This document defines the formal Uniform Resource Name (URN) Namespace Identifier (NID) for Ad-IDs.
本文档定义了Ad ID的正式统一资源名（URN）命名空间标识符（NID）。
Ad-ID is the industry standard for identifying advertising assets across all media platforms (e.g., over the air, online, over the top, mobile, and place based). Ad-IDs are unique codes for each creative advertising asset. Those unique codes are applied to all media.
Ad ID是识别所有媒体平台（如空中、在线、无线、移动和基于地点）广告资产的行业标准。广告ID是每个创意广告资产的唯一代码。这些唯一代码适用于所有介质。
Ad-IDs are an eleven-character ASCII string except for High Definition (HD) or Three-Dimensional (3D) codes, which have an H or D as the 12th character.
Ad ID是11个字符的ASCII字符串，但高清（HD）或三维（3D）代码除外，其第12个字符为H或D。
Ad-ID also provides descriptive metadata about the advertisement. The metadata includes the advertiser, brand, product, commercial title, product categorization, and other essential data about the advertisement. The metadata can be retrieved using the unique code.
Ad ID还提供有关广告的描述性元数据。元数据包括广告客户、品牌、产品、商业名称、产品分类以及其他有关广告的基本数据。可以使用唯一代码检索元数据。
See Appendix A for additional background information.

Declaration of syntactic structure:
句法结构声明：
The identifier structure is an Ad-ID that consists of a unique eleven-character string or a unique twelve-character string (video codes only).
标识符结构是由唯一的11个字符字符串或唯一的12个字符字符串（仅视频代码）组成的Ad ID。
This string is divided into three parts:
该字符串分为三个部分：
1. A four-character alphanumeric Company Prefix, not starting with "0" 2. A seven-character alphanumeric code 3. An optional one-character Video Format Identifier. H - High Definition D - Three-Dimensional
1. 四个字符的字母数字公司前缀，不以“0”2开头。七个字符的字母数字代码3。可选的单字符视频格式标识符。H-高清D-三维
The URN representation URN-ADID of an Ad-ID conforms to the following syntax (expressed using ABNF [RFC5234]):
Ad ID的URN表示URN-ADID符合以下语法（使用ABNF[RFC5234]表示）：
URN-ADID = "urn:adid:" full-adid-identifier
full-adid-identifier =
full-adid-prefix full-adid-code [full-adid-suffix]
full-adid-prefix = (ALPHA / %x31-39) 3*alphanum
full-adid-code = 7*alphanum
full-adid-suffix = "H" / "D"
alphanum = ALPHA / DIGIT
URN-ADID = "urn:adid:" full-adid-identifier
full-adid-identifier =
full-adid-prefix full-adid-code [full-adid-suffix]
full-adid-prefix = (ALPHA / %x31-39) 3*alphanum
full-adid-code = 7*alphanum
full-adid-suffix = "H" / "D"
alphanum = ALPHA / DIGIT

