Abstract
This document describes a Uniform Resource Name (URN) namespace for
the Digital Video Broadcasting Project (DVB) for naming persistent
resources defined within DVB standards. Example resources include
technical documents and specifications, eXtensible Markup Language
(XML) Schemas, classification schemes, XML Document Type Definitions
(DTDs), namespaces, style sheets, media assets, and other types of
resources produced or managed by DVB.

1. Introduction
The Digital Video Broadcasting Project (DVB) is an industry-led
consortium of over 270 broadcasters, manufacturers, network
operators, software developers, regulatory bodies and others in over
35 countries committed to designing global standards for the global
delivery of digital television and data services. Services using DVB
standards are available on every continent with a total of more than
100 million DVB receivers already deployed.
DVB would like to assign unique, permanent, location-independent
names based on URNs for some resources it produces or manages.
This namespace specification is for a formal namespace.
2. Specification Template
Namespace ID:
"dvb"
Registration Information:
Version: 1
Date: 2007-02-28
Declared registrant of the namespace:
Name: Peter MacAvock

Affiliation: DVB Digital Video Broadcasting

Internet Draft DVB URN May 25, 2007
Declaration of structure:
URNs assigned by DVB will have the following hierarchical
structure based on the organizational structure of the DVB
standards:
urn:dvb:{assigned US-ASCII string}
where "{assigned US-ASCII string}" is a US-ASCII string that
conforms to URN Syntax requirements ([RFC2141]).
The individual URNs will be assigned by DVB through the process of
development of DVB standards.
Relevant ancillary documentation:
None
Identifier uniqueness considerations:
DVB will establish unique identifiers as appropriate.
Uniqueness is guaranteed as long as the assigned string is never
reassigned.
Identifier persistence considerations:
DVB is committed to maintaining the accessibility and persistence
of all resources that are officially assigned URNs by the
organization.
Process of identifier assignment:
Assignment is limited to the owner and those authorities that are
specifically designated by the owner. DVB may designate portions
of its namespace for assignment by other parties.
Process of identifier resolution:
The owner will develop and maintain "URN catalogues" that map all
assigned URNs to Uniform Resource Locators (URLs) specifically to
enable Web-based resolution of named resources. In the future an
interactive online resolution system may be developed to automate
this process.
The owner will authorize additional resolution services as
appropriate.

Internet Draft DVB URN May 25, 2007
Rules for Lexical Equivalence:
The "assigned US-ASCII string" is case-insensitive.
Conformance with URN Syntax:
No special considerations.
Validation mechanism:
None specified. The owner will develop and maintain URN
catalogues. The presence of a URN in a catalogue indicates that
it is valid.
Scope:
Global
3. Examples
The following examples are not guaranteed to be real. They are
presented for pedagogical reasons only.
urn:dvb:ipdc:esg:2005
urn:dvb:cs:ZappingTypeCS:2001
4. Namespace Considerations
URN assignment procedures:
The individual URNs shall be assigned through the process of
development of DVB standards by the Digital Video Broadcasting
Project (DVB).
URN resolution/delegation:
The resolution and delegation shall be determined through the
process of development of DVB standards by the Digital Video
Broadcasting Project (DVB).
Type of resources to be identified:
Types of resources to be identified include XML schema definition
files, classification schemes and identification systems.
Type of services to be supported:
Types of services supported include controlled term lookup in

classification schemes, resolution of ids in identification
systems.
5. Community Considerations
Open assignment and use of identifiers within the namespace:
With on-going development of DVB standards, DVB will establish
requirements for assignment and use of identifiers within the DVB
namespace.
Open operation of resolution servers for the namespace (server):
With on-going development of DVB standards, DVB will establish
requirements and seek candidates for operating resolution servers
as appropriate.
Creation of software that can meaningfully resolve and access
services for the namespace (client):
With on-going development of DVB standards, DVB members will
develop software implementations of its standards.
6. Security Considerations
There are no additional security considerations other than those
normally associated with the use and resolution of URNs in general.
7. IANA Considerations
The IANA has registered formal URN namespace XXX, to DVB within the
IANA registry of URN NIDs.
