Abstract

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).

1. Introduction

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.

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.

This namespace specification is for a formal namespace.

2. Specification Template

Namespace ID:

"newsml" requested.

Declaration of structure:

The identifier has the following ABNF[6] specification:

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 "," "."

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.

RFC 3085 URN Namespace for NewsML Resources March 2001

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 m...
