Ontology-based change management of composite services

As services in an SOA can be composed of lower level services, there will exist dependencies between services. Changing services can impact other services in the SOA and a lot of manual service management tasks are required. Our goal is to create a method for analyzing change effects of service adaptations within an SOA. More specific, we study: which services are affected when a certain service is adapted (dependencies), how the services are affected when a certain service is adapted (effects), and what is the best way to deal with this service adaptation (advice). We take an ontological approach to solve the problem and test this approach by building a prototype (tool).
