'''Hypertext Application Language''' ('''HAL''') is an [[Internet Draft]] (a "work in progress") standard convention for defining hypermedia such as links to external resources within [[JSON]] or [[XML]] code. The standard was initially proposed on June 2012 specifically for use with JSON<ref name="rfc4627">{{cite journal|title=JSON Hypertext Application Language|journal=Network Working Group|date=6-7-July 2012|issue=Internet-Draft|url=http://tools.ietf.org/pdf/rfc4627.pdf|format=PDF|accessdate=23 July 2014}}</ref> and has since become available in two variations, each specific to JSON or XML. The two associated [[MIME]] types are media type: application/hal+xml and media type: application/hal+json.<ref>{{cite book|last1=Richardson|first1=Leonard|last2=Ruby|first2=Mike Amundsen ; foreword by Sam|title=RESTful Web APIs|date=2013|publisher=O'Reilly|___location=Sebastopol, CA|isbn=978-1-4493-5806-8|edition=First edition.|accessdate=23 July 2014|chapter=7}}</ref>
