ISO/FDIS 15706-2

Information and documentation — International Standard Audiovisual Number (ISAN) — Part 2: Version identifier

ISO 15706-2:2007 establishes a voluntary system for the identification of versions of audiovisual works and other content derived from or closely related to an audiovisual work. It is based on the International Standard Audiovisual Number (ISAN) system defined in ISO 15706:2002. An ISAN combined with the version segment, as specified in ISO 15706-2:2007 constitutes an ISAN version identifier, is referred to as a V-ISAN. A V-ISAN is a registered, globally unique identifier for versions of an audiovisual work and related content. A V-ISAN identifies a specific version or other content related to an audiovisual work throughout its life. It is intended for use wherever precise and unique identification of a specific version or other content related to an audiovisual work would be desirable, such as in audiovisual production and distribution systems, broadcasting applications and electronic program guides. A V-ISAN identifies a specific version or other content related to an audiovisual work as the unique compound of its component elements (e.g. its artistic content, languages, editing and technical format) throughout its life and independent of any physical form in which that version or related content is distributed. The assignment of a V-ISAN to a version or other content related to an audiovisual work does not constitute evidence of the ownership of rights to either that version or related content or to the audiovisual work itself. ISO 15706-2:2007 specifies the basic systems and procedures to support the issuance and administration of V-ISANs.

Information et documentation — Numéro international normalisé d'oeuvre audiovisuelle (ISAN) — Partie 2: Identifiant de version

L'ISO 15706-2:2007 établit un système volontaire pour l'