Abstract

REpresentational State Transfer (REST) is the architecture style behind the World Wide Web (WWW), allowing for many desirable quality attributes such as adaptability and interoperability. However, as many process-intensive Web information systems do not make use of REST, they often do not achieve these qualities. This paper addresses this issue by proposing RESTful Business Processes (RESTfulBP), an architectural style that adapts REST principles to Web-based business processes. RESTfulBP views processes and activities as transferrable resources by representing them as process fragments associated with a set of standard operations. Distributed process fragments interoperate by adhering to these operations and exchanging process information. The process information contains basic workflow patterns that are used for dynamic process coordination at runtime. We validate our approach through an industry case study.
