Internet-Draft           Common YANG Data Types                 May 2013

1.  Introduction

   YANG [RFC6020] is a data modeling language used to model
   configuration and state data manipulated by the Network Configuration
   Protocol (NETCONF) [RFC6241].  The YANG language supports a small set
   of built-in data types and provides mechanisms to derive other types
   from the built-in types.

   This document introduces a collection of common data types derived
   from the built-in YANG data types.  The derived types are designed to
   be applicable for modeling all areas of management information.  The
   definitions are organized in several YANG modules.  The
   "ietf-yang-types" module contains generally useful data types.  The
   "ietf-inet-types" module contains definitions that are relevant for
   the Internet protocol suite.

   This version of the document adds new type definitions to the YANG
   modules and obsoletes [RFC6021].  For the further details, see the
   revision statement of the YANG modules.
