Produce documents that will provide an architectureal description of the CCSDS work, understanding of the links/interactions between the different standards, identification of gaps, and provide the means to describe these architectures, information models, and policies in a consistent way. Produce a CCSDS Application Layer Architecture showing the relationships among all of the application layer standards and services and their relationships to supporting standards for space communication and cross support. This is a companion document to the Space Communication Cross Support architecture (SCCS-ADD) that documents SLS, SIS, CSS, and SEA standards relationships. Work with MOIMS and SOIS to document the relationships between the standards in these two areas and with those already documented in the SCCS-ADD. Revise the CCSDS Reference Architecture for Space Data Systems (RASDS) to accomplish its 5-year review and, in a second phase, augment the existing document with methods using Model-Based System Engineering (MBSE) and SysML. Working with the other areas, update the CCSDS Glossary to provide a self consistent and unambiguous set of terms. Create a Registry Management Policy and related procedures and information models for managing the sets of registry information created by the other CCSDS areas.
