Internet-Draft                    vCard                       March 2009


1.  Introduction

   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.

   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.

2.  Conventions

   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 [RFC2119].

3.  MIME Type Registration

   To:  ietf-types@iana.org

   Subject:  Registration of media type text/vcard

   Type name:  text

   Subtype name:  vcard

   Required parameters:  none

   Optional parameters:  charset

   Encoding considerations:  The "charset" MIME parameter is interpreted
      as defined in [RFC2046], section 4.1.2.  If it is omitted, the
      default encoding is UTF-8 as defined in [RFC3629].

   Security considerations:  See Section 11.

   Interoperability considerations:  The text/vcard media type is
      intended to identify vCard data of any version.  There are older
      specifications of vCard [RFC2426][oldreference_VCARD] still in
      common use.  While these formats are similar, they are not
      strictly compatible.  In general, it is necessary to inspect the
      value of the VERSION property (see Section 7.7.10) for identifying

      the standard to which a given vCard object conforms.

      In addition, the following media types are known to have been used
      to refer to vCard data.  They should be considered deprecated in
      favor of text/vcard.

      *  text/directory

      *  text/directory; type=vcard

      *  text/x-vcard

   Published specification:  draft-ietf-vcarddav-vcardrev-06

   Applications that use this media type:  They are numerous, diverse,
      and include mail user agents, instant messaging clients, address
      book applications, directory servers, customer relationship
      management software, etc.

4.  vCard Format Specification

   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.

Internet-Draft                    vCard                       March 2009


4.1.  Line Delimiting and Folding

   Individual lines within vCard are delimited by the [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.  Content lines SHOULD be folded to a maximum width of 75
   octets.  Multi-octet characters MUST remain contiguous.  The
   rationale for this folding process can be found in [RFC2822], Section
   2.1.1.

   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:

     DESCRIPTION:This is a long description that exists on a long line.

   can be represented as:

     DESCRIPTION:This is a long description
       that exists on a long line.

   It could also be represented as:

     DESCRIPTION:This is a long descrip
      tion that exists o
      n a long line.

   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).

      Note: It is possible for very simple implementations to generate
      improperly folded lines in the middle of a UTF-8 multi-octet
      sequence.  For this reason, implementations SHOULD unfold lines in
      such a way as to properly restore the original sequence.

      Note: Unfolding is done differently than in [RFC2822].  Unfolding
      in [RFC2822] only removes the CRLF, not the space following it.

   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.

4.2.  ABNF Format Definition

   The following ABNF uses the notation of [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:

   contentline  = [group "."] 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.

   group        = "WORK" / "HOME" / iana-token / x-name

   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

   immediately preceeding CRLF should be discarded when reconstructing
   the original line.  Note that this line-folding convention differs
   from that found in [RFC2822], in that the sequence <CRLF><WSP> found
   anywhere in the content indicates a continued line and should be
   removed.

   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.

   The group construct is used to group related properties together.
   For example, groups named "WORK" and "HOME" could be used to
   segregate properties such as telephone number, address, etc.
   Displaying of groups is left entirely up to the application.
   Predefined groups with assigned meaning are listed in Section 12.2.1.
   It is possible to register new groups from IANA.  Unregistered groups
   MAY be used and MUST start with "X-".

   Properties defined in a vCard instance may have multiple values
   depending on the property cardinality.  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.

4.3.  Property Value Escaping

   A property instance may contain one or more values delimited by a
   COMMA character (ASCII decimal 44).  Therefore, a COMMA character in
   a value MUST be escaped with a BACKSLASH character (ASCII decimal
   92), even for properties that don't allow multiple instances (for
   consistency).

   Some properties (e.g.  N and ADR) comprise multiple fields delimited
   by a SEMI-COLON character (ASCII decimal 59).  Therefore, a SEMI-
   COLON in a field of such a "compound" property MUST be escaped with a
   BACKSLASH character.  SEMI-COLON characters in non-compound
   properties MUST NOT be escaped.

   Furthermore, some fields of compound properties may contain a list of
   values delimited by a COMMA character.  Therefore, a COMMA character
   in one of a field's values MUST be escaped with a BACKSLASH
   character, even for fields that don't allow multiple values (for
   consistency).  Compound properties allowing multiple instances MUST
   NOT be encoded in a single content line.

   Finally, newline (ASCII decimal 10) and backslash (ASCII decimal 92)
   characters in values MUST be escaped by prefixing them with a
   backslash character.

   In all other cases, escaping MUST NOT be used.

