Abstract

   This memo defines a the profile of the MIME Content-Type [MIME-DIR] for
   directory information profile for a white pages
   person, to be carried in an application/directory MIME Content-Type. white-pages person object, based on a
   vCard electronic business card. The profile consists definition is independent
   of type definitions (e.g., 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) 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 corresponding format method for including a [VCARD] representation of values that each type is
   allowed to contain.

1. Overview

   The application/directory a
   white-pages directory entry within the MIME Content-Type defined in by
   the [MIME-DIR] is
   used for representing directory information in MIME format. It document.

1. Overview

   The [MIME-DIR] document defines a general framework MIME Content-Type for carrying _type: value_ style holding
   different kinds of directory information. The directory information in the body
   may be based on any of a MIME message, but does not define
   specific types or values. number of directory schemas. This document
   defines a [MIME-DIR] usage profile containing
   the types and corresponding value formats for representing conveying directory
   information about an electronic business card. The profile reflects based on one such schema; that of the vCard (The Electronic Business Card) white-pages type of
   person object.

   The schema is based on the attributes for the person object defined
   in [VCARD].

1.1 The vCard Profile the X.520 and X.521 directory services recommendations. The profile is schema
   has augmented the basic attributes defined as follows, using in the profile registration
   template from Section 8 of [MIME-DIR].

                      vCard Application/Directory Content Type

   Profile name: vcard MIME Directory Profile purpose: To hold vcard information about an electronic
   business card.

   schema was first defined in the [VCARD] document. Hence, this [MIME-
   DIR] profile is referred to as the vCard MIME Directory Profile.

   A directory entry based on this usage profile can include traditional
   directory, white-pages information such as the distinguished name
   used to uniquely identify the entry, a formatted representation of
   the name used for user-interface or presentation purposes, both the
   structured and presentation form of the delivery address, various
   telephone numbers and organizational information associated with the
   entry. In addition, traditional paper business card information such
   as an image of an organizational logo or identify photograph can be
   included in this person object.

   The vCard MIME Directory Profile types: also provides support for
   representing other important information about the person associated
   with the directory entry. For instance, the date of birth of the
   person; an audio clip describing the pronunciation of the name
   associated with the directory entry, or some other application of the
   digital sound; longitude and latitude geo-positioning information
   related to the person associated with the directory entry; date and
   time that the directory information was last updated; annotations
   often written on a business card; Uniform Resource Locators (URL) for
   a website; public key information. The profile also provides support
   for non-standard extensions to the schema. This provides the
   flexibility for implementations to augment the current capabilities
   of the profile in a standardized way. More information about this
   electronic business card format can be found in [VCARD].

2. The vCard Mime Directory Profile Registration

   This profile is identified by the following [MIME-DIR] registration
   template information. Subsequent sections define the profile
   definition.

                      vCard MIME Directory Profile special

   New parameters: TYPE

   Profile special notes: The type-grouping feature of [MIME-DIR] is
   supported by this profile to group related vCard properties about a
   directory entry. For example, vCard properties describing WORK or
   HOME related characteristics MAY be grouped with a unique group
   label.

   The profile permits the use of non-standard types (i.e., those
   identified with the prefix string "X-") as a flexible method for
   implementations to extend the functionality currently defined within
   this profile.

3. MIME Directory Features

   The vCard MIME Directory Profile makes use of many of the features
   defined by [MIME-DIR]. The following sub-sections describe specific
   usage constraints or extensions of these predefined features.

3.1 BEGIN and END Type

   The content entity must MUST begin with the type BEGIN and type with a value of
   VCARD. The content entity MUST end with the END type with a value of
   VCARD.

3.2 NAME Type

   If the NAME type END. There appears within a MIME entity conforming to this
   profile, it's value is no other ordering
   limitations on types the displayable, presentation text associated
   with the source for the vCard, as specified in the SOURCE type.

3.3 PROFILE Type

   If the PROFILE type appears within a MIME entity conforming to this
   profile, it's value must be "VCARD".

3.4 SOURCE Type

   If the SOURCE type appears within a MIME entity conforming to this
   profile, it's value provides information how to find the content entity. source for
   the vCard.

3.5 ENCODING Parameter

   The default transfer encoding for the vCard profile is _8BIT_. "8bit". The
   default transfer encoding can MAY be overridden for an individual type
   value by using the _ENCODING_ "ENCODING" type parameter. The parameter value can
   be reset to either _7BIT_, _BASE64_ "7bit", "base64" or _QUOTED-PRINTABLE_. "quoted-printable". This type
   parameter may MAY be used on any type, unless specified otherwise by the
   profile type.

