Information Architecture WG: Report of the Spring 2010 Meeting

1. Information Architecture WG:Report of the Spring 2010 Meeting May 6, 2010 Dan Crichton, Chair Steve Hughes (presenting) NASA/JPL

2. Summary Technical Status • Information Architecture WG • Goal: Develop a reference architecture and a formal representation method • Working Group Status: Active _X__ Idle ___ Will be terminated __ • Working Group Summary Situation: • Working Group Summary progress: • Good progress on wrapping up final issues on the registry-repository model • Development of an information service architecture concept paper • Interactions with the Reference Architecture BoF and Super SIG regarding development of a SOA style information architecture • Problems and Issues: • Overlapping meeting times makes cross-coordination difficult

3. Executive Summary • Good discussion on reviewing issues of the Registry Repository reference model • Some updates required after attending the “Boot Camp!” before red book submission • Still addressing issues of how to link CCSDS and ebXML • Several good discussions on the Information Service Architecture and review of the concept and recommendations • Recommendation is to form a Information Service Architecture BoF which will begin working on a charter in London • A collaboration will take place with SM+C to review their common services and MAL for consideration as part of the broader information service architecture and to map it to a common layered model of a CCSDS information system view • Some actions needed by WG chairs to help in the analysis of overlaps (information, service, infrastructure, messaging) layers

4. Progress Achieved • Registry Repository • IA/IPR have agreed on a schedule for release of the registry-repository books • An updated registry repository reference model was distributed to the IPR and IA groups prior to the meeting • Comments provided from NASA; ESA committed to providing comments, but not received yet. • An information model WB was also distributed (as a planned green book), but some discussions of whether we should just point directly to the ebXML RIM • Feedback provided and plans for completing the red book including reviewing the CCSDS procedures to make sure it goes smoothly • A concept paper on the Information Service Architecture as produced along with a presentation. The presentation was given in the IPR/IA and Super SIG groups. It was agreed that a BoF should be created which will eventually include elements from IPR/IA and potentially MOIMS. • Development of a WG charter will help to flush out the work products

5. Schedule • Registry/Repository: Address RIDS and changes to the WB and prepare for red book changes (August 2010) • This will require some re-work • Continue to evolve the Information Service Architecture WB (July 2010) • Distribute to the Super SIG stakeholders • Hold NASA TIM in September 2010 • Begin charter planning for ISA

6. Open Issues • Registry/Repository: Current plan is to publish a magenta book, but there are discussions here (ranging from publish as Green to publish as Blue) • Information Architecture: Continued efforts are needed to coordinate cross-area activity in SOA; suggest CESG direct WGs to help identify overlaps of common services, information models, and messaging

7. Action Items • Send meeting notes, presentations and comments to IAWG • To: Info Arch WG Members • Due: June 1, 2010 • Send ISA concept paper • To: SIG members • Due: July 2010 • Distribute updated registry repository reference architecture • To: IPR and MOIMS members • Due: August 2010

8. Resource Problems • There may not be enough resource commitments from member agencies to achieve deliverables, however, we continue to see increasing involvement • Need to identify overlaps in WGs, in terms of information service architecture, and determine how to best leverage what’s been done and to move it towards a more widely used standard within CCSDS

9. Cross Area WG / BOF Issues • Need to also get to the stakeholders in the other groups who have SOA-related patterns and standards, to work together • SEA, MOIMS and CSS areas in particular need to work together with support from the AD down • Need to combine IPR and IA into the ISA WG in Fall 2010

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

11. New Working Items, New BOFs, etc. • Support the creation of the ISA BoF with direction to identify a charter and to identify its work products as well as how it will integrate existing SOA and information architecture related activities.
