     Resource Discovery in Constrained RESTful Environments (CoRE)
       using the Constrained RESTful Application Language (CoRAL)
                    draft-hartke-t2trg-coral-reef-02

Abstract

   This document explores how the Constrained RESTful Application
   Language (CoRAL) might be used for two use cases in Constrained
   RESTful Environments (CoRE): CoRE Resource Discovery, which allows a
   client to discover the resources of a server given a host name or IP
   address, and CoRE Resource Directory, which provides a directory of
   resources on many servers.

1.  Preamble

   This document explores how CoRE Resource Discovery [RFC6690] and CoRE
   Resource Directory [I-D.ietf-core-resource-directory] might look like
   if based on CoRAL [I-D.hartke-t2trg-coral].  The exploration is done
   in the style of a self-contained specification.
