The REST architectural style has made a strong impact on the way Web services are designed, built and also composed. In this talk we take a close look at the way clients interact with them and introduce the notion of RESTful conversation. We show that there many examples of recurring conversation types that can be found on the Web (from small indirect lookups based on hypermedia relationships, to the navigation within the elements of collection resources or the confirmation/cancellation of reserved resources within RESTful atomic distributed transactions). Capturing them helps to raise the abstraction level when modeling RESTful APIs and also provides a novel perspective to study the relationship between business processes and Web resources, or what we call RESTful Business Process Management.
