8. PS 8 19 September 2005 SAWG Executive Summary 1. Review of the RASDS document was done by the SAWG members and an expert on RM-ODP. Some issues were found but the WG agreed to necessary updates to the document. 2. It was agreed to send the updated RASDS document, based on the discussion at this meeting, to CESG and CMC for approval as a Recommended Practice document. 3. It was also agreed that the work on development of a RASDS formal model should be continued in some form (preferably by a CCSDS BoF/WG) leveraging the liaison relationship established with the ISO/IEC group developing “UML for ODP.”

9. PS 9 19 September 2005 SAWG Summary Technical Status 1.Systems Architecture WG Goal: Develop a reference architecture and a formal representation method Working Group Status: Active ___ Idle ___ Will be terminated _X_ Working Group Summary Situation: Working Group Summary progress: Updated the RASDS document (near BCP), Started to develop a formal model (before WB) Problems and Issues: Ordered by CMC to terminate Development of formal model is deemed essential by SAWG Status:OKCAUTIONPROBLEM Comment:Must be terminated

10. PS 10 19 September 2005 SAWG Summary of Goals and Deliverables 1.Define a reference architecture that provides a framework for generation of space data systems standards and development of space data systems. 2.Document the reference architecture identifying basic elements. 3.Develop a document that provides to the other Working Groups and BoFs guidelines on how to apply the reference architecture. 4.Develop formal methods for representing space data systems architectures that will enable sharing of architectural information among engineers. 5.Develop tools that will facilitate design, modeling, and simulation of system architectural designs. SAWG Work Stopped

11. PS 11 19 September 2005 SAWG Progress Achieved 1. With regard to items 1 and 2 (see the previous page), a review of the RASDS document was by the SAWG members and an expert on RM-ODP. The WG agreed to necessary updates to the document and the final draft of the document will delivered shortly. 1. Change the”attribute” section to “characteristics” section 2. Define Software & Hardware Engineering Objects 3. Clarify Viewpoint Specifications vs. Views 4. Change order of the sections for better flow 2. With regard to item 4, it was agreed that it should be developed by another BoF/WG of CCSDS with a close liaison relationship with the ISO/IEC WG that is developing “UML for ODP.”

12. PS 12 19 September 2005 SAWG Near-Term Schedule The SAWG will be terminated after delivering the final Recommended Practice document to CESG. Some members of SAWG will participate in the activities of SGIA and there is an intention to use the RASDS to develop SGIA. A draft charter for a BoF that develops a formal model of space data systems will be generated. In the meantime, some of us (at least NASA, CNES and JAXA), as representatives from the space community, plan to review “UML for ODP” and generate comments.

13. PS 13 19 September 2005 SAWG Risk Management Update We believe that one of the reasons why RASDS is not accepted well within CCSDS may be that we haven’t successfully shown how it can be used in space data systems. SGIA is seen as a means to validate the RASDS concepts by applying them to a real problem that the IOAG and CMC have posed. JAXA has a plan to use RASDS to develop a database that stores information on spacecraft with a standard format. The concept of the database in the first phase is shown in the next slides. JPL has a research task that is also extending RASDS to describe space systems.

14. PS 14 19 September 2005 SecWG Executive Summary Attendees from CNES, BNSC (telecon), NASA/GSFC, NASA/ Langley (telecon), ESA/ESOC (a first!), DLR, NASA/JPL & NASA/GRC (brief) Discussed and revised the SecWG Security Architecture documents Discussed and accepted proposals for CCSDS standards for: Encryption (AES w/ min 128-bit key, additional algorithms allowed) Authentication/integrity (Digital Signature Standard for public key- based authentication, HMAC-SHA1 for MAC-based authentication) Discussed CNES approach to developing security requirements and their use of the EBIOS tool Discussed the development of: Security Policy Framework Information Security Planning Guide - Potential usage of Common Criteria to develop mission Protection Profiles Discussed issues from NASA DSWG – identity management, SCID “exposure” on SANA (aggregates of public data may be a security risk).

