Such interchanges frequently include the exchange of informal information, such as business cards, telephone numbers, addresses, dates and times of appointments, etc. Augmenting PDI with electronics and telecommunications can help ensure that information is quickly and reliably communicated, stored, organized and easily located when needed. Personal information, by nature, is complex and diverse. Currently, proprietary standards exist to structure some types of PDI information, but no single, open specification comprehensively addresses the needs of collecting and communicating PDI information across many common communication channels such as telephones, voice-mail, e-mail, and face-to-face meetings. versit is developing a comprehensive family of PDI technologies based on open specifications and interoperability agreements to help meet this technology need. Overview This specification defines a format for an electronic business card, or vCard. The format is suitable as an interchange format between applications or systems. The format is defined independent of the particular method used to transport it. The transport for this exchange might be a file system, point-to-point asynchronous communication, wired-network transport, or some form of unwired transport. A vCard is a data stream consisting of one or more vCard objects. The individual vCard definitions can be identified and parsed within the datastream. The vCard data stream may exist as a persistent form in a file system, document management system, network connection between two network endpoints, or in any other digital transport that has an abstraction of a stream of bytes. Conceptually, a vCard Writer creates vCard data streams and a vCard Reader interprets vCard data streams. The vCard Reader and Writer may be implemented as a single application or as separate applications. It is not the intent of this specification to define the implementation of these processes beyond some fundamental capabilities related to the format of the vCard data stream and a common set of conformance requirements . This specification provides for a clear-text encoding that is intended to be based on the syntax used by the MIME specification (RFC 1521). The encoding of this specification can be used in environments which are constrained to 7-bit transfer encodings, short line lengths, and low bandwidth. In addition, the encoding is simple in order to facilitate the implementation of reader and writer applications on small platforms, such as Personal Digital Assistants (PDA), cellular telephones, or alphanumeric pagers. Scope The vCard is intended to be used for exchanging information about people and resources. In today's business environment, this information is typically exchanged on business cards. It is appropriate, then that this specification define this information in terms of a paradigm based on an electronic business card object. The ultimate destination for this information is often a collection of business cards, Rolodex® file, or electronic contact manager. Prior to the introduction of the vCard specification, users of such applications typically had to re-key the original information, often transcribing it from paper business cards. With the advent of the vCard specification, this information can be exchanged in an automated fashion. The basis for the data types supported by this specification have their origin in openly defined, international standards and in additional capabilities based on enhancements suggested by the demonstration of the exchange of prototypical vCards using the Internet based World-Wide-Web, Infra-red data transport, and simultaneous voice and data (SVD) modems. The "person" object defined by the CCITT X.500 Series Recommendation for Directory Services was the primary reference for the properties that are defined by this specification. Every attempt was made to make it possible to map the X.520/X.521 attributes and objects into and out of an instance of a vCard. The vCard specification has extended the capabilities that have been defined within the CCITT X.500 Series Recommendation to allow the exchange of additional information often recorded on business cards and electronic contact managers. For example, this specification provides support for exchanging graphic images representing company logos, photographs of individuals, geo-positioning information, and other extensions to properties defined by the X.500 Recommendation. The specification of all date and time values are defined in terms of the ISO 8601 standard for representation of dates and times. ISO 8601 supersedes all other international standards defined at the time this specification was drafted. The paradigm of an electronic business card is related to the concepts of an entry in a LAN/WAN directory or an electronic mail address book or distribution list. However, the requirements of the electronic business card go beyond the definitions of a "person" object found in either the CCITT X.500 Series Recommendation, network directory services, or electronic mail address book products. The vCard specification is needed to address the requirements for an interchange format for the "person" personal data type or object. Personal data applications such as Personal Information Managers (PIM) often provide an import/export capability using Comma Separated Value (CSV) or Tab Delimited Files (TDF) formats. However, these solutions do not preserve the intent of the originating application. When a CSV and TDF format is used by a PIM, the meta-data or semantics of the originating object are only apparent to a similar version of the originating application. Exchange of data between such applications is another important application of an industry-standard specification for an electronic business card interchange format, such as the vCard specification. Contents This specification is separated into eight sections: * "Section 