SEA CESG SUMMARY

1. SEA CESG SUMMARY Rome, Italy, 16 June 2006

2. SEA: Meeting Scheduleand Locations

3. SEA Includes: System Architecture, Information Architecture & Security Working Groups SANA WG (starting to meet as WG now) XML Standards and Guidelines SIG (cross WG effort) Delta-DOR SIG (cross WG effort) SGIA BoF (no IOAG / agency support) Responsibilities Overall architecture for space mission communications, operations, and cross-support Coordinate and collaborate with the other areas about architectural choices and options Support the CESG in evaluating consistency of all area programs of work with the defined architecture Create such working groups and BoFs as are required to progress the work of CCSDS System Engineering AreaOverview

4. System Architecture WG - meeting this week Develop a high level system architecture reference model (and formal methodology and tools - deferred as work item) Finalize Reference Architecture for Space Data Systems (RASDS) V1 Magenta Book, resolved handling of RIDs Discuss future BoF to work on object attributes & templates Information Architecture WG - meeting this week Develop a high level Information Architecture reference model and definitions of active and passive information objects Finalize Reference Architecture for Space Information Management (RASIM) V1 Green Book Discuss process of work to define component interfaces and standards w/ MOIMS IPR, focus on only schema registries concern Security WG - meeting this week Develop security overview & threat assessment, and security architecture, framework and related standards Progress Security Architecture and other specific security elements (Key management, Crypto and Authentication Standards) Discussions with other WGs were useful, but conflicting needs / requirements identified System Engineering Area:Current WGs and BOFs

5. SANA WG - meeting this week Develop detailed requirements for the Space Assigned Numbers Authority (SANA) Review proposed approach & requirements Only NASA support, task will proceed as support activity to CCSDS and Secretariat Other agencies are welcome to review and / or participate New BoFs Space Ground Interoperability Architecture BoF - meeting this week Develop an end to end space / ground cross support architecture and services catalog in response to IOAG request Work may be de-scoped to only services catalog No IOAG / agency support, draft resolution for IOAG response Still not clear that this is going to go ahead as CCSDS effort, cannot without resources Relationship to proposed object / template BoF unclear System Engineering Area:Current WGs and BOFs

6. Delta-DOR SIG - meeting this week, no feedback Develop detailed requirements for delta differential one-way ranging (Delta-DOR) service Coordinate work in other WGs (SIS/Ranging, CSS/CSTS, MOIMS/Nav) Develop integrated vision of service and interoperability points Develop any over-arching documents, as needed XML Standards and Guidelines SIG - meeting this week Develop a set of common standards and guidelines for XML use across CCSDS Coordinate work in other WGs (MOIMS/Nav, MOIMS/SM&C, CSS/SMWG, SEA/IAWG) Product will be a set of guidelines for all CCSDS WG that use XML to follow Namespace RFC in development, soon to go out System Engineering Area:Current Special Interest Groups (SIGs)

7. A CESG poll for “Approval of RASDS for Agency Red-1 review” was posted in March 2006, and comments were received from the CESG Chairman and the SIS Area Director. Another comment was received from an industrial partner. The WG reviewed these comments. The WG agreed to the disposition on the received comments and the final document will be developed shortly. A proposal was made to create a BoF to develop the charter of a WG to develop templates of service catalogues. SAWG Executive Summary

8. The draft Information Architecture Green Book RASIM was discussed. Input was received from both NASA and CNES from the March version. A May version was distributed which included several updates. Minor updates need to be made as a result of this meeting. A new version will be distributed for final comments by the beginning of July. The meeting also discussed the importance of developing some best practice case examples using RASIM modeling and functional components. A discussion occurred about the use of RASIM to support SANA A joint meeting occurred with IPR related to registries (albeit narrowly focused on schema registries) IAWG Executive Summary

9. Attendees from CNES, BNSC, ESA/ESOC, ESA/ESTEC, ESA/ESRIN, DLR, NASA/MSFC, ASI, CSA (Viagenie) and NASA/JPL. Major participation by ESA! Majority of attendees from multiple establishments. Discussed and revised the SecWG Security Architecture documents and decided that it should not be Blue but rather (probably) Magenta. Fold key management into architecture document. Discussions regarding whether this architecture should be informational or proscriptive Final thoughts that it should be informational Discussed the encryption and authentication draft documents. Some controversy on this – ESA did not see the need for standardizing on algorithms They didn’t need it for interoperability They want more than just algorithms Agreement to add more “meat” to the drafts to further explain the need and desirability to have such recommendations. Revised the charter and workplan. Working group to think more about the workplan and provide comments to finalize the revision. Discussed the draft of the secure interconnection guide. Major concern was that it was too generic whereas the original NIST 800-47 was too US Govt centric. Agreed to make the document more space-centric. Discussed and agreed to a resolution of the public exposure of SCIDs. Held a successful joint meeting with SM&C, Navigation, AMS, and SANA Agreed to develop a strawman security architecture/design in response to SM&C requirements. SecWG Executive Summary

10. Executive Summary Reviewed ops concepts SCID, Heat Sensor and VoIP Changed to SCID, XML Schema and Heat Sensor Took action to create a White Paper on SCID future expansion to accommodate more spacecraft Reviewed the SANA Action Plan and assigned actions (no major comments) Cat 1 SCIDs and CA: MSFC Cat 2 Current CCSDS Standards and Processes: JPL Cat 3 Current WGs/SIGs/BoFs: Secretariat Cat 4 All others: TBD Resource: No international participation, proceeding to define service Schedule requires changing with the creation of a white paper Even though a review of the charter was scheduled it was not required due to the limited participation (everyone was familiar with it) Progress Achieved Clarified SANA scope addressing SCIDs and eventually unique numbering on a larger scale (phased) SANA addresses numbers and names and addresses Added a Glossary Place emphasis on CCSDS related registry requirements first SANA proposed implementation of a Registry of Registries was discussed Discussion of Green/Magenta book was discussed deciding on a Green Book Detailed discussion on ops concepts and suggestion to establish thread from the RoR to a detailed xml schema Schedule SANA Executive Summary

11. XSG is currently drafting an XML schema Naming and Design Guidelines(NDG) document. Requires CESG consensus and approval Needs RFC formatting for submission Schedule is to submit a final draft of namespace and versioning sections of NDG to CESG by 09/30/2006 An annotated outline of full document will be supplied by 09/30/2006 with recommendations for priorities based on CCSDS WG requirements The XSG SIG will deliver further NDR draft sections by 01/2007 based on CESG input on priorities XSG SIG Current Status

12. Significant resource will be needed both to complete the XML Schema NDR and to supply the domain knowledge to enable the development of reusable and Interoperable XML Schemas The XSG recommends the XML SIG be dissolved and a BOF be created so appropriate levels of resource can be assigned to this effort. The XSG SIG will lead this BOF and supply a draft charter as input to the BOF if requested by the CESG. XSG SIG Issues

13. Highly distributed or once a year meetings Will make SEA tasks nearly impossible / highly costly Particular effect on Security WG and also cross area SIGs CCSDS Architectural Principles, as called for in A02.1-Y-2 & A00.0-Y-9 XML Standards & Guidelines development process SANA direction & support from other agencies SGIA futures Lack of participation from IOAG, other agencies / WGs Relationship to other space data system efforts Global Earth Obs Sys of Sys (GEOSS), Geneva WMO, all space agencies w/ Earth Obs Coord obs & sci, 10 yr plan NASA / Constellation & SCAWG activities Interoperability and cross support Manned & robotic exploration at the Moon and Mars Other Issues & Concerns