   The usual line-folding technique described in [MIME-DIR] can be used
   to represent type values consisting of long lines of text. For
   example, individual lines in the content entity are delimited by registration.

                      vCard MIME Directory Profile

3.6 CHARSET Parameter

   The default character set for the
   [RFC 822] line break, which vCard profile is a CRLF sequence (ASCII decimal 13,
   followed by ASCII decimal 10). Long lines of text can "UTF-8". The
   default transfer encoding MAY be split into a
   multiple-line representation overridden for an individual type
   value by using the RFC 822 _folding_ technique.
   That is, wherever there may "CHARSET" type parameter. The parameter value MAY
   be linear white space (NOT simply LWSP-
   chars), a CRLF immediately followed by at least one LWSP-char may
   instead reset to any IANA registered character set. This type parameter
   MAY be inserted. For example the line:

   NOTE:This is a long note that exists used on a long line.

   Can be represented as:

   NOTE:This any type, unless specified otherwise by the profile
   type registration.

3.7 LANGUAGE

   The default language for the vCard profile is a long note
    that exists on a long line. "en-US" (US English).
   The process of moving from this folded multiple-line representation
   of a default language MAY be overridden for an individual type value to its single line representation is called
   _unfolding_. Unfolding is accomplished
   by regarding CRLF immediately
   followed by a LWSP-char as equivalent to using the LWSP-char.

   It is recommended that folding "LANGUAGE" type parameter. The prameter value MAY be limited
   reset to higher-level syntactic
   breaks any IANA registered language. This type parameter MAY be
   used on any type, unless specified otherwise by the profile type
   registration.

3.8 Line Endings

   The usual line-folding technique described in structured components [MIME-DIR] can be used
   to represent type values consisting of the property definition. long lines of text.

   A formatted text line break in a type value, MUST also be specified by a
   (RFC 822) line break, which is a CRLF sequence. However, since the
   CRLF sequence is used to delimit a line, type values with formatted
   line breaks (i.e., multiple lines) MUST be encoded using an
   alternate encoding of either Quoted-Printable or Base64, as defined
   in [RFC 1521]. the Quoted-
   Printable encoding.

   For example, in the Quoted-Printable encoding the multiple lines of
   formatted text are separated with a Quoted-Printable CRLF sequence of
   _=0D_
   "=0D" followed by _=0A_ "=0A" followed by a Quoted-Printable soft line

                vCard Application/Directory Content Type
   break sequence of _=_. "=". Quoted-Printable lines of text must also be
   limited to less than 76 characters. The 76 characters does not
   include the CRLF [RFC 822] line break sequence. For example a
   multiple line LABEL value of:

   Mr. John Q. Public
   123 Main Street
   Any Town, CA 12345

   Would be represented in a Quoted-Printable encoding as:

   LABEL;ENCODING=QUOTED-PRINTABLE:Mr. John Q. Public=0D=0A=
   123 Mail Street=0D=0A=
   Any Town, CA   12345

3.9 Structured Type Values

   Compound property values are delimited by a field delimiter,
   specified by the SEMI-COLON character (ASCII decimal 59). A SEMI-
   COLON in a component of a compound property value must be escaped
   with a Backslash character

   The default character set is _UTF-8_. The default character set can
   be overridden for an individual type value by using the _CHARSET_
   type parameter.

                      vCard MIME Directory Profile

   This type parameter may be used on any profile type.
   However, supports the use type grouping mechanism defined in [MIME-
   DIR]. Grouping of this parameter on some profile related types may not make
   sense.

   The default language is _en-US_ (US English). a useful technique to communicate
   common semantics concerning the properties of a vCard.

4. vCard Features

4.1 VALUE Type Parameter

   The default language
   can be overridden for an individual predefined data type value values specified in [MIME-DIR] have been
   extended by using the
   _LANGUAGE_ type parameter. This type parameter may be used on any vCard profile type. However, the use to include a number of this parameter on some profile value types may not make sense. that
   are specific to this profile.

4.1.1 BINARY

   The default location of the "binary" value type values is inline with the profile
   type. However, for some profile types, such as those specifies that specify
   multimedia values, it is efficient to organize the type value as a
   separate MIME entity. The is inline,
   encoded binary data. This value type parameter _VALUE_ can may be specified to
   override in the _INLINE_ location of PHOTO,
   LOGO, SOUND, and KEY types.

   If inline, encoded binary data is specified, the ENCODING type value. The type value can
   parameter must be specified as being located in a separate MIME entity with the
   _CID_ value. In this case, used to specify the type encoding format.

