="margin-top:0in" start="1" type="a">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level2 lfo1">SCCS-ADD, CCSDS 901.0-G-1, Space Communication Cross Support Architecture Description Document. The descriptive Green Book companion to the SCCS-ARD.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level2 lfo1">RASIM, CCSDS 312.0-G-1, Reference Architecture for Space Information Management. A Green Book describing info management functions and uses, including registry and repository functions.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level2 lfo1">Security Architecture, CCSDS 351.0-M-1, Security Architecture for Space Data Systems. This is really a SEA Sec WG document, but it is to elaborate on RASDS++ themes so it is worth
discussing here too.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level2 lfo1">SSI Architecture, CCSDS 730.0-G-1, Solar System Internetwork (SSI) Architecture. This is a SIS DTN document, but it probably should be brought in line with the SCCS-ARD updates and
any of the latest thinking from the IOAG Committee to Study LunaNet Governance (CSLG).<o:p></o:p></li></ol>
</ol>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We do not have the resources to tackle all of these at once, and we may wish to just retire or reconfirm some of them. And some do not belong to the SAWG, but we have an interest in them and wish to coordinate with these other WGs.<o:p></o:p></p>

assign ISO number that both SC13 & SC14 can reference.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo2">Any other business.<o:p></o:p></li></ul>
