InteroperabilityStandard Access through Non-Intrusive Mediators

Turning Data into Services; Service Composition

Outcomes of GEOSS Interop. Demos

• The Technology Tools and Methods are Ready for Allications

• Mediated Standardization is a Flexible Design Pattern for SoS

• But the Interfaces are Still Uneven; Networks are Still Fragile

• Users Asked for Adding User Feedback to the Data Flow

Interoperability Stack: Key concept of the Web Connecting Machines and People