5.  Property Value Data Types

   Standard value types are defined below.

   valuespec =  text-list
             / URI               ; from Appendix A of [RFC3986]
             / date-list
             / time-list
             / date-time-list
             / boolean
             / integer-list
             / float-list
             / binary
             / utc-offset
             / iana-valuespec

   text-list = *TEXT-LIST-CHAR *("," *TEXT-LIST-CHAR)

   TEXT-LIST-CHAR = "\\" / "\," / "\n"
                 / <any VALUE-CHAR except , or \ or newline>
      ; Backslashes, newlines, and commas must be encoded.
      ; \n or \N can be used to encode a newline.

   date-list = date *("," date)

   time-list = time *("," time)

   date-time-list = date "T" time *("," date "T" time)

   boolean = "TRUE" / "FALSE"

   integer-list = integer *("," integer)

   integer = [sign] 1*DIGIT

   float-list = float *("," float)

   float = [sign] 1*DIGIT ["." 1*DIGIT]

   sign = "+" / "-"

   binary = <A "B" binary encoded string as defined by [RFC2047].>

                    with IANA, as defined in section 12 of this
                    document>

5.1.  TEXT

   "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 Section 6.1.

   Examples for "text":

       this is a text value
       this is one value,this is another
       this is a single value\, with a comma encoded

   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".

   For example a multiple line DESCRIPTION value of:

       Mythical Manager
       Hyjinx Software Division
       BabsCo, Inc.

   could be represented as:

       DESCRIPTION:Mythical Manager\nHyjinx Software Division\n
        BabsCo\, Inc.\n

   demonstrating the \n literal formatted line break technique, the
   CRLF-followed-by-space line folding technique, and the backslash
   escape technique.

5.2.  URI

   "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 [RFC3986].  Note that the value
   of a property of type "uri" is what the URI points to, not the URI
   itself.

   Examples for "uri":

       http://www.example.com/my/picture.jpg
       ldap://ldap.example.com/cn=babs%20jensen

5.3.  DATE, TIME, and DATE-TIME

   "date", "time", and "date-time": Each of these value types is based
   on a subset of the definitions in [ISO.8601.1988] standard.  Multiple
   "date" and "time" values can be specified using the comma-separated
   notation.

   Examples for "date":

       1985-04-12
       1996-08-05,1996-11-11
       19850412

       1996-10-22T14:00:00Z,1996-08-11T12:34:56Z

5.4.  BOOLEAN

   "boolean": The "boolean" value type is used to express boolen values.
   These values are case insensitive.

   Examples:

       TRUE
       false
       True

5.5.  INTEGER

   "integer": The "integer" value type is used to express signed
   integers in decimal format.  If sign is not specified, the value is
   assumed positive "+".  Multiple "integer" values can be specified
   using the comma-separated notation.

   Examples:

       1234567890
       -1234556790
       +1234556790,432109876

5.6.  FLOAT

   "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.

       1000000.0000001
       1.333,3.14

5.7.  BINARY

   "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.

   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 Section 4.1.

5.8.  UTC-OFFSET

   "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.

   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.

5.9.  LANGUAGE-TAG

   "language-tag": A single language tag, as defined in [RFC4646].

6.  Property Parameters

   A property can have attributes associated with it.  These "property
   parameters" contain meta-information about the property or the
   property value.

   Property parameter values that contain the COLON (US-ASCII decimal
   58), SEMICOLON (US-ASCII decimal 59) or COMMA (US-ASCII decimal 44)
   character separators MUST be specified as quoted-string text values.
   Property parameter values MUST NOT contain the DQUOTE (US-ASCII
   decimal 22) character.  The DQUOTE (US-ASCII decimal 22) character is

   used as a delimiter for parameter values that contain restricted
   characters or URI text.  For example:

     EMAIL;PID=8:jdoe@example.com

   Property parameter values that are not in quoted strings are case
   insensitive.

   The general property parameters defined by this memo are defined by
   the following notation:

          vcardparameter = encodingparam
                         / valuetypeparam
                         / languageparam

                                   ; section 12 of this document

          valuetypeparam = "value" "=" valuetype

          valuetype = "uri"        ; URI from Appendix A of [RFC3986]
                     / "text"
                     / "date"
                     / "time"

   recognize.

6.1.  LANGUAGE

   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 [RFC4646].

6.2.  ENCODING

   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.

   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.

   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.

   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.

6.3.  VALUE

   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.

   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.

6.4.  PREF

   The "pref" parameter is optional, and is used to indicate that the
   corresponding instance of a property is preferred by the vCard
   author.  Its value MUST be a strictly positive integer that
   quantifies the level of preferredness.  Lower values correspond to a
   higher level of preferrredness, 1 being most preferred.  The value
   zero MUST NOT be used.

   When the parameter is absent, the default MUST be to interpret the
   property instance as being least preferred.

   Note that the value of this parameter is to be interpreted only in
   relation to values assigned to other instances of the same property
   in the same vCard.  A given value, or the absence of a value, MUST
   NOT be interpreted on its own.

