Information Architecture WG:Report of the Spring 2010 Meeting

May 6, 2010

Dan Crichton, Chair

Steve Hughes (presenting)



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
executive summary
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
progress achieved
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
  • 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
open issues
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
action items
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
resource problems
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
cross area wg bof issues
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
new working items new bofs etc
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.