20. PS 20 19 September 2005 IAWG Executive Summary Six people attended the IA meeting from JPL, GSFC, Marshall and CSA. The draft Reference Architecture for Space Information Management Green Book was discussed Included the updates from the NASA TIM that occurred in August. Established much improved convergence between GSFC and JPL with respect to the relationship between IA and OAIS. Chapter 2, the information model, requires more substantial updates than Chapter 3, the functional information management components. The afternoon IAWG session was canceled in lieu of the meeting on XML best practices (XSG SIG)

21. PS 21 19 September 2005 IAWG Summary Technical Status 1.Information Architecture WG Goal: Develop a reference architecture for space information management as extension to RASDS Working Group Status: Active _X_ Idle ___ Working Group Summary Situation: Working Group Summary progress: Updated the RASIM document (nearly complete GB), Discussed how to transition to development of components & interfaces Problems and Issues: Agreement on transition is still unclear Availability of agency participants with right skill set is uncertain Transition Unclear Comment: PROBLEMCAUTIONOKStatus:

22. PS 22 19 September 2005 IAWG Progress Achieved Significant progress has been achieved since July and we have received quite a few positive comments. Participants seems willing to continue their involvement and to see the Green Book get published. Some discussion occurred on the need to develop more examples to clarify use of abstract components to build different classes of information systems. Some discussion occurred on the need for a TIM on registries, at least at the NASA level, but broader participation is welcomed.

23. PS 23 19 September 2005 IAWG Near Term Schedule

24. PS 24 19 September 2005 IAWG Open Issues Similarities exist between “Reference Architecture for Space Information Management” and the OAIS, but differences are: OAIS is an archival reference model and process that focuses on preservation and data archives. Data model is specific to archiving. IA focuses on a cross-cutting information management reference architecture applicable across mission lifecycle and components that can be used to build a variety of informtion management systems. May need to develop a separate process model for the RASIM end to end information infrastructure Modeling notations and disagreement on how to best render an architecture still continues to be problematic Using UML class diagrams for components, interfaces and data models

25. PS 25 19 September 2005 IAWG Resource & Coordination Issues Participation by individuals with solid experience architecting data-driven systems IA-related meetings occurring in multiple places (Atlanta and Toulouse) which prevents adequate cross-group interactions. There may not be commitments from member agencies for enough resource to achieve deliverables. ESA and CNES considered important stakeholders, but participation has been very limited. Critical that a combined registries effort be initiated across existing groups. XSG SIG discussion identified need for schema registry, other have been identified Once it completes current high priority task XSG SIG may form nucleus for discussion of this topic

26. PS 26 19 September 2005 SANA BOF Executive Summary SANA BOF on 15 September 2005 in Atlanta, GA 8 representatives included NASA (JPL, GSFC, MSFC), ESA Intention Establish plan, processes and recommended practices for CCSDS Space Assigned Numbers Authority (SANA) Define content, overall approach, and means for updating included information Define how the SANA would work with different CCSDS WGs, registries, and with agency specific elements Establish practice for future maintenance and sustaining of the SANA Motivation: Primarily provide access to CCSDS global information - Manage central info centrally as authoritative source - Support local management of distributed agency & mission info, provide central pointers to their authoritative sources Existing SANA is largely conceptual, as defined in CCSDS A02.1-Y-2. Restructured Organization and Processes for the Consultative Committee for Space Data Systems. Yellow Book. Issue 2. April 2004: “SANA” materials are in some existing repositories and also are buried within a number of different CCSDS documents Users have a very difficult time locating these within the CCSDS web site and understanding how they relate one to the other

27. PS 27 19 September 2005 SANA BOF Recommendations Update the SANA charter to reflect agreements from meeting and submit to the CESG for approval Ensure that the SANA can deal with the complexity of future spaceflight programs, projects and the technologies involved Help reduce stove piping Setup a mechanism to access and apply specific information technologies through registry processes and artifacts (CCSDS common S/W) Introduce information management commonality across operational domains Enable interoperability & reuse (data dictionaries & glossary, schemas, assigned numbers, common name registry) Provide commonality at the technical & operational level among disparate projects and development organizations Single point of (common) access for management, technologists, developers and operators to technically relevant CCSDS related information (SANA=web link management)

