Successful Implementations for SBAs using GEOSS Interoperability Arrangements George Percivall The Open Geospatial Consortium Jay Pearlman, IEEE Nadine Alameh, David Arctur, OGC Hervé Caumont, ERDAS Steve Browdy OMS Tech, Inc., S.J.S. Khalsa, NSIDC GEOSS GEOSS Interoperability Arrangements - From the GEOSS 10 Year Plan Reference Document - • Interoperability through open interfaces – Interoperability specifications agreed to among contributing systems – Access to data and information through service interfaces • Open standards and intellectual property rights – GEOSS adopting standards; agreed upon by consensus, preference to formal international standards – GEOSS will not require commercial or proprietary standards – Multiple software implementations compliant with the open standards should exist – Goal is that at least one of the implementations should be available to all implementers "royalty-free" GEOSS Common Infrastructure (GCI) Standards and Interoperability Forum Standards and Interoperability Forum (SIF) • Purpose: Provide advice, expertise and impartial guidance on issues relating to standards and interoperability for GEOSS. • Goal: Enable ever greater degrees of interoperability among GEOSS components through facilitation, technical analysis, advocacy and education • SIF Activities – Maintains and oversees the GEOSS Standards aind Interoperability Registry (SIR) – Currently conducting GEOSS interoperability assessment GEO Task AR-09-01b Architecture Implementation Pilot • Support SBAs by developing new process and infrastructure components for GCI and the broader GEOSS architecture • Evolutionary Development thru AIP Phases • Demonstrate and document results to inform GEOSS Development progress “fostering interoperability arrangements and common practices for GEOSS” AIP Architecture Elements • Components – Manageable units hardware, software, networks • Services – Methods for components to interact using GEOSS Interoperability Arrangements • Use Cases – Describe what can be done with Services, e.g., Discovery, Access, Workflow, etc. • Scenarios – Meet SBA User needs; accomplished with Use Cases Components Interact thru Services GEOSS Common Infrastructure Main GEO Web Site Registered Community Resources Client Tier Registries GEO Web Portal Community Portals Client Applications Components & Services Standards and Interoperability Best Practices Wiki Mediation Tier GEOSS Clearinghouse User Requirements Community Catalogues Search Brokers Alert Servers Workflow Management Processing Servers Test Facility Access Tier GEONETCast Long Term Archives Access Brokers Sensor Web Model Web Flood Tasking and Product Generation in AIP-2 Aid levels for disaster relief funding can be released within days, in advance of on-site damage assessment.
