Declaration of structure:

结构声明:

The identifier structure is as follows:

标识符结构如下所示:

         URN:ISAN:<ISAN-NSS>
        
         URN:ISAN:<ISAN-NSS>
        

Where ISAN-NSS is conformant to URN syntax requirements defined in [RFC2141] and is further constrained by [ISO15706] and in this document. There are two forms, one with the version extension and one without. The formal BNF is defined in section 2 below. Examples of the two forms are:

其中,ISAN-NSS符合[RFC2141]中定义的URN语法要求,并进一步受到[ISO15706]和本文件的约束。有两种形式,一种有版本扩展,另一种没有。正式的BNF定义见下文第2节。这两种形式的示例如下:

URN:ISAN:0123-1230-3210-2310-1

URN:ISAN:0123-1230-3210-2310-1

URN:ISAN:1881-66C7-3420-6541-9-9F3A-0245-U

URN:ISAN:1881-66C7-3420-6541-9-9F3A-0245-U

Relevant ancillary documentation:

相关辅助文件:

ISAN, its syntax, uses and its processes are defined in [ISO15706].

ISAN及其语法、用途和过程在[ISO15706]中有定义。

Identifier uniqueness considerations:

标识符唯一性注意事项:

Uniqueness is guaranteed by the ISAN International Agency that issues the numbers. Numbers are not re-assigned.

唯一性由发布数字的ISAN国际机构保证。号码不会被重新分配。

Identifier persistence considerations:

标识符持久性注意事项:

Persistence is guaranteed by ISO Registration Authority processes and contracts with the ISAN International Agency.

ISO注册机构流程和与ISAN国际机构签订的合同保证了持久性。

Process of identifier assignment:

标识符分配过程:

The details of the assignment process are defined from time to time by the ISAN International Agency. However, in general, any approved entity can request an ISAN number by providing the required metadata information and paying the registration fee. The ISAN International Agency may delegate to regional or market-based Registration Agencies for portions of the registration process.

ISAN国际机构不时对派遣过程的细节进行定义。但是,一般来说,任何经批准的实体都可以通过提供所需的元数据信息和支付注册费来申请ISAN号码。ISAN国际机构可授权区域或市场注册机构参与部分注册过程。

Process for identifier resolution:

标识符解析过程:

ISAN numbers are resolved by a direct or indirect lookup with the ISAN International Agency. At this writing, a non-commercial, manual system is available online at http://www.isan.org. The resolution procedures may be modified from time to time by the ISAN International Agency.

ISAN编号由ISAN国际机构通过直接或间接查找解决。在撰写本文时,一个非商业性的手动系统可在线访问http://www.isan.org. ISAN国际机构可不时修改处置程序。

Rules for Lexical Equivalence:

词汇对等规则:

The ISAN-NSS is unique by the nature of the ISAN International Agency's number management. The ISAN-NSS is case-insensitive. Upper and lower case characters are treated as identical.

ISAN-NSS因其国际机构号码管理的性质而独特。ISAN-NSS不区分大小写。大写和小写字符被视为相同。

Conformance with URN Syntax:

符合URN语法:

No special considerations. The syntax is fully conformant with [RFC2141].

没有特别考虑。语法完全符合[RFC2141]。

Validation mechanism:

验证机制:

The check digits provide syntax integrity. Lookup is via online and offline services provided by the ISAN International Agency.

检查数字提供语法完整性。通过ISAN国际机构提供的在线和离线服务进行查找。

Scope: Global.

经营范围:全球。

3. Formal Syntax
3. 形式语法

The following syntax specification uses an augmented Backus-Naur Form (BNF) and elements defined in the URN Syntax [RFC2141]. This syntax here is derived from the syntax definition in [ISO15706], constrained to prohibit the space character as a separator.

下面的语法规范使用了扩展的Backus Naur表单(BNF)和URN语法[RFC2141]中定义的元素。此语法源自[ISO15706]中的语法定义,限制为禁止空格字符作为分隔符。

      <ISAN-NSS>     ::= <root> <episode> [version]
        
      <ISAN-NSS>     ::= <root> <episode> [version]
        
      <root>         ::= 3*(<hexnum> "-")
        
      <root>         ::= 3*(<hexnum> "-")
        
      <episode>      ::= <hexnum> "-" <check>
        
      <episode>      ::= <hexnum> "-" <check>
        
      <version>      ::= 2*("-" <hexnum>) "-" <check>
        
      <version>      ::= 2*("-" <hexnum>) "-" <check>
        
      <hexnum>       ::= 4*(<hex>)
        
      <hexnum>       ::= 4*(<hex>)
        
      <check>        ::= <upper> | <lower> | <number>
        
      <check>        ::= <upper> | <lower> | <number>
        

Note that <hex>, <upper>, <lower>, and <number> are defined in [RFC2141].

请注意,<hex>、<upper>、<lower>和<number>在[RFC2141]中定义。

4. Security Considerations
4. 安全考虑

This document only defines the syntax and resolution authority for the ISAN numbers. Details of the resolution process and the security of the assignment and resolution system processes are defined external to this document by the ISAN International Agency and thus outside the scope of this document.

本文档仅定义ISAN编号的语法和解析权限。处置过程的细节以及分配和处置系统过程的安全性由ISAN国际机构在本文件之外定义,因此不在本文件范围内。

5. Namespace Considerations
5. 命名空间注意事项

ISAN is an external numbering system managed by an external agency established by ISO. While URN namespaces may exist for which any generic numbering system can be encoded, there is currently no direct encoding for ISAN. An example of such a namespace is the MPEG-21 system.

ISAN是由ISO建立的外部机构管理的外部编号系统。虽然可能存在任何通用编号系统都可以编码的URN名称空间,但目前没有ISAN的直接编码。这种名称空间的一个例子是MPEG-21系统。

ISAN numbers are reserved for use in identifying audiovisual works for which there is a moving visual component, or components related to such a work (e.g. subtitling track).

ISAN编号保留用于识别有移动视觉组件的视听作品,或与此类作品相关的组件(例如字幕轨道)。

6. Community Considerations
6. 社区考虑

The primary registrants for ISAN numbers are the producers and studios of audiovisual works (movies and television shows). While the system is not constrained to "major" works (any bona fide entity can register any work), the primary benefits of its use come from

ISAN号码的主要注册人是视听作品(电影和电视节目)的制作人和工作室。虽然该系统不局限于“重大”作品(任何真正的实体都可以注册任何作品),但其使用的主要好处来自

works that are widely distributed. The users of the ISAN system range from the studios themselves to film and video archives and libraries, rights administrators, program guide services, and audience measurement services. Its potential for use in the Internet community is as an identifier for streaming media.

广泛发行的作品。ISAN系统的用户范围从制片厂本身到电影和视频档案馆和图书馆、版权管理员、节目指南服务和观众测量服务。它在互联网社区中的潜在用途是作为流媒体的标识符。

7. IANA Considerations
7. IANA考虑

This document defines a URN NID registration that is to be entered into the IANA registry of URN NIDs. It specifically requests the NID, "ISAN".

本文档定义了URN NID注册,该注册将输入URN NID的IANA注册表。它特别要求NID“ISAN”。
