Version 4 of the vCard specification [RFC6350] defines a new KIND property to specify the type of entity that a vCard represents. During its work on the base vCard4 specification, the VCARDDAV Working Group defined values of "individual", "organization", "group", and "location" for the KIND property. The working group considered but then removed a value of "thing" to represent any type of physical entity, machine, software application, etc., with the expectation that such a value might be defined in a vCard extension. This document does not define a generic "thing" value but instead defines a more narrow "application" value so that vCards can be used to represent software applications.
vCard规范的第4版[RFC6350]定义了一个新的种类属性，用于指定vCard表示的实体类型。VCARDDAV工作组在其基础vCard4规范的工作中，为实物属性定义了“个人”、“组织”、“组”和“位置”的值。工作组考虑了表示任何类型的物理实体、机器、软件应用程序等的“thing”值，但随后删除了该值，并期望该值可以在vCard扩展中定义。本文档没有定义通用的“thing”值，而是定义了一个更窄的“application”值，以便vCard可以用来表示软件应用程序。
When the KIND property has a value of "application", the vCard
represents a software application such as a server, an online service
(e.g., a chat room), or an automated software bot. More formally, an
"application" is functionally equivalent to the 'applicationProcess'
object class used in the Lightweight Directory Access Protocol
[RFC4519] as derived from the Open Systems Interconnection model
[X.521] [X.200]. As one example of the "application" KIND, vCards
are currently used in the Extensible Messaging and Presence Protocol
[RFC6120] to represent instant messaging servers that are deployed on
the network.
When the KIND property has a value of "application", the vCard

are currently used in the Extensible Messaging and Presence Protocol
[RFC6120] to represent instant messaging servers that are deployed on
the network.
The properties included in an application's vCard apply to one of the following:
应用程序vCard中包含的属性适用于以下任一项：
o The application itself (e.g., the FN property might represent the friendly name of an application service, the URL property might represent a website that contains further information about the service, and the ADR, GEO, and TZ properties might represent the physical address, geographical location, and time zone of the machine where the service is hosted).
o 应用程序本身（例如，FN属性可能表示应用程序服务的友好名称，URL属性可能表示包含有关服务的进一步信息的网站，ADR、GEO和TZ属性可能表示托管服务的机器的物理地址、地理位置和时区）。
o An organization or person that makes the application available on the network (e.g., the LOGO property might represent the corporate logo of a service provider).
o 使应用程序在网络上可用的组织或个人（例如，LOGO属性可能代表服务提供商的公司徽标）。
o A person or role that maintains the application (e.g., the TEL, EMAIL, and IMPP properties might represent ways to contact a server administrator).
o 维护应用程序的人员或角色（例如，TEL、EMAIL和IMPP属性可能代表联系服务器管理员的方式）。
When a property represents some aspect of the application itself, it makes no sense to include the "work" and "home" values of the TYPE parameter since software applications do not have work places and personal lives (see the definition of the TYPE parameter in Section 5.6 of [RFC6350]). When a property represents information about an individual associated with the application (e.g., an individual service administrator as opposed to a generic service administrator role or an associated organization), inclusion of the "work" and "home" values can be appropriate.
当一个属性表示应用程序本身的某个方面时，由于软件应用程序没有工作场所和个人生活（请参见[RFC6350]第5.6节中类型参数的定义），因此包含类型参数的“工作”和“家庭”值是没有意义的。当属性表示与应用程序关联的个人（例如，与通用服务管理员角色或关联组织相对的个人服务管理员）的信息时，可以适当地包含“工作”和“家庭”值。
The following base properties make sense for vCards that represent software applications (this list is not exhaustive, and other properties might be applicable as well):
以下基本属性对于表示软件应用程序的vCard是有意义的（此列表并不详尽，其他属性也可能适用）：
o ADR o EMAIL o FN o GEO o IMPP o KEY o KIND o LANG o LOGO o NOTE o ORG o PHOTO o REV o SOURCE o TEL o TZ o URL
o ADR o电子邮件o FN o GEO IMP o KEY o KIND o LANG o LOGO NOTE o ORG o PHOTO REV o SOURCE o TEL o TZ o URL
Although it might be desirable to define a more fine-grained taxonomy of applications (e.g., a KIND of "application" with a subtype of "server" or "IM server"), such a taxonomy is out of the scope of this document.
尽管可能需要定义更细粒度的应用程序分类法（例如，一种子类型为“服务器”或“IM服务器”的“应用程序”），但这种分类法不在本文档的范围之内。
The following example of an Extensible Messaging and Presence Protocol (XMPP) server is borrowed from [XEP-0292]. The XML representation of the vCard is described in [RFC6351], which allows for the use of the new "application" value using the "iana-token" production defined in [RFC6350].
以下可扩展消息和状态协议（XMPP）服务器的示例借用自[XEP-0292]。[RFC6351]中描述了vCard的XML表示形式，允许使用[RFC6350]中定义的“iana令牌”产品使用新的“应用程序”值。

IANA has added "application" to the registry of property values for vCard4. In conformance with Section 10.2.6 of [RFC6350], the registration is as follows, where the reference is to RFC 6473.
IANA已将“应用程序”添加到vCard4的属性值注册表中。根据[RFC6350]第10.2.6节，注册如下，参考RFC 6473。
Value: application
价值：应用
Purpose: The entity represented by the vCard is a software application (e.g., a server, an online service such as a chat room, or an automated software bot).
用途：vCard所代表的实体是软件应用程序（例如，服务器、在线服务（如聊天室）或自动化软件机器人）。
Conformance: This value can be used with the KIND property.
一致性：此值可与KIND属性一起使用。
Example: See Section 3 of RFC 6473.
示例：参见RFC 6473第3节。
Use of vCards to represent software applications is not envisioned to introduce security considerations beyond those specified for vCards in general as described in [RFC6350].
使用vCard来表示软件应用程序并不是为了在[RFC6350]中所述的vCard一般规定之外引入安全注意事项。