   The value type is defined by the Content-ID for following notation:

   binchar = <Any character valid in the
   MIME entity containing base64 or quoted-printable
   encoding>
   binary       = *binchar              ;A base64 or quoted-printable
   encoding of the binary information

4.1.2 VCARD

   The "vcard" value type value. In addition, specifies that the type value
   can is another
   vCard. This value type may be specified as being located out on the network within some
   Internet resource with in the _URL_ value. In AGENT type. The value
   type is defined by this case, specification.

4.1.3 PHONE-NUMBER

   The "phone-number" value type specifies that the type value is the Uniform Resource Locator for the Internet resource containing
   the type value. a
   telephone number. This value type parameter may be used on any profile type.
   However, the use of this parameter on some profile types may not make
   sense.

   This profile supports specified in the TEL type.
   The value type grouping mechanism defined in [MIME-
   DIR]. Grouping of related profile types is a useful technique to
   communicate common semantics concerning text value that has the properties semantics of a vCard
   object.

1.3 Delimiter Profile Types

   The following profile types are used to delimit the vCard data within UTC. This value type may be specified in the content TZ type. These types are necessary to completely define

   The format of the
   content offset from UTC is defined by [DATETIME]. The value
   type so that it might be identified is an offset from Coordinated Universal Time (UTC). It is
   specified as a vCard object when
   the content type is positive or negative difference in a persistent form outside units of hours and
   minutes (e.g., +hh:mm). The time is specified as a MIME message.

4.3 Delivery Addressing Profile Types

   These profile types are concerned with information associated with related to the delivery
   addressing or label for the object the vCard object.

   Type name: ADR

   Type purpose: To specify the structured components of the delivery
   address strings of for the individual or resource associated with object the vCard. vCard represents.

   Type encoding: text The default is 8bit. It may also be reset to 7bit or
   quoted-printable.

   Type value: text.

   Type special notes: The type value is a string structured text consisting of a
   sequence of address components (i.e., extended address, street
   address, locality, region, postal code, and country name) separated
   by SEMI-COLON character (ASCII decimal 59) and optionally one or more
   LWSP.

   The usual line-folding technique described in [MIME-DIR] can be used
   to represent type values consisting of long lines of text. However, a
   line break components (i.e., extended address, post office
   box, street address, locality, region, postal code, and country name)
   separated by the SEMI-COLON character in a value MUST be encoded using either Base64 (ASCII decimal 59) and
   optionally one or Quoted-Printable methods. more LWSP.

   The type may include the type parameter _TYPE_ "TYPE" to further qualify the
   usage of specify the
   delivery address. address type. The TYPE parameter values may include:
   _DOM_ include "dom" to
   indicate a domestic delivery address, _INTL_ address; "intl" to indicate an
   international delivery address, _POSTAL_ address; "postal" to indicate a postal
   delivery address, _PARCEL_ address; "parcel" to indicate a parcel delivery address,
   _HOME_ address;
   "home" to indicate a delivery address for a residence, _WORK_ residence; "work" to
   indicate delivery address for a place of work, work; and _PREF_ for "pref" to indicate
   the preferred delivery address when more than one address might be
   specified. These type parameter values may be specified as a
   parameter list (i.e., _TYPE=DOM;TYPE=POSTAL_) "TYPE=dom;TYPE=postal") or as a value list
   (i.e., _TYPE=DOM;POSTAL_). "TYPE=dom,postal"). This type is based on semantics of the
   X.520 geographical and postal addressing attributes. The default is
   _TYPE=INTL;POSTAL;PARCEL;WORK_.
   "TYPE=intl,postal,parcel,work". The default can be overridden to some
   other set of values by specifying one or more alternate values. For
   example, the default can be reset to _TYPE=DOM;POSTAL;WORK;HOME_ "TYPE=dom,postal,work,home" to
   specify a domestic delivery address for postal delivery to a
   residence that is also used for work.

                      vCard Application/Directory Content Type

   Type name: UID

   Type purpose: To specify a value that represents a globally unique
   identifier corresponding to the individual or resource associated
   with the vCard object.

   Type encoding: text.

   Type special notes: The type value can be used as a mechanism to
   relate different vCard objects. Some examples of valid forms of
   unique identifiers would include ISO 9070 formal public identifiers
   (FPI) as defined in [ISO 9070], X.500 distinguished names, machine-
   generated random numbers with a statistically high likelihood of
   being globally unique, and Uniform Resource Locators (URL). If an URL
   is specified, it is suggested that the URL reference a service which
   will produce an updated version of the vCard associated with the
   individual or resource.

   The type may include the MIME Directory Profile