1 : Introduction" introduces PDI and the vCard specification with an overview, scope statement and section on definitions and abbreviations. * "Section 2 : vCard Specification" defines the semantics and syntax for the vCard. * "Section 3 : Internet Recommendations" specifies a set of guidelines to facilitate the exchange of vCard objects over Internet protocols such as HTTP using HTML and SMTP using MIME. * "Section 4 : UI Support Recommendations" specifies a set of guidelines to facilitate the exchange of vCard objects at the desktop user interface using the file system, clipboard and drag/drop capabilities of the operating system. * "Section 5 : Conformance" defines minimum conformance requirements to consider while developing support for this vCard specification. Definitions and Abbreviations Definitions and abbreviations used within this specification follow. Electronic Business Card: Also known as vCard. FPI: Formal Public Identifier. A string expression that represents a public identifier for an object. FPI syntax is defined by ISO 9070. GUID: Globally Unique IDentifier Internet: A WAN connecting thousands of disparate networks in industry, education, government, and research. The Internet uses TCP/IP as the standard for transmitting information. ISO: Organization for International Standardization; a worldwide federation of national standards bodies (ISO Member bodies). MIME: Multipurpose Internet Mail Extensions, as defined in RFC1521. PDA: Personal Digital Assistant computing device PDI: Personal Data Interchange, a collaborative application area which involves the communication of data between people who have a business or personal relationship, but do not necessarily share a common computing infrastructure. PIM: Personal Information Manager RFC#### documents: Internet "Request For Comment" documents (i.e., RFC822, RFC1521, etc.). URL: Uniform Resource Locator; a string expression that can represent any resource on the Internet or local system. RFC 1738 defines the syntax for an URL. UTC: Universal Time Coordinated; also known as UCT, for Universal Coordinated Time. vCard: The generic term for an electronic, virtual information card that can be transferred between computers, PDAs, or other electronic devices through telephone lines, or e-mail networks, or infrared links. How, when, why, and where vCard are used depends on the applications developed utilizing a vCard. versitcard: a vCard. WAN: Wide-Area Network Section 2 : vCard Specificiation [DS3] This section defines the semantics and syntax for the vCard. A vCard is a collection of one or more properties. A property is a uniquely named value. A set of properties can be grouped within a vCard. For example, the properties for a telephone number and comment can be grouped in order to preserve the coupling of the annotation with the telephone number. In addition to property groupings, a vC. versit is developing a comprehensive family of PDI technologies based on open specifications and interoperability agreements to help meet this technology need.

ISO 8601 supersedes all other international standards defined at the time this specification was drafted. The paradigm of an electronic business card is related to the concepts of aQuoted-Printable lines of text must also be limited to less than 76 characters. The 76 characters does not include the CRLF (RFC 822) line break sequence. For example a multiple line LABEL property value of: 123 Winding Way Any Town, CA 12345 USA Would be represented in a Quoted-Printable encoding as: LABEL;ENCODING=QUOTED-PRINTABLE:123 Winding Way=0D=0A= Any Town, CA 12345=0D=0A= USA Property parameter substrings are delimited by a field delimiter, specified by the Semi-colon character (ASCII decimal 59). A Semi-colon in a property parameter value must be escaped with a Backslash character (ASCII 92). Compound property values are property values that also make use of the Semi-colon, field delimiter to separate positional components of the value. For example, the Name property is made up of the Family Name, Given Name, etc. components. A Semi-colon in a component of a compound property value must be escaped with a Backslash character (ASCII 92). Grouping There are two forms of grouping or collections supported within the vCard. A collection of vCard objects can be grouped and a collection of properties within an individual vCard can be grouped. vCard Grouping The vCard data stream can consist of multiple vCard objects. The vCard data stream can, sequentially, contain one or more vCard objects., In addition, the vCard data stream can contain a property whose value is a nested vCard. In both of these cases, each vCard object will be delimited by the vCard Delimiters. The vCard Reader conforming to this specification must be able to parse and process any of these combinations of vCard Groupings. The support for vCard Grouping is optional for a vCard Writer conforming to this specification. Property Grouping A Property Grouping is the definition of a method for specifying a collection of related properties within a vCard object. There is no requirement on a vCard reader that it preserve the property group name. However, the vCard reader is required to preserve the grouping of the properties. The Property Grouping is identified by a character string prefix to the property name; separated by the Period character (ASCII decimal 46). The grouping of a comment property with a telephone property is shown in the following example: A.TEL;HOME:+1-213-555-1234 A.NOTE:This is my vacation home. The vCard Reader conforming to this specification must be able to parse and process the property grouping. The support for Property Grouping is optional for a vCard Writer conforming to this specification. Encodings The default encoding for the vCard object is 7-Bit. The default encoding can be overridden for an individual property value by using the "ENCODING" property parameter. This