What is COMPOSE?Provide an IoT enabling ecosystem

Easily and securely develop, deploy, share and maintain services based on Internet-connected smart objects

Use-case driven

Cover the whole service lifecycle

Study and identify new business models and value chains

Promote standardization and adoption

Total Cost: 7.4M Euros; EC contribution: 5.35M

Technical ApproachA Services Objects Market to provide:- Objects service management• Registration, object and interaction virtualization, maintenance, accounting,

knowledge aggregation and dispatching

• Service design and execution environment– SDK to easily develop and deploy services

based on Internet connected Objects– Runtime environment (for both servers and

mobile devices) to dynamically configure and execute services

- Provide an IoT enabling middleware layer– Build on existing and forming technology to provide end-to-end eco-

system for IoT– Distribute system functionalities– Seamless integration with a plethora of objects by abstracting them into

service objects ensuring dependability and traceability
