1.  Introduction

   Version 4 of the vCard specification [RFC6350] defines a new KIND
   property to specify the type of entity that a vCard represents.
   During its work on the base vCard4 specification, the VCARDDAV
   Working Group defined values of "individual", "organization",
   "group", and "location" for the KIND property.  The working group
   considered but then removed a value of "thing" to represent any type
   of physical entity, machine, software application, etc., with the
   expectation that such a value might be defined in a vCard extension.
   This document does not define a generic "thing" value but instead
   defines a more narrow "application" value so that vCards can be used
   to represent software applications.

2.  Meaning

   When the KIND property has a value of "application", the vCard
   represents a software application such as a server, an online service
   (e.g., a chat room), or an automated software bot.  More formally, an
   "application" is functionally equivalent to the 'applicationProcess'
   object class used in the Lightweight Directory Access Protocol
   [RFC4519] as derived from the Open Systems Interconnection model
   [X.521] [X.200].  As one example of the "application" KIND, vCards
   are currently used in the Extensible Messaging and Presence Protocol
   [RFC6120] to represent instant messaging servers that are deployed on
   the network.

   The properties included in an application's vCard apply to one of the
   following:

   o  The application itself (e.g., the FN property might represent the
      friendly name of an application service, the URL property might
      represent a website that contains further information about the
      service, and the ADR, GEO, and TZ properties might represent the
      physical address, geographical location, and time zone of the
      machine where the service is hosted).