   This parameter MAY be applied to any property that allows multiple
   instances.

6.5.  PID

   The "pid" parameter is used to identify a specific property among
   multiple instances.  It plays a role analogous to the UID property
   (Section 7.7.7) on a per-property instead of per-vCard basis.  It MAY
   appear more than once in a given property.  It MUST NOT appear on
   properties that only may have one instance per vCard.  Its value is
   either a single small integer, or a pair of small integers separated
   by a dot.  Multiple values may be encoded in a single PID parameter
   by separating the values with a comma ",".  See Section 8 for more
   details on its usage.

6.6.  TYPE

   The "type" parameter has multiple, different uses.  In general, it is
   a way of specifying class characteristics of the associated property.
   Most of the time, its value is a comma-separated subset of a pre-

   Special notes:  The content entity MUST begin with the BEGIN property
      with a value of "VCARD".

      The BEGIN property is used in conjunction with the END property to
      delimit an entity containing a related set of properties within an
      text/vcard content-type.  This construct can be used instead of or
      in addition to wrapping separate sets of information inside
      additional MIME headers.  It is provided for applications that
      wish to define content that can contain multiple entities within
      the same text/vcard content-type or to define content that can be
      identifiable outside of a MIME environment.

   Example:

7.1.2.  END

   Purpose:  To denote the end of a syntactic entity within a text/vcard
      content-type.

   Value type:  text

   Cardinality:  (1,1)

   Special notes:  The content entity MUST end with the END type with a
      value of "VCARD".

      The END property is used in conjunction with the BEGIN property to
      delimit an entity containing a related set of properties within an
      text/vcard content-type.  This construct can be used instead of or
      in addition to wrapping separate sets of information inside
      additional MIME headers.  It is provided for applications that
      wish to define content that can contain multiple entities within
      the same text/vcard content-type or to define content that can be
      identifiable outside of a MIME environment.

   Example:

         END:VCARD

7.1.3.  SOURCE

   Purpose:  To identify the source of directory information contained
      in the content type.

   Value type:  uri

   Cardinality:  (0,n)

   Special notes:  The SOURCE property is used to provide the means by
      which applications knowledgable in the given directory service
      protocol can obtain additional or more up-to-date information from
      the directory service.  It contains a URI as defined in [RFC3986]
      and/or other information referencing the vCard to which the
      information pertains.  When directory information is available
      from more than one source, the sending entity can pick what it
      considers to be the best source, or multiple SOURCE properties can
      be included.

   Examples:

      Additional Names) separated by the COMMA character (ASCII decimal
      44).  This property is based on the semantics of the X.520
      individual name attributes.  The property SHOULD be present in the
      vCard object when the name of the object the vCard represents
      follows the X.520 model.

   Examples:

             N:Public;John,Q.;Mr.;Esq.

7.3.  Delivery Addressing Properties

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

7.3.1.  ADR

   Purpose:  To specify the components of the delivery address for the
      vCard object.

   Value type:  A single structured text value, separated by the SEMI-
      COLON character (ASCII decimal 59).

   Cardinality:  (0,n)

   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
      postal code; the country name.  When a component value is missing,
      the associated component separator MUST still be specified.

      The text components are separated by the SEMI-COLON character
      (ASCII decimal 59).  Where it makes semantic sense, individual
      text components can include multiple text values (e.g., a "street"
      component with multiple lines) separated by the COMMA character
      (ASCII decimal 44).

      The property can include the "PREF" parameter to indicate the
      preferred delivery address when more than one address is
      specified.

   Example: In this example the post office box and the extended address
   are absent.

           ADR:;;123 Main Street;Any Town;CA;91921-1234

7.3.2.  LABEL

Internet-Draft                    vCard                       March 2009


   Value type:  A single structured value consisting of two float values
      separated by the SEMI-COLON character (ASCII decimal 59).

   Cardinality:  (0,n)

   Special notes:  This property specifies information related to the
      global position of the object associated with the vCard.  The
      value specifies latitude and longitude, in that order (i.e., "LAT
      LON" ordering).  The longitude represents the location east and
      west of the prime meridian as a positive or negative real number,
      respectively.  The latitude represents the location north and
      south of the equator as a positive or negative real number,
      respectively.  The longitude and latitude values MUST be expressed
      in the [WGS84] reference system.  They MUST be specified as
      decimal degrees and should be specified to six decimal places.
      This will allow for granularity within a meter of the geographical
      position.  The text components are separated by the SEMI-COLON
      character (ASCII decimal 59).  The simple formula for converting
      degrees-minutes-seconds into decimal degrees is:


           decimal = degrees + minutes/60 + seconds/3600.