parameter value can be either "BASE64", "QUOTED-PRINTABLE", or "8BIT". This parameter may be used on any property. Some transports (e.g., MIME based electronic mail) may also provide an encoding property at the transport wrapper level. This property can be used in these cases for transporting a vCard data stream that has been defined using a default encoding other than 7-bit (e.g., 8-bit). Character Set The default character set is ASCII. The default character set can be overridden for an individual property value by using the "CHARSET" property parameter. This property parameter may be used on any property. However, the use of this parameter on some properties may not make sense. Any character set registered with the Internet Assigned Numbers Authority (IANA) can be specified by this property parameter. For example, ISO 8859-8 or the Latin/Hebrew character set is specified by: ADR;CHARSET=ISO-8859-8:... Some transports (e.g., MIME based electronic mail) may also provide a character set property at the transport wrapper level. This property can be used in these cases for transporting a vCard data stream that has been defined using a default character set other than ASCII (e.g., UTF-8). Language The default language is "en-US" (US English). The default language can be overridden for an individual property value by using the "LANGUAGE" property parameter. The values for this property are a string consistent with RFC 1766, Tags for the Identification of Languages. This property parameter may be used on any property. However, the use of this parameter on some properties, such as PHOTO, LOGO, SOUND, TEL, may not make sense. Canadian French would be specified by this parameter by the following: ADR;LANGUAGE=fr-CA:... Value Location The default location of the property value is inline with the property. However, for some properties, such as those that specify multimedia values, it is efficient to organize the property value as a separate entity (e.g., a file out on the network). The property parameter "VALUE" can be specified to override the "INLINE" location of the property value. In the case of the vCard being transported within a MIME email message, the property value can be specified as being located in a separate MIME entity with the "Content-ID" value, or "CID" for short. In this case, the property value is the Content-ID for the MIME entity containing the property value. In addition, the property value can be specified as being located out on the network within some Internet resource with the "URL" value. In this case, the property value is the Uniform Resource Locator for the Internet resource containing the property value. This property parameter may be used on any property. However, the use of this parameter on some properties may not make sense; for example the Version, Time Zone, Comment, Unique Identifier, properties . The following specifies a value not located inline with the vCard but out in the Internet: PHOTO;VALUE=URL;TYPE=GIF:http://www.abc.com/dir_photos/my_photo.gif SOUND;VALUE=CONTENT-ID:<jsmith.part3.960817T083000.xyzMail@host1.com Binary Values The vCard format supports inclusion of binary information, such as computer graphic images, digital audio, or video graphic images. The binary information may either be referenced with a Uniform Reference Locator (URL) or placed inline in the vCard as the value of a property. Inline binary information is included as a property value after being encoded into clear-text with a Base 64 (default) or Quoted-Printable encoding Identification Properties These property types are concerned with information associated with the identification and naming of the individual or resource associated with the vCard object. Formatted Name This property specifies the formatted name string associated with the vCard object. This is the way that the name is to be displayed. It can contain desired honorific prefixes, suffixes, titles, etc. For example, "Mr. John Q. Public, Jr.", Dr. Ann Tyler, or Hon. Judge Blackwell. This property is based on the semantics of the X.520 Common Name attribute. This property is identified by the property name FN. The following is an example of the Formatted Name property: FN:Mr. John Q. Public, Esq. Support for this property is optional for vCard Writers conforming to this specification. Name This property specifies a structured representation of the name of the person, place or thing associated with the vCard object. This property is identified by the property name N. This property is defined to encapsulate the individual components of an object's name. The property value consists of the components of the name specified as positional fields separated by the Field Delimiter character (ASCII decimal 59). The property value is a concatenation of the Family Name (first field), Given Name (second field), Additional Names (third field), Name Prefix (fourth field), and Name Suffix (fifth field) strings. The following is an example of the Name property for a person: N:Public;John;Quinlan;Mr.;Esq. The following is an example of the Name property for a resource or place: N:Veni, Vidi, Vici;The Restaurant. Support for this property is mandatory for vCard Writers conforming to this specification. All vCard data streams should include this property to facilitate a common property for collating and sorting of vCard objects. Photograph This property specifies an image or photograph of the individual associated with the vCard. The property is identified by the property name PHOTO. For example, the following syntax is an example of a referenced image file: PHOTO;VALUE=URL:file:///jqpublic.gif The following example is the syntax for including an inline GIF image file, using the Base 64 encoding: PHOTO;ENCODING=BASE64;TYPE=GIF: R0lGODdhfgA4AOYAAAAAAK+vr62trVIxa6WlpZ+fnzEpCEpzlAha/0Kc74+PjyGM SuecKRhrtX9/fzExORBSjCEYCGtra2NjYyF7nDGE50JrhAg51qWtOTl7vee1MWu1 50o5e3PO/3sxcwAx/4R7GBgQOcDAwFoAQt61hJyMGHuUSpRKIf8A/wAY54yMjHtz ... Support for this property is optional for vCard Writers conforming to this specification. Photo Format Type This property parameter is provided to specify the graphics format for the Photo property value. The property parameter includes the following values: Description Property Parameter Value TYPE= Indicates Graphics Interchange Format GIF Indicates ISO Computer Graphics Metafile CGM Indicates MS Windows Metafile WMF Indicates MS Windows Bitmap BMP Indicates IBM PM Metafile MET Indicates IBM PM Bitmap PMB Indicates MS Windows DIB DIB Indicates an Apple Picture format PICT Indicates a Tagged Image File Format TIFF Indicates Adobe PostScript format PS Indicates Adobe Page Description Format PDF Indicates ISO JPEG format JPEG Indicates ISO MPEG format MPEG Indicates ISO MPEG version 2 format MPEG2 Indicates Intel AVI format AVI Indicates Apple QuickTime format QTIME Birthdate This property specifies the date of birth of the individual associated with the vCard. The value for this property is a calendar date in a complete representation consistent with ISO 8601. This property is identified by the property name BDAY. The property value is a string conforming to the ISO 8601 calendar date, complete representation, in either basic or extended format. The following example is in the basic format of ISO 8601: BDAY:19950415 The following example is in the extended format of ISO 8601: BDAY:1995-04-15 Support for this property is optional for vCard Writers conforming to this specification. Delivery Addressing Properties Delivery Address This property specifies a structured representation of the physical delivery address for the vCard object. The property is made up of components that are based on the X.500 Post Office Box attribute, the X.520 Street Address geographical attribute, the X.520 Locality Name geographical attribute, the X.520 State or Province Name geographical attribute, the X.520 Postal Code attribute, and the X.520 Country Name geographical attribute. This property is identified by the property name ADR. The property value consists of components of the address specified as positional fields separated by the Field Delimiter character (ASCII decimal 59). The property value is a concatenation of the Post Office Address (first field) Extended Address (second field), Street (third field), Locality (fourth field), Region (fifth field), Postal Code (six field), and Country (seventh field) strings. An example of this property follows: ADR;DOM;HOME:P.O. Box 101;Suite 101;123 Main Street;Any Town;CA;91921-1234; Support for this property is optional for vCard Writers conforming to this specification. Delivery Address Type This property parameter specifies the sub-types of physical delivery that is associated with the delivery address. For example, the label may need to be differentiated for Home, Work, Parcel, Postal, Domestic, and International physical delivery. One or more sub-types can be specified for a given delivery address. The property parameter can have one or more of the following values: Description Property Parameter Value TYPE= Indicates a domestic address DOM Indicates an international address (Default) INTL Indicates a postal delivery address (Default) POSTAL Indicates a parcel delivery address (Default) PARCEL Indicates a home delivery address HOME Indicates a work delivery address (Default) WORK The default property parameter is overridden to some other set of values by specifying one or more alternate values. For example, the default of a delivery for INTL, WORK, POSTAL and PARCEL can be reset to DOM, POSTAL, WORK and HOME in the following example: ADR;DOM;WORK;HOME;POSTAL:P.O. Box 101;;;Any Town;CA;91921-1234; Delivery Label This property specifies the addressing label for physical delivery to the person/object associated with the vCard. The property is intended to include the information necessary to create a formatted delivery address label. Typical information includes the name, street address, possibly a Post Office or mail drop, city, state or province, zip or postal code. An international delivery label would also include the country name. This property is based on the semantics of the X.520 Postal Address attribute. This specification has added semantics to those defined by the X.500 Series standard for differentiating Home, Work, Parcel, Postal, Domestic, and International delivery label types. This property is identified by the property name LABEL. This property specifies the formatted delivery address label for the vCard object. An example of a domestic delivery label follows: LABEL;DOM;POSTAL;ENCODING=QUOTED-PRINTABLE:P. O. Box 456=0D=0A= 123 Main Street=0D=0A= Any Town, CA 91921-1234 An example of an international delivery label follows: LABEL;INTL;PARCEL,ENCODING=QUOTED-PRINTABLE:Suite 101=0D=0A= 123 Main Street=0D=0A= Any Town, CA 91921-1234=0D=0A= U.S.A. Support for this property is optional for vCard Writers conforming to this specification. A vCard Reader supporting this property and conforming to this specification should support a minimum of four lines of text for this property. Delivery Label Type This property parameter specifies the sub-types of physical delivery that is associated with the delivery label. For example, the label may need to be differentiated for Home, Work, Parcel, Postal, Domestic, and International physical delivery. One or more sub-types can be specified for a given delivery label. The property parameter can have one or more of the following values: Description Property Parameter Value TYPE= Indicates a domestic address DOM Indicates an international address (Default) INTL Indicates a postal delivery address (Default) POSTAL Indicates a parcel delivery address (Default) PARCEL Indicates a home delivery address HOME Indicates a work delivery address (Default) WORK The default property parameter is overridden to some other set of values by specifying one or