Abstract
摘要
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.
本备忘录以 vCard 电子名片为基础，为白页个人对象的目录信息定义了 MIME 内容类型 [MIME-DIR] 的配置文件。该规范定义与任何特定的目录服务或协议无关。该配置文件用于表示和交换有关个人的各种信息（例如，格式化和结构化的姓名和送货地址、电子邮件地址、多个电话号码、照片、徽标、音频剪辑等）。该配置文件使用的目录信息基于 X.520 和 X.521 目录服务建议中定义的个人对象属性。本简介还提供了在[MIME-DIR]文档定义的 MIME 内容类型中包含白页目录条目的[VCARD]表示方法。
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].
本文档中的关键词 "MUST"、"MUST NOT"、"REQUIRED"、"SHALL"、"SHALL NOT"、"SHOULD"、"SHOULD NOT"、"RECOMMENDED"、"MAY "和 "OPTIONAL "应按照 [RFC 2119] 中的描述进行解释。

Overview
概述
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.
MIME-DIR] 文件定义了一种 MIME 内容类型，用于保存不同类型的目录信息。目录信息可以基于多种目录模式中的任何一种。本文件定义了一个 [MIME-DIR] 使用规范，用于传递基于其中一种模式的目录信息；即白页类型的个人对象。
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.
该模式以 X.520 和 X.521 目录服务建议中定义的人员对象属性为基础。该模式扩充了 X.500 系列建议中定义的基本属性，以提供纸质名片上常见信息的电子表示形式。该模式最初是在 [VCARD] 文档中定义的。因此，此 [MIME-DIR] 配置文件被称为 vCard MIME 目录配置文件。
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.
基于这种使用情况的通讯录条目可以包括传统的通讯录、白页信息，如用于唯一标识条目的尊贵名称、用于用户界面或展示目的的名称格式化表示、送达地址的结构化和展示形式、各种电话号码以及与条目相关的组织信息。此外，传统的纸质名片信息，如组织徽标的图像或识别照片，也可包含在此人 物中。
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].
vCard MIME 目录简介还支持表示与目录条目相关的个人的其他重要信息。例如，个人的出生日期；描述与目录条目相关的姓名发音的音频剪辑，或数字声音的其他应用；与目录条目相关的个人的经度和纬度地理定位信息；目录信息最后更新的日期和时间；通常写在名片上的注释；网站的统一资源定位符（URL）；公钥信息。该配置文件还为模式的非标准扩展提供支持。这为实施提供了灵活性，使其能以标准化的方式增强配置文件的现有功能。有关这种电子名片格式的更多信息，请参阅 [VCARD]。
This profile is identified by the following [MIME-DIR] registration template information. Subsequent sections define the profile definition.
本规范由以下 [MIME-DIR] 注册模板信息标识。随后的章节将定义该规范的定义。
Subject: Registration of text/directory MIME profile VCARD

