  1. The Interoperability Process Pilot Projects (IP3) Stefano Nativi nativi@imaa.cnr.it GEO Architecture & Data Committee 23 May 2008

  2. Content • Origins and goals • 2007 accomplishments • 2008 activities & evolution of IP3 framework • The Model Web • Schedule • Summary & Conclusions

  3. AR-07-01 Task Description • Prototype and validate the implementation of the “Core” GEOSS infrastructure (registries, Clearinghouse, Web Portal) and the processes for contributing and linking systems using the Interoperability Process Pilot Projects.

  4. Origins and Goals of the IP3 In 2006 the GEO Architecture and Data Committee produced a document outlining the “Process for reaching interoperability arrangements” The “Interoperability Process Pilot Project” (IP3) was conceived as a way to begin implementing the GEOSS infrastructure and testing the GEOSS interoperability process A series of projects involving several initially identified GEOSS components was initiated, with the aim of producing a suite of demonstrations for the GEO Summit in November.

  5. Sources • The ADC identified four areas as sources for the pilot projects. • This selection was based on • the desire to involve diverse disciplines • commitments of representatives from the disciplines to actively support the process • Recommendations for additional communities to participate are welcome

  6. Interoperability Process Pilot Project (IP3) Status • Report on 2007 IP3 activities now available • Plan for IP3-2008 submitted as Position Paper to Architecture Workshop under Biodiversity area • But will involve other disciplines as well

  7. The Challenge Utilization of earth observation data for cross-disciplinary basic and applied research requires infrastructure that supports diverse data sources The key to GEOSS’ utility and effectiveness is the implementation of interoperability process for integrating data and information systems Interoperability must be addressed not only through conceptual solutions but through prototypes and demonstration of functionality

  11. Evolution of IP3 Framework We will develop additional multi-disciplinary use cases where Users interact with a Geo-portal to submit queries Query is passed to Catalog service able to distribute the query against the following standard resource types: International Standard (OGC CS-W, WMS, WCS) Community Standards (THREDDS/OPeNDAP, GBIF, MerSea SeaDataNet CDI) The discovered and downloaded datasets are ingested into a model server The model server generates output which is served through a standard resource server (becoming searchable)

  13. The Multidisciplinary Interoperability Process • Registering a newdisciplinarycomponent: • Resource provider registers component which instantiates well-known services (standard / best practice) • The infrastructure catalog component discovers the new service instance and associates specific mediation and access capabilities with it • The infrastructure catalog register is updated adding the new registered resource and the new mediation functionalities -where needed

  15. Model Interoperabililty Simulation models are generally built in isolation and do not easily interoperate with others Result: lost opportunities to address important questions Barriers to interoperability are both technical and cultural For IP3 we will develop and register model interoperability arrangements along with specific mediation solutions and possibly recommendations for new standards.

  16. The Model Web initiative • Improve existing models • Create new models • Increase model interoperability or Model A Model G Model B or Dataset 1 Model C Dataset 3 Portal Model D Dataset 2 Portal Model F Dataset 4 Model E Model Web Gary Geller NASA JPL California Institute of Technology

  17. Model Web: 5-10+ Year Vision • Distributed network of interoperating models (and datasets and sensors) • Using Service-Oriented Architecture • Data format and terminology issues resolved • Multi-disciplinary scope • Grows organically within framework of broad goals and data exchange standards • Models and datasets maintained, operated, and served independently • Web access provided to researchers, managers, public…
