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].

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
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".
2.1.2 NAME Type
If the NAME type is present, then 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 is present, then its value MUST be "VCARD".
2.1.4 SOURCE Type
If the SOURCE type is present, then 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 except within the N,
NICKNAME, ADR and CATEGORIES value types.
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
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\, 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
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.
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 in the vCard
object.
Type example:
FN:Mr. John Q. Public\, 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.
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

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:1996-04-15
BDAY:1953-10-15T23:10:00Z
BDAY:1987-09-27T08:30:00-06:00
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.
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
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\, Esq.\n
Mail Drop: TNE QB\n123 Main Street\nAny Town\, CA 91921-1234

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

;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
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:
TITLE:Director\, 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 example:
LOGO;VALUE=uri:http://www.abc.com/pub/logos/abccorp.jpg
LOGO;ENCODING=b;TYPE=JPEG:MIICajCCAdOgAwIBAgICBEUwDQYJKoZIhvcN

3.5.4 AGENT Type Definition
To: ietf-mime-directory@imc.org
Subject: Registration of text/directory MIME type AGENT
Type name: AGENT
Type purpose: To specify information about another person who will
act on behalf of the individual or resource associated with the
vCard.
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-

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).
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.

REV:1997-11-15
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 family name or given name text to be
used for national-language-specific sorting of the FN and N types.
Type encoding: 8bit
Type value: A single text value.
Type 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 type is
present in a vCard, then this family name or given name value is used
for sorting the vCard.
Type examples: For the case of family name sorting, the following
examples define common sort string usage with the FN and N types.
FN:Rene van der Harten
N:van der Harten;Rene;J.;Sir;R.D.O.N.
SORT-STRING:Harten
FN:Robert Pau Shou Chang
N:Pau;Shou Chang;Robert

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 example:
SOUND;TYPE=BASIC;VALUE=uri:CID:JOHNQPUBLIC.part8.

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
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.

3.8 Extended Types
The types defined by this document can be extended with private types
using the non-standard, private values mechanism defined in [RFC
2045]. Non-standard, private types with a name starting with "X-" may
be defined bilaterally between two cooperating agents without outside
registration or standardization.
4. Formal Grammar
EID 1549 (Verified) is as follows:Section: 4
Original Text:
;For name="KEY"
[...]
key-bin-param = ("TYPE" "=" keytype)
/ ("ENCODING" "=" "b")
; Value MUST be a "b" encoded key or certificate
Corrected Text:
;For name="KEY"
[...]
key-bin-param = ("VALUE" "=" "binary")
/ ("TYPE" "=" keytype)
/ ("ENCODING" "=" "b")
; Value MUST be a "b" encoded key or certificate
Notes:
According to sections 2.4.1 and 3.7.2 the KEY type value can be specified as "binary".
EID 1551 (Verified) is as follows:Section: 4
Original Text:
;For name="EMAIL"
[...]
email-type = "INTERNET" / "X400" / iana-token / "X-" word
; Values are case insensitive
Corrected Text:
;For name="EMAIL"
[...]
email-type = "INTERNET" / "X400" / iana-token / x-name
; Values are case insensitive
Notes:
The email-type should contain a 'x-name' type instead of '"X-" word' for consistancy with tel-type, key-type and adr-type. Although "word" appears several times, it is not defined at all!
EID 868 (Verified) is as follows:Section: 4
Original Text:
;For name=3D"AGENT"
param =3D agent-inline-param
param =3D/ agent-refer-param
value =3D agent-inline-value
; Value and parameter MUST match
value =3D/ agent-refer-value
; Value and parameter MUST match
agent-inline-param =3D ""
; No parameters allowed
agent-refer-param =3D "VALUE" "=3D" "uri"
; Only value parameter allowed
agent-inline-value =3D text-value
; Value MUST be a valid vCard object
agent-refer-value =3D uri
; URI MUST refer to image content of given type
Corrected Text:
;For name=3D"AGENT"
param =3D agent-inline-param
param =3D/ agent-refer-param
value =3D agent-inline-value
; Value and parameter MUST match
value =3D/ agent-refer-value
; Value and parameter MUST match
agent-inline-param =3D ""
; No parameters allowed
agent-refer-param =3D "VALUE" "=3D" "uri"
; Only value parameter allowed
agent-inline-value =3D text-value
; Value MUST be a valid vCard object
agent-refer-value =3D uri
; URI MUST refer a valid vCard object
Notes:
- Presumably, the comment from img-refer-value was copied, but it was not modified. - The correction is consistent with comment for agent-inline-value. - The purpose of AGENT type is "To specify information about another person who will act on behalf of the individual or resource associated with the vCard." (Section 3.5.4)
EID 870 (Verified) is as follows:Section: 4
Original Text:
;For name=3D"UID"
param =3D ""
; No parameters allowed
value =3D text-value
Corrected Text:
;For name="UID"
param = "TYPE" "=" (iana-token / x-name)
; Only the TYPE parameter is allowed.
value = text-value
Notes:
Section 3.6.7 (p. 23) "UID Type Definition" says:
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.
Alexey: edited as per feedback from Simon Perreault.
Notes:
iana-type is not defined in given ABNF, but iana-token is. This is the only reference to iana-type in the document, so it is likely to be a typo.
iana-token =3D 1*(ALPHA / DIGIT / "-") ; vCard type or parameter identifier registered with IANA

5. 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
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.

8. Security Considerations
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.
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.
