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.
此备忘录定义了基于vCard电子名片的white pages person对象目录信息的MIME内容类型[MIME-DIR]的配置文件。配置文件定义独立于任何特定的目录服务或协议。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递送地址、电子邮件地址、多个电话号码、照片、徽标、音频剪辑等）。此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person对象的属性。配置文件还提供了在[MIME-DIR]文档定义的MIME内容类型中包含白页目录项的[VCARD]表示的方法。
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].
本文件中的关键词“必须”、“不得”、“要求”、“应”、“不应”、“应”、“不应”、“建议”、“可”和“可选”应按照[RFC 2119]中所述进行解释。

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]文档定义了用于保存不同类型目录信息的MIME内容类型。目录信息可以基于多个目录模式中的任意一个。本文档定义了一个[MIME-DIR]使用配置文件，用于基于一个这样的模式传输目录信息；person对象的白页类型。
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.
模式基于X.520和X.521目录服务建议中定义的person对象的属性。该模式扩展了X.500系列建议中定义的基本属性，以便提供纸质名片上常见信息的电子表示。此架构首先在[VCARD]文档中定义。因此，此[MIME-DIR]配置文件称为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.
基于此使用配置文件的目录条目可以包括传统目录、白页信息，例如用于唯一标识条目的可分辨名称、用于用户界面或演示目的的名称的格式化表示、递送地址的结构化和演示形式，与条目相关的各种电话号码和组织信息。此外，此person对象中还可以包含传统纸质名片信息，例如组织徽标的图像或识别照片。
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
vCard MIME目录配置文件还支持表示与目录项关联的人员的其他重要信息。例如，此人的出生日期；一种音频剪辑，描述与目录项或目录的某些其他应用程序相关联的名称的发音
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].
数字声音；与目录条目关联的人员相关的经度和纬度地理定位信息；上次更新目录信息的日期和时间；通常写在名片上的注解；网站的统一资源定位器（URL）；公开密钥信息。该概要文件还支持模式的非标准扩展。这为实现提供了灵活性，以标准化的方式增强概要文件的当前功能。有关此电子名片格式的更多信息，请参见[VCARD]。
This profile is identified by the following [MIME-DIR] registration template information. Subsequent sections define the profile definition.

进入例如，描述工作或家庭相关特征的vCard属性可以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.
该概要文件允许使用非标准类型（即，使用前缀字符串“X-”）标识的类型）作为实现扩展当前在此概要文件中定义的功能的灵活方法。
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目录配置文件使用了[MIME-DIR]定义的许多功能。以下各节阐明或扩展[MIME-DIR]的内容类型定义。
The vCard MIME Directory Profile uses the following predefined types from [MIME-DIR].
vCard MIME目录配置文件使用[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".
内容实体必须以值为“VCARD”的begin类型开头。内容实体必须以值为“VCARD”的结束类型结尾。
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.
如果名称类型存在，则其值为与vCard源关联的可显示演示文本，如源类型中指定的。
If the PROFILE type is present, then its value MUST be "VCARD".
如果存在配置文件类型，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.
如果存在源类型，则其值提供如何查找vCard源的信息。
The vCard MIME Directory Profile uses the following predefined type parameters as defined by [MIME-DIR].
vCard MIME目录配置文件使用[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.
[MIME-DIR]中指定的预定义数据类型值不得在逗号分隔的值列表中重复，N、昵称、ADR和类别值类型除外。
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受到进一步限制，因此值中的任何分号字符（ASCII十进制59）必须用反斜杠字符（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配置文件扩展了[MIME-DIR]中指定的预定义数据类型值，以包括特定于此配置文件的许多值类型。
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的二进制数据。可以在照片、徽标、声音和按键类型中指定此值类型。
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].
如果指定了内联编码的二进制数据，则必须使用ENCODING type参数指定编码格式。二进制数据必须使用“B”编码格式进行编码。应使用[MIME-DIR]中定义的折叠方法将编码的二进制数据的长行折叠为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].>
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
“vcard”值类型指定类型值是另一个vcard。可以在代理类型中指定此值类型。值类型由本规范定义。因为每种类型
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:
如果要在文本值本身中指定vcard值类型中包含的声明，则必须使用反斜杠转义序列“\n”或“\n”来终止声明，而不是使用正常的换行符序列CRLF。此外，任何逗号字符（ASCII十进制44）、分号字符（ASCII十进制59）和冒号字符（ASCII十进制58）必须用反斜杠字符（ASCII十进制92）转义。例如，对于代理类型，值将指定为：
AGENT:BEGIN:VCARD\nFN:Joe Friday\nTEL:+1-919-555-7878\n
TITLE:Area Administrator\, Assistant\n EMAIL\;TYPE=INTERN\n
ET:jfriday@host.com\nEND:VCARD\n
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
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].
“电话号码”值类型指定类型值为电话号码。可以在TEL类型中指定此值类型。值类型是具有[CCITT E.163]和[CCITT X.121]中定义的电话号码特殊语义的文本值。
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偏移量”值类型指定类型值是utc的有符号偏移量。可以在TZ类型中指定此值类型。
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。它被指定为以小时和分钟为单位的正差或负差（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。小时和分钟为2位数字，需要高阶零来保持数字计数。必须使用ISO 8601 UTC偏移量的扩展格式。扩展格式使用冒号字符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
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).
复合类型值由分号字符（ASCII十进制59）指定的字段分隔符分隔。复合属性值组件中的分号必须使用反斜杠字符（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).
值列表由逗号字符（ASCII十进制44）指定的列表分隔符分隔。值中的逗号字符必须用反斜杠字符（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.
此配置文件支持[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，用于传达有关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].
此配置文件支持[MIME-DIR]中定义的相同的线分隔和折叠方法。具体来说，在解析内容行时，必须首先根据[MIME-DIR]中描述的展开过程展开折叠的行。生成内容行后，应根据[MIME DIR]中描述的折叠过程折叠长度超过75个字符的行。
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.
折叠是在对类型值进行任何内容编码之后完成的。展开是在对内容行中的类型值进行任何解码之前完成的。
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目录配置文件类型包含目录信息，通常与单个目录条目有关。使用为捕获个人联系信息而定制的属性模式来描述信息。vCard可以包括描述与vCard相关联的特定对象的标识、交付寻址、电信寻址、地理、组织、一般解释和安全以及访问信息的属性。
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.
这些类型在vCard配置文件中用于捕获与vCard关联的人员或资源的标识和命名相关的信息。

