Service Customization by Variability Modeling

The establishment of service orientation in industry determines the need for efficient engineering technologies that properly support the whole life cycle of service provision and consumption. One challenge is adequate support for service consumers for employing complex services in their individual application context, which becomes particularly important for large-scale enterprise technologies where generic services are designed for reuse in several business scenarios. This paper presents an approach for service customization by model-driven variability management. The variable aspects of the services are explicitly described on the basis of a metamodel. Upon this, service consumers can easily create personalized service variants that properly suit their specific context while the consistency for service invocation is maintained.
