Composing Services for Third-party Service Delivery

By Ingo Weber, Alistair Barros, Norman May, Jörg Hoffmann and Tomasz Kaczmarek


This paper proposes a model-based technique for lowering the entrance barrier for service providers to register services with a marketplace broker, such that the service is rapidly configured to utilize the broker’s local service delivery management components. Specifically, it uses process modeling for supporting the execution steps of a service and shows how service delivery functions (e.g. payment points) “local ” to a service broker can be correctly configured into the process model. By formalizing the different operations in a service delivery function (like payment or settlement) and their allowable execution sequences (full payments must follow partial payments), including crossfunction dependencies, it shows how through tool support, the non-technical user can quickly configure service delivery functions in a consistent and complete way. 1
