Abstract

   This memo defines the profile of the MIME Content-Type [MIME-DIR] for
   directory information for a white-pages person object, based on a
   vCard electronic business card. The profile definition is independent
   of any particular directory service or protocol. The profile is
   defined for representing and exchanging a variety of information
   about an individual (e.g., formatted and structured name and delivery
   addresses, email address, multiple telephone numbers, photograph,
   logo, audio clips, etc.). The directory information used by this
   profile is based on the attributes for the person object defined in
   the X.520 and X.521 directory services recommendations. The profile
   also provides the method for including a [VCARD] representation of a
   white-pages directory entry within the MIME Content-Type defined by
   the [MIME-DIR] document.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY" and "OPTIONAL" in this
   document are to be interpreted as described in [RFC 2119].
