A model-based service creation platform

This paper presents a middleware platform supporting a modelbased\ud approach to service creation. We observe that the\ud complexity of software services increases. To manage this\ud complexity, to reuse middleware functionality, and to quickly\ud create specific services in an efficient and cost-effective way upon\ud user request, models are used, going towards ‘higher-level’\ud programming. In the Friends project, a service creation\ud environment has been developed that supports the modelling and\ud analysis of services at successive abstraction levels, their actual\ud implementation, and their deployment on a service platform. We\ud focus on the underlying paradigms and report on our\ud implementation