   Example:

           GEO:37.386013;-122.082932

7.6.2.  ROLE

   Purpose:  To specify information concerning the role, occupation, or
      business category of the object the vCard represents.

   Value type:  A single text value.

   Cardinality:  (0,n)

   Special notes:  This property is based on the X.520 Business Category
      explanatory attribute.  This property is included as an
      organizational type to avoid confusion with the semantics of the
      TITLE property and incorrect usage of that property when the
      semantics of this property is intended.

   Example:

           ROLE:Programmer

7.6.3.  LOGO

   Purpose:  To specify a graphic image of a logo associated with the
      object the vCard represents.

   Encoding:  The encoding MUST be reset to "b" using the ENCODING
      parameter in order to specify inline, encoded binary data.  If the
      value is referenced by a URI value, then the default encoding of
      8bit is used and no explicit ENCODING parameter is needed.

   Value type:  A single value.  The default is binary value.  It can
      also be reset to uri value.  The uri value can be used to specify
      a value outside of this MIME entity.

   Cardinality:  (0,n)

   Special notes:  This property SHOULD include the parameter "TYPE" to
      specify the graphic image format type.  The TYPE parameter value
      MUST be an image media type as specified in [RFC4288].  The full
      media type name, including the "image/" prefix, should be used.
      However, implementations SHOULD be able to handle bare subtypes.

   Example:

7.6.6.  RELATED

   Purpose:  To specify a relationship the individual this vCard
      represents has with another.

   Value type:  A single URI.  It can also be reset to a single text
      value.  The text value can be used to specify textual information.

   Cardinality:  (0,n)

   Special notes:  The TYPE parameter MAY be used to characterize the
      related individual.  The understood types are:

      *  "parent" means that the related individual is the parent of the
         individual this vCard represents.

      *  "child" means the opposite of "parent".

      *  "sibling" means that the two individuals are siblings.

      *  "manager" means that the related individual is the direct
         hierarchical superior (i.e. supervisor or manager) of the
         individual this vCard represents.

      *  "assistant" for an assistant or secretary.

      *  "agent" for a person who will act on behalf of the individual
         or resource associated with the vCard.

      Other types may be registered to IANA as described in
      Section 12.1, and private extensions starting with "X-" may be
      used.

   Examples:

     RELATED;TYPE=manager:urn:uuid:f81d4fae-7dec-11d0-a765-00a0c91e6bf6
     RELATED;TYPE=assistant:http://example.com/directory/jdoe.vcf
     RELATED;TYPE=agent;VALUE=text:Please contact my assistant Jane Doe
      for any inquiries.

   These properties are concerned with additional explanations, such as
   that related to informational notes or revisions specific to the
   vCard.

7.7.1.  CATEGORIES

   Purpose:  To specify application category information about the
      vCard.

   Value type:  One or more text values separated by a COMMA character
      (ASCII decimal 44).

7.7.2.  NOTE

   Purpose:  To specify supplemental information or a comment that is
      associated with the vCard.

   Value type:  A single text value.

   Cardinality:  (0,n)

   Special notes:  The property is based on the X.520 Description
      attribute.

   Example:

           NOTE:This fax number is operational 0800 to 1715
             EST\, Mon-Fri.

7.7.3.  PRODID

   Purpose:  To specify the identifier for the product that created the
      vCard object.

   Type value:  A single text value.

   Cardinality:  (0,1)

   Special notes:  Implementations SHOULD use a method such as that
      specified for Formal Public Identifiers in [ISO9070] or for
      Universal Resource Names in [RFC3406] to assure that the text
      value is unique.

   Example:

           PRODID:-//ONLINE DIRECTORY//NONSGML Version 1//EN

7.7.4.  REV

   Purpose:  To specify revision information about the current vCard.

   Value type:  The default is a single date-time value.  Can also be
      reset to a single date value.

   Cardinality:  (0,1)

   Special notes:  The value distinguishes the current revision of the
      information in this vCard for other renditions of the information.

7.7.5.  SORT-STRING

   Purpose:  To specify the family name or given name text to be used
      for national-language-specific sorting of the FN and N types.

   Value type:  A single text value.

   Cardinality:  (0,1)

   Special notes:  The sort string is used to provide family name or
      given name text that is to be used in locale- or national-
      language- specific sorting of the formatted name and structured
      name types.  Without this information, sorting algorithms could
      incorrectly sort this vCard within a sequence of sorted vCards.
      When this property is present in a vCard, then this family name or
      given name value is used for sorting the vCard.

   Examples: For the case of family name sorting, the following examples
   define common sort string usage with the FN and N properties.

