Supporting Service Versioning - MDE to the Rescue

In the field of Service-Oriented Architecture (SOA), evolution is a key issue given the non-trivial nature of updating widely distributed and heterogeneous systems. In particular, the evolution of a service is expressed through the creation and decommissioning of different service versions during its lifetime. These versions must be aligned with each other in such a way as to allow a service developer to track the various modifications introduced over time and whether the resulting service version is compatible with existing consumers. Having all this in mind, this work aims at define a plan to provide a complete framework to support service evolution by means of Model-Driven Engineering techniques.
