<p>You keep using that word "REST". I do not think it means what you think it means.</p>

<p>First off, the disclaimer. The name "Django REST framework" was choosen with a view to making sure the project would be easily found by developers. Throughout the documentation we try to use the more simple and technically correct terminology of "Web APIs".</p>
<p>If you are serious about designing a Hypermedia APIs, you should look to resources outside of this documentation to help inform your design choices.</p>
<p>The following fall into the "required reading" category.</p>

<h1 id="building-hypermedia-apis-with-rest-framework">Building Hypermedia APIs with REST framework</h1>
<p>REST framework is an agnositic Web API toolkit. It does help guide you towards building well-connected APIs, and makes it easy to design appropriate media types, but it does not strictly enforce any particular design style.</p>
<h3 id="what-rest-framework-does-provide">What REST framework <em>does</em> provide.</h3>
<p>It is self evident that REST framework makes it possible to build Hypermedia APIs. The browseable API that it offers is built on HTML - the hypermedia language of the web.</p>
<p>REST framework also includes <a href="../api-guide/serializers">serialization</a> and <a href="../api-guide/parsers">parser</a>/<a href="../api-guide/renderers">renderer</a> components that make it easy to build appropriate media types, <a href="../api-guide/fields">hyperlinked relations</a> for building well-connected systems, and great support for <a href="../api-guide/content-negotiation">content negotiation</a>.</p>
<h3 id="what-rest-framework-doesnt-provide">What REST framework <em>doesn't</em> provide.</h3>
<p>What REST framework doesn't do is give you is machine readable hypermedia formats such as <a href="http://www.amundsen.com/media-types/collection/">Collection+JSON</a> by default, or the ability to auto-magically create HATEOAS style APIs. Doing so would involve making opinionated choices about API design that should really remain outside of the framework's scope.</p>
