    This document defines the vCard data format 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.).

<section title="Introduction">
  <t>Note: This draft contains much of the same text as 2425 and 2426 which may
    not be correct. Those two RFCs have been merged and the structure of this
    draft is what's new. Some vCard-specific suggestions have been added, but
    for the most part this is still very open. But we'd like to get feedback on
    the structure mostly so that it may be fixed.</t>
  <t>Electronic address books have become ubiquitous. Their increased presense
    on portable, connected devices as well as the diversity of platforms
    exchanging contact data call for a standard. This memo defines the vCard
    format, which allows the capture and exchange of information normally stored
    within an address book or directory
    application.</t>

<section title="vCard Format Specification">

  <t>The text/vcard MIME content type (hereafter known as "vCard") contains
    contact information, typically pertaining to a single contact or group of
    contacts.  The content consists of one or more lines in the format given
    below.</t>

  <section title="Line Delimiting and Folding" anchor="folding">

    <t>Individual lines within vCard are delimited by the <xref
        target="RFC2822"/> line break, which is a CRLF sequence (ASCII decimal
      13, followed by ASCII decimal 10). Long logical lines of text can be split
      into a multiple-physical-line representation using the following folding
      technique. After generating a content line, lines longer than 75
      characters SHOULD be folded.</t>

    <t>A logical line MAY be continued on the next physical line anywhere
      between two characters by inserting a CRLF immediately followed by a
      single white space character (space, ASCII decimal 32, or horizontal tab,
      ASCII decimal 9).  At least one character must be present on the folded
      line. Any sequence of CRLF followed immediately by a single white space
      character is ignored (removed) when processing the content type.  For
      example the line:</t>
    <figure><artwork>
  DESCRIPTION:This is a long description that exists on a long line.
    </artwork></figure>
    <figure>
      <preamble>can be represented as:</preamble>
      <artwork>
  DESCRIPTION:This is a long description
   that exists on a long line.
      </artwork>
    </figure>
    <figure>
      <preamble>It could also be represented as:</preamble>
      <artwork>
  DESCRIPTION:This is a long descrip
   tion that exists o
   n a long line.
      </artwork>
    </figure>

    <t>The process of moving from this folded multiple-line representation of a
      property definition to its single line representation is called unfolding.
      Unfolding is accomplished by regarding CRLF immediately followed by a
      white space character (namely HTAB ASCII decimal 9 or SPACE ASCII decimal
      32) as equivalent to no characters at all (i.e., the CRLF and single white
      space character are removed).</t>

    <t>Folding is done after any content encoding of a type value. Unfolding is
      done before any decoding of a type value in a content line.</t>

  </section>

  <section title="ABNF Format Definition">

    <t>The following ABNF uses the notation of <xref target="RFC5234"/>, which
      also defines CRLF, WSP, DQUOTE, VCHAR, ALPHA, and DIGIT.  After the
      unfolding of any folded lines as described above, the syntax for a line of
      this content type is as follows:</t>

    <figure>
      <artwork>
   contentline  = name *(";" param) ":" value CRLF
      ; When parsing a content line, folded lines MUST first
      ; be unfolded according to the unfolding procedure
      ; described above.
      ; When generating a content line, lines longer than 75
      ; characters SHOULD be folded according to the folding
      ; procedure described above.

   name         = x-name / iana-token

   iana-token   = 1*(ALPHA / DIGIT / "-")
      ; identifier registered with IANA

   x-name       = "x-" 1*(ALPHA / DIGIT / "-")
      ; Names that begin with "x-" or "X-" are
      ; reserved for experimental use, not intended for released
      ; products, or for use in bilateral agreements.

   param        = param-name "=" param-value *("," param-value)

   param-name   = x-name / iana-token

   param-value  = ptext / quoted-string

   ptext  = *SAFE-CHAR

   value = *VALUE-CHAR
         / valuespec      ; valuespec defined in section 5.8.4<!--TODO: update ref-->

   quoted-string = DQUOTE *QSAFE-CHAR DQUOTE

   NON-ASCII    = %x80-FF
      ; use restricted by charset parameter
      ; on outer MIME object (UTF-8 preferred)

   QSAFE-CHAR   = WSP / %x21 / %x23-7E / NON-ASCII
      ; Any character except CTLs, DQUOTE

   SAFE-CHAR    = WSP / %x21 / %x23-2B / %x2D-39 / %x3C-7E / NON-ASCII
      ; Any character except CTLs, DQUOTE, ";", ":", ","

   VALUE-CHAR   = WSP / VCHAR / NON-ASCII
      ; any textual character
      </artwork>
    </figure>

    <t>A line that begins with a white space character is a continuation of the
      previous line, as described above. The white space character and
      immediately preceeding CRLF should be discarded when reconstructing the
      original line. Note that this line-folding convention differs from that
      found in <xref target="RFC2822"/>, in that the sequence
      <CRLF><WSP> found anywhere in the content indicates a
      continued line and should be removed.</t>

