   JSON Hyper-Schema: A Vocabulary for Hypermedia Annotation of JSON
               draft-handrews-json-schema-hyperschema-02

Abstract

   JSON Schema is a JSON-based format for describing JSON data using
   various vocabularies.  This document specifies a vocabulary for
   annotating JSON documents with hyperlinks.  These hyperlinks include
   attributes describing how to manipulate and interact with remote
   resources through hypermedia environments such as HTTP, as well as
   determining whether the link is usable based on the instance value.
   The hyperlink serialization format described in this document is also
   usable independent of JSON Schema.
