Modeling Resources in a Service-Oriented World

Over the last years, the need to interconnect businesses has significantly affected the Web. The Web has moved constantly from a static source of documents to a dynamic platform for distributed applications. The communication infrastructure of the Web links together applications, e.g. by exposing functionality through Web services in different architectural styles. The current strife between SOA and REST leads one to the issue which approach to choose. Supported by a formal model, we show an integrative way to incorporate service orientation and resource orientation in federated systems as a foundation for future agreements rather than a separation of the approaches.