    <t>Property names and parameter names are case insensitive (e.g., the
      property name "fn" is the same as "FN" and "Fn"). Parameter values MAY be
      case sensitive or case insensitive, depending on their definition.</t>

    <t>Each property defined in a vCard instance MAY have multiple values. The
      general rule for encoding multi-valued properties is to simply create a
      new content line for each value (including the property name).  However,
      it should be noted that some value types support encoding multiple values
      in a single content line by separating the values with a comma ",".  This
      approach has been taken for several of the content types defined below
      (date, time, integer, float), for space-saving reasons.</t>

  </section>

  <section title="Value Types">

    <t>Lists of values are delimited by a list delimiter, specified by the COMMA
      character (ASCII decimal 44). A COMMA character in a value MUST be escaped
      with a BACKSLASH character (ASCII decimal 92).</t>

    <t>Compound type 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 (ASCII
      decimal 92).</t>

    <t>Standard value types are defined below.</t>

    <t>Some specific notes on the value types and formats:</t>

    <t>"text": The "text" value type should be used to identify values that
      contain human-readable text. The character set in which the text is
      represented is controlled by the "charset" MIME type parameter. Note that
      there is no way to override this parameter on a per-property basis. As for
      the language, it is controlled by the "language" property parameter
      defined in <xref target="parameters"/>.</t>

    <figure>
      <preamble>Examples for "text":</preamble>
      <artwork>
    this is a text value
    this is one value,this is another
    this is a single value\, with a comma encoded
      </artwork>
    </figure>

    <t>A formatted text line break in a text value type MUST be represented as
      the character sequence backslash (ASCII decimal 92) followed by a Latin
      small letter n (ASCII decimal 110) or a Latin capital letter N (ASCII
      decimal 78), that is "\n" or "\N".</t>

        escape technique.</postamble>
    </figure>
    
    <t>"uri": The "uri" value type should be used to identify values that are
      referenced by a URI (including a Content-ID URI), instead of encoded
      in-line. These value references might be used if the value is too large,
      or otherwise undesirable to include directly. The format for the URI is as
      defined in <xref target="RFC3986"/>. Note that the value of a property of
      type "uri" is what the URI points to, not the URI itself.</t>

    <t>"float": The "float" value type is used to express real numbers.  If sign
      is not specified, the value is assumed positive "+". Multiple "float"
      values can be specified using the comma-separated notation.</t>

    <t>"binary": The "binary" value type specifies that the type value is
      inline, encoded binary data. This value type can be specified in the
      PHOTO, LOGO, SOUND, and KEY types.</t>

    <t>If inline encoded binary data is specified, the ENCODING type parameter
      MUST be used to specify the encoding format. The binary data MUST be
      encoded using the "B" encoding format. Long lines of encoded binary data
      SHOULD BE folded to 75 characters using the folding method defined in
      <xref target="folding"/>.</t>

    <t>"vcard": The "vcard" value type specifies that the type value is another
      vCard. This value type can be specified in the AGENT property. The value type
      is defined by this specification. Since each of the type declarations
      within the vcard value type are being specified within a text value
      themselves, they MUST be terminated with the backslash escape sequence
      "\n" or "\N", instead of the normal newline character sequence CRLF. In
      addition, any COMMA character (ASCII decimal 44), SEMI-COLON character
      (ASCII decimal 59) and COLON character (ASCII decimal 58) MUST be escaped
      with the BACKSLASH character (ASCII decimal 92). For example, with the
      AGENT property a value would be specified as:</t>

    <figure>
      <artwork>
    AGENT:BEGIN:VCARD\nFN:Joe Friday\nTEL:+1-919-555-7878\n
     TITLE:Area Administrator\, Assistant\n EMAIL\;TYPE=INTERN\n
     ET:jfriday@host.com\nEND:VCARD\n
      </artwork>
    </figure>

    <t>"phone-number": The "phone-number" value type specifies that the type
      value is a telephone number. This value type can be specified in the TEL
      type. The value type is a text value that has the special semantics of a
      telephone number as defined in <xref target="CCITT.E163.1988"/> and <xref
        target="CCITT.X121.1988"/>.</t>

    <t>"utc-offset": The "utc-offset" value type specifies that the type value
      is a signed offset from UTC. This value type can be specified in the TZ
      type.</t>

    <t>The value type is an offset from Coordinated Universal Time (UTC). It is
      specified as a positive or negative difference in units of hours and
      minutes (e.g., +hh:mm). The time is specified as a 24-hour clock. Hour
      values are from 00 to 23, and minute values are from 00 to 59. Hour and
      minutes are 2-digits with high order zeroes required to maintain digit
      count. The extended format for ISO 8601 UTC offsets MUST be used. The
      extended format makes use of a colon character as a separator of the hour
      and minute text fields.</t>

         languageparm = "language" "=" Language-Tag
             ; Language-Tag is defined in section 2.1 of RFC 4646
      </artwork>
    </figure>

