Abstract
摘要
This document describes a URN (Uniform Resource Name) namespace that is engineered by the Organization for the Advancement of Structured Information Standards (OASIS) for naming persistent resources stored in the XML.org repository (such as XML (Extensible Markup Language) Document Type Definitions, XML Schemas, Namespaces, Stylesheets, and other documents).
本文档描述了由结构化信息标准促进组织（OASIS）设计的URN（统一资源名称）命名空间，用于命名存储在XML.org存储库中的持久资源（如XML（可扩展标记语言））文档类型定义、XML模式、名称空间、样式表和其他文档）。
The XML.org Registry is provided by XML.org as a public service where XML schemas, DTDs, stylesheets, and other documents can be shared. Documents are submitted to a repository then retrieved by others who may want to use them. These documents require unique identifiers.

Motivated by these observations, XML.org would like to assign URNs to some resources in order to retain unique, permanent location-independent names for them.
出于这些观察的动机，XML.org希望将URN分配给一些资源，以便为它们保留唯一的、永久的、独立于位置的名称。
This namespace specification is for a formal namespace.
此名称空间规范适用于正式名称空间。
Namespace ID:

Declaration of structure:
结构声明：
The Namespace Specific String (NSS) of all URNs assigned by XML.org will have the following hierarchical structure:
XML.org分配的所有URN的命名空间特定字符串（NSS）将具有以下层次结构：
There is one branch at the top of the hierarchy: "objects".
在层次结构的顶部有一个分支：“对象”。
The Objects Hierarchy
对象层次结构
The general structure of the NSS in the names hierarchy has the form:
名称层次结构中NSS的一般结构具有以下形式：
urn:xmlorg:objects:{type}{:subtype}?:{object-id}
urn:xmlorg:objects:{type}{:subtype}?:{object-id}
where "type" identifies the document type (document, schema, stylesheet, entity, xmlns, etc.), the optional "subtype" provides additional information about the document type (for example, stylesheet or schema language), and "object-id" is a unique identifier for the document.
如果“type”标识文档类型（文档、模式、样式表、实体、xmlns等），则可选的“subtype”提供有关文档类型的附加信息（例如，样式表或模式语言），“object id”是文档的唯一标识符。
The Director of Technical Operations at OASIS assigns document types, subtypes, and all unique identifiers.
OASIS技术运营总监分配文档类型、子类型和所有唯一标识符。
Relevant ancillary documentation:
相关辅助文件：
None
没有一个
Identifier uniqueness considerations:
标识符唯一性注意事项：
Identifier uniqueness will be enforced by the Director of Technical Operations who assigns unique identifiers to all documents identified by URN.
标识符唯一性将由技术运营总监执行，该总监为URN识别的所有文件分配唯一标识符。
Identifier persistence considerations:
标识符持久性注意事项：
OASIS is committed to maintaining the accessibility and persistence of all the resources that are assigned URNs.
OASIS致力于维护分配给URN的所有资源的可访问性和持久性。
Process of identifier assignment:
标识符分配过程：
Assignment is limited to the owner and those authorities that are specifically designated by the owner. OASIS may assign portions of its namespace for assignment by other parties.
转让仅限于业主和业主特别指定的机构。OASIS可以将其命名空间的一部分分配给其他方。
Process of identifier resolution:
标识符解析过程：
The owner will distribute catalogs (OASIS TR9401 Catalogs) that map the assigned URNs to resource identifiers (e.g., URLs). A more interactive, online resolution system will also be deployed in the near future.
所有者将分发将分配的URN映射到资源标识符（例如URL）的目录（OASIS TR9401目录）。在不久的将来，还将部署一个更具互动性的在线解决系统。
The owner will authorize additional resolution services as appropriate.
业主将酌情授权额外的解决服务。
Rules for Lexical Equivalence:
词汇对等规则：
URNs are lexically equivalent if they are lexically identical.
如果URN在词汇上相同，则它们在词汇上是等价的。
Conformance with URN Syntax:
符合URN语法：
No special considerations.
没有特别考虑。
Validation mechanism:
验证机制：
None specified. The owner will publish OASIS TR9401 Catalogs. The presence of a URN in a catalog indicates that it is valid.
没有具体说明。所有者将发布OASIS TR9401目录。目录中存在URN表示它是有效的。
Scope:
范围：
Global
全球的
The following examples are not guaranteed to be real. They are listed for pedagogical reasons only.
以下示例不能保证是真实的。它们仅出于教学原因列出。
urn:xmlorg:objects:schema:xmlschema:xcatalog
urn:xmlorg:objects:dtd:xml:docbook:v4.1.2
urn:xmlorg:objects:schema:xmlschema:xcatalog
urn:xmlorg:objects:dtd:xml:docbook:v4.1.2
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。
