 What REST framework doesn't do is give you machine readable hypermedia formats such as [HAL][hal], [Collection+JSON][collection], [JSON API][json-api] or HTML [microformats] by default, or the ability to auto-magically create fully HATEOAS style APIs that include hypermedia-based form descriptions and semantically labelled hyperlinks. Doing so would involve making opinionated choices about API design that should really remain outside of the framework's scope.
