Abstract This memo defines the profile of the MIME Content-Type [MIME-DIR] for directory information for a white-pages person object, based on a vCard electronic business card. The profile definition is independent of any particular directory service or protocol. The profile is defined for representing and exchanging a variety of information about an individual (e.g., formatted and structured name and delivery addresses, email address, multiple telephone numbers, photograph, logo, audio clips, etc.). The directory information used by this profile is based on the attributes for the person object defined in the X.520 and X.521 directory services recommendations. The profile also provides the method for including a [VCARD] representation of a white-pages directory entry within the MIME Content-Type defined by the [MIME-DIR] document. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY" and "OPTIONAL" in this document are to be interpreted as described in [RFC 2119].

FULL COPYRIGHT STATEMENT..........................................37 Dawson & Howes [Page 3] Expires January 1999 vCard MIME Directory Profile Overview The [MIME-DIR] document defines a MIME Content-Type for holding different kinds of directory information. The directory information can be based on any of a number of directory schemas. This document defines a [MIME-DIR] usage profile for conveying directory information based on one such schema; that of the white-pages type of person object. The schema is based on the attributes for the person object defined in the X.520 and X.521 directory services recommendations. The schema has augmented the basic attributes defined in the X.500 series recommendation in order to provide for an electronic representation of the information commonly found on a paper business card. This schema was first defined in the [VCARD] document. Hence, this [MIME- DIR] profile is referred to as the vCard MIME Directory Profile. A directory entry based on this usage profile can include traditional directory, white-pages information such as the distinguished name used to uniquely identify the entry, a formatted representation of the name used for user-interface or presentation purposes, both the structured and presentation form of the delivery address, various telephone numbers and organizational information associated with the entry. In addition, traditional paper business card information such as an image of an organizational logo or identify photograph can be included in this person object. The vCard MIME Directory Profile also provides support for representing other important information about the person associated with the directory entry. For instance, the date of birth of the person; an audio clip describing the pronunciation of the name associated with the directory entry, or some other application of the digital sound; longitude and latitude geo-positioning information related to the person associated with the directory entry; date and time that the directory information was last updated; annotations often written on a business card; Uniform Resource Locators (URL) for a website; public key information. The profile also provides support for non-standard extensions to the schema. This provides the flexibility for implementations to augment the current capabilities of the profile in a standardized way. More information about this electronic business card format can be found in [VCARD]. 1. The vCard Mime Directory Profile Registration This profile is identified by the following [MIME-DIR] registration template information. Subsequent sections define the profile definition. To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME profile VCARD Profile name: VCARD Dawson & Howes [Page 4] Expires January 1999 vCard MIME Directory Profile Profile purpose: To hold person object or white-pages type of directory information. The person schema captured in the directory entries is that commonly found in an electronic business card. Predefined MIME Directory value specifications used: uri, date, date- time, float New value specifications: This profile places further constraints on the [MIME-DIR] text value specification. In addition, it adds a binary, phone-number, utc-offset and vcard value specifications. Predefined MIME Directory types used: SOURCE, NAME, PROFILE, BEGIN, END. Predefined MIME Directory parameters used: ENCODING, VALUE, CHARSET, LANGUAGE, CONTEXT. New types: FN, N, NICKNAME, PHOTO, BDAY, ADR, LABEL, TEL, EMAIL, MAILER, TZ, GEO, TITLE, ROLE, LOGO, AGENT, ORG, CATEGORIES, NOTE, PRODID, REV, SORT-STRING, SOUND, URL, UID, VERSION, CLASS, KEY New parameters: TYPE Profile special notes: The vCard object MUST contain the FN, N and VERSION types. The type-grouping feature of [MIME-DIR] is supported by this profile to group related vCard properties about a directory entry. For example, vCard properties describing WORK or HOME related characteristics can be grouped with a unique group label. The profile permits the use of non-standard types (i.e., those identified with the prefix string "X-") as a flexible method for implementations to extend the functionality currently defined within this profile. 