CHOReOS Innovation
Ultra-Large Scale: Number of to-be-coordinated
services
Size of service base
Wide distribution
Heterogeneity
Dynamics
Load
From static to dynamic domain expert-centric
processes:From service development
to service usage
Blurring boundaries between
domain expert & developer roles
Abstractions & models Reasoning about: composition, interaction
protocols, choreography synthesis and evolution
Dynamic choreography-centric development From domain-expert requirements to
choreography specification
Synthesizing scalable and adaptable choreographies
Service-oriented middleware Sustain load (Grid & Cloud Computing)
Sustain heterogeneity (ESB, P2P)
Sustain network pervasiveness (Internet of Things)
Large-scale deployment & evolution
Governance and V&V support Governance (rules, policies & mechanisms) for V&V
Run-time V&V for inter-organization choreographies
