1. SOIS-APP Working Group Report Jonathan Wilmot (WG Chair)
Richard Melvin (WG Deputy Chair) 1 1 1

2. SOIS-APP Executive Summary
Goals for this meeting cycle:
Discuss and document updated SOIS architecture and SEDS use cases
Determine the interoperable interfaces at each architectural layer
Align updated SOIS architecture with SEA, MOIMS concepts
Discuss relationships and/or architectural overlaps with SEA and MOIMS WGs
Discuss and disposition SEDS and DoT book RIDs
Discuss results of ESA study to autogenerate data acquisition flight software solely on SEDS definition of devices
Discuss results of NASA effort to integrate SEDS in the cFS software framework
Discuss results of NASA effort to generate operations XTCE database from SEDS
Discuss results of CAST implementation of SOIS architecture
Working Group Status:
Accomplished all stated goals of meeting (listed above)
Determined there are overlapping areas with MOIMS MO services
All RIDs and Github issues discussed and dispositioned
JAXA is interested, resources being identified. Possible issues getting resources allocated / schedule.

3. SOIS-APP Executive Summary
Working Group Status (continued):
Decision to Silver existing app books: M-1, M-1 , M-1, M-1, M-1, M-1, M-1 and move conceptual primitives to SOIS G-2
Reviewed draft of CAST Flight Software as a CCSDS Onboard Reference Architecture
Problems and Issues:
Very limited funding for contractor support in FY17 (Ramon Krosley is book author)
NASA projects waiting book updates
Planning:
Richard will review the MAL for SEDS overlap/translatability (funding TBR)
Update and reissue G-2 (will include some of the user’s guide content)
Update XML Specification for Electronic Data Sheets BB
ESA primes to study EDS (starts second half 2017)
NASA and CAST SEDS prototyping in work
Complete and submit Electronic Data Sheets and Common Dictionary of Terms - Overview (870.1-G) and include user’s guide content
Delete Spacecraft Onboard Interfaces Services User’s Guide project
Interaction with other WGs:
Joint meeting with SEA and MOIMS working groups
SOIS representative participation in SEA WG
JAXA is interested, resources being identified. Possible issues getting resources allocated / schedule.