2. MIME Directory Features The vCard MIME Directory Profile makes use of many of the features defined by [MIME-DIR]. The following sections either clarify or extend the content-type definition of [MIME-DIR]. 2.1 Predefined Type Usage The vCard MIME Directory Profile uses the following predefined types from [MIME-DIR]. 2.1.1 BEGIN and END Type The content entity MUST begin with the BEGIN type with a value of "VCARD". The content entity MUST end with the END type with a value of "VCARD". Dawson & Howes [Page 5] Expires January 1999 vCard MIME Directory Profile 2.1.2 NAME Type If the NAME type appears within a MIME entity conforming to this profile, its value is the displayable, presentation text associated with the source for the vCard, as specified in the SOURCE type. 2.1.3 PROFILE Type If the PROFILE type appears within a MIME entity conforming to this profile, its value MUST be "VCARD". 2.1.4 SOURCE Type If the SOURCE type appears within a MIME entity conforming to this profile, its value provides information how to find the source for the vCard. 2.2 Predefined Type Parameter Usage The vCard MIME Directory Profile uses the following predefined type parameters as defined by [MIME-DIR]. - LANGUAGE - ENCODING - VALUE 2.3 Predefined VALUE Type Usage The predefined data type values specified in [MIME-DIR] MUST NOT be repeated in COMMA separated value lists, unless specified by this specification. The text value type defined in [MIME-DIR] is further restricted such that any SEMI-COLON character (ASCII decimal 59) in the value MUST be escaped with the BACKSLASH character (ASCII decimal 92). 2.4 Extensions To The Predefined VALUE Types The predefined data type values specified in [MIME-DIR] have been extended by the vCard profile to include a number of value types that are specific to this profile. 2.4.1 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 Dawson & Howes [Page 6] Expires January 1999 vCard MIME Directory Profile encoded binary data SHOULD BE folded to 75 characters using the folding method defined in [MIME-DIR]. The value type is defined by the following notation: binary = <A "B" binary encoded string as defined by [RFC 2047].> 2.4.2 VCARD The "vcard" value type specifies that the type value is another vCard. This value type can be specified in the AGENT type. The value type is defined by this specification. Since each of the type declarations with in the vcard value type are being specified within a text value themselves, they MUST be terminated with the backslash escape sequence "\n" or "\N", instead of the normal newline character sequence CRLF. In addition, any COMMA character (ASCII decimal 44), SEMI-COLON character (ASCII decimal 59) and COLON character (ASCII decimal 58) MUST be escaped with the BACKSLASH character (ASCII decimal 92). For example, with the AGENT type a value would be specified as : AGENT:BEGIN:VCARD\nFN:Joe Friday\nTEL:+1-919-555-7878\n TITLE:Area Administrator,円 Assistant\n EMAIL\;TYPE=INTERN\n ET:jfriday@host.com\nEND:VCARD\n 2.4.3 PHONE-NUMBER The "phone-number" value type specifies that the type value is a telephone number. This value type can be specified in the TEL type. The value type is a text value that has the special semantics of a telephone number as defined in [CCITT E.163] and [CCITT X.121]. 2.4.4 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. The value is defined by the following notation: time-hour = 2DIGIT ;00-23 time-minute = 2DIGIT ;00-59 utc-offset = ("+" / "-") time-hour ":" time-minute Dawson & Howes [Page 7] Expires January 1999 vCard MIME Directory Profile 2.5 Structured Type Values 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). 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). This profile supports the type grouping mechanism defined in [MIME- DIR]. Grouping of related types is a useful technique to communicate common semantics concerning the properties of a vCard. 