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.

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] (Freed, N. and N. Borenstein, “Multipurpose Internet Mail Extensions (MIME) Part Two: Media Types,” November 1996.), section 4.1.2. If it is omitted, the default encoding is UTF-8 as defined in [RFC3629] (Yergeau, F., “UTF-8, a transformation format of ISO 10646,” November 2003.).
Security considerations:
See Section 11 (Security Considerations).
Interoperability considerations:
The text/vcard media type is intended to identify vCard data of any version. There are older specifications of vCard [RFC2426] (Dawson, F. and T. Howes, “vCard MIME Directory Profile,” September 1998.)[oldreference_VCARD] (Internet Mail Consortium, “vCard - The Electronic Business Card Version 2.1,” September September.) 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 7.7.9 (VERSION)) 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:

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.



 TOC 

4.1.  Line Delimiting and Folding

Individual lines within vCard are delimited by the [RFC2822] (Resnick, P., “Internet Message Format,” April 2001.) 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] (Resnick, P., “Internet Message Format,” April 2001.), 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.

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.



 TOC 

4.2.  ABNF Format Definition

The following ABNF uses the notation of [RFC5234] (Crocker, D. and P. Overell, “Augmented BNF for Syntax Specifications: ABNF,” January 2008.), 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  = 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

   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

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 [RFC2822] (Resnick, P., “Internet Message Format,” April 2001.), 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.

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.

5.  Property Value Data Types

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).

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).

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].>

   date = date-fullyear ["-" date-month ["-" date-mday]]

   date-fullyear = 4DIGIT

   date-month = 2DIGIT      ;01-12

   date-mday = 2DIGIT       ;01-28, 01-29, 01-30, 01-31
                            ;based on month/year

   time = time-hour [":" time-minute [":" time-second [time-secfrac]]]
           [time-zone]

   time-hour = 2DIGIT       ;00-23

   time-minute = 2DIGIT     ;00-59

   time-second = 2DIGIT     ;00-60 (leap second)

   time-secfrac = "," 1*DIGIT

   time-zone = "Z" / time-numzone

   time-numzome = sign time-hour [":"] time-minute

   utc-offset = ("+" / "-") time-hour ":" time-minute

   iana-valuespec = <a publicly-defined valuetype format, registered
                     with IANA, as defined in section 12 of this
                     document>


 TOC 

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 (LANGUAGE).

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.



 TOC 

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] (Berners-Lee, T., Fielding, R., and L. Masinter, “Uniform Resource Identifier (URI): Generic Syntax,” January 2005.). 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


 TOC 

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] (International Organization for Standardization, “Data elements and interchange formats - Information interchange - Representation of dates and times,” June 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

Examples for "time":

    10:22:00
    102200
    10:22:00.33
    10:22:00.33Z
    10:22:33,11:22:00
    10:22:00-08:00

Examples for "date-time":

    1996-10-22T14:00:00Z
    1996-08-11T12:34:56Z
    19960811T123456Z
    1996-10-22T14:00:00Z,1996-08-11T12:34:56Z


 TOC 

5.4.  BOOLEAN

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

Examples:

    TRUE
    false
    True


 TOC 

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


 TOC 

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.

Examples:

    20.30
    1000000.0000001
    1.333,3.14


 TOC 

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 (Line Delimiting and Folding).



 TOC 

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.



 TOC 

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:

  FN;PID=8:Jane Doe

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
                      / uidparam

       encodingparam = "encoding" "=" encodingtype

       encodingtype = "b"       ; from [RFC2047]
                  / iana-token  ; registered as described in
                                ; section 12 of this document

       valuetypeparam = "value" "=" valuetype

       valuetype = "uri"        ; URI from Appendix A of [RFC3986]
                  / "text"
                  / "date"
                  / "time"
                  / "date-time" ; date time
                  / "integer"
                  / "boolean"
                  / "float"
                  / x-name
                  / iana-token  ; registered as described in
                                ; section 12 of this document

       languageparam = "language" "=" Language-Tag
           ; Language-Tag is defined in section 2.1 of RFC 4646

       uidparam = "uid" "=" URI  ; from Appendix A of [RFC3986]

Applications MUST ignore x-param and iana-param value they don't recognize.



 TOC 

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] (Phillips, A. and M. Davis, “Tags for Identifying Languages,” September 2006.).



 TOC 

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.



 TOC 

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.



