 vCard Format Extensions: Representing vCard Extensions Defined by the
     Open Mobile Alliance (OMA) Converged Address Book (CAB) Group

Abstract

   This document defines extensions to the vCard data format for
   representing and exchanging certain contact information.  The
   properties covered here have been defined by the Open Mobile Alliance
   (OMA) Converged Address Book group, in order to synchronize, using
   OMA Data Synchronization, contact fields that were not already
   defined in the base vCard 4.0 specification.

1.  Introduction

   Synchronization of an Open Mobile Alliance Converged Address Book
   [OMA-CAB], using Open Mobile Alliance Data Synchronization [OMA-DS],
   commonly uses vCard as an exchange format between the DS Server and
   the DS Client.  In order to properly perform synchronization of an
   OMA-CAB, the CAB specification defines some CAB contact fields not
   already defined in the vCard base specification.  This document
   reuses the definitions found in the OMA-CAB specification and
   describes them as vCard extensions.  The following sections define
   the necessary Properties and Parameters.

1.1.  A Brief Introduction to the Converged Address Book

   The Converged Address Book (CAB) Enabler provides consistent
   mechanisms to manage contact information both in user-facing
   applications and in support of network-facing activities.  At the
   core of this enabler is a network-based contact repository in which a
   user can store contact information.  That information can be
   retrieved by any CAB-enabled device.  The network-based repository is
   also able to provide specific contact information to other users and
   to keep their copies up to date whenever the information is changed.

   The CAB Enabler provides synchronization of the contact information
   available in the user device(s) with the network-based contact