more alternate values. For example, the default of a delivery for INTL, WORK, POSTAL and PARCEL can be reset to DOM and HOME in the following example: LABEL;DOM;HOME,ENCODING=QUOTED-PRINTABLE:Suite 101=0D=0A= 123 Main Street=0D=0A= Any Town, CA 91921-1234 Telecommunications Addressing Properties These property types are concerned with information associated with the telecommunications addressing of the vCard object. Telephone Number This property specifies the canonical number string for a telephone number for telephony communication with the vCard object. The value of this property is specified in a canonical form in order to specify an unambiguous representation of the globally unique telephony endpoint. This property is based on the X.520 Telephone Number attribute. The canonical form cannot be dialed without first being transformed by a dialing algorithm. The dialing algorithm combines the canonical number string with knowledge of the local dialing procedures, in effect at the time of call placement to produce actual dialing instructions. The actual dialing algorithm is outside the scope of this specification. Two important canonical forms allowed by this specification are: * Apple Computer's Representation of a Canonical Static DeviceID in The Telephony Suite, version 1.0, * Microsoft TAPI in the Microsoft Windows 3.1 Telephony Programmer's Guide, version 1.0. Software which creates this property can store a string in these allowed formats. Dialing software should be prepared to parse numbers from either of the supported formats; as neither format is considered to be technically costly to support. This property is identified by the property name TEL. An example of this property follows: TEL;PREF;WORK;MSG;FAX:+1-800-555-1234 Support for this property is optional for vCard Writers conforming to this specification. Telephone Type This property parameter specifies the sub-type of telephone that is associated with the telephone number (e.g., Home, Work, Cellular, Facsimile, Video, Modem, Message Service, or Preferred). One or more sub-type values can be specified for a given telephone number. The property parameter can have one or more of the following values: Description Property Parameter Value TYPE= Indicates preferred number PREF Indicates a work number WORK Indicates a home number HOME Indicates a voice number (Default) VOICE Indicates a facsimile number FAX Indicates a messaging service on the number MSG Indicates a cellular number CELL Indicates a pager number PAGER Indicates a bulletin board service number BBS Indicates a MODEM number MODEM Indicates a car-phone number CAR Indicates an ISDN number ISDN Indicates a video-phone number VIDEO The default property parameter is overridden to some other set of values by specifying one or more alternate values. For example, the default of a VOICE telephone number can be reset to a WORK and HOME, VOICE and FAX telephone number in the following example: TEL;WORK;HOME;VOICE;FAX:+1-800-555-1234 Electronic Mail This property specifies the address for electronic mail communication with the vCard object. The address is in the form of a specific addressing type. For example, the Internet mail address for John Public might be "John.Public@abc.com" or the CompuServe Information Service address might be "71234,5678".This property is identified by the property name EMAIL. An example of this property follows: EMAIL;INTERNET:john.public@abc.com Support for this property is optional for vCard Writers conforming to this specification.

This information may provide assistance to a correspondent regarding the type of data representation which can be used, and how they may be packaged. This property parameter is based on currently accepted practices within the Internet MIME community with the "X-Mailer" header field. This property is identified by the property name MAILER. Support for this property is optional for vCard Writers conforming to this specification. An example of this property follows: MAILER:ccMail 2.2 Geographical Properties These property types are concerned with geographical positions or region information associated with the vCard object. Time Zone This property specifies information related to the standard time zone of the vCard object. The time zone is a string as specified in a manner consistent with ISO 8601. It is an offset from Coordinated Universal Time (UTC). An ISO 8601 UTC offset, in basic format, is specified as a positive or negative difference in units of hours and minutes (e.g., +hhmm). If minutes are zero, then they may be omitted and the format would be specified in units of hours (e.g., +hh). The time is specified as a 24-hour clock. Hour valult property parameter is overridden to some other set of values by specifying one or more alternate values. For example, the default of a delivery for INTL, WORK, POSTAL and PARCEL can be reset to DOM, POSTAL, WORK and HOME in the following example: ADR;DOM;WORK;HOME;POSTAL:P.O. Box 101;;;Any Town;CA;91921-1234; Delivery Label This property specifies the addressing label for physical delivery to the person/object associated with the vCard. The property is intended to include the information necessary to create a formatted delivery address label. Typical information includes the name, street address, possibly a Post Office or mail drop, city, state or province, zip or postal code. An international delivery label would also include the country name. This property is based on the semantics of the X.520 Postal Address attribute. This specification has added semantics to those defined by the X.500 Series standard for differentiating Home, Work, Parcel, Postal, Domestic, and International delivery label types. This property is identified by the property name LABEL. This property specifies the formatted delivery address label for the vCard object. An example of a domestic delivery label follows: LABEL;DOM;POSTAL;ENCODING=QUOTED-PRINTABLE:P. O.

Software which creates this property can store a string in these allowed formats. Dialing s Description Property Parameter Value TYPE= Indicates Graphics Interchange Format GIF Indicates ISO Computer Graphics Metafile CGM Indicates MS Windows Metafile WMF Indicates MS Windows Bitmap BMP Indicates IBM PM Metafile MET Indicates IBM PM Bitmap PMB Indicates MS Windows DIB DIB Indicates an Apple Picture format PICT Indicates Tagged Image File Format TIFF Indicates Adobe Page Description Format PDF Indicates Adobe PostScript PS Indicates ISO JPEG format JPEG Indicates ISO MPEG format MPEG Indicates ISO MPEG version 2 format MPEG2 Indicates Intel AVI format AVI Indicates Apple QuickTime format QTIME Agent This property specifies information about another person who will act on behalf of the vCard object. Typically this would be an area administrator, assistant, or secretary for the individual. A key characteristic of the Agent property is that it represents somebody or something which is separately addressable. For example, if all phone calls or e-mail messages are normally screened by an agent, this property may not be needed. On the other hand, if an agent can act as a proxy, and may otherwise need to be contacted separately, then an Agent property is useful. This property is equivalent to nesting another vCard with the specified vCard. This property is identified by the property name AGENT. The value of this property is a string containing another vCard object. An example of this property follows: AGENT: BEGIN:VCARD VERSION:2.1 N:Friday;Fred TEL;WORK;VOICE:+1-213-555-1234 TEL;WORK;FAX:+1-213-555-5678 END:VCARD Support for this property is optional for vCard Writers conforming to this specification. Organization Name and Organizational Unit This property specifies the name and optionally the unit(s) of the organization associated with the vCard object. This property is based on the X.520 Organization Name attribute and the X.520 Organization Unit attribute. For example, "The AB Corporation" and the "North American Division". This property is identified by the property name ORG. This property is defined to encapsulate the Organization Name and Organization Unit properties as sub-properties. The property value consists of the components of the organization specified as positional fields separated by the Field Delimiter (ASCII decimal 59). The property value is a concatenation of the Organization Name (first field), Organizational Unit (second field) strings. Additional positional fields, if specified, contain additional Organizational Units. The following is an example of the Organization property: ORG:ABC, Inc.;North American Division;Marketing Support for this property is optional for vCard Writers conforming to this specification. Explanatory Properties These property types are concerned with additional explanations, such as that related to national language support, annotation, or encoding of binary information about the vCard object. Comment This property specifies supplemental information or a comment that is associated with the vCard. With the use of property grouping, the association can be limited to a group of properties. The property is based on the X.520 Description attribute. This property is identified by the property name NOTE. An example of this property follows: NOTE;ENCODING=QUOTED-PRINTABLE:This facsimile machine if operational= 0830 to 1715 hours=0D=0A= Monday through Friday. Call +1-213-555-1234 if you have problems=0D=0A= with access to the machine. Support for this property is optional for vCard Writers conforming to this specification. Last Revision This property specifies the combination of the calendar date and time of day of the last update to the vCard object. The property value is a character string conforming to the basic or extended format of ISO 8601. The value can either be in terms of local time or UTC. This property is identified by the property name REV. Valid values for this property are a character string representing a combination of the calendar date and time of day conforming to the basic or extended format of ISO 8601. The time of day can be either local time or UTC. The following example is in the basic format and local time of ISO 8601: REV:19951031T222710 The following example is in the extended format and UTC time of ISO 8601: REV:1995-10-31T22:27:10Z Support for this property is optional for vCard Writers conforming to this specification. Sound This property specifies a sound annotation for the vCard object. By default, if this property is not grouped with other properties it specifies the pronunciation of the Formatted Name property of the vCard object. Such information may be in the form of a string of characters representing a phonetic sound or in the form of a digitized sound, or both; subject to the limitations imposed by the encoding used to communicate the vCard. This property is identified by the property name SOUND. Valid values for this property are either a string representation, a reference to a digital audio representation, or an inline digital audio representation of the phonetic pronunciation of the Formatted Name property. The following example shows the string based phonetic representation: SOUND:JON Q PUBLIK The following example shows the digtial sound representation and URL based value: SOUND;VALUE=URL:file///multimed/audio/jqpublic.wav The following example shows the digtial sound representation and INLINE value: SOUND;WAVE;BASE64: UklGRhAsAABXQVZFZm10IBAAAAABAAEAESsAABErAAABAAgAZGF0YesrAACAg4eC eXR4e3uAhoiIiYmKjIiDfnx5eX6CgoKEhYWDenV5fH6BhISGiIiDfHZ2eXt/hIiK jY2IhH12d3Vyc3uDiIiFf3l7fn18eXl+houFf319fnyAgHl5eoCIiISChIeAfnt2 ... Support for this property is optional for vCard Writers conforming to this specification. Sound Digital Audio Type This property parameteris provided to specify the type of the digital audio Pronunciation for the vCard object. The property parameter can have the following values: Description Property Parameter Value TYPE= Indicates Wave format WAVE Indicates MIME basic audio type PCM Indicates AIFF format AIFF Uniform Resource Locator This property specifies a value that