Multi-disciplinary Interoperability• Different interoperability levels -at different
Infrastructures level• Four main infrastructure types
1. Thematic/Community Infrastructures SBA/CoP resources core functionalities
2. Digital Earth (Earth System Science) Infrastructure Earth science resources core functionalities
3. Geospatial Information Infrastructure Geospatial resources core functionalities
4. Distributed Computing Infrastructure Distributed Capacity provision functionalities

Challenges to fill the gap Build on existing (autonomous) capacities
Implement a “system of systems” Build on existing and future information 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
Implement Semantic Interoperability Shift from technical interoperability towards conceptual
composability Avoid tight coupling or strong integrations

Conclusions Multi-disciplinary interoperability is needed to
develop the missing Earth System Science (Digital Earth) infrastructure
Main challenges to fill the gap include: Build on existing (autonomous) capacities Lower the present Entry Barrier for Users and resource
Producers Implement Semantic Interoperability
To advance the present SOA approach by developing the necessary Mediation and Brokering functionalities
Bottom-up and Top-down approaches must be considered to Harmonize the GEO S&T and A&D challenges FP7 EuroGEOSS and EGIDA projects have been working for
that
Low Entry Barrier for SBAs SBAs (and CoPs) systems
Remain autonomous Remain unchanged –no new standard must be
implemented, no new component or service must be implemented or deployed
SBAs (and CoPs) may use their own standards to: describe available spatial resources publish accessible resources
The multi-disciplinary infrastructure must implement all the necessary mediation and brokering
functionalities to interoperate with SBA systems avoiding strong integrations
Implement necessary semantic services to facilitate multi-disciplinary interoperability at the conceptual level
