1.  Introduction

   Smart home is one of vertical applications of Internet of Things
   (IoT).  The deployment of smart home applications and systems often
   requires various types of devices (for example, home appliances) from
   different device manufacturers, and each device requires multiple
   properties and/or methods (for example, switch, mode, etc.)
   supported.

   Now, many consortiums are working on device models to descibe the
   properties and methods of IoT devices, like information model to
   describe the data produced by device, and interaction model to define
   how to interact with device.  However, simply relying on device model
   still cannot guarantee the semantic interoperability.

   Current device information model vocabularies for smart home are
   often tightly coupled to limited number of device manufacturers, thus
   resulting in relatively rigid and static device vocabularies.  The
   static nature of such device vocabularies greatly reduces and, in
   many cases, limits the ability of a smart home service provider to
   introduce new or modify existing device properties and/or methods.

   This document outlines the problems encountered with existing device
   information model vocabularies for smart home, and provides the
   requirement that is necessary to solve the problem.

2.  Problem Statement

   The following points describe aspects of existing smart home device
   vocabularies that are problematic.
