Specification 1000D [1] (S1000D) is an international specification for the procurement and production of technical publications. The current issue of the specification has been jointly produced by the Aerospace and Defence Industries Association of Europe (ASD; previously AECMA, European Association of Aerospace Industries) and the Aerospace Industries Association of America (AIA). The specification is used worldwide by a variety of commercial and government entities for the development of technical documentation.
规范1000D[1]（S1000D）是技术出版物采购和生产的国际规范。本规范的最新版本由欧洲航空航天和国防工业协会（ASD；之前为AECMA，欧洲航空航天工业协会）和美国航空航天工业协会（AIA）联合编制。本规范在世界范围内被各种商业和政府实体用于技术文件的编制。
The specification adopts ISO, Computer-Aided Acquisition and Life-Cycle Support (CALS), and W3C standards to promote document standardization in which information is generated in a neutral format. Compliant documentation generated using the specification can be processed on different, and often disparate, IT systems. It is this feature, added to the concept of modularization, that makes the specification acceptable to the wider international community.
该规范采用ISO、计算机辅助采集和生命周期支持（CALS）以及W3C标准来促进文档标准化，其中信息以中性格式生成。使用规范生成的符合规范的文档可以在不同的IT系统上进行处理，这些系统通常是完全不同的。正是这个特性，加上模块化的概念，使得规范被更广泛的国际社会所接受。
Portions of S1000D define a resource coding system allowing resources created under the specification to be uniquely identified in global environment. To provide for the creation of a web-based resource management system, ASD would like to assign URNs [2][3][4] to resources created under the specification in order to retain unique, permanent, location-independent names for these resources, in addition to providing a framework for resolution of these resources.
S1000D的部分定义了一个资源编码系统，允许在全球环境中唯一标识根据规范创建的资源。为了建立一个基于网络的资源管理系统，ASD希望将URN[2][3][4]分配给根据规范创建的资源，以便为这些资源保留唯一、永久、独立于位置的名称，此外还提供了解决这些资源的框架。

Identifier uniqueness considerations:
标识符唯一性注意事项：
Identifier uniqueness is guaranteed through processes outlined within ASD S1000D. All codes defined within the specification must begin with a Model Identifier (MI) that will be registered with the NATO Maintenance and Supply Agency (NAMSA) and is never to be reused. All project-generated codes are prefixed by the assigned MI and are required by the specification to be unique within the scope of the project. Since all project codes are prefixed by a globally unique MI, and since these codes must be unique within the project, all generated identifiers will be globally unique.
通过ASD S1000D中概述的过程保证标识符的唯一性。本规范中定义的所有代码必须以型号标识符（MI）开头，该标识符将在北约维修和供应局（NAMSA）注册，且不得重复使用。所有项目生成的代码都以指定的MI为前缀，规范要求这些代码在项目范围内是唯一的。由于所有项目代码的前缀都是全局唯一的MI，并且这些代码在项目中必须是唯一的，因此所有生成的标识符都是全局唯一的。
Identifier persistence considerations:
标识符持久性注意事项：
Persistence of identifiers is dependent upon suitable delegation of resolution and the fact that generated identifiers are to be persistent once published. Existing information objects can be used in new projects by referencing them through their persistent identifiers.
标识符的持久性取决于适当的解析委托，以及生成的标识符在发布后将持久化的事实。现有信息对象可以通过其持久标识符引用到新项目中。
Process of identifier assignment:
标识符分配过程：
Identifiers are assigned in the following manner. Projects are assigned a Model Identifier by the NAMSA organization. Projects then generate identifiers using the processes outlined in ASD S1000D. The codes are prefixed with the encoding identifier and possibly postfixed by the extension status identifiers.
标识符按以下方式分配。NAMSA组织为项目分配了一个模型标识符。然后，项目使用ASD S1000D中概述的过程生成标识符。代码以编码标识符作为前缀，可能由扩展状态标识符作为后缀。
Process for identifier resolution:
标识符解析过程：
The project identified by the Model Identifier is responsible for providing a method of resource resolution. A suggested method of resolution is outlined in ASD S1000D.
由模型标识符标识的项目负责提供资源解析方法。ASD S1000D中概述了建议的分辨率方法。
Rules for Lexical Equivalence:
词汇对等规则：
All generated identifiers are to be considered case-insensitive.
所有生成的标识符应视为不区分大小写。
Conformance with URN syntax:
符合URN语法：
No special considerations.
没有特别考虑。
Validation mechanism:
验证机制：
Identifiers must conform to ASD S1000D.
标识符必须符合ASD S1000D的要求。
Scope:
范围：
Global.
全球的

There are no additional security considerations other than those normally associated with the use and resolution of URNs in general.
除了通常与使用和解决骨灰盒相关的安全注意事项外，没有其他安全注意事项。
Resources will be named and maintained in accordance with the processes described in this document, in addition to the processes described in S1000D. Any organization or individual can utilize the specification to create resources described by S1000D. Resolution and/or use of created resources is unrestricted by the specification in order to promote widespread adoption of open ASD standards, although organizations creating resources may control them as they see fit.
除S1000D中描述的过程外，资源将根据本文件中描述的过程进行命名和维护。任何组织或个人均可利用本规范创建S1000D所述的资源。为促进开放式ASD标准的广泛采用，本规范不限制创建资源的解析和/或使用，尽管创建资源的组织可能会在其认为合适的情况下对其进行控制。