2.6 Line Delimiting and Folding This profile supports the same line delimiting and folding methods defined in [MIME-DIR]. Specifically, when parsing a content line, folded lines must first be unfolded according to the unfolding procedure described in [MIME-DIR]. After generating a content line, lines longer than 75 characters SHOULD be folded according to the folding procedure described in [MIME DIR]. 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. 3. vCard Profile Features The vCard MIME Directory Profile Type contains directory information, typically pertaining to a single directory entry. The information is described using an attribute schema that is tailored for capturing personal contact information. The vCard can include attributes that describe identification, delivery addressing, telecommunications addressing, geographical, organizational, general explanatory and security and access information about the particular object associated with the vCard. 3.1 Identification Types These types are used in the vCard profile to capture information associated with the identification and naming of the person or resource associated with the vCard. 3.1.1 FN Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type FN Type name:FN Type purpose: To specify the formatted text corresponding to the name of the object the vCard represents. Dawson & Howes [Page 8] Expires January 1999 vCard MIME Directory Profile Type encoding: 8bit Type value: A single text value. Type special notes: This type is based on the semantics of the X.520 Common Name attribute. The property MUST be present if the vCard conforms to this specification. Type example: FN:Mr. John Q. Public,円 Esq. 3.1.2 N Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type N Type name: N Type purpose: To specify the components of the name of the object the vCard represents. Type encoding: 8bit Type value: A single structured text value. Each component can have multiple values. Type special note: The structured type 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 type is based on the semantics of the X.520 individual name attributes. The property MUST be present in the vCard object. Type example: N:Public;John;Quinlan;Mr.;Esq. N:Stevenson;John;Philip,Paul;Dr.;Jr.,M.D.,A.C.P. 3.1.3 NICKNAME Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type NICKNAME Type name: NICKNAME Type purpose: To specify the text corresponding to the nickname of the object the vCard represents. Dawson & Howes [Page 9] Expires January 1999 vCard MIME Directory Profile Type encoding: 8bit Type value: One or more text values separated by a COMMA character (ASCII decimal 44). Type 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 types. Type example: NICKNAME:Robbie NICKNAME:Jim,Jimmie 3.1.4 PHOTO Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type PHOTO Type name: PHOTO Type purpose: To specify an image or photograph information that annotates some aspect of the object the vCard represents. Type 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. Type value: 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. Type special notes: The type can include the type parameter "TYPE" to specify the graphic image format type. The TYPE parameter values MUST be one of the IANA registered image formats or a non-standard image format. Type example: PHOTO;VALUE=uri:http://www.abc.com/pub/photos /jqpublic.gif PHOTO;ENCODING=b;TYPE=JPEG:MIICajCCAdOgAwIBAgICBEUwDQYJKoZIhvcN AQEEBQAwdzELMAkGA1UEBhMCVVMxLDAqBgNVBAoTI05ldHNjYXBlIENvbW11bm ljYXRpb25zIENvcnBvcmF0aW9uMRwwGgYDVQQLExNJbmZvcm1hdGlvbiBTeXN0 <...remainder of "B" encoded binary data...> Dawson & Howes [Page 10] Expires January 1999 vCard MIME Directory Profile 3.1.5 BDAY Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type BDAY Type name: BDAY Type purpose: To specify the birth date of the object the vCard represents. Type encoding: 8bit Type value: The default is a single date value. It can also be reset to a single date-time value. Type examples: BDAY:1996年04月15日 BDAY:1953年10月15日T23:10:00Z BDAY:1987年09月27日T08:30:00-06:00 3.2 Delivery Addressing Types These types are concerned with information related to the delivery addressing or label for the vCard object. 