This document describes a Uniform Resource Name (URN) Namespace
Identification (NID)convention as prescribed by the World Wide Web
Consortium (W3C) for identifying, naming, assigning, and managing
persistent resources and XML artefacts for the New Zealand
The New Zealand Government has already adopted XML as its primary
means of storing and exchanging data. The New Zealand Government
publishes documents, schemas, and other government artefacts.
The New Zealand Government now wishes to define a namespace
convention and structure for its agencies by creating and managing
globally unique, persistent, location-independent identifiers for
their schema resources and XML artefacts.
This is a natural extension of the development of the Dublin Core
based New Zealand Government metadata standard (New Zealand
Government Locator Service, or NZGLS) used by government agencies to
create metadata and made operational to the public through an all-
The New Zealand Government wishes to provide guidance on namespaces
to its agencies so that they use a portion of the adopted namespace
to minimise the risk of their creating different (and potentially
conflicting) namespace structures. This issue potentially extends to
Hendrikx & Wallis Informational [Page 1]RFC 4350 URN for New Zealand Government February 2006
data exchange beyond government into the private sector of New
Zealand, thus placing the government under an obligation to provide
guidance in the assignment and management of additional namespaces.
The New Zealand Government wishes to register the country NID, NZL,
with the Name Specific String (NSS) split into two parts; the first
part being a specific sub-type <nz-specifier> and the second part as
a <nz-specifier defined string>.
As part of the URN structure, the New Zealand Government wishes to
define and subsequently manage the "govt" specifier. It will also
assign additional specifiers requested by other New Zealand
organisations in accordance with the rules and processes proposed
The New Zealand Government hoped to make use of the two-letter
Namespace Identifier (NID) combination for its ubiquitous country
code, NZ. But since there is as yet no process to register these
(see RFC 3406 ) the government has opted to request its well-known
alternative three-letter country code (see ISO 3166 ).
This namespace specification requests a formal namespace (see  for
more information about formal namespaces).
Please note that this paper includes a discussion on the use of
diacritic marks, in particular, Maori macrons. Maori is an official
language of New Zealand. In recognition of the established practice
of publishing RFCs for a global audience in ASCII text where
diacritic marks are unable to be recognised, the text has been
presented without macrons.

The identifier has a hierarchical structure as follows:
