Abstract

Next generation SOA systems promise to enable an “Internet of Services” (IoS) - an open environment, in which every participant is free to offer and consume services. Such an IoS gives businesses the opportunity to outsource parts of their internal processes and to replace them by using external services. However, businesses must ensure that external services are compatible with their processes and that they can quickly adapt if service offering changes on the market. This raises the need for a process definition language with a formal foundation and well-defined semantics. In this paper, we discuss the suitability of different process definition languages for automatic service composition, show that subject-oriented modeling with PASS is well-suited for this domain, and how automatic service composition is implemented in the Theseus/TEXO project.