 TOC 

6.4.  PID

The "pid" parameter is used to uniquely identify the property. It plays a role analogous to the UID property (Section 7.7.7 (UID)) on a per-property instead of per-vCard basis. It MUST NOT appear more than once in a given property, and SHOULD be present if synchronization is to be used. See Section 8 (Synchronization). Its value is a small integer.



 TOC 

6.5.  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-defined enumeration. In this document, the following properties make use of this parameter: PHOTO, ADR, LABEL, TEL, EMAIL, IMPP, LOGO, MEMBER, SOUND, and KEY.

7.  vCard Properties

What follows is an enumeration of the standard vCard properties.



 TOC 

7.1.  General Properties



 TOC 

7.1.1.  BEGIN

Purpose:
To denote the beginning of a syntactic entity within a text/vcard content-type.
Value type:
text
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:
      BEGIN:VCARD



 TOC 

7.1.2.  END

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



 TOC 

7.1.3.  SOURCE

Purpose:
To identify the source of directory information contained in the content type.
Value type:
uri
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] (Berners-Lee, T., Fielding, R., and L. Masinter, “Uniform Resource Identifier (URI): Generic Syntax,” January 2005.) 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:
  SOURCE:ldap://ldap.example.com/cn=Babs%20Jensen,%20o=Babsco,%20c=US

  SOURCE:http://directory.example.com/addressbooks/jdoe/
   Jean%20Dupont.vcf



 TOC 

7.1.4.  NAME

Purpose:
To identify the displayable name of the directory entity to which information in the vCard pertains.
Value type:
text
Special notes:
The NAME property is used to convey the display name of the entity to which the directory information pertains. Its value is the displayable, presentation text associated with the source for the vCard, as specified in the SOURCE property.
Example:
      NAME:Babs Jensen's Contact Information



 TOC 

7.1.5.  KIND

Purpose:
To specify the kind of object the vCard represents.
Value type:
A single text value.
Special notes:
The value may be one of: "individual" for a single person, "group" for a group of people, "org" for an organization, an x-name or an iana-token. If this property is absent, "individual" MUST be assumed as default.
Example:

This represents someone named Jane Doe working in the marketing department of the North American division of ABC Inc.

      BEGIN:VCARD
      VERSION:4.0
      KIND:individual
      FN:Jane Doe
      ORG:ABC\, Inc.;North American Division;Marketing
      END:VCARD

This represents the department itself, commonly known as ABC Marketing.

      BEGIN:VCARD
      VERSION:4.0
      KIND:org
      FN:ABC Marketing
      ORG:ABC\, Inc.;North American Division;Marketing
      END:VCARD

 TOC 

7.2.2.  N

Purpose:
To specify the components of the name of the object the vCard represents.
Value type:
A single structured text value. Each component can have multiple values.
Special note:
The structured property value corresponds, in sequence, to the Family Name, Given Name, Additional Names, Honorific Prefixes, and Honorific Suffixes. The text components are separated by the SEMI-COLON character (ASCII decimal 59). Individual text components can include multiple text values (e.g., multiple 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;Quinlan;Mr.;Esq.

          N:Stevenson;John;Philip,Paul;Dr.;Jr.,M.D.,A.C.P.



 TOC 

7.2.3.  NICKNAME

Purpose:
To specify the text corresponding to the nickname of the object the vCard represents.
Value type:
One or more text values separated by a COMMA character (ASCII decimal 44).
Special note:
The nickname is the descriptive name given instead of or in addition to the one belonging to a person, place, or thing. It can also be used to specify a familiar form of a proper name specified by the FN or N properties.
Examples:
          NICKNAME:Robbie

          NICKNAME:Jim,Jimmie



 TOC 

7.2.4.  PHOTO

Purpose:
To specify an image or photograph information that annotates some aspect of 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 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.
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] (Freed, N. and J. Klensin, “Media Type Specifications and Registration Procedures,” December 2005.). The full media type name, including the "image/" prefix, should be used. However, implementations SHOULD be able to handle bare subtypes.
Example:
    PHOTO;VALUE=uri:http://www.example.com/pub/photos
     /jqpublic.gif


    PHOTO;ENCODING=b;TYPE=image/jpeg:MIICajCCAdOgAwIBAgICBEUwDQYJKo

 TOC 

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).
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 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 (i.e., "TYPE=home,pref"). This type is based on semantics of the X.520 geographical and postal addressing attributes. The default is "TYPE=work".

