CableLabs的统一资源名称（URN）命名空间
Abstract
摘要
This document describes the Namespace Identifier (NID) 'cablelabs' for Uniform Resource Names (URNs) used to identify resources published by Cable Television Laboratories, Inc. (CableLabs). CableLabs specifies and manages resources that utilize this URN identification model. Management activities for these and other resource types are handled by the manager of the CableLabs' Assigned Names and Numbers registry.

CableLabs is a non-profit research and development consortium that is dedicated to pursuing new cable telecommunications technologies and to helping its cable operator members integrate those technical advancements into their business objectives. Within CableLabs, specification activities are organized into projects such as DOCSIS(R), PacketCable(TM), and OpenCable(TM), and technical work is conducted within focus teams. Product vendors, manufacturers, and cable operator members are invited to join the focus teams that create technical specifications.
CableLabs是一家非营利性研发财团，致力于开发新的有线电信技术，并帮助其有线运营商成员将这些技术进步融入其业务目标。在CableLabs中，规范活动被组织到DOCSIS（R）、PacketCable（TM）和OpenCable（TM）等项目中，技术工作在焦点团队中进行。邀请产品供应商、制造商和电缆运营商成员加入创建技术规范的重点团队。
Occasionally, CableLabs specification efforts require identifiers in a managed namespace so that they are unique and persistent. To ensure that the uniqueness is absolute, the registration of a specific Uniform Resource Name (URN) [RFC2141] Namespace Identifier
有时，CableLabs规范工作需要托管命名空间中的标识符，以便它们是唯一和持久的。为了确保唯一性是绝对的，需要注册特定的统一资源名（URN）[RFC2141]命名空间标识符
(NID) for use by CableLabs is being specified in this document, in full conformance with the NID registration process specified in [RFC3406].
（NID）供CableLabs使用，完全符合[RFC3406]中规定的NID注册流程。
Namespace ID: cablelabs
命名空间ID:cablelabs
Registration information: registration version number: 1 registration date: 2011-04-18
注册信息：注册版本号：1注册日期：2011-04-18
Declared registrant of the namespace: Registering organization Name: Cable Television Laboratories, Inc. Address: 858 Coal Creek Circle, Louisville, CO 80027, USA Designated contact Role: Manager, Standards Email: ietf_standards@cablelabs.com
名称空间的声明注册人：注册机构名称：有线电视实验室有限公司地址：858 Coal Creek Circle，Louisville，CO 80027，USA指定联系人角色：经理，标准电子邮件：ietf_standards@cablelabs.com
Declaration of syntactic structure: The Namespace Specific String (NSS) of all URNs that use the "cablelabs" NID will have the following structure:
语法结构声明：使用“cablelabs”NID的所有URN的命名空间特定字符串（NSS）将具有以下结构：
{CLclass}:{CLClassSpecificString}
{CLclass}:{CLClassSpecificString}
The "CLclass" is a US-ASCII string that conforms to the URN syntax requirements specified in [RFC2141] and defines a specific class of resource type. Each class will have a specific labeling scheme that is covered by "CLClassSpecificString", which also conforms to the naming requirements of [RFC2141].
“CLclass”是一个US-ASCII字符串，符合[RFC2141]中规定的URN语法要求，并定义了资源类型的特定类。每个类都有一个特定的标签方案，该方案包含在“CLClassSpecificString”中，该方案也符合[RFC2141]的命名要求。
CableLabs maintains the CableLabs' Assigned Names and Numbers [CANN] specification that will contain the assignment of CableLabs' resource classes and the specific registration values assigned for each resource class.
CableLabs维护CableLabs的分配名称和编号[CANN]规范，该规范将包含CableLabs资源类的分配以及为每个资源类分配的特定注册值。
Relevant ancillary documentation: CableLabs publishes information regarding the registered resources in the CableLabs' Assigned Names and Numbers specification ([CANN]).
相关辅助文档：CableLabs在CableLabs的指定名称和编号规范（[CANN]）中发布有关注册资源的信息。
Identifier uniqueness considerations: CableLabs will manage resource classes using the "cablelabs" NID and will be the authority for managing resources and associated subsequent strings. CableLabs is expected to guarantee the uniqueness of the strings themselves, or it may permit secondary responsibility for certain defined resources.
标识符唯一性注意事项：CableLabs将使用“CableLabs”NID管理资源类，并将成为管理资源和相关后续字符串的权限。CableLabs应保证字符串本身的唯一性，或者允许对某些定义的资源承担次要责任。
CableLabs could allow the use of experimental type values for testing purposes only. Note that using experimental types may create collisions as multiple users may use the same values for resources and specific strings.
CableLabs允许仅出于测试目的使用实验类型值。请注意，使用实验类型可能会产生冲突，因为多个用户可能会对资源和特定字符串使用相同的值。
Identifier persistence considerations: CableLabs will update the CableLabs' Assigned Names and Numbers specification ([CANN]) to document the registered resources that use the "cablelabs" NID.
标识符持久性注意事项：CableLabs将更新CableLabs的分配名称和编号规范（[CANN]），以记录使用“CableLabs”NID的注册资源。
Process of identifier assignment: CableLabs will provide procedures for registration of each type of resource that it maintains. Each such resource may have three types of registration activities:
标识符分配过程：CableLabs将提供其维护的每种类型资源的注册程序。每个此类资源可能有三种类型的注册活动：
1. Registered values associated with CableLabs documents or services 2. Registration of values or sub-trees to other entities 3. Name models for use in experimental purposes
1. 与CableLabs文档或服务相关的注册值2。将值或子树注册到其他实体3。命名用于实验目的的模型
Process for identifier resolution: The namespace is not listed with a resolution discovery system; this is not applicable for this URN registration.
标识符解析过程：命名空间未与解析发现系统一起列出；这不适用于此URN注册。
Rules for lexical equivalence: No special considerations; the rules for lexical equivalence of [RFC2141] apply.
词汇对等规则：无特殊考虑；[RFC2141]的词汇对等规则适用。
Conformance with URN syntax: No special considerations.
与URN语法的一致性：无需特别考虑。
Validation mechanism: None specified. URN assignment will be handled by procedures implemented in support of CableLabs activities.
验证机制：未指定。URN分配将由支持CableLabs活动的程序执行。
Scope: Global
范围：全球
The following example represents a hypothetical URN that could be assigned by CableLabs.
以下示例表示CableLabs可以分配的假设URN。
urn:cablelabs:packetcable-example:ue:rst-sample
urn:cablelabs:packetcable-example:ue:rst-sample
This example defines the URN to be used for User Equipment (UE) conforming to the sample Residential SIP Telephony (RST) application specified within CableLabs' PacketCable RST specification suite.
此示例定义了用户设备（UE）所使用的URN，该用户设备（UE）符合CableLabs的PacketCable RST规范套件中指定的示例住宅SIP电话（RST）应用程序。
CableLabs develops specifications that may require the use of data models. URN Namespaces are key constructs to manage the definitions of those data models reliably with persistence and uniqueness.
CableLabs制定了可能需要使用数据模型的规范。URN名称空间是可靠地管理这些数据模型定义的关键结构，具有持久性和唯一性。
The use of URNs should also help specification authors to maintain different versions of URNs and dependencies between URNs across different versions of CableLabs specifications if they so wish.
URN的使用还应有助于规范作者维护URN的不同版本以及跨CableLabs规范的不同版本的URN之间的依赖关系（如果他们愿意的话）。
Participants involved in the development and usage of CableLabs specifications and cable industry deployments will benefit from the publication of this namespace by providing consistent and reliable names for the XML namespaces, schema locations, and similar identifiers of physical data models published within CableLabs specifications.
参与CableLabs规范和电缆行业部署的开发和使用的参与者将受益于该名称空间的发布，他们将为在CableLabs规范中发布的XML名称空间、模式位置和物理数据模型的类似标识符提供一致和可靠的名称。
The CableLabs specifications are publicly available and are licensed to manufacturers on a nondiscriminatory basis. CableLabs will maintain the allocation of resources for the "cablelabs" NID within the following specification: "CableLabs' Assigned Names and Numbers" [CANN], which will be publicly available for viewing. CableLabs will also maintain the corresponding specifications where the registered resources are referenced or used.
CableLabs规范可公开获取，并以非歧视的方式许可给制造商。CableLabs将在以下规范中维护“CableLabs”NID的资源分配：“CableLabs分配的名称和编号”[CANN]，该规范将公开供查看。CableLabs还将维护引用或使用注册资源的相应规范。
This document adds a new entry ("cablelabs") in the urn-namespaces registry. This is the defining document. The entry can be found in the "Uniform Resource Names (URN) Namespaces" registry available from the IANA site (http://www.iana.org) and any associated mirrors.
本文档在urn名称空间注册表中添加了一个新条目（“cablelabs”）。这是定义文档。该条目可以在IANA站点提供的“统一资源名称（URN）命名空间”注册表中找到(http://www.iana.org)以及任何相关的镜子。
There are no additional security considerations other than those normally associated with the use and resolution of URNs in general, which are described in [RFC1737], [RFC2141], and [RFC3406].
除了[RFC1737]、[RFC2141]和[RFC3406]中描述的通常与URN的使用和解析相关的安全注意事项外，没有其他安全注意事项。