28. PS 28 19 September 2005 SANA BoF Recommendations, contd Primary SANA Contents, in order of priority, are to be: CCSDS Registries - Common IDs (ground stations, spacecraft and space objects) - Services discovery (cross support, interoperability) - Common Metadata (Data element, dictionary, glossary, acronyms) - Schema - Pointers to agency registry entrypoints Standard Information Models Standard Namespaces Assigned numbers from standards e.g. CCSDS, IETF….. SCPS-TP: Keith Scott - Vendor IDs for specific implementations i.e. gateway SCPS-TP White Paper June 23, 2005 - Assignment of Extended Capability Binding Space Identifiers Pointers to standard software objects, XFDU plug-ins, applications services and APIs Pointers to reference implementations (XML, coding, compression, protocols, …) Potential future activities: Space name and address domains e.g. operational, network…. Messaging e.g. AMS - Continuums, nodes, zones….. - Message types

29. PS 29 19 September 2005 SANA BoF Objectives Objective 1: Establish a CCSDS system of registries for space assigned numbers for current and future international space operations and information management. Objective 2: Coordinate and integrate current registry processes and other operational information into a single unified standardized framework working with cooperating organizations. Objective 3: Provide a focal point from which any authorized organization or individual can acquire technically relevant CCSDS registry and other information. Objective 4: Setup SANA operations group and develop rules and processes to operate and support the SANA and identify the resources needed for the continuing operation, deployment, outreach, and evolution. Objective 5: Transition this to a working organization under CESG responsibility.

30. PS 30 19 September 2005 SANA BoF Issues & Risk Management Technical risks: No significant technical risk is involved. Technical risks are low since this is essentially process based. The prototype activity does not entail any cutting edge technologies. Management risks: Some management risk is involved including the usual politics and consensus building necessary for success. Issues: Issues of privacy, ownership of data Issues of security and access to aggregated information International resources for the WG and operations team

31. PS 31 19 September 2005 SGIA BoF Executive Summary 11 representatives included NASA (JPL, MSFC), ESA and JAXA participation Attendees: Shames, Okino, Crichton, Weiss, Yamada, Kearney, Peccia, Gannet, Hughes, Reich, Hartmann Coordination Identified: - JPL and MSFC are actively supporting effort - ESA has indicated that they will provide some level of support (telecon, email coordination level) – support from existing SAWG members - CNES & JAXA are seeking support General agreement on: Charter of SGIA Some CHANGE in terms of generalization as to the service provider/user model, specifically do not constrain to SLE General agreement on: 5 step process Some CHANGE in terms of language to capture iteration and stakeholder feedback towards - the cross support service catalog - cross support service architecture Some CHANGE in terms of refinement of the content, including process as well as the level of detail of the cross support service catalog was identified.

32. PS 32 19 September 2005 SGIA BoF Discussion There was general concern as to what the SGIA architecture would entail: A specific suggestion was that it may be sufficient to provide gateway interfaces Possible options are to present interoperability at the gateway level or end-to-end service along with identified confederated nodes and profiles. Desire to ensure that existing organizational boundaries and implementation approaches are accommodated Leverage IOAG DRAFT catalog and architecture Schedule - general belief we could get an initial WB by June 06 meeting There was some concern about the scope and meaning of “profiles”.

33. PS 33 19 September 2005 SGIA BoF Action Items Update Charter and process to represent agreements, submit to CESG Agencies need to identify suitable Technical Point Of Contact (TPOC) within their operational organizations to be participants in the process - TPOC must be able to provide view of current and future services - TPOC will also act as IOAG “stakeholder” and early reviewer of the proposed products of the WG - Intent is to pursue from top-down and bottom-up approach Expressed need for contact with JAXA, CNES, and DLR (at a minimum) for participation in WG No representation at meeting from DLR & CNES

34. PS 34 19 September 2005 SGIA Risk Summary Not yet getting essential support - CCSDS WG Technical Personnel - IOAG TPOCs as Active Stakeholders