represents a Uniform Resource Locator (URL). An URL is a representation of an Internet location that can be used to obtain real-time information about the vCard object. Application of this property might be to specify the location of a publicly accessible directory where up-to-date or additional information on the individual or resource associated with a vCard can be found. This property is identified by the property name URL. Valid values for this property are a string conforming to the IETF RFC 1738, Uniform Resource Locators. The following is an example of this property: URL:http://abc.com/pub/directory/northam/jpublic.ecd Support for this property is optional for vCard Writers conforming to this specification. Unique Identifier This property specifies a value that represents a persistent, globally unique identifier associated with the object. The property can be used as a mechanism to relate different vCard objects. Some examples of valid forms of unique identifiers would include ISO 9070 formal public identifiers (FPI), X.500 distinguished names, machine-generated "random" numbers with a statistically high likelihood of being globally unique and Uniform Resource Locators (URL). If an URL is specified, it is suggested that the URL reference a service which will produce an updated version of the vCard. This property is identified by the property name UID. This property is provided to enable a vCard Reader and Writer to uniquely identify either a vCard object instance or properties within a vCard object. Valid values for this property are a unique character string. The following is an example of this property: UID:19950401-080045-40000F192713-0052 Support for this property is optional for vCard Writers conforming to this specification. Version This property specifies the identifier corresponding to the highest version number of the vCard Specification supported by the implementation that created the vCard object. The value of this property must be 2.1 to correspond to this specification.. This property is identified by the property name VERSION. The following is an example of this property: VERSION:2.1 Support for this property is mandatory for implementations conforming to this specification. This property must appear within the vCard data stream. Security Properties These property types are concerned with the security of the information in the vCard object. Public Key This property specifies the public encryption key associated with the vCard object. This property is identified by the property name KEY. Valid values for this property are a public key that conforms to a bilaterally agreed to representation. If the representation is a binary format, then the public key must be further encoded. The default format is clear-text. If a binary format is used, then it is specified by the property parameter. Support for this property is optional for vCard Writers conforming to this specification. Key Type This property parameter is provided to specify the type of the public key for the vCard object. The property parameter can have the following values: Description Property Parameter Value TYPE= Indicates a X.509 public key certificate type of key X509 Indicates an IETF PGP type of key PGP Miscellaneous Properties Extensions The vCard provides a ìstandard mechanism for doing non-standard thingsî. This extension support is provided for implementers to "push the envelope" on the existing version of the specification. Extension properties are specified by property and/or property parameter names that have the initial sub-string of X- (the two character sequence: Capital X character followed by the Dash character. It is recommended that vendors concatenate onto this sentinel an added short sub-string to identify the vendor. This will facilitate readability of the extensions and minimize possible collision of names between different vendors. For example, the following might be the ABC vendor's extension for a video-clip form of identification property: X-ABC-VIDEO;MPEG2:http://lonestar.bubbas.org/billibob.mpg or, the following example might be an extension for grouping vCard objects into a distribution list for the Design Work Group. BEGIN:VCARD VERSION:2.1 X-DL;Design Work Group:List Item 1;List Item 2;List Item 3 BEGIN:VCARD UID:List Item 1 N:John Smith TEL:+1-213-555-1111 END:VCARD BEGIN:VCARD UID:List Item 2 N:I. M. Big TEL:+1-213-555-9999 END:VCARD BEGIN:VCARD UID:List Item 3 N:Jane Doe TEL:+1-213-555-5555 END:VCARD END:VCARD At present, there is no registration authority for names of extension properties. Support for this property is mandatory for implementations conforming to this specification. However, an implementation may not be able to act on the extension property. Conformance only requires that an implementation be able to parse vCard data streams with extensions. The implementation need not act on them. Formal Definition The following modified Backus-Naur Notation (BNF) is provided to assist developers in building parsers for the vCard. This syntax is written according to the form described in RFC 822, but it references just this small subset of RFC 822 literals: CR = <ASCII CR, carriage return> ; ( 15, 13.) LF = <ASCII LF, linefeed> ; ( 12, 10.) CRLF = CR LF SPACE = <ASCII SP, space> ; ( 40, 32.) HTAB = <ASCII HT, horizontal-tab> ; ( 11, 9.)

Interoperability of vCard information over SMTP/MIME transports can be better assured by following a common set of recommended practices for encapsulation of the vCard. Text/Plain Content Type Without any change to existing SMTP or MIME compliant user agents, a vCard can be included within Internet email messages. This might be the case for an existing, simple user agent such as a legacy SMTP mail system. While this approach provides for transport of vCards over SMTP services, it does not allow for the end user to take advantage of the full capabilities of either the vCard or Internet email (i.e., MIME) functionality. The following demonstrates how a vCard can be included as an epilog to a SMTP message made up of a RFC 822 message. This may be an initial method for incorporating vCard objects into SMTP messages.