           FN:Rene van der Harten
           N:van der Harten;Rene;J.;Sir;R.D.O.N.
           SORT-STRING:Harten

Internet-Draft                    vCard                       March 2009


7.7.6.  SOUND

   Purpose:  To specify a digital sound content information that
      annotates some aspect of the vCard.  By default this property is
      used to specify the proper pronunciation of the name property
      value of the vCard.

   Encoding:  The encoding MUST be reset to "b" using the ENCODING
      parameter in order to specify inline, encoded binary data.  If the
      value is referenced by a URI value, then the default encoding of
      8bit is used and no explicit ENCODING parameter is needed.

   Value type:  A single value.  The default is binary value.  It can
      also be reset to uri value.  The uri value can be used to specify
      a value outside of this MIME entity.

   Cardinality:  (0,n)

   Special notes:  This property SHOULD include the parameter "TYPE" to
      specify the audio format type.  The TYPE parameter value MUST be
      an audio media type as specified in [RFC4288].  The full media
      type name, including the "audio/" prefix, should be used.
      However, implementations SHOULD be able to handle bare subtypes.

   Example:

   SOUND;TYPE=audio/basic;VALUE=uri:CID:JOHNQPUBLIC.part8.
    19960229T080000.xyzMail@example.com

   SOUND;TYPE=audio/basic;ENCODING=b:MIICajCCAdOgAwIBAgICBEUwDQYJK

    ljYXRpb25zIENvcnBvcmF0aW9uMRwwGgYDVQQLExNJbmZvcm1hdGlvbiBTeXN0
    <...the remainder of "B" encoded binary data...>

7.7.7.  UID

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

   Value type:  A single URI value.

   Cardinality:  (0,1)

   Special notes:  This property is used to uniquely identify the object
      that the vCard represents.  The "uuid" URN namespace defined in
      [RFC4122] is particularly well-suited to this task, but other URI
      schemes MAY be used.

Internet-Draft                    vCard                       March 2009


   Example:

           UID:urn:uuid:f81d4fae-7dec-11d0-a765-00a0c91e6bf6

7.7.8.  CLIENTPIDMAP

   Purpose:  To give a global meaning to a local PID source identifier.

   Value type:  A semicolon-separated pair of values.  The first field
      is a small integer corresponding to the second field of a PID
      parameter instance.  The second field is a URI.  The "uuid" URN
      namespace defined in [RFC4122] is particularly well-suited to this
      task, but other URI schemes MAY be used.

   Cardinality:  (0,n)

   Special notes:  PID source identifiers (the source identifier is the
      second field in a PID parameter instance) are small integers that
      only have significance within the scope of a single vCard
      instance.  Each distinct source identifier present in a vCard MUST
      have an associated CLIENTPIDMAP.  See Section 8 for more details
      on the usage of CLIENTPIDMAP.

      PID source identifiers MUST be strictly positive.  Zero is not
      allowed.

      As a special exception, the PID parameter MUST NOT be applied to
      this property.

   Example:

     TEL;PID=3.1,4.2:tel:+1-555-555-5555
     EMAIL;PID=4.1,5.2:jdoe@example.com
     CLIENTPIDMAP:1;urn:uuid:3df403f4-5924-4bb7-b077-3c711d9eb34b
     CLIENTPIDMAP:2;urn:uuid:d89c9c7a-2e1b-4832-82de-7e992d95faa5

7.7.9.  URL

   Purpose:  To specify a uniform resource locator associated with the
      object that the vCard refers to.

   Cardinality:  (0,n)

   Value type:  A single uri value.

   Example:

           URL:http://example.org/restaurant.french/~chezchic.html

7.7.10.  VERSION

   Purpose:  To specify the version of the vCard specification used to
      format this vCard.

   Value type:  A single text value.

   Cardinality:  (1,1)

   Special notes:  The property MUST be present in the vCard object.
      The value MUST be "4.0" if the vCard corresponds to this
      specification.

   Example:

           VERSION:4.0

7.8.  Security Properties

   These properties are concerned with the security of communication
   pathways or access to the vCard.

7.8.1.  CLASS

   Purpose:  To specify the access classification for a vCard object.

   Value type:  A single text value.

   Cardinality:  (0,1)

   Special notes:  An access classification is only one component of the
      general security model for a directory service.  The
      classification attribute provides a method of capturing the intent
      of the owner for general access to information described by the
      vCard object.

      Predefined values are:

      PUBLIC:  This vCard MAY be shared with anyone.

      PRIVATE:  This vCard MUST NOT be shared.  It MAY be exported if
         explictly authorized and requested by the creator.

      CONFIDENTIAL:  This vCard MAY be shared with allowed users or
         systems.  The exact confidentiality level is site-specific and
         out of scope for the vCard specification.