    <t>The "language" property parameter is used to identify data in multiple
      languages.  There is no concept of "default" language, except as specified
      by any "Content-Language" MIME header parameter that is present.  The
      value of the "language" property parameter is a language tag as defined in
      Section 2 of <xref target="RFC4646"/>.</t>

    <t>The "encoding" property parameter is used to specify an alternate
      encoding for a value.  If the value contains a CRLF, it must be encoded,
      since CRLF is used to separate lines in the content-type itself.
      Currently, only the "b" encoding is supported.</t>

    <t>The "b" encoding can also be useful for binary values that are mixed with
      other text information in the body part (e.g., a certificate).  Using a
      per-value "b" encoding in this case leaves the other information in a more
      readable form. The encoded base 64 value can be split across multiple
      physical lines by using the line folding technique described above.</t>

    <t>The Content-Transfer-Encoding header field is used to specify the
      encoding used for the body part as a whole. The "encoding" property
      parameter is used to specify an encoding for a particular value (e.g., a
      certificate).  In this case, the Content-Transfer-Encoding header might
      specify "8bit", while the one certificate value might specify an encoding
      of "b" via an "encoding=b" property parameter.</t>

    <t>The Content-Transfer-Encoding and the encodings of individual properties
      given by the "encoding" property parameter are independent of one another.
      When encoding a text/vcard body part for transmission, individual
      property encodings are performed first, then the entire body part is
      encoded according to the Content-Transfer-Encoding.  When decoding a
      text/vcard body part, the Content-Transfer-Encoding is decoded first,
      and then any individual properties with an "encoding" property parameter
      are decoded.</t>

    <t>The "value" parameter is optional, and is used to identify the value type
      (data type) and format of the value.  The use of these predefined formats
      is encouraged even if the value parameter is not explicity used.  By
      defining a standard set of value types and their formats, existing parsing
      and processing code can be leveraged. The predefined data type values MUST
      NOT be repeated in COMMA separated value lists except within the N,
      NICKNAME, ADR and CATEGORIES properties.</t>

    <t>Including the value type explicitly as part of each property provides an
      extra hint to keep parsing simple and support more generalized
      applications.  For example a search engine would not have to know the
      particular value types for all of the items for which it is searching.
      Because the value type is explicit in the definition, the search engine
      could look for dates in any item type and provide results that can still
      be interpreted.</t>

          <t hangText='Special notes:'>The structured type value consists of a
            sequence of address components. The component values MUST be
            specified in their corresponding position. The structured type value
            corresponds, in sequence, to the post office box; the extended
            address (e.g. apartment or suite number); the street address; the
            locality (e.g., city); the region (e.g., state or province); the

          <t>The text components are separated by the SEMI-COLON character

            component with multiple lines) separated by the COMMA character
            (ASCII decimal 44).</t>
          <t>The type can include the type parameter "TYPE" to specify the
            delivery address type. The TYPE parameter values can include
            "home" to indicate a delivery address for a residence; "work" to
            indicate delivery address for a place of work; and "pref" to
            indicate the preferred delivery address when more than one address
            is specified. These type parameter values can be specified as a
            parameter list (i.e., "TYPE=home;TYPE=pref") or as a value list

<section title="Security Considerations" anchor="security_considerations">
  <t>
    <list style="symbols">
      <t>Internet mail is subject to many well known security attacks,
        including monitoring, replay, and forgery. Care should be taken by
        any directory service in allowing information to leave the scope of
        the service itself, where any access controls can no longer be
        guaranteed.  Applications should also take care to display directory
        data in a "safe" environment (e.g., PostScript-valued types).</t>
      <t>vCards can carry cryptographic keys or certificates, as described
        in <xref target="oldsection_3_7_2"/>.</t>
      <t><xref target="oldsection_3_7_1"/> specifies a desired security
        classification policy for a particular vCard. That policy is not
        enforced in any way.</t>
      <t>The vCard objects have no inherent authentication or privacy, but
        can easily be carried by any security mechanism that transfers MIME
        objects with authentication or privacy. In cases where threats of
        "spoofed" vCard information is a concern, the vCard SHOULD BE
        transported using one of these secure mechanisms.</t>
      <t>The information in a vCard may become out of date. In cases where
        the vitality of data is important to an originator of a vCard, the
        "URL" type described in <xref target="oldsection_3_6_8"/> SHOULD BE
        specified. In addition, the "REV" type described in section <xref
          target="oldsection_3_6_4"/> can be specified to indicate the last
        time that the vCard data was updated.</t>