The current draft name is draft-ietf-asid-mime-direct-01.txt. This specification is intended to be aligned with this work. Internet Drafts are working documents of an IETF working group, valid for at most six months, and should be considered "works in progress". This MIME content type was designed to be used to transport directory information across MIME based electronic mail services. The internet draft is directly applicable to the exchange of business card data, such as that defined by the vCard specification. The versit PDI Team has worked within the IETF ASID Working Group to draft an application/directory profile that registers the method for transporting a vCard as an application/directory Content-Type. The current draft name is draft-ietf-asid-mime-vcard-00.txt. This work is expected to be progressed to a Request For Comment after the publication of this version of the vCard specification. In the interim, the following guidelines are provided to describe how a vCard might be conveyed using the application/directory draft specification. A vCard should be included in a MIME message that has a Content-Type header field value of "multipart/related". The vCard is included in the message as the primary body part. The position of the body part entity can also be specified with the "start=" parameter. This MIME body part entity has a Content-Type body part header field value of "application/directory" with a "profile" parameter value of "vcard". Any vCard binary information, such as a logo, picture, or digital audio pronunciation can be included inline within the vCard, as is specified by the vCard specification. Preferably, the binary information should be extracted from the vCard object and contained in the MIME message as secondary body part entities. The binary content in the secondary body part entities can be referenced from within the vCard object through the use of the "VALUE=" property parameter. In this latter case, the binary information should be transformed into a content type nominally supported by MIME user agents. For image content, this would be the Graphics Image Format (GIF) or Joint Picture Encoding Group (JPEG) formats. For audio content, this would be the 8-bit mu-law (PCM) format specified by the MIME specification. The following example defines how this might be specified: Date: Mon, 29 Jan 96 0830 EDT From: john.smith@host.com Subject: Re: MIME application/directory vCard Example Sender: john.smith@host.com To: smartin@host2.com Message-ID: <JOHNSMITH.960129T083020.xyzMail@host3.com> Content-Type: multipart/related; boundary="vcard"; type=application/directory; start=<JOHNSMITH.part1.960129T083020.xyzMail@host3.com> --vcard Content-Type: application/directory; charset=us-ascii; source="file://versit.or2"; profile="vcard" Content-ID: <<JOHNSMITH.part1.960129T083020.xyzMail@host3.com> BEGIN:VCARD VERSION:2.1 N:Smith;John;M.;Mr.;Esq.

The non-standard subtype should be used because the vCard has not been registered as a MIME media type with the IANA. The vCard information can be captured with a FORM type of HTML document. Interoperability of of vCard information can be better assured by following a common set of recommended practices for mapping vCard information into and out of HTML documents. Form Element Usage The HTML FORM element is a useful method for capturing data intended for input into individual vCard property values. The following recommended practices are provided for such use. Mapping To INPUT Element Attribute Names An HTML form data set is a useful mechanism for capturing vCard data within the Internet WWW. The use of a consistent naming scheme for the name attributes within a form element will permit implementations to support automatic fill-in of forms with existing vCard data. In addition, such a consistent naming scheme will provide a greater assurance of interoperability between HTML based applications that use vCard data. The following table provides a recommended mapping of vCard properties and name attributes within a form element. Identification Properties Description Attribute Name Comment Formatted Name FN Name N Individual components of name property are captured as separate input elements with the names N.Family, N.First, N.Middle, N.Prefix, N.Suffix. Photograph PHOTO Only the URL based specification is supported by this mapping. Value is the URL for the graphic. Photograph Format Type PHOTO.Type Where the value is one of the enumerated strings defined by the vCard specification. Birthdate BDAY Delivery Addressing Properties Description Attribute Name Comment Delivery Address ADR TYPE=TEXTAREA Address Type ADR.x TYPE=CHECKBOX. Separate input elements are used to capture the possible delivery types. The elements are named ADR.x, where x is one of the enumerated strings defined by the vCard specification. Delivery Label LABEL Label Type LABEL.x TYPE=CHECKBOX. Separate input elements are used to capture the possible delivery types. The elements are named LABEL.x, where x is one of the enumerated strings defined by the vCard specification. Telecommunications Addressing Properties Description Attribute Name Comment Telephone Number TEL Telephone Type TEL.x TYPE=CHECKBOX.

Agent Captured through a separate form element using the mapping defined in these tables. Organization ORG TYPE=TEXT. Separate input elements for the organizational name and unit. The name ORG.Name is used to capture the organizational name. The name ORG.UNIT is used to capture the organizational unit. If there are multiple organizational units, it is captured in a form with name attributes ORG.UNIT1, ORG.UNIT2, etc. Explanatory Properties Description Attribute Name Comment Comment NOTE TYPE=TEXT Last Revision REV A hidden field.