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.
配置文件特别说明：vCard 对象必须包含 FN、N 和 VERSION 类型。本规范支持 [MIME-DIR] 的类型分组功能，可对目录条目的相关 vCard 属性进行分组。例如，描述与 "工作 "或 "家庭 "相关特征的 vCard 属性可使用唯一的组标签进行分组。
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.
本规范允许使用非标准类型（即前缀字符串为 "X-"的类型），作为一种灵活的实现方法，以扩展本规范当前定义的功能。
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].
vCard MIME Directory Profile 使用了 [MIME-DIR] 定义的许多功能。以下各节将阐明或扩展 [MIME-DIR] 的内容类型定义。
The vCard MIME Directory Profile uses the following predefined types from [MIME-DIR].
vCard MIME 目录规范使用 [MIME-DIR] 中的以下预定义类型。
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".
内容实体必须以 BEGIN 类型开始，其值为 "VCARD"。内容实体必须以 END 类型结束，其值为 "VCARD"。
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.
如果存在 NAME 类型，那么它的值就是与 SOURCE 类型中指定的 vCard 源相关联的可显示的演示文本。
If the PROFILE type is present, then its value MUST be "VCARD".
如果存在 PROFILE 类型，则其值必须为 "VCARD"。
If the SOURCE type is present, then its value provides information how to find the source for the vCard.
如果存在 SOURCE 类型，则其值将提供如何查找 vCard 来源的信息。
The vCard MIME Directory Profile uses the following predefined type parameters as defined by [MIME-DIR].
vCard MIME 目录规范使用 [MIME-DIR] 定义的以下预定义类型参数。
- LANGUAGE
- 语言
- ENCODING
- 编码
- VALUE
- 价值
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.
除 N、NICKNAME、ADR 和 CATEGORIES 值类型外，[MIME-DIR] 中指定的预定义数据类型值不得在 COMMA 分隔的值列表中重复。
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).
MIME-DIR] 中定义的文本值类型还受到进一步限制，即值中的任何 SEMI-COLON 字符（ASCII 十进制 59）都必须用 BACKSLASH 字符（ASCII 十进制 92）转义。
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.
vCard 配置文件对 [MIME-DIR] 中指定的预定义数据类型值进行了扩展，纳入了本配置文件特有的一些值类型。
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.
二进制 "值类型指定类型值为内联编码二进制数据。这种值类型可在照片、LOGO、声音和关键字类型中指定。
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].
如果指定内联编码二进制数据，则必须使用 ENCODING 类型参数来指定编码格式。二进制数据必须使用 "B "编码格式进行编码。长行编码二进制数据应使用 [MIME-DIR] 中定义的折叠方法折叠为 75 个字符。
The value type is defined by the following notation:
值类型由以下符号定义：
binary = <A "B" binary encoded string as defined by [RFC 2047].>
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:
vcard "值类型指定类型值是另一张 vCard。该值类型可在 AGENT 类型中指定。该值类型由本规范定义。由于 vcard 值类型中的每个类型声明都是在文本值本身中指定的，因此它们必须以反斜线转义序列"\n "或"\N "结束，而不是以正常换行符序列 CRLF 结束。此外，任何 COMMA 字符（ASCII 十进制 44）、SEMI-COLON 字符（ASCII 十进制 59）和 COLON 字符（ASCII 十进制 58）都必须用反斜线字符（ASCII 十进制 92）转义。例如，AGENT 类型的值可以指定为
AGENT:BEGIN:VCARD\nFN:Joe Friday\nTEL:+1-919-555-7878\n
TITLE:Area Administrator\, Assistant\n EMAIL\;TYPE=INTERN\n
ET:[email protected]\nEND:VCARD\n
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].
phone-number "值类型指定类型值为电话号码。该值类型可以在 TEL 类型中指定。该值类型是一个文本值，具有 [CCITT E.163] 和 [CCITT X.121] 中定义的电话号码的特殊语义。
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.
utc-offset"（UTC-偏移）值类型指定该类型值是从 UTC 的有符号偏移。该值类型可在 TZ 类型中指定。
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.
值类型是与协调世界时（UTC）的偏移量。它是以小时和分钟为单位的正负差值（例如，+hh:mm）。时间指定为 24 小时时钟。小时值从 00 到 23，分钟值从 00 到 59。小时和分钟均为两位数，为保持位数，需要高阶零。必须使用 ISO 8601 UTC 偏移的扩展格式。扩展格式使用冒号作为小时和分钟文本字段的分隔符。
The value is defined by the following notation:
该值由以下符号定义：
time-hour = 2DIGIT ;00-23
time-minute = 2DIGIT ;00-59
utc-offset = ("+" / "-") time-hour ":" time-minute
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).
复合类型值由字段分隔符分隔，分隔符由 SEMI-COLON 字符（ASCII 十进制 59）指定。复合属性值成分中的 SEMI-COLON 必须用 BACKSLASH 字符（ASCII 十进制 92）转义。
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).
数值列表由 COMMA 字符（ASCII 十进制 44）指定的列表分隔符分隔。数值中的 COMMA 字符必须用 BACKSLASH 字符（ASCII 十进制 92）转义。
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.
本简介支持 [MIME-DIR] 中定义的类型分组机制。对相关类型进行分组是一种有用的技术，可用于交流有关 vCard 属性的通用语义。
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].
本规范支持 [MIME-DIR] 中定义的相同行分隔和折叠方法。具体来说，在解析内容行时，折叠行必须首先按照 [MIME-DIR] 中描述的展开程序展开。生成内容行后，长度超过 75 个字符的行应按照 [MIME DIR] 中描述的折叠程序进行折叠。
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.
折叠在类型值的任何内容编码之后进行。展开是在对内容行中的类型值进行解码之前进行的。
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.
vCard MIME 目录简介类型包含目录信息，通常与单个目录条目有关。这些信息使用专门用于捕获个人联系信息的属性模式来描述。vCard 可包括描述与 vCard 相关联的特定对象的标识、交付地址、电信地址、地理、组织、一般说明、安全和访问信息的属性。
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.

Type value: A single structured text value, separated by the SEMI-COLON character (ASCII decimal 59).
类型值：单个结构化文本值，用 SEMI-COLON 字符分隔（ASCII 十进制 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.
类型特别说明：结构化类型值由一系列地址组件组成。必须在相应位置指定组件值。结构化类型值依次对应邮政信箱、扩展地址、街道地址、地点（如城市）、地区（如州或省）、邮政编码、国名。当缺少一个组件值时，仍必须指定相关的组件分隔符。
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).
文本组件之间用 SEMI-COLON 字符（ASCII 十进制 59）分隔。在语义合理的情况下，单个文本组件可以包含多个文本值（例如，一个 "街道 "组件包含多行），用 COMMA 字符（ASCII 十进制 44）分隔。
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".