3.2.1 ADR Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type ADR Type name: ADR Type purpose: To specify the components of the delivery address for the vCard object. Type encoding: 8bit Type value: A single structured text value, separated by the SEMI- COLON character (ASCII decimal 59). Type 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; 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. Dawson & Howes [Page 11] Expires January 1999 vCard MIME Directory Profile 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 "dom" to indicate a domestic delivery address; "intl" to indicate an international delivery address; "postal" to indicate a postal delivery address; "parcel" to indicate a parcel delivery address; "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=dom;TYPE=postal") or as a value list (i.e., "TYPE=dom,postal"). This type is based on semantics of the X.520 geographical and postal addressing attributes. The default is "TYPE=intl,postal,parcel,work". The default can be overridden to some other set of values by specifying one or more alternate values. For example, the default can be reset to "TYPE=dom,postal,work,home" to specify a domestic delivery address for postal delivery to a residence that is also used for work. Type example: In this example the post office box and the extended address are absent. ADR;TYPE=dom,home,postal,parcel:;;123 Main Street;Any Town;CA;91921-1234 3.2.2 LABEL Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type LABEL Type name: LABEL Type purpose: To specify the formatted text corresponding to delivery address of the object the vCard represents. Type encoding: 8bit Type value: A single text value. Type special notes: The type value is formatted text that can be used to present a delivery address label for the vCard object. The type can include the type parameter "TYPE" to specify delivery label type. The TYPE parameter values can include "dom" to indicate a domestic delivery label; "intl" to indicate an international delivery label; "postal" to indicate a postal delivery label; "parcel" to indicate a parcel delivery label; "home" to indicate a delivery label for a residence; "work" to indicate delivery label for a place of work; and "pref" to indicate the preferred delivery label when more than one Dawson & Howes [Page 12] Expires January 1999 vCard MIME Directory Profile label is specified. These type parameter values can be specified as a parameter list (i.e., "TYPE=dom;TYPE=postal") or as a value list (i.e., "TYPE=dom,postal"). This type is based on semantics of the X.520 geographical and postal addressing attributes. The default is "TYPE=intl,postal,parcel,work". The default can be overridden to some other set of values by specifying one or more alternate values. For example, the default can be reset to "TYPE=intl,post,parcel,home" to specify an international delivery label for both postal and parcel delivery to a residential location. Type example: A multi-line address label. LABEL;TYPE=dom,home,postal,parcel:Mr.John Q. Public,円 Esq.\n Mail Drop: TNE QB\n 123 Main Street\n Any Town,円 CA 91921-1234\n U.S.A. 3.3 Telecommunications Addressing Types These types are concerned with information associated with the telecommunications addressing of the object the vCard represents. 3.3.1 TEL Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type TEL Type name: TEL Type purpose: To specify the telephone number for telephony communication with the object the vCard represents. Type encoding: 8bit Type value: A single phone-number value. Type special notes: The value of this type is specified in a canonical form in order to specify an unambiguous representation of the globally unique telephone endpoint. This type is based on the X.500 Telephone Number attribute. The type can include the type parameter "TYPE" to specify intended use for the telephone number. The TYPE parameter values can include: "home" to indicate a telephone number associated with a residence, "msg" to indicate the telephone number has voice messaging support, "work" to indicate a telephone number associated with a place of work, "pref" to indicate a preferred-use telephone number, "voice" to indicate a voice telephone number, "fax" to indicate a facsimile telephone number, "cell" to indicate a cellular telephone number, "video" to indicate a video conferencing telephone number, "pager" to indicate a paging device telephone number, "bbs" to indicate a bulletin board system telephone number, "modem" to indicate a MODEM Dawson & Howes [Page 13] Expires January 1999 vCard MIME Directory Profile connected telephone number, "car" to indicate a car-phone telephone number, "isdn" to indicate an ISDN service telephone number, "pcs" to indicate a personal communication services telephone number. The default type is "voice". These type parameter values can be specified as a parameter list (i.e., "TYPE=work;TYPE=voice") or as a value list (i.e., "TYPE=work,voice"). The default can be overridden