Berners-Lee, “Hypertext Transfer Protocol -- HTTP/1.1,” June 1999.), Section 14.4, i.e. as the value of an Accept-Language HTTP header. This lets one specify preference among languages. Note that any SEMI-COLON character (ASCII decimal 59) must be escaped.
Example:
    LANG:fr,en\;q=0.9



 TOC 

7.5.  Geographical Properties

These properties are concerned with information associated with geographical positions or regions associated with the object the vCard represents.



 TOC 

7.5.1.  TZ

Purpose:
To specify information related to the time zone of the object the vCard represents.
Value type:
The default is a single utc-offset value. It can also be reset to a single text value.
Special notes:
The type value consists of a single value.

Type examples:

        TZ:-05:00

        TZ;VALUE=text:-05:00; EST; Raleigh/North America
        ;This example has a single value, not a structure text value.


 TOC 

7.5.2.  GEO

Purpose:
To specify information related to the global positioning of the object the vCard represents.
Value type:
A single structured value consisting of two float values separated by the SEMI-COLON character (ASCII decimal 59).
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] (National Imagery and Mapping Agency, “Department of Defense World Geodetic System 1984, Third Edition,” January 2000.) 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


 TOC

 TOC 

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.
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


 TOC 

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.
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] (Freed, N. and J. Klensin, “Media Type Specifications and Registration Procedures,” December 2005.). The full media type name, including the "image/" prefix, should be used. However, implementations SHOULD be able to handle bare subtypes.

Example:

        LOGO;VALUE=uri:http://www.example.com/pub/logos/abccorp.jpg

 TOC 

7.6.4.  AGENT

Purpose:
To specify information about another person who will act on behalf of the individual or resource associated with the vCard.
Value type:
The default is a single URI value. It can also be reset to a single text value. The text value can be used to specify textual information.
Special notes:
This property typically is used to specify an area administrator, assistant, or secretary for the individual associated with the vCard. A key characteristic of the AGENT property is that it represents somebody or something that is separately addressable.

Examples:

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

  AGENT:http://example.com/directory/jdoe.vcf

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.
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

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.
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] (Freed, N. and J. Klensin, “Media Type Specifications and Registration Procedures,” December 2005.). 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

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


 TOC 

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.
Special notes:
The type is used to uniquely identify the object that the vCard represents. The "uuid" URN namespace defined in [RFC4122] (Leach, P., Mealling, M., and R. Salz, “A Universally Unique IDentifier (UUID) URN Namespace,” July 2005.) is particularly well-suited to this task, but other URI schemes MAY be used.
This property MUST NOT appear more than once in a given vCard, and MUST be present if synchronization is to be used. See Section 8 (Synchronization).
The PID parameter MUST NOT be applied to this property.

Example:

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


 TOC 

7.7.8.  URL

Purpose:
To specify a uniform resource locator associated with the object that the vCard refers to.
Value type:
A single uri value.

Example:

        URL:http://www.swbyps.restaurant.french/~chezchic.html


 TOC 

7.7.9.  VERSION

Purpose:
To specify the version of the vCard specification used to format this vCard.
Value type:
A single text value.
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


 TOC 

7.8.  Security Properties

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



 TOC 

7.8.1.  CLASS

Purpose:
To specify the access classification for a vCard object.
Value type:
A single text value.
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.

Examples:

        CLASS:PUBLIC

        CLASS:PRIVATE

        CLASS:CONFIDENTIAL


 TOC 

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 text value. The text value can be used to specify a text key.
Special notes:
The property can also include the parameter TYPE to specify the public key or authentication certificate format. This parameter should specify an IANA registered public key or authentication certificate format. It can also specify a non-standard format.
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] (Freed, N. and J. Klensin, “Media Type Specifications and Registration Procedures,” December 2005.).

Example:

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

7.9.  Calendar Properties

These properties are further specified in [RFC2739] (Small, T., Hennessy, D., and F. Dawson, “Calendar Attributes for vCard and LDAP,” January 2000.).



 TOC 

7.9.1.  FBURL

Purpose:
To specify the URI for a user's busy time in a vCard object.
Value type:
A single URI value.
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:http://www.example.com/busy/janedoe
  FBURL:FTP://ftp.example.com/busy/project-a.ifb



 TOC 

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.
Special notes:
Where multiple CALADRURI properties are specified, the default CALADRURI property is indicated with the PREF parameter.
Example:
  CALADRURI;PREF:mailto:janedoe@example.com
  CALDARURI:http://example.com/calendar/jdoe



 TOC 

7.9.3.  CALURI

Purpose:
To specify the URI for a user's calendar in a vCard object.
Value type:
A single URI value.
Special notes:
Where multiple CALURI properties are specified, the 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;PREF:http://cal.example.com/calA
  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.