示例：
Standard Definition: urn:adid:ABCD0001000

[SMPTERP2092-1]指定广告数字标识符（Ad ID）表示。
Identifier uniqueness considerations:
标识符唯一性注意事项：
The Registrar (Advertising Digital Identification, LLC) is responsible for managing the assignment of the Ad-ID and shall ensure its uniqueness by checking the identifier against the list of existing identifiers. In addition, each Ad-ID is associated with a its own unique URN-ADID.
注册官（广告数字标识有限责任公司）负责管理广告标识的分配，并应通过对照现有标识列表检查标识来确保其唯一性。此外，每个Ad ID都与一个特定的URN-ADID关联。
Ad-ID Registrar has assigned "adid" as a unique identifier. It is associated with a single URN-ADID.
Ad ID注册器已将“adid”指定为唯一标识符。它与一个URN-ADID关联。
Identifier persistence considerations:
标识符持久性注意事项：
The assignment process guarantees that 'adids' will not be reassigned or reused, and the binding between the identifier and its resource is permanent.
分配过程保证不会重新分配或重用“ADID”，并且标识符与其资源之间的绑定是永久性的。
These rules apply to this URN namespace.
这些规则适用于此URN命名空间。
Process of identifier assignment:
标识符分配过程：
Ad-IDs are generated by the Ad-ID's proprietary registration procedures.
Ad ID由Ad ID的专有注册程序生成。
Process for identifier resolution:
标识符解析过程：
Ad-ID URNs are resolved via URN resolvers that are maintained by the Ad-ID.
Ad ID URN通过Ad-ID维护的URN解析程序解析。
Rules for Lexical Equivalence:
词汇对等规则：
Lexical equivalence of URN-ADID is defined by case-insensitive string match.
URN-ADID的词汇等价性由不区分大小写的字符串匹配定义。
Conformance with URN Syntax:
符合URN语法：
As specified above, the syntax of URN-ADID is a subset of the URN syntax specified in [RFC2141].
如上所述，URN-ADID的语法是[RFC2141]中指定的URN语法的子集。
Validation mechanism:
验证机制：
The validity of a URN-ADID can be checked using Ad-ID's web services. For more information on Ad-ID's web services, please refer to the following links:
可以使用Ad ID的web服务检查URN-ADID的有效性。有关Ad ID web服务的更多信息，请参阅以下链接：

Scope:
范围：
Ad-IDs are centrally registered, globally unique identifiers of advertising assets that are used worldwide.
广告ID是在全球范围内使用的广告资产的集中注册的全球唯一标识符。
Ad-IDs are intended for use in Internet applications, where URNs are routinely used to identify audiovisual resources. There is no direct mapping from Ad-IDs to existing URN namespaces.
Ad ID用于互联网应用，其中URN通常用于识别视听资源。没有从Ad ID到现有URN名称空间的直接映射。
The primary registrants of Ad-IDs are advertisers and agencies. Ad-IDs can be used by anyone to unambiguously identify advertising assets and retrieve underlying metadata. The primary benefits of its use are providing greater transparency and accountability in the advertising marketplace, helping to eliminate costly errors associated with the inconsistent use of advertising-asset identifiers throughout the advertising supply chain, and enabling a more granular audience measurement across multiple platforms.
广告ID的主要注册人是广告商和代理商。任何人都可以使用广告ID来明确标识广告资产并检索底层元数据。其使用的主要好处是在广告市场中提供更大的透明度和问责制，有助于消除与整个广告供应链中广告资产标识符使用不一致相关的代价高昂的错误，并实现跨多个平台的更精细的受众测量。
This document specifies the syntax of the Ad-ID URN namespace and makes no security representations. However, note that failure to conform to the syntactic and lexical equivalence rules specified in [RFC3406] when using an Ad-ID as a criterion for accessing restricted resources can result in granting unauthorized access.
本文档指定Ad ID URN名称空间的语法，不提供任何安全表示。但是，请注意，当使用Ad ID作为访问受限资源的标准时，如果不遵守[RFC3406]中规定的语法和词汇等效规则，可能会导致授予未经授权的访问权限。

Ad ID是11个字符的ASCII字符串，但高清（HD）或三维（3D）代码除外，其第12个字符为H或D。
Ad-ID may have Complimentary Definition Codes (CDCs), which are matching SD, HD, and/or 3D codes where only the 12th character of the code varies. This only applies to video codes.
Ad ID可能有补充定义码（CDC），它与SD、HD和/或3D代码匹配，其中只有代码的第12个字符不同。这仅适用于视频代码。
For example, a video with a standard format and high-definition format would have a single code for each format.
例如，具有标准格式和高清晰度格式的视频每种格式都有一个代码。
Standard: ABCD1234000 High Definition: ABCD1234000H
标准：ABCD1234000高清：ABCD1234000H
