  Reusable Interface Definitions for Constrained RESTful Environments
                     draft-ietf-core-interfaces-08

Abstract

   This document defines a set of Constrained RESTful Environments
   (CoRE) Link Format Interface Descriptions [RFC6690] applicable for
   use in constrained environments.  These include the: Actuator,
   Paramter, Read-only parameter, Sensor, Batch, Linked Batch and Link
   List interfaces.

   The Batch, Linked Batch and Link List interfaces make use of resource
   collections.  This document further describes how collections relate
   to interfaces.

   Many applications require a set of interface descriptions in order
   provide the required functionality.  This document defines the
   concept of function sets to specify this set of interfaces and
   resources.
