Technical Summary

   To enable machine-to-machine communication using 
   REST-style protocols, a standard way to do resource 
   discovery is needed.  The present document defines a 
   link format to enable Web Linking by constrained web 
   servers for describing hosted resources, their attributes 
   and other relationships between links.  A small variation 
   of the HTTP Link Header format defined in RFC5988, the 
   CoRE Link Format is carried as a payload and is assigned 
   an Internet media type.  A well-known URI is defined as a 
   default entry-point for requesting the links to resources
   hosted by a server.
