<p class="MsoNormal"><span style="font-size:11.0pt"> <o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Please find attached the SEA resolution concerning the request for CMC authorization to formally initiate the document projects to create the CCSDS Application and Support Magenta and Green Books. These documents
are the response to the CMC request that the SEA produce a "CCSDS Reference Architecture". The initial analysis and descriptive work has actually begun in the SAWG and the initial draft of the approach, in PPT format, as agreed by the CMC, is nearing completion.
This request is to approve the formal document projects and to provide the necessary resources to create the actual Magenta and Green Book documents.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">These CCSDS Application & Support Layer Architecture are being produced in a phased approach: The initial cartoon version describes MOIMS / SOIS applications domain, the services, functions, interfaces, and
information objects and their use of CSS, SLS, SIS, and SEA services and functions, based on SCCS-ARD. The primary focus in this document is upon the applications domain (MOIMS and SOIS), and their services and interactions. The underlying communications
layers and related services, from SLS, SIS, CSS, and SEA are already well covered in the SCCS-ARD and ADD. Following concurrence on the contents of the initial draft, in PPT form, a more complete MB & GB document version will be produced.<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">The document will describe how all of the CCSDS application and support layer (file and message) standards fit together, and how they rely upon underlying communication services, providing, in combination,
a complete map of the CCSDS architecture. During development of the MB the WG will review any necessary services, interfaces, functions, information objects, and ontology terms with the affected working groups. The document will be developed with the direct
support and involvement of SOIS and MOIMS area experts.<o:p></o:p></span></p>
