Abstract—Service dependency management in serviceoriented component platforms is described with languages, which cannot be easily adapted to domain-specific requirements. This prevents the development of language concepts, which are more suitable for the cognitive space and intuition of domain experts than general-purpose languages. We use a model-driven approach to create an extensible language supporting the creation of new language concepts. With this approach, languages for service dependency management can be extended to have the desired concepts and expressiveness.
