2. Outline • Interoperability initiatives • ESONET statement and WP2 a) work items • Where we are: inventory of standards and interoperability initiatives • sketch of the application of standards to a generic sensor system • Where we are going: existing systems, to map necessities and drawing recommendations

3. ESONET statement <<The ESONET federation will oversee standards, data management and co-ordinate observatory deployment. Data will be interfaced to national and international data centres.>>

4. WP2 Standardization and interoperability a) workitems • Inventory of existing interoperability concepts as possible candidates for future observatory systems • Inventory of existing sensors and interfaces • Recommendations and roadmap for possible realisation schemes

5. Inventory of standards and interoperabilityinitiatives • Identification and mapping of existing standards • Sensing systems • Communication • Data management • Identification of relevant interoperability initiatives (INSPIRE, GMES, IOOS, GEOSS)

6. Interoperability initiatives • INSPIRE: InfrastructureforSpatialInformation in Europe • GMES: Global monitoringforEnvironment and Security • EuroGOOS, IOOS Data Management and Communications • IEEE Committee on Earth Observations • GEOSS Global Earth Observation System of Systems

7. GEOSS SBAs and Systems

8. Component and servicesRegistrationProcess Done N Component has interface? ESONET or Component Register Component Register Service Y N Uses registered standard? Solution Accepted? SIF recommends solution Work with SIF N Y Y Enter solution in registry Reference registered standard

9. Interoperability of ESONET at largefrom sensor interfaces to data

10. Interoperability & Standards What should be standardised ? Interoperability What can be standardised ? “What few things must be the same so that everything else can be different” Eliot Christian, lead of GEO task AR 06-03
