URN Namespace for MEF Documents
MEF文档的URN命名空间
Abstract
摘要
This document describes the Namespace Identifier (NID) "mef" for Uniform Resource Names (URNs) used to identify resources published by MEF Forum (https://www.mef.net). MEF specifies and manages resources that utilize this URN identification model. Management activities for these and other resources types are handled by the manager of the MEF Assigned Names and Numbers (MANN) registry.
本文档描述了统一资源名称（URN）的名称空间标识符（NID）“mef”，用于标识mef论坛发布的资源(https://www.mef.net). MEF指定并管理使用此URN标识模型的资源。这些和其他资源类型的管理活动由MEF分配名称和编号（MANN）注册中心的经理处理。

The MEF Forum (MEF) is a nonprofit international industry standards organization dedicated to the worldwide adoption of Carrier Ethernet (CE) networks and services. The forum creates specifications in the areas of Services, Architecture, and Operations and Management.
MEF论坛（MEF）是一个非营利的国际行业标准组织，致力于在全球范围内采用载波以太网（CE）网络和服务。该论坛创建了服务、体系结构、运营和管理领域的规范。
As part of these specifications efforts, there is a need to identify identifiers in a managed namespace that are unique and persistent. To ensure that this namespace's uniqueness is absolute, a registration of a specific URN Syntax [RFC2141] Namespace Identifier (NID) for use by MEF is being specified in this document.
作为这些规范工作的一部分，需要在托管命名空间中标识唯一且持久的标识符。为确保此命名空间的唯一性是绝对的，本文档中指定了MEF使用的特定URN语法[RFC2141]命名空间标识符（NID）的注册。

Declaration of syntactic structure:
句法结构声明：
The syntax of namespace-specific strings for the "mef" namespace is <NSS> in RFC 2141.
RFC 2141中“mef”命名空间的命名空间特定字符串的语法为<NSS>。
Relevant ancillary documentation:
相关辅助文件：
MEF publishes information regarding the registered resources in the MEF Assigned Names and Numbers (MANN) registry (https://www.mef.net/MANN).
MEF在MEF分配名称和编号（MANN）注册表中发布有关已注册资源的信息(https://www.mef.net/MANN).
Identifier uniqueness considerations:
标识符唯一性注意事项：
MEF will manage resource classes using the "mef" NID and will be the authority for managing resources and associated subsequent strings. MEF is expected to guarantee the uniqueness of the strings themselves, or it may permit secondary responsibility for certain defined resources.
MEF将使用“MEF”NID管理资源类，并将是管理资源和相关后续字符串的权限。MEF应该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。
MEF could allow for 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 different resources and specific strings.
MEF可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不同的资源和特定字符串使用相同的值。
Identifier persistence considerations:
标识符持久性注意事项：
MEF will update the MEF Assigned Names and Numbers (MANN) registry to document the registered resources that will use the "mef" NID.
MEF将更新MEF分配名称和编号（MANN）注册表，以记录将使用“MEF”NID的注册资源。
Process of identifier assignment:
标识符分配过程：
Assignment of a URN from the MEF namespace will be documented as part of the MEF Assigned Names and Numbers (MANN) registry.
MEF名称空间的URN分配将作为MEF分配名称和编号（MANN）注册表的一部分进行记录。
Process of identifier resolution:
标识符解析过程：
The namespace is not listed with a Resolution Discovery System (RDS). Therefore, this process is not relevant.
命名空间未与解析发现系统（RDS）一起列出。因此，这一过程并不相关。
Rules for Lexical Equivalence:
词汇对等规则：
The entire URN is case-insensitive.
整个URN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：
None specified. URN assignment will be handled by procedures implemented in support of MEF activities.
没有具体说明。URN分配将由支持MEF活动的程序执行。
Scope:
范围：
Global
全球的
The following are examples of URNs that MEF is looking to assign:
以下是MEF希望指定的URN示例：
urn:mef:yang:mef-services
urn:mef:yang:mef-services
urn:mef:yang:mef-interfaces
urn:mef:yang:mef-interfaces
There are no security considerations other than those normally associated with the use and resolution of URNs in general, which are described in "Function Requirements for Uniform Resource Names" [RFC1737] and "URN Syntax" [RFC2141].
除了通常与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，如“统一资源名称的功能要求”[RFC1737]和“URN语法”[RFC2141]中所述。
Per this document, IANA has added a new entry ("mef") in the "Uniform Resource Names (URN) Namespaces" registry available from the IANA site (https://www.iana.org).
根据本文档，IANA在“统一资源名称（URN）命名空间”注册表中添加了一个新条目（“mef”），该注册表可从IANA站点获得(https://www.iana.org).
