This chapter discusses the significance of domain application protocols in distributed application design and development. Describing an application as an instance of the execution of a domain application protocol, it shows how we can design RESTful APIs that allow clients to drive the execution of a domain application protocol without binding to the protocol itself. The second half of the chapter provides a step-by-step example of a RESTful procurement application; this application realizes a procurement protocol in a way that requires clients to couple simply to media types and link relations, rather than to the protocol.