35. PS 35 19 September 2005 XSG SIG Executive Summary XSG SIG on 14 September 2005 in Atlanta, GA 23 representatives included NASA (JPL, GSFC, MSFC), ESA, CNES, OMG SDTF, and other participation Intention Establish guidelines and recommended practices for CCSDS XML schema, naming, and usage before this first set of schema, from several different working groups, become finalized and externally visible Define common rules, naming and style guides, define URL hierarchy and namespace architecture, define versioning and use schema location as a resolvable URL Motivation: Get CCSDS namespace and rules sorted out before current standards are finalized Four separate XML schemas are in development, there is no consistency of naming, usage, namespace, etc across them Enable interoperable implementations of SW and systems Create collaborative solutions and an authoritative source for CCSDS and agency use

36. PS 36 19 September 2005 XSG SIG Recommendations Create a small working group of current XML schema authors and experts to develop short term approach XML Stds & Guidelines SIG Erik Barkley David Berry Lou Reich (chair) Gerry Simon CNES ? (Lapaian acting) ESA ? (Peccia acting) Define a URL hierarchy and namespace architecture Create a naming and style guide, including guidelines for development of schema and namespace Define versioning approach Create a resolvable URL for schemaLocation, ( create a CCSDS server for these, future) Define levels of XML schema reusable components (potentially based on the UBL model) Define approach for consistent use of qualified and unqualified types, elements and attributes Get a CCSDS NID by submitting an RFC to IETF, establish base for URN, list of 23 exist now (RFC 3406, May 2005), see also IANA registry of URI (RFC 3986)

37. PS 37 19 September 2005 XSG SIG Issues Issue of impact of this stds effort on immediate WG products and schedules? Approach for current standards, hold until modified or release as Red-1 now with agreement to change before Red-2 is sent out? How long will it take to develop these top level standards elements? (by Xmas is target) How long will it take to modify existing XML schema to be compliant? How to arrange agreements on common schema between CCSDS & OMG?

39. PS 39 19 September 2005 SEA Liaisons SysML Partners have developed a system engineering modeling language based upon UML 2.0. A liaison has been agreed to, which opens up a communication channel between the SEA and SysML groups. The intent is to provide the SysML solution to CCSDS for their validation for application to Space Systems. SysML agreed to form a liaison w/ CCSDS. SEA, on behalf of CCSDS, has agreed to that liaison and several joint meetings have been held. The SysML spec is currently at version 0.9. Four UML tool vendors have demonstrated SysML 0.9 compliant versions of their tools. A summary presentation is available from the SysML web site. An informal liaison has been developed with ISO/IEC JTC 1 / SC7 which is developing an UML for RM-ODP approach. This opens up a useful communication channel between the two groups. The intent is to validate the RASDS to the RM-ODP and to provide feedback to the SC7 WG it its applicability to Space Systems. The JTC 1 / SC 7 chair has agreed to establish an informal liaison w/ CCSDS. SEA, on behalf of CCSDS, has agreed to that liaison and a joint meeting and telecons have been held.

41. PS 41 19 September 2005 Cross Area WG / BOF Issues IAWG needs on-going coordination with MOIMS Information Packaging and Registries (IPR). Much more partnering is occurring with a focus on how to define an information infrastructure (interfaces, specifications, architecture, components and best practices) Recommend that BoF be created for cross-cutting information infrastructure specification (registries, repositories) that gets participation from agency specialists as well as stakeholders IA becoming more important to other groups SLE (data dictionaries, XML schemas, …) XML Standards and Guidelines SANA

42. PS 42 19 September 2005 Cross Area WG / BOF Issues Security is a cross-cutting discipline that needs to be included in many other Areas and WGs. CESG is alerted that other Areas and WG should request support from the Security WG (in addition to the SecWG being proactive). We believe that the mandatory security section in documents will force the other Areas and WG to seek out help. Propose a SecWG overview briefing at the Spring ‘06 meeting opening plenary to cover everyone at one time Security 101 and SecWG initiatives within CCSDS

43. PS 43 19 September 2005 SEA Resolutions to be Sent to CESG and Then to CMC RESOLUTION 1 : SEA-SecWG-R-0509-001 Considering that: 1.The SecWG sent a resolution up requesting that every CCSDS document contain a standard security section. The return flow indicated this was passed. 2.More than a year later we learn that the language was changed (only blue books, resource problems allow provide a waiver, etc). And recognizing that: 1.CCSDS must ensure that security is adequately addressed in our standards, 2.The current wording in the CMC resolution is too weak, The AREA resolves that: The Standard security section should require that include ALL CCSDS documents, not just Blue Books, include the mandatory security section, and … The security section be mandatory and not waived based on resources. ACTION ITEM 1: SEA-SecWG-A-0509-001 Request that the CMC update policy on security section to make it mandatory on all CCSDS documents and to remove simple “resources waiver”. At minimum this should apply to Blue, Orange, and Magenta Books.