   Examples:

           CLASS:PUBLIC

           CLASS:PRIVATE

           CLASS:CONFIDENTIAL

7.8.2.  KEY

   Purpose:  To specify a public key or authentication certificate
      associated with the object that the vCard represents.

   Encoding:  The encoding MUST be reset to "b" using the ENCODING
      parameter in order to specify inline, encoded binary data.  If the
      value is a text value, then the default encoding of 8bit is used
      and no explicit ENCODING parameter is needed.

   Value type:  A single value.  The default is binary.  It can also be
      reset to uri value.  The uri value can be used to specify a value
      outside of this MIME entity.  In this case, the key's media type
      is obtained externally (e.g. with the HTTP Content-Type header)
      instead of with the TYPE parameter.

   Cardinality:  (0,n)

   Special notes:  This property SHOULD include the parameter "TYPE" to
      specify the public key or authentication certificate format.  The
      TYPE parameter value MUST be a media type as specified in
      [RFC4288].

   Examples:

   KEY;VALUE=uri:http://www.example.com/keys/jdoe

   KEY;TYPE=application/pgp-keys;ENCODING=b:mQGiBEbEPUsRBACBF0RSIN

Internet-Draft                    vCard                       March 2009


   Purpose:  To specify the URI for a user's busy time in a vCard
      object.

   Value type:  A single URI value.

   Cardinality:  (0,n)

   Special notes:  Where multiple FBURL properties are specified, the
      default FBURL property is indicated with the PREF parameter.  The
      FTP or HTTP type of URI points to an iCalendar object associated
      with a snapshot of the last six weeks of the user's busy time
      data.  If the iCalendar object is represented as a file or
      document, it's file type should be "ifb".

   Examples:

     FBURL;PREF=1:http://www.example.com/busy/janedoe
     FBURL:FTP://ftp.example.com/busy/project-a.ifb

7.9.2.  CALADRURI

   Purpose:  To specify the location to which an event request should be
      sent for the user.

   Value type:  A single URI value.

   Cardinality:  (0,n)

   Special notes:  Where multiple CALADRURI properties are specified,
      the default CALADRURI property is indicated with the PREF
      parameter.

   Example:

     CALADRURI;PREF=1:mailto:janedoe@example.com
     CALADRURI:http://example.com/calendar/jdoe

7.9.3.  CALURI

      default CALURI property is indicated with the PREF parameter.  The
      property should contain a URI pointing to an iCalendar object
      associated with a snapshot of the user's calendar store.  If the
      iCalendar object is represented as a file or document, it's file
      type should be "ics".

   Examples:

     CALURI:ftp://ftp.example.com/calA.ics

7.10.  Extended Properties and Parameters

   The properties and parameters defined by this document can be
   extended.  Non-standard, private properties and parameters with a
   name starting with "X-" may be defined bilaterally between two
   cooperating agents without outside registration or standardization.

8.  Synchronization

   vCard data often needs to be synchronized between devices.  In this
   context, synchronization is defined as the intelligent merging of two
   representations of the same object. vCard 4.0 includes mechanisms to
   aid this process.

8.1.  Mechanisms

   Two mechanisms are available: the UID property is used to match
   multiple instances of the same vCard, while the PID parameter is used
   to match multiple instances of the same property.

   The term "matching" is used here to mean recognizing that two
   instances are in fact representations of the same object.  For
   example, a single vCard that is shared with someone results in two
   vCard instances.  After they have evolved separately, they still
   represent the same object, and therefore may be matched by a
   synchronization engine.

8.1.1.  Matching vCard Instances

   vCard instances for which the UID properties (Section 7.7.7) are
   equivalent MUST be matched.  Equivalence is determined as specified
   in [RFC3986], Section 6.

   In all other cases, vCard instances MAY be matched at the discretion
   of the synchronization engine.

8.1.2.  Matching Property Instances

   Property instances belonging to unmatched vCards MUST NOT be matched.

   Property instances whose name (e.g.  EMAIL, TEL, etc.) is not the
   same MUST NOT be matched.

   Property instances whose name is CLIENTPIDMAP are handled separately
   and MUST NOT be matched.  The synchronization MUST ensure that there
   is consistency of CLIENTPIDMAPs among matched vCard instances.

   Property instances belonging to matched vCards, whose name is the
   same, and whose maximum cardinality is 1 MUST be matched.

   Property instances belonging to matched vCards, whose name is the
   same, and whose PID parameters match MUST be matched.  See
   Section 8.1.3 for details on PID matching.

   In all other cases, property instances MAY be matched at the
   discretion of the synchronization engine.

8.1.3.  PID Matching

   Two PID values for which the first fields are equivalent represent
   the same local value.

   Two PID values representing the same local value and for which the
   second fields point to CLIENTPIDMAP properties whose second field
   URIs are equivalent (as specified in [RFC3986], Section 6) also
   represent the same global value.