to another set of values by specifying one or more alternate values. For example, the default TYPE of "voice" can be reset to a WORK and HOME, VOICE and FAX telephone number by the value list "TYPE=work,home,voice,fax". Type example: TEL;TYPE=work,voice,pref,msg:+1-213-555-1234 3.3.2 EMAIL Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type EMAIL Type name: EMAIL Type purpose: To specify the electronic mail address for communication with the object the vCard represents. Type encoding: 8bit Type value: A single text value. Type special notes: The type can include the type parameter "TYPE" to specify the format or preference of the electronic mail address. The TYPE parameter values can include: "internet" to indicate an Internet addressing type, "x400" to indicate a X.400 addressing type or "pref" to indicate a preferred-use email address when more than one is specified. Another IANA registered address type can also be specified. The default email type is "internet". A non-standard value can also be specified. Type example: EMAIL;TYPE=internet:jqpublic@xyz.dom1.com EMAIL;TYPE=internet:jdoe@isp.net EMAIL;TYPE=internet,pref:jane_doe@abc.com 3.3.3 MAILER Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type MAILER Type name: MAILER Dawson & Howes [Page 14] Expires January 1999 vCard MIME Directory Profile Type purpose: To specify the type of electronic mail software that is used by the individual associated with the vCard. Type encoding: 8bit Type value: A single text value. Type special notes: This information can provide assistance to a correspondent regarding the type of data representation which can be used, and how they can be packaged. This property is based on the private MIME type X-Mailer that is generally implemented by MIME user agent products. Type example: MAILER:PigeonMail 2.1 3.4 Geographical Types These types are concerned with information associated with geographical positions or regions associated with the object the vCard represents. 3.4.1 TZ Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type TZ Type name: TZ Type purpose: To specify information related to the time zone of the object the vCard represents. Type encoding: 8bit Type value: The default is a single utc-offset value. It can also be reset to a single text value. Type 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. 3.4.2 GEO Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type GEO Dawson & Howes [Page 15] Expires January 1999 vCard MIME Directory Profile Type name: GEO Type purpose: To specify information related to the global positioning of the object the vCard represents. Type encoding: 8bit Type value: A single structured value consisting of two float values separated by the SEMI-COLON character (ASCII decimal 59). Type special notes: This type 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 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. Type example: GEO:37.386013;-122.082932 3.5 Organizational Types These types are concerned with information associated with characteristics of the organization or organizational units of the object the vCard represents. 3.5.1 TITLE Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type TITLE Type name: TITLE Type purpose: To specify the job title, functional position or function of the object the vCard represents. Type encoding: 8bit Type value: A single text value. Type special notes: This type is based on the X.520 Title attribute. Type example: Dawson & Howes [Page 16] Expires January 1999 vCard MIME Directory Profile TITLE:Director,円 Research and Development 3.5.2 ROLE Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type ROLE Type name: ROLE Type purpose: To specify information concerning the role, occupation, or business category of the object the vCard represents. Type encoding: 8bit Type value: A single text value. Type special notes: This type 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 type and incorrect usage of that type when the semantics of this type is intended. Type example: ROLE:Programmer 3.5.3 LOGO Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type LOGO Type name: LOGO Type purpose: To specify a graphic image of a logo associated with the object the vCard represents. Type 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. Type value: 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. Type special notes: The type can include the type parameter "TYPE" to specify the graphic image format type. The TYPE parameter values MUST be one of the IANA registered image formats or a non-standard image format.

