DRAFT GEO Architecture and Data CommitteeArchitecture Workshop Hosted by the European Commission At the Joint Research Centre February 2008
Recap of 2007 - Initial Operating Capability for the GEOSS Core Architecture George Percivall, et. al.
GEOSS Core Architecture Initial Operating Capability (IOC) • Core Architecture • GEO Web Portal, Clearinghouse, and Registry • Process to register, discover and use services • GEOSS Interoperability Arrangements • During 2007, GEO ADC guided development of IOC through its core tasks: • AR-07-01 - Enabling Deployment of Architecture • AR-07-02 - Architecture Implementation Pilot • Results demonstrated at EO Summit and GEO-IV
Services Catalogues Core Architecture accesses GEO Web Portal and other Clients searches User searches invokes GEOSS Clearinghouse list of catalogues GEOSS Component, Service registry references accesses contribute to register Standards, Special Arrangements Registries Offerors reference
AI Pilot Milestones - 2007 • Call for Participation (CFP) • CFP Preparation based on RFIs February & March • CFP Release April 13 • CFP Responses Due May 11 • Pilot Kickoff meeting June 5&6 • Hosted at ESA-ESRIN • Deploy, Integrate, Test 4 mo. June to September • Demo Capture Workshop September 10&11 • Core Architecture Implementation Report November
GEO Task AR-07-02GEO Architecture Implementation Pilot - 2007 • Demonstrated effective development process: • CFP, Kickoff, Execution, etc. • Approximately 120 organizations • Established effective communication methods • For international coordination • www.ogcnetwork.net/AIpilot • Produced Screencasts of Initial Operating Capability • www.ogcnetwork.net/AIPdemos • Prepared “Core Architecture Implementation Report”
GEOSS Architecture Status • Architecture validated through ADC core tasks • Deployed, tested and demonstrated in 2007 • Component types and interactions confirmed • Recommendations for Interoperability Arrangements • Consistent with GEOSS Strategic Guidance Document and Tactical Guidance Document
GEOSS Architecture • Initial Operating Capability (IOC) established • 64 Components & 75 Services registered (21 Nov 07) • GEO Web Portals (3), Community Portals (27) and Decision Support Clients (13) for User access to services • Several organizations capable of providing • GEO Web Portal solutions • GEOSS Clearinghouse solutions
GEO Web Portal • Demonstrated that organizations are capable of providing workable GEO Web Portal solutions • Compusult: http://www.geowebportal.org • ESA-FAO: http://www.geoportal.org • ESRI: http://keel.esri.com/Portal • Though visibly similar & meeting basic requirements, the three offer different feature sets. • Cape Town Declaration: “We commit to explore ways and means for the sustained operations of the shared architectural GEOSS components and related information infrastructure.”
GEOSS Architecture - Further Development • Increase collaboration with GEO Committees, Communities of Practice and relevant GEO Tasks. • Increase commitment to Operational requirements to support persistence • Portal, Clearinghouse and other services • Add Sensor Component Types • Task, acquire and process observations • Inter-calibration scenario, e.g., CEOS • Workflow for observation processing and decision support, e.g., Fed Earth Observation (FedEO) pilot
AR-07-02 Task Definition • Task Sheet slightly revised at ADC-5, September 2007 • Architecture Implementation Pilot emphasis retained: Portals, Clearinghouse, Catalogues, and Services • Including sensors interoperability services • Two items added • Persistent Infrastructure for Service Integration • GEOSS User and Architecture Workshops
GEO Architecture Workshop • February 4&5, 2008 • Co-located at JRC Ispra with ADC-6 • Purpose: Consensus building in support of CFP • Topics • Scenario candidates: interactions with UIC & CoP re scenarios • Begin refinement of the CFP-2007 architecture • Sustained operations for information architecture • Other Implementation Report topics

IEEE GEOSS Workshop • The User and the GEOSS Architecture XIV Organized by: Dr. Changyong Cao - NOAA/NESDIS, Washington DC Prof. Al Gasiewski – University of Colorado, Boulder, CO Dr. Siri Jodha Singh Khalsa – University of Colorado NSIDC, Boulder, CO Dr. Jay Pearlman – The Boeing Corporation Mr. Ivan Petiteville – ESA A typical Proceedings includes • Workshop Flyer • Description • Agenda • Briefings • Breakout Session Reports • Conclusions Selected briefings Are recorded and Available on the ICEO Site under Resources (Audio & slide lectures) Demonstrations material And video clips are uploaded To the OGC Web site
Breakout Sessions – User/Developer’s Perspective Sample Questions • What is a user? • What are the needs and concerns for GEOSS from a user perspective? • What are the most important information from GEOSS for user applications? • If the architecture is developed over a number of years, what features should be developed early? • What features are missing that you would like to see included
Breakout Sessions – Summary Findings I • A spectrum of Users • End Users (Top level Decision/policy makers, managers) in need of user friendly information • Researchers more focused on source and quality of data • Accommodate different needs & level of expertise • Users versus Providers • Encourage connectivity between the two and between models and data providers • Iterative, interactive feedback from users & ability to correct errors • Models • Need for interoperable cross-domain models • Improved connection between modeling and observation communities
Breakout Sessions – Summary findings IIEmphasis on Data • Key data characteristics • Discovery, accessibility, distribution, visualization/layering, sharing • Data packaging • Clear documentation – especially when cutting across benefit areas • Standards • Meta-data • Frequently mentioned concerns • Timeliness (from real time to paleo-data) • Security/authentication (access to proprietary data...) • Quality (Trusted source; Quality Assurance and Control; Data lineage) • Continuity of data source • Compatibility • Sharing policies • Data distribution mechanism • Internet vs mobile access (including ad-hoc networking) • Feedback mechanism
Breakout Sessions – Summary Findings III • SoS Architecture key desired characteristics • Offer simple, seamless services • Supports high availability, reliability, security, authentication • Facilitate interoperability • Allows for technology evolution & new technology insertion • Thoughts on interoperability • Focus on connecting systems within a community • Interfaces are abstracted in “wrappers” developed cooperatively by Providers & Users • Include ontology in Interoperability registry • Build a little, test a little: demonstrations, prototypes and pilots are essential
Demos and Pilots • Demonstration of the core architecture • Service registration and discovery process • Application of the architecture to eight societal benefit scenarios • use of the portal candidates • Screencast videos of the demonstrations are available on-line: http://www.ogcnetwork.net/AIPdemos Demo team in Yellowknife, Canada