 TOC 

8.1.  Mechanisms

Two vCards for which the UID properties (Section 7.7.7 (UID)) are equivalent MUST be considered representations of the same object. Equivalence is determined as specified in [RFC3986] (Berners-Lee, T., Fielding, R., and L. Masinter, “Uniform Resource Identifier (URI): Generic Syntax,” January 2005.), Section 6. A missing UID property MUST NOT be considered equivalent to any other. Hence, the UID property SHOULD be present if synchronization is to be used.

Pairs of properties, one from each of a pair of vCards representing the same object, having equivalent names and PID parameter values MUST be considered representations of the same object. A missing PID parameter MUST NOT be considered equivalent to any other. Hence, the PID parameter SHOULD be present if synchronization is to be used.

It is expected that a synchronization engine will exploit such property associations by e.g. overwriting the destination property value and parameters with the source destination property value and parameters. The particular merging strategy is out of scope for this document.



 TOC 

8.2.  Example

Two vCards are to by synchronized:

  BEGIN:VCARD
  VERSION:4.0
  UID:urn:uuid:77a01597-0603-40f3-8138-36deca8618da
  FN;PID=1:Jane Doe
  EMAIL;PID=1:jdoe1@example.com
  EMAIL;PID=2:jdoe2@example.com
  END:VCARD
  BEGIN:VCARD
  VERSION:4.0
  UID:urn:uuid:77a01597-0603-40f3-8138-36deca8618da
  FN;PID=1:Jane Doe
  EMAIL;PID=1:jdoe3@example.com
  EMAIL;PID=3:jdoe4@example.com
  END:VCARD

Assuming the first one is the source and the other is the destination, a synchronization engine may produce the following merged vCard:

  BEGIN:VCARD
  VERSION:4.0
  UID:urn:uuid:77a01597-0603-40f3-8138-36deca8618da
  FN;PID=1:Jane Doe
  EMAIL;PID=1:jdoe1@example.com
  EMAIL;PID=2:jdoe2@example.com
  EMAIL;PID=3:jdoe4@example.com
  END:VCARD

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] (Crocker, D. and P. Overell, “Augmented BNF for Syntax Specifications: ABNF,” January 2008.), but it references just this small subset of [RFC5234] (Crocker, D. and P. Overell, “Augmented BNF for Syntax Specifications: ABNF,” January 2008.) literals:

 TOC 

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.



 TOC 

12.1.1.  Registration Procedure

The IETF will create a mailing list, vcard@ietf.org, 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 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 and iana@iana.org. 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.



 TOC 

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 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.



 TOC 

12.1.3.  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.
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.
Example(s):
One or more examples of instances of the property needs to be specified.



 TOC 

12.1.4.  Registration Template for Parameters

A parameter is defined by completing the following template.

Parameter name:
The name of the parameter.
Purpose:
The purpose of the parameter. Give a short but clear description.
Description:
Any special notes about the parameter, how it is to be used, etc.
Format definition:
The ABNF for the parameter definition needs to be specified.
Example(s):
One or more examples of instances of the parameter needs to be specified.



 TOC 

12.1.5.  Registration Template for Value Data Types

A value data type is defined by completing the following template.

Value name:
The name of the value type.
Purpose:
The purpose of the value type. Give a short but clear description.
Description:
Any special notes about the value type, how it is to be used, etc.
Format definition:
The ABNF for the value type definition needs to be specified.
Example(s):
One or more examples of instances of the value type needs to be specified.



 TOC 

12.1.6.  Registration Template for Values

A value is defined by completing the following template.

Value:
The value literal.
Purpose:
The purpose of the value. Give a short but clear description.
Conformance:
The vCard properties and/or parameters that can take this value needs to be specified.
Example(s):
One or more examples of instances of the value needs to be specified.

The following is a fictitious example of a registration of a vCard value:

Value:
TOP-SECRET
Purpose:
This value is used to specify the access classification of top-secret vCards.
Conformance:
This value can be used with the "CLASS" property.
Example(s):
The following is an example of this value used with the "CLASS" property:

  CLASS:TOP-SECRET
