Recap of 2007 - Initial Operating Capability for the GEOSS Core Architecture

George Percivall, et. al.

GEOSS Core ArchitectureInitial 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

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-07-02

GEO 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 Engineering Architecture

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

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

Architecture Workshop

• Interactive meeting to develop requirements for GEOSS Architecture developments.

• Results will become part of a Call for Participation in 2008.

• Scenarios identified through collaboration of the GEO UIC and ADC

• Domain-specific GEO Tasks can utilize AIP (AR-07-02) to utilize the GEOSS Core Architecture
