Internet Society Requests For Comment (RFCs)
This document discusses how national bibliography numbers (persistent and unique identifiers assigned by the national libraries) can be supported within the URN (Uniform Resource Names) framework and the syntax for URNs defined in RFC 2141. Much of the discussion is based on the ideas expressed in RFC 2288. This memo provides information for the Internet community.

This document discusses how national bibliography numbers (persistent and unique identifiers assigned by the national libraries) can be supported within the URN (Uniform Resource Names) framework and the syntax for URNs defined in RFC 2141. Much of the discussion is based on the ideas expressed in RFC 2288.
As part of the validation process for the development of URNs the IETF 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] investigated the feasibility of using three identifiers (ISBN, ISSN and SICI) as URNs.
This document will analyse the usage of national bibliography numbers (NBNs) as URNs. The need to extend analysis to new identifier systems was briefly discussed in RFC 2288 as well, with the following summary: "The issues involved in supporting those additional identifiers are anticipated to be broadly similar to those involved in supporting ISBNs, ISSNs, and SICIs".

RFC 3188 Using National Bibliography Numbers as URNs October 2001
A registration request for acquiring a Namespace Identifier (NID) "NBN" for national bibliography numbers has been written by the National Library of Finland on the request of the Conference of Directors of National Libraries (CDNL) and the Conference of the European National Librarians (CENL). Chapter 5 contains a URN namespace registration request modeled according to the template in RFC 2611.
The document at hand is part of a global co-operation of the national libraries to foster identification of electronic documents in general and utilisation of URNs in particular. Some national libraries, including the national libraries of Finland, Norway and Sweden, are already assigning NBN-based URNs for electronic resources.
We have used the URN Namespace Identifier "NBN" for the national bibliographic numbers in examples below.
2. Identification vs. Resolution
As a rule the national bibliography numbers identify finite, manageably-sized objects, but these objects may still be large enough that resolution to a hierarchical system is appropriate.
The materials identified by a national bibliography number may exist only in printed or other physical form, not electronically. The best ...
