Abstract

This document discusses how International Standard Book Numbers (ISBN) can be supported within the URN (Uniform Resource Names) framework and the syntax for URNs defined in RFC 2141. Much of the discussion below is based on the ideas expressed in RFC 2288.

Abstract

   This document discusses how International Standard Book Numbers

   (ISBN) can be supported within the URN (Uniform Resource Names)

   framework and the syntax for URNs defined in RFC 2141.  Much of the

   discussion below is based on the ideas expressed in RFC 2288.

1. Introduction

   As part of the validation process for the development of URNs, the

   IETF URN working group agreed that it is important to demonstrate

   that the current URN syntax proposal can accommodate existing

   identifiers from well established namespaces.  One such

   infrastructure for assigning and managing names comes from the

   bibliographic community.  Bibliographic identifiers function as names

   for objects that exist both in print and, increasingly, in electronic

   formats.  RFC 2288 [Lynch, et al.] investigated the feasibility of

   using three identifiers (ISBN, ISSN and SICI) as URNs.  This document

   will analyse the usage of ISBNs as URNs in more detail than RFC 2288.

   A registration request for acquiring Namespace Identifier (NID)

   "ISBN" for ISBNs is included in chapter 5.

RFC 3187                  Using ISBNs as URNs               October 2001

   The document at hand is part of a global joint venture of the

   national libraries to foster identification of electronic documents

   in general and utilisation of URNs in particular.  The document was

   written as a co-operative project between the Helsinki University

   Library and The International ISBN Agency.

   We have used the URN Namespace Identifier "ISBN" for ISBNs in

   examples below.

2. Identification vs. Resolution

   As a rule the ISBNs identify finite, manageably-sized objects, but

   these objects may still be large enough that resolution into a

   hierarchical system is appropriate.

   The materials identified by an ISBN may exist only in printed or

   other physical form, not electronically.  The best that a resolver

   will be able to offer in this case is bibliographic data from a

   national bibliography database, including information about where the

   physical resource is stored in the national library's holdings.

3. International Standard Book Numbers

3.1 Overview

   RFC 2288 [Lynch] describes the ISBN system in the following way:

      An International Standard Book Number (ISBN) identifies an edition

      of a monographic work.  The ISBN is defined by the standard

      NISO/ANSI/ISO 2108:1992 [ISO1]

      Basically, an ISBN is a ten-digit number (actually, the last digit

      can be the letter "X" as well, as described below) which is

      divided into four variable length parts usually separated by

      hyp...