   PID parameters for which at least one pair of their values represent
   the same global value MUST be matched.

   In all other cases, PID parameters MAY be matched at the discretion
   of the synchronization engine.

   For example, PID value "5.1", in the first vCard below, and PID value

     CLIENTPIDMAP:2;urn:uuid:3eef374e-7179-4196-a914-27358c3e6527
     END:VCARD

8.2.  Example

8.2.1.  Creation

   The following simple vCard is first created on a given device.

     BEGIN:VCARD
     VERSION:4.0
     UID:urn:uuid:4fbe8971-0bc3-424c-9c26-36c3e1eff6b1
     FN:J. Doe
     EMAIL;PID=1.1:jdoe@example.com
     CLIENTPIDMAP:1;urn:uuid:53e374d9-337e-4727-8803-a1e9c14e0556
     END:VCARD

   This new vCard is assigned the UID
   "urn:uuid:4fbe8971-0bc3-424c-9c26-36c3e1eff6b1" by the creating
   device.  The EMAIL property is assigned PID 1, and this PID is given
   global context by associating it with
   "urn:uuid:53e374d9-337e-4727-8803-a1e9c14e0556", which represents the
   creating device.  The FN property has no PID because it is forbidden
   by its maximum cardinality of 1.

8.2.2.  Initial Sharing

   This vCard is shared with a second device.  Upon inspecting the UID
   property, the second device understands that this is a new vCard
   (i.e. unmatched) and thus the synchronization results in a simple
   copy.

8.2.3.  Adding and Sharing a Property

   A new phone number is created on the first device, then the vCard is
   shared with the second device.  This is what the second device
   receives:

     BEGIN:VCARD
     VERSION:4.0
     UID:urn:uuid:4fbe8971-0bc3-424c-9c26-36c3e1eff6b1
     FN:J. Doe
     EMAIL;PID=1.1:jdoe@example.com
     TEL;PID=1.1:tel:+1-555-555-5555
     CLIENTPIDMAP:1;urn:uuid:53e374d9-337e-4727-8803-a1e9c14e0556
     END:VCARD

   Upon inspecting the UID property, the second device matches the vCard
   it received to the vCard that it already has stored.  It then starts
   comparing the properties of the two vCards in same-named pairs.

   The FN properties are matched automatically because their maximum
   cardinality is 1.  Since the property value is the same, no update
   takes place.

   The EMAIL properties are matched because the PID parameters have the
   same global value.  Since the property value is the same, no update
   takes place.

   The TEL property in the new vCard is not matched to any in the stored
   vCard because no property in the stored vCard has the same name.
   Therefore, this property is copied from the new vCard to the stored
   vCard.

   The CLIENTPIDMAP property is handled separately by the
   synchronization engine.  It ensures that it is consistent with the
   stored one.  If it was not, the results would be up to the
   synchronization engine, and thus undefined by this document.

8.2.4.  Simultaneous Editing

   A new email address and a new phone number are added to the vCard on
   each of the two devices, and then a new synchronization event
   happens.  Here are the vCards that are communicated to each other:

     END:VCARD

   On the first device, the same PID source identifier (1) is reused for
   the new EMAIL and TEL properties.  On the second device, a new source
   identifier (2) is generated, and a corresponding CLIENTPIDMAP
   property is created.  It contains the second device's identifier,
   "urn:uuid:1f762d2b-03c4-4a83-9a03-75ff658a6eee".

   The new EMAIL properties are unmatched on both sides since the PID
   global value is new in both cases.  The sync thus results in a copy
   on both sides.

   Although the situation appears to be the same for the TEL properties,
   in this case the synchronization engine is particularly smart and
   matches the two new TEL properties even though their PID global
   values are different.  Note that in this case, the rules of section
   Section 8.1.2 state that two properties may be matched at the
   discretion of the synchronization engine.  Therefore, the two
   properties are merged.

   All this results in the following vCard which is stored on both
   devices:

8.2.5.  Global Context Simplification

   The two devices finish their synchronization procedure by simplifying
   their global contexts.  Since they haven't talked to any other
   device, the following vCard is for all purposes equivalent to the
   above.  It is also shorter.

     BEGIN:VCARD
     VERSION:4.0
     UID:urn:uuid:4fbe8971-0bc3-424c-9c26-36c3e1eff6b1

     CLIENTPIDMAP:1;urn:uuid:53e374d9-337e-4727-8803-a1e9c14e0556
     END:VCARD

   The details of global context simplification are unspecified by this
   document.  They are left up to the synchronization engine.  This
   example is merely intended to illustrate the possibility, which
   investigating would be, in the authors' opinion, worthwhile.

