  4. Three Interoperability phases

  5. Multi-disciplinaryInteroperability EarthSystem Domain Semantics Digital Earth Infrastructure Decision & PolicyMakers Oceanographers Geologists Hydrologists Clinatologists Atmos. Science Oceanography Hydrology Biodiversity Information Systems Geology Geospatial Information Infrastructure • Different interoperability levels -at different Infrastructures level • Fourmaininfrastructuretypes • Thematic/CommunityInfrastructures • SBA/CoP resources core functionalities • Digital Earth (Earth System Science) Infrastructure • Earth science resources core functionalities • Geospatial Information Infrastructure • Geospatial resources core functionalities • Distributed Computing Infrastructure • Distributed Capacity provisionfunctionalities Distributed Computing Infrastructure (s)

  6. Challenges to fill the gap • Build on existing (autonomous) capacities • Implement a “system of systems” • Build on existing and futureinformation systems • Supplementing but not supplanting systems mandates and governance arrangements • Assure a Low Entry Barrier for Users and Resource Providers • Mediate (standard and non-standard capacities) • Interconnect (capacities) and Adapt existing capacities • ImplementSemanticInteroperability • Shift from technical interoperability towards conceptual composability • Avoid tight coupling or strong integrations

  7. Low Entry Barrier Complexity to manage Users Complexity to manage Cyber-Infrastructure BrokeringFramework Complexity to manage Low Entry Barrier Providers