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.
类型值：单个值。默认为二进制。也可以重置为文本值。文本值可用于指定文本键。
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.
类型特别说明：类型还可包括类型参数 TYPE，用于指定公钥或认证证书格式。参数类型应指定 IANA 注册的公钥或认证证书格式。参数类型也可指定非标准格式。

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.
本文档定义的类型可使用 [RFC 2045] 中定义的非标准私有值机制扩展为私有类型。名称以 "X-"开头的非标准私有类型可由两个合作代理双边定义，无需外部注册或标准化。

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:
本规范已由 IETF 社区审查。审查过程中引入了一些与 [VCARD] 2.1 版不同之处。这些差异要求符合本规范的 vCard 对象与符合 [VCARD] 的 vCard 具有不同的版本号。这些差异包括以下内容：
. The QUOTED-PRINTABLE inline encoding has been eliminated. Only the "B" encoding of [RFC 2047] is an allowed value for the ENCODING parameter.
.取消了 QUOTED-PRINTABLE 内联编码。ENCODING 参数只允许使用 [RFC 2047] 的 "B "编码。
. 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".
.更改了在文本类型值中指定 CRLF 字符序列的方法。文本类型值中的 CRLF 字符序列用反斜杠字符序列"\n "或"\N "指定。
. Any COMMA or SEMICOLON in a text type value must be backslash escaped.
.文本类型值中的任何 COMMA 或 SEMICOLON 必须使用反斜杠转义。
. VERSION value corresponding to this specification MUST be "3.0".
.与本规范相对应的版本值必须是 "3.0"。
. The [MIME-DIR] predefined types of SOURCE, NAME and PROFILE are allowed.
.允许使用 [MIME-DIR] 预定义的 SOURCE、NAME 和 PROFILE 类型。
. 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.
.允许使用用于值数据类型的 [MIME-DIR] VALUE 类型参数。此外，这些类型值还针对本规范中使用的其他值类型进行了扩展。
. 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.
.取消了 [VCARD] CHARSET 类型参数。字符集只能在 Content-Type MIME 头信息字段的 CHARSET 参数中指定。
. The [VCARD] support for non-significant WSP character has been eliminated.
.取消了 [VCARD] 对非重要 WSP 字符的支持。
. The "TYPE=" prefix to parameter values is required. In [VCARD] this was optional.
.参数值的前缀 "TYPE="是必需的。在 [VCARD] 中，这是可选项。
. LOGO, PHOTO and SOUND multimedia formats MUST be either IANA registered types or non-standard types.
.LOGO、PHOTO 和 SOUND 多媒体格式必须是 IANA 注册类型或非标准类型。
. Inline binary content must be "B" encoded and folded. A blank line after the encoded binary content is no longer required.
.内联二进制内容必须使用 "B "编码并折叠。编码后的二进制内容后不再需要空行。
. TEL values can be identified as personal communication services telephone numbers with the PCS type parameter value.
.TEL 值可通过 PCS 类型参数值识别为个人通信服务电话号码。
. The CATEGORIES, CLASS, NICKNAME, PRODID and SORT-STRING types have been added.
.添加了 CATEGORIES、CLASS、NICKNAME、PRODID 和 SORT-STRING 类型。
. 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.
.VERSION、N 和 FN 类型必须在 vCard 中指定。这可以识别对象格式化所遵循的规范版本。它还确保每张 vCard 都包含一个结构化和格式化的名称，可用于识别对象。

vCards can carry cryptographic keys or certificates, as described in Section 3.7.2.
如第 3.7.2 节所述，vCard 可以携带加密密钥或证书。
Section 3.7.1 specifies a desired security classification policy for a particular vCard. That policy is not enforced in any way.
第 3.7.1 节规定了特定 vCard 所需的安全分类策略。该策略不会以任何方式强制执行。
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.
vCard 对象本身没有验证或保密功能，但可以很容易地通过任何传输带验证或保密功能的 MIME 对象的安全机制进行传输。如果 vCard 信息受到 "欺骗 "的威胁，vCard 应使用这些安全机制之一进行传输。
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.
vCard 中的信息可能会过时。如果数据的生命力对 vCard 的创建者很重要，那么就应该指定第 3.6.8 节所述的 "URL "类型。此外，还可以指定第 3.6.4 节所述的 "REV "类型，以表示 vCard 数据的最后更新时间。