Type encoding: 8-bit Type value: The default is a single vcard value. It can also be reset to either a single text or uri value. The text value can be used to specify textual information. The uri value can be used to specify information outside of this MIME entity. Type special notes: This type typically is used to specify an area administrator, assistant, or secretary for the individual associated with the vCard. A key characteristic of the Agent type is that it represents somebody or something that is separately addressable. Type example: AGENT;VALUE=uri: CID:JQPUBLIC.part3.960129T083020.xyzMail@host3.com AGENT:BEGIN:VCARD\nFN:Susan Thomas\nTEL:+1-919-555- 1234\nEMAIL\;INTERNET:sthomas@host.com\nEND:VCARD\n 3.5.5 ORG Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type ORG Type name: ORG Type purpose: To specify the organizational name and units associated with the vCard. Type encoding: 8bit Type value: A single structured text value consisting of components separated the SEMI-COLON character (ASCII decimal 59). Dawson & Howes [Page 18] Expires January 1999 vCard MIME Directory Profile Type special notes: The type is based on the X.520 Organization Name and Organization Unit attributes. The type value is a structured type consisting of the organization name, followed by one or more levels of organizational unit names. Type example: A type value consisting of an organizational name, organizational unit #1 name and organizational unit #2 name. ORG:ABC,円 Inc.;North American Division;Marketing 3.6 Explanatory Types These types are concerned with additional explanations, such as that related to informational notes or revisions specific to the vCard. 3.6.1 CATEGORIES Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type CATEGORIES Type name: CATEGORIES Type purpose: To specify application category information about the vCard. Type encoding: 8bit Type value: One or more text values separated by a COMMA character (ASCII decimal 44). Type example: CATEGORIES:TRAVEL AGENT CATEGORIES:INTERNET,IETF,INDUSTRY,INFORMATION TECHNOLOGY 3.6.2 NOTE Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type NOTE Type name: NOTE Type purpose: To specify supplemental information or a comment that is associated with the vCard. Type encoding: 8bit Type value: A single text value. Type special notes: The type is based on the X.520 Description attribute. Dawson & Howes [Page 19] Expires January 1999 vCard MIME Directory Profile Type example: NOTE:This fax number is operational 0800 to 1715 EST,円 Mon-Fri. 3.6.3 PRODID Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type PRODID Type name: PRODID Type purpose: To specify the identifier for the product that created the vCard object. Type encoding: 8-bit Type value: A single text value. Type special notes: Implementations SHOULD use a method such as that specified for Formal Public Identifiers in ISO 9070 to assure that the text value is unique. Type example: PRODID:-//ONLINE DIRECTORY//NONSGML Version 1//EN 3.6.4 REV Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type REV Type name: REV Type purpose: To specify revision information about the current vCard. Type encoding: 8-bit Type value: The default is a single date-time value. Can also be reset to a single date value. Type special notes: The value distinguishes the current revision of the information in this vCard for other renditions of the information. Type example: REV:1995年10月31日T22:27:10Z REV:1997年11月15日 Dawson & Howes [Page 20] Expires January 1999 vCard MIME Directory Profile 3.6.5 SORT-STRING Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type SORT-STRING Type Name: SORT-STRING Type purpose: To specify the text to be used in national language specific sorting of the values specified by the FN or N types. Type encoding: 8bit Type value: A single text value. Type special notes: The sort string is used to provide text that is to be used in locale- or national language-specific sorting of the values for the formatted name or structured name types. Without this information, sorting algorithms could incorrectly sort this vCard within a sequence of sorted vCards. If this type is present in a vCard, then this value should be used for sorting the vCard, instead of the values of the FN or N types. Type example: The following would define the sort string "Harten" for the "FN:Rene J. van der Harten" or "N:van der Harten;Rene;J.;Sir;R.D.O.N.". SORT-STRING:Harten 3.6.6 SOUND Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type SOUND Type name: SOUND Type purpose: To specify a digital sound content information that annotates some aspect of the vCard. By default this type is used to specify the proper pronunciation of the name type value of the vCard. Type 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. Type value: 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. Type special notes: The type can include the type parameter "TYPE" to specify the audio format type. The TYPE parameter values MUST be one of the IANA registered audio formats or a non-standard audio format.

