+                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.
