Abstract

摘要

This document describes a URN (Uniform Resource Name) namespace for identifying NewsML NewsItems. A NewsItem is an information resource that is expressible as a NewsML element within a NewsML document conforming to the NewsML Document Type Declaration (DTD) as defined by the International Press Telecommunications Council (IPTC).

本文档描述了用于标识NewsML新闻项的URN（统一资源名）命名空间。NewsItem是一种信息资源，可表示为符合国际新闻电信委员会（IPTC）定义的NewsML文档类型声明（DTD）的NewsML文档中的NewsML元素。

1. Introduction

1. 介绍

NewsML is an XML format for packaging multimedia news resources. It has been created under the auspices of the International Press Telecommunications Council (IPTC), and version 1.0 was approved by the IPTC on 6 October 2000.

NewsML是一种用于打包多媒体新闻资源的XML格式。它是在国际新闻电信理事会（IPTC）的主持下创建的，IPTC于2000年10月6日批准了1.0版。

The same logical NewsItem may exist in multiple physical locations. The NewsML specification allows NewsItems to have multiple URLs, but only a single URN. It is the latter which then uniquely names the resource.

同一逻辑新闻项可能存在于多个物理位置。NewsML规范允许新闻项有多个URL，但只有一个URN。然后由后者对资源进行唯一命名。

This namespace specification is for a formal namespace.

此名称空间规范适用于正式名称空间。

Declaration of structure:

结构声明：

The identifier has the following ABNF[6] specification:

标识符具有以下ABNF[6]规范：

      NSS = ProviderId ":" DateId ":" NewsItemId ":" RevisionId Update
      ProviderId = string
      DateId = date
      NewsItemId = string
      RevisionId = posint
      Update = 0*1( "A" / "U" )
      date = century year month day
      century = ( "0" posdig ) / ( posdig DIGIT )
      year = 1*2DIGIT
      month = ( 0 posdig ) / ( "1" ( "0" "1" "2" ) )
      day = ( 0 posdig ) / ( ( "1" / "2" ) DIGIT ) / "30" / "31"
      string = 1*char
      char = ALPHA / DIGIT / symbol / escape
      symbol = "(" / ")" / "+" / "," / "-" / "." / "=" / "@" / ";" /
        "$" / "_" / "!" / "*" / "'"
      escape = "%" HEXDIG HEXDIG
      posint = posdig *DIGIT
      posdig = "1" / "2" / "3" / "4" / "5" / "6" / "7" / "8" / "9"

      NSS = ProviderId ":" DateId ":" NewsItemId ":" RevisionId Update
      ProviderId = string
      DateId = date
      NewsItemId = string
      RevisionId = posint
      Update = 0*1( "A" / "U" )
      date = century year month day
      century = ( "0" posdig ) / ( posdig DIGIT )
      year = 1*2DIGIT
      month = ( 0 posdig ) / ( "1" ( "0" "1" "2" ) )
      day = ( 0 posdig ) / ( ( "1" / "2" ) DIGIT ) / "30" / "31"
      string = 1*char
      char = ALPHA / DIGIT / symbol / escape
      symbol = "(" / ")" / "+" / "," / "-" / "." / "=" / "@" / ";" /
        "$" / "_" / "!" / "*" / "'"
      escape = "%" HEXDIG HEXDIG
      posint = posdig *DIGIT
      posdig = "1" / "2" / "3" / "4" / "5" / "6" / "7" / "8" / "9"

The ProviderId must be an Internet domain name, and must be owned by the organisation creating the NewsML resource and allocating the URN to it, at the date identified by the DateId. DateId is a date in ISO 8601 Basic Format (CCYYMMDD), and must correspond to a date at which the organisation allocating the URN owned the domain name specified in the ProviderId. The NewsItemId must be unique among all NewsItems emanating from the same provider and having the same DateId.

ProviderId必须是Internet域名，并且必须在DateId标识的日期由创建NewsML资源并向其分配URN的组织拥有。DateId是ISO 8601基本格式（CCYYMMDD）的日期，必须与分配URN的组织拥有ProviderId中指定的域名的日期相对应。NewsItemId在来自同一提供者且具有相同DateId的所有新闻项中必须是唯一的。

RevisionId is a positive integer indicating which revision of a given NewsItem this is. Any positive integer may be used, but it must always be the case that of two instances of a NewsItem that have the same ProviderId, DateId and NewsItemId, the one whose RevisionId has the larger value must be the more recent revision. A RevisionId of 0 is not permitted. If the NewsItem contains an "Update" element or elements, then Update must be set to "U". If the NewsItem consists only of a replacement set of NewsManagement data, then Update must be set to "A". If neither of these is the case, then Update must be suppressed.

RevisionId是一个正整数，指示给定新闻项的版本。可以使用任何正整数，但必须始终使用具有相同ProviderId、DateId和NewsItemId的新闻项的两个实例，其RevisionId值较大的实例必须是较新的版本。不允许修改ID为0。如果新闻项包含一个或多个“更新”元素，则更新必须设置为“U”。如果新闻项仅由一组替换的新闻管理数据组成，则更新必须设置为“a”。如果两者都不是，则必须抑制更新。
