Preface to the Fourth International Workshop on Models and Model-Driven Methods for Service Engineering -- 3M4SE 2013

The Fourth International Workshop on Models and Model-driven Methods for Service Engineering -3M4SE 2013- aims at helping the convergence of research on model-driven development and practical application of the model-driven approach in the area of enterprise computing and service engineering. The workshop addresses questions with respect to the requirements on, concepts for, properties of and experience with models and model-driven methods for service engineering in the area of enterprise computing. A special focus has been on the combined application of model-driven and semantic approaches in the different phases of the service lifecycle.
