Information Architecture WG: Report of the Fall 2010 Meeting October 29, 2010 Dan Crichton, Chair Steve Hughes (presenting) NASA/JPL

Summary Technical Status 1.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: Excellent progress in developing a prototype registry reference implementation to support registration of data products, data dictionaries, and other artifacts Good progress in developing the white book and aligning the interfaces with the reference implementation Interactions with the Reference Architecture BoF development of a SOA style information architecture Discussion on coordinated prototype effort between SM+C/IA personnel regarding the directory services Problems and Issues: Overlapping meeting times makes cross-coordination difficult Status:OKCAUTIONPROBLEM Comment: Progress being achieved

Executive Summary Good discussion on reviewing issues of the Registry Repository reference model –The book needs some minor improvements and examples, but is largely in place and consistent with the prototype Demonstration of a CCSDS registry-compliant prototype showed 100K objects ingested now into a PDS registry –Also demonstrated the importance of an info model-driven approach Several good discussions on the Information Service Architecture and review of the concept and recommendations Action to begin to prototype SM+C directory services with CCSDS registry reference model and report progress at next meeting

Progress Achieved The registry reference information model white book has made considerable progress A functioning prototype has been delivered to a customer A draft charter for the Information Services Architecture (ISA) has been drafted and reviewed Good progress in beginning to align with other architectures and WGs draft

Schedule Address RIDS and changes to the WB and prepare for red book submission (January 2011) Begin prototyping efforts with SM+C/JSC Report back at spring meetings on progress in aligning architecture and WG efforts

Open Issues 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 Send meeting notes, presentations and comments to IAWG –To: Info Arch WG Members –Due: December 1, 2010 Distribute updated registry repository reference architecture –To: IPR and MOIMS members –Due: December 15, 2010

Resource/Overlap Problems 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/common approach across CCSDS

Cross Area WG / BOF Issues Need to ensure that WGs are working together towards an integrated CCSDS approach

Resolutions to be Sent to CESG and Then to CMC Recommendation to change IA charter to the Information Services Architecture WG and focus on common information architecture/management/modeling approaches across CCSDS and within the space domain

New Working Items, New BOFs, etc. None
