Besides specifying the new user interface, supporting material such as system and user documentation have to be created. The paper introduces a model-driven approach to create new user interfaces based on existing service definitions. Additionally, it will be shown how the user interface model can be utilized to automatically generate system and user documentation based on the input and output parameters of the existing services and their documentation.enuser interfacemodel-driven approachmodernizationText/Conference Paper0720-8928