9.  Formal Grammar

   The following formal grammar is provided to assist developers in
   building parsers for the vCard.

   This syntax is written according to the form described in [RFC5234],
   but it references just this small subset of [RFC5234] literals:

11.  Security Considerations

   o  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).

   o  vCards can carry cryptographic keys or certificates, as described
      in Section 7.8.2.

   o  Section 7.8.1 specifies a desired security classification policy
      for a particular vCard.  That policy is not enforced in any way.

   o  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.

   o  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 Section 7.7.9 SHOULD BE specified.  In
      addition, the "REV" type described in section Section 7.7.4 can be
      specified to indicate the last time that the vCard data was
      updated.

12.  IANA Considerations

12.1.  Registering New vCard Elements

   This section defines the process for registering new or modified
   vCard elements (i.e. properties, parameters, value data types, and
   values) with IANA.

Internet-Draft                    vCard                       March 2009


12.1.1.  Registration Procedure

   The IETF will create a mailing list, vcard@ietf.org [1], which can be
   used for public discussion of vCard element proposals prior to
   registration.  Use of the mailing list is strongly encouraged.  The
   IESG will appoint a designated expert who will monitor the
   vcard@ietf.org [1] mailing list and review registrations.

   Registration of new vCard elements MUST be reviewed by the designated
   expert and published in an RFC.  A Standard Tracks RFC is REQUIRED
   for the regisration of new value data types that modify existing
   properties.  A Standard Tracks RFC is also REQUIRED for registration
   of vCard elements that modify vCard elements previously documented in
   a Standard Tracks RFC.

   The registration procedure begins when a completed registration
   template, defined in the sections below, is sent to
   vcard@ietf.org [1] and iana@iana.org [2].  The designated expert is
   expected to tell IANA and the submitter of the registration within
   two weeks whether the registration is approved, approved with minor
   changes, or rejected with cause.  When a registration is rejected
   with cause, it can be re-submitted if the concerns listed in the
   cause are addressed.  Decisions made by the designated expert can be
   appealed to the IESG Applications Area Director, then to the IESG.
   They follow the normal appeals procedure for IESG decisions.

12.1.2.  Vendor Namespace

   The vendor namespace is used for vCard elements associated with
   commercially available products.  "Vendor" or "producer" are
   construed as equivalent and very broadly in this context.

   A registration may be placed in the vendor namespace by anyone who
   needs to interchange files associated with the particular product.
   However, the registration formally belongs to the vendor or
   organization handling the vCard elements in the namespace being
   registered.  Changes to the specification will be made at their
   request, as discussed in subsequent sections.

   vCard elements belonging to the vendor namespace will be
   distinguished by the "VND-" prefix.  That may be followed, at the
   discretion of the registrant, by either a vCard element name from a
   well-known producer (e.g., "VND-MUDPIE") or by an IANA-approved
   designation of the producer's name that is followed by a vCard
   element designation (e.g., "VND-BIGCOMPANY-MUDPIE").

   While public exposure and review of vCard elements to be registered
   in the vendor namespace is not required, using the vcard@ietf.org [1]

   mailing list for review is strongly encouraged to improve the quality
   of those specifications.  Registrations in the vendor namespace may
   be submitted directly to the IANA.

12.1.3.  Registration Template for Groups

   A group is defined by completing the following template.

   Group name:  The name of the group.

   Purpose:  The purpose of the group.  Give a short but clear
      description.

   Description:  Any special notes about the group, how it is to be
      used, etc.

   Allowed Properties:  List of properties that may be placed inside the
      group.

   Example(s):  One or more examples of instances of the value type
      needs to be specified.

12.1.4.  Registration Template for Properties

   A property is defined by completing the following template.

   Property name:  The name of the property.

   Purpose:  The purpose of the property.  Give a short but clear
      description.

   Value type:  Any of the valid value types for the property value
      needs to be specified.  The default value type also needs to be
      specified.

   Property parameters:  Any of the valid property parameters for the
      property MUST be specified.

   Groups:  List of already-existing groups whose allowed properties
      list must be updated by adding this new property.

   Description:  Any special notes about the property, how it is to be
      used, etc.

   Format definition:  The ABNF for the property definition needs to be
      specified.

      longer supported.

   o  In the N property, additional names are now subsumed into the
      given names list.

A.3.  New Properties and Parameters

   o  The KIND, GENDER, LANG, DDAY, BIRTH, and DEATH properties have
      been added.

   o  [RFC2739], which defines the FBURL, CALADRURI, CAPURI, and CALURI
      properties, has been merged in.

   o  [RFC4770], which defines the IMPP property, has been merged in.

   o  The "work", "home", and "uri" TYPE parameter values for the EMAIL
      property have been added.
