From OASIS news:
URN Namespace for National Emergency Number Association (NENA)
Brian Rosen (ed), IETF Internet Draft
The Internet Engineering Steering Group (IESG) has issued a Last Call
review for the specification "Universal Resource Name (URN) Namespace
for National Emergency Number Association (NENA)". The submitter asks
for consideration of this document as an IETF Informational RFC. The
IESG plans to make a decision in the next few weeks, and solicits final
comments on this action; please send substantive comments to the IETF
at the mailing lists by 2010-08-30. The document "describes the
Namespace Identifier (NID) 'nena' for Uniform Resource Names (URN)
resources published by National Emergency Number Association (NENA).
NENA defines and manages resources that utilize this URN name model.
Management activities for these and other resource types are provided
by the National Emergency Number Association (NENA) Registry System
(NRS)."
From the Introduction: "NENA is the 'Voice of 9-1-1' in North America.
NENA's mission is to foster the technological advancement, availability
and implementation of a universal emergency telephone number system
(9-1-1). In carrying out its mission, NENA promotes research, planning,
training and education. The protection of human life, the preservation
of property, and the maintenance of general community security are
among NENA's objectives. NENA serves as a link in the delivery of
emergency services. 9-1-1 has, throughout its evolution, become
recognized as an asset of the North American public. NENA is currently
in the process of setting standards, processes and procedures for the
use of an IP-based Emergency Services IP Network (ESInet) for all public
safety entities in North America. This activity is supported by a
membership composed of private and public sector entities that have
an interest in 9-1-1 and public safety. This effort, dubbed 'Next
Generation 9-1-1' (NG9-1-1) is based in large part on IETF standards
for interactive media session establishment and emergency calling.
Some of the solutions being developed by NENA need XML namespaces that
are managed so that they are unique and persistent. To assure that the
uniqueness is absolute, the registration of a specific Uniform Resource
Name Namespace ID (NID) for use by NENA was deemed appropriate...
NENA maintains a naming authority, the National Emergency Number
Association (NENA) Registration System (NRS) that will manage the
assignment of 'NENAclass' and the specific registration values assigned
for each class. Other NENA Standards documents will define the
'ClassSpecificStrings' for a given 'NENAclass'. The National Emergency
Number Association Registration System (NRS) provides information on
the registered resources and the registrations for each... The NRS will
manage resources using the 'nena' NID and will be the authority for
managing the resources and subsequent strings associated. The NRS shall
ensure the uniqueness of all nena URNs by checking such names against
the list of existing namespace names, as documented in NENA 70-001..."
