Abstract

   The interfaces of RESTful, hypertext-driven applications consist of
   reusable components such as Internet media types and link relation
   types.  This document defines a simple standard that application
   designers can use to describe the interface of their application in a
   structured way so that other parties can develop interoperable
   clients and servers or reuse the components in their own
   applications.

1.  Introduction

   Representational State Transfer (REST) [15] is an architectural style
   for distributed hypermedia systems.  Over the years, REST has gained
   popularity not only as an approach for large-scale information
   dissemination, but also as the basic principle for designing and
   building Internet-based applications in general.

   In the coming years, the size and scope of the Internet is expected
   to greatly increase as physical-world objects become smart enough to
   communicate over the Internet -- a phenomenon known as the Internet
