The track Model-based development, Components and Services (MOCS) will be part of SEAA 2017. Two of the major current trends in software engineering are: the increasing emphasis on model-driven engineering, and the increasingly central role of component-based and service-based paradigms in tackling scale and complexity in the development of ever larger and more complex software systems. Whereas model-based development is essentially top-down, component- and service-based development is essentially bottom-up. To combine these paradigms require new methods and tools. The main goal of this track is to provide a forum for researchers and practitioners on model-based development, component-based and service-based software engineering, where they can meet, discuss, exchange and disseminate ideas, problems and results, identify key issues and explore possible solutions and future work.
