Information Architecture WG: Report of the Spring 2006 Meeting

1. Information Architecture WG:Report of the Spring 2006 Meeting June 16, 2006 Dan Crichton, Chair NASA/JPL

2. Executive Summary • 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)

3. Progress Achieved • Significant progress has been achieved since the September meeting and we have received and incorporated quite a few comments. We believe getting broader agency review is now critical. • What has also emerged now is the need to define architectural patterns and styles using RASIM concepts for different space domain use cases. • Broader interest in registries now seems to be occurring.

4. Schedule

5. Open Issues • While there exists CCSDS participation, it is still minimal across the agencies. • Many agencies now appear to be discussing the IA architecture concepts so the need is increasing • Many agencies are identifying needs for capabilities such as different registries (metadata, schema, service, etc) • Cross WG coordination is still difficult • WGs run different lengths which makes scheduling tough • Registries work increasing in criticality • Talks beginning on XML schema registries, but the need is broader • Cross agency international space data systems efforts growing their own registry standards (e.g., the International Virtual Observatory Alliance, Planetary Science, etc) • SANA needs it

6. Action Items • Send meeting notes, presentations and comments to IAWG • To: Info Arch WG Members • Due: Due June 30, 2006 • Add new participants to mailing list • To: New Participants • Due: Due June 30, 2006 • Send an updated version of the green book • To: IAWG Members • Due: Due July 1, 2006 • Send Registries White Paper Concept to mailing list • To: IAWG • Due: September 2006

7. Resource Problems • There may not be enough resource commitments from member agencies to achieve deliverables. ESA,CNES and BNSC considered important stakeholders and seem to now be doing more information architecture-related activities.

8. Cross Area WG / BOF Issues • Need 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 • Need to also get to the stakeholders in the other groups who have information architecture concerns/problems.

9. Resolutions to be Sent to CESG and Then to CMC • None

10. New Working Items, New BOFs, etc. • Critical that cross group information infrastructure activities be started and that the experts be engaged.

11. IAWG Summary Technical Status • 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: • Finalizing RASIM Greenbook • Discussed development of best practice documents for applying information architecture concepts/components • Discussed initiation of registry services Problems and Issues: • Availability of agency participants with right skill set is uncertain • Registry services development at risk due to competing priorities and narrow focus Status: OK CAUTION PROBLEM Comment: Need Participation