Subject: Registration of text/directory MIME type SORT-STRING
主题：文本/目录MIME类型排序字符串的注册
Type Name: SORT-STRING
类型名称：排序字符串
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.
类型用途：指定用于FN和N类型的国家语言特定排序的族名称或给定名称文本。
Type encoding: 8bit
类型编码：8位
Type value: A single text value.
类型值：单个文本值。
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.
类型特殊注释：排序字符串用于提供在格式化名称和结构化名称类型的区域设置或国家语言特定排序中使用的族名称或给定名称文本。如果没有这些信息，排序算法可能会在已排序的vCard序列中错误地排序此vCard。当vCard中存在此类型时，将使用此族名称或给定名称值对vCard进行排序。
Type examples: For the case of family name sorting, the following examples define common sort string usage with the FN and N types.
类型示例：对于姓氏排序，以下示例定义了FN和N类型的常用排序字符串用法。

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以使用[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以在两个合作代理之间双边定义，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。审查过程引入了与[VCARD]2.1版的一些差异。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：
. The QUOTED-PRINTABLE inline encoding has been eliminated. Only the "B" encoding of [RFC 2047] is an allowed value for the ENCODING parameter.
. 已消除引用的可打印内联编码。编码参数只允许使用[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".
. 在文本类型值中指定CRLF字符序列的方法已更改。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逗号或分号都必须反斜杠转义。
. VERSION value corresponding to this specification MUST be "3.0".
. 与本规范对应的版本值必须为“3.0”。
. The [MIME-DIR] predefined types of SOURCE, NAME and PROFILE are allowed.
. 允许[MIME-DIR]预定义的源、名称和配置文件类型。
. 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[MIME-DIR]值类型参数来键入值数据。此外，对于本规范中使用的附加值类型，还对这些类型值进行了扩展。
. 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.
. [VCARD]字符集类型参数已被删除。只能在内容类型MIME标头字段的CHARSET参数上指定字符集。
. The [VCARD] support for non-significant WSP character has been eliminated.
. 已取消对非重要WSP字符的[VCARD]支持。
. The "TYPE=" prefix to parameter values is required. In [VCARD] this was optional.
. 参数值的“TYPE=”前缀是必需的。在[VCARD]中，这是可选的。
. LOGO, PHOTO and SOUND multimedia formats MUST be either IANA registered types or non-standard types.
. 徽标、照片和声音多媒体格式必须是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进行“B”编码和折叠。编码的二进制内容后不再需要一个空行。
. TEL values can be identified as personal communication services telephone numbers with the PCS type parameter value.
. TEL值可以通过PCS type参数值标识为个人通信服务电话号码。
. The CATEGORIES, CLASS, NICKNAME, PRODID and SORT-STRING types have been added.
. 添加了类别、类、昵称、PRODID和排序字符串类型。
. 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.
. 必须在vCard中指定版本、N和FN类型。这标识对象格式化为的规范版本。它还确保每个vCard都包含可用于标识对象的结构化和格式化名称。