44. PS 44 19 September 2005 Outcomes of Earlier SEA Resolutions Sent to CESG ACTION ITEM 1: SEA-SecWG-A-0504-001 Request that the CMC review SecWG scope and requirements for cross support and interoperability with agency security policy experts. ACTION ITEM 1: SEA-SecWG-A-0504-002 Request that the CMC provide adequate resources to the SEA / SecWG to accomplish development of encryption and authentication/integrity standards which are fully adapted to the space community and have been profiled, implemented, and tested before becoming CCSDS recommended standards no later than the end of April 2005. ACTION ITEM 3: SEA-A-0504-001 Request that the CESG develop a clear and unambiguous process for submitting and resolving RIDs no later than the end of May 2005. ACTION ITEM 1: SEA-A-0504-002 Request that the areas that have developed or are developing reference architectures or service interfaces to provide them to the SAWG and work with the SAWG to ensure that they and their cross area interactions are correctly understood and properly documented.

47. PS 47 19 September 2005 SAWG Open Issues 1. The standard “UML for ODP,” which is being developed by a ISO/IEC WG, should be used as a basis for developing the formal model of RASDS. However, both RM-ODP and RASDS are instances of domain specific reference models and there should be a mechanism to develop domain specific reference models in a coherent way. 1. There is no standard that defines what Views and Viewpoints are. 2. We should develop comments that reflect our concerns and deliver them to both SysML and the UML for RM-ODP groups.

48. PS 48 19 September 2005 SAWG Action Items 1. Revise the RASDS document based on the discussion at the meeting ActioneeShames Due date30 October 2005 2.

50. PS 50 19 September 2005 SecWG New Working Items, New BOFs, etc. There is a plan to create a BoF at the CCSDS Spring 2006 meeting that defines the charter of a WG that develops a formal model of space data systems. At least two Agencies (NASA and JAXA) is willing to provide necessary resources to support this BoF/WG.

54. PS 54 19 September 2005 SecWG Progress Achieved Attended and participated in the High Rate Uplink BOF, CisLunar WG, and a splinter group of the SLS participants concerning how the Internet protocols work and can be used. Reviewed the latest incarnation of the Security Architecture document and its relationship with the final version of the RASDS. Area of contention within the Security Architecture revolves around key management issues: architecture is heavily slanted towards public key technologies that may not be universally applicable. Also issues revolving around how to do emergency commanding. More review to occur. Reviewed the security algorithm trade studies Encryption: must use AES-128 w/128-bit key at min; additional algorithms may be used at mission/agency/govt discretion. Authentication/Integrity: dual standards that must be used - Digital Signature Algorithm (DSA) for public key-based authentication - Hash-based Message Authentication Code (HMAC) using SHA-1 for shared secret-based authentication - Other hashing algorithms (e.g., MD5, SHA256, SHA384, UMAC) may be used Discussed the beginning of the Security Policy Framework Guide – attempt a CCSDS re-write of the NIST Guide (800-47) and a starting point and re-affirmed the adaptation of the NIST document for CCSDS use. Again discussed the potential use of the Common Criteria for development of mission Protection Profiles. CNES makes heavy use of the CC but does not produce full-blown PPs. The WG did not want to develop PPs (too much boilerplate, too large, too hard to read, etc) but did agree it makes sense to use the CC as a basis for developing mission security requirements and this will be introduced in the mission planners guide that remains to be written. CNES described their level of security involvement in mission development. CNES has an independent security organization that works hand-in-hand with mission planners to develop the mission security requirements, the threat study, the trade studies, and the security life- cycle. They also discussed the risk analysis tool (available as open source), EBIOS, that they use to develop the mission security requirements. This needs to be examined for potential use by others and maybe to be introduced as a CCSDS recommended practice.