Type encoding: 8bit Type value: A single text value. Type special notes: The type is used to uniquely identify the object that the vCard represents. The type can include the type parameter "TYPE" to specify the format of the identifier. The TYPE parameter value should be an IANA registered identifier format. The value can also be a non-standard format. Type example: UID:19950401-080045-40000F192713-0052 3.6.8 URL Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type URL Type name: URL Type purpose: To specify a uniform resource locator associated with the object that the vCard refers to. Type encoding: 8bit Type value: A single uri value. Type example: Dawson & Howes [Page 22] Expires January 1999 vCard MIME Directory Profile URL:http://www.swbyps.restaurant.french/~chezchic.html 3.6.9 VERSION Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type VERSION Type name: VERSION Type purpose: To specify the version of the vCard specification used to format this vCard. Type encoding: 8bit Type value: A single text value. Type special notes: The property MUST be present in the vCard object. The value MUST be "3.0" if the vCard corresponds to this specification. Type example: VERSION:3.0 3.7 Security Types These types are concerned with the security of communication pathways or access to the vCard. 3.7.1 CLASS Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type CLASS Type name: CLASS Type purpose: To specify the access classification for a vCard object. Type encoding: 8bit Type value: A single text value. Type 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. Type examples: CLASS:PUBLIC Dawson & Howes [Page 23] Expires January 1999 vCard MIME Directory Profile CLASS:PRIVATE CLASS:CONFIDENTIAL 3.7.2 KEY Type Definition To: ietf-mime-directory@imc.org Subject: Registration of text/directory MIME type KEY Type name: KEY Type purpose: To specify a public key or authentication certificate associated with the object that the vCard represents. Type 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. Type value: 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. Type special notes: The type can also include the type parameter TYPE to specify the public key or authentication certificate format. The parameter type should specify an IANA registered public key or authentication certificate format. The parameter type can also specify a non-standard format.

Differences From vCard v2.1 This specification has been reviewed by the IETF community. The review process introduced a number of differences from the [VCARD] version 2.1. These differences require that vCard objects conforming to this specification have a different version number than a vCard conforming to [VCARD]. The differences include the following: . The QUOTED-PRINTABLE inline encoding has been eliminated. Only the "B" encoding of [RFC 2047] is an allowed value for the ENCODING parameter. . The method for specifying CRLF character sequences in text type values has been changed. The CRLF character sequence in a text type value is specified with the backslash character sequence "\n" or "\N". . Any COMMA or SEMICOLON in a text type value must be backslash escaped. . VERSION value corresponding to this specification MUST be "3.0". . The [MIME-DIR] predefined types of SOURCE, NAME and PROFILE are allowed. . The [MIME-DIR] VALUE type parameter for value data typing is allowed. In addition, there are extensions made to these type values for additional value types used in this specification. . The [VCARD] CHARSET type parameter has been eliminated. Character set can only be specified on the CHARSET parameter on the Content-Type MIME header field. . The [VCARD] support for non-significant WSP character has been eliminated. . The "TYPE=" prefix to parameter values is required. In [VCARD] this was optional. . LOGO, PHOTO and SOUND multimedia formats MUST be either IANA registered types or non-standard types. . Inline binary content must be "B" encoded and folded. A blank line after the encoded binary content is no longer required. . TEL values can be identified as personal communication services telephone numbers with the PCS type parameter value. . The CATEGORIES, CLASS, NICKNAME, PRODID and SORT-STRING types have been added. . The VERSION, N and FN types MUST be specified in a vCard. This identifies the version of the specification that the Dawson & Howes [Page 34] Expires January 1999 vCard MIME Directory Profile object was formatted to. It also assures that every vCard will include both a structured and formatted name that can be used to identify the object. 6.

Security vCards can carry cryptographic keys or certificates, as described in Section 3.7.2. Section 3.7.1 specifies a desired security classification policy for a particular vCard. That policy is not enforced in any way. The vCard objects have no inherent authentication or privacy, but can easily be carried by any security mechanism that transfers MIME objects with authentication or privacy. In cases where threats of "spoofed" vCard information is a concern, the vCard SHOULD BE transported using one of these secure mechanisms. Dawson & Howes [Page 35] Expires January 1999 vCard MIME Directory Profile The information in a vCard may become out of date. In cases where the vitality of data is important to an originator of a vCard, the "URL" type described in section 3.6.8 SHOULD BE specified. In addition, the "REV" type described in section 3.6.4 can be specified to indicate the last time that the vCard data was updated. 9. authentication or privacy. 10.
