CHOReVOLUTION in a Nutshell

The Future Internet Opportunity

The Future Internet (FI) represents an age of unprecedented opportunities for social, economic, and business growth thanks to the global scale connectivity of the virtual as well as of the physical world. This indeed opens up a wealth of innovative and revolutionary real-life scenarios, as for instance illustrated by the smarter cities perspectives where envisioned scenarios significantly ease daily human activities and give support for the growth of new markets and employment opportunities. 

The Future Internet Challenge

However, leveraging the FI for the development of innovative software applications remain a challenging task even though major enablers are readily available by ways of service-oriented and cloud computing. It is in particular our vision that enabling the choreography of FI services shall play a significant role in the provisioning of innovative applications. However, existing choreography-based service composition approaches are rather static and are poorly suited to the need of the FI that is a highly dynamic networking environment, further bringing together highly heterogeneous services ranging from Thing- to Business-based services that span different security domains. As a result, the technology is not mature enough for market take-up. 


CHOReVOLUTION adds the automated synthesis of dynamic and secured choreographies to existing choreography technologies. This makes these technologies able to support stringent application requirements in terms of dynamism and cross-organization security.
To meet its objectives, the CHOReVOLUTION project undertakes both research and innovation tasks:
- Research concentrates on choreography modelling, synthesis, adaptation, service bus, security, and cloud;
- Innovation focus on industrial validation, development support and integration platform, and the establishment of a CHOReVOLUTION community and market take-up. CHOReVOLUTION outcomes are assessed by experimenting with new applications in the field of Intelligent Transportation Systems.

The CHOReVOLUTION software will be published under an open source licence and be publicly made available through the OW2 community.

  • Adapter (A): It is used to bind a concrete service to a choreography participant, i.e. a given role in the choreography, when there are interfaces mismatch.
  • Binding Component (BC): A BC bridges the gap between the middleware-level interaction paradigm of a service/thing (e.g., REST or CoAP) and SOAP, which is the middleware-level default interaction paradigm.
  • Coordination Delegates (CDs): CDs coordinate the services interaction, in a fully distributed way, according to the collaboration prescribed by the choreography.
  • Dynamism: in the CHOReVOLUTION context, allows for changes in business goals, as specified at design time, and flexible resource provisioning with support for scalability such as automatic reactions to QoS degradation by cloning or adding virtual machines on the cloud infrastructure.
  • Security Filter (SF): the SF filters the interaction protocol of participant services with respect to different cross-boundary and multi-organisation security and identity requirements.
  • Service (S): A Service is a logical representation of a repeatable business activity that has a specified outcome and may be composed of other services. In general, it is perceived as a “black box” by its consumer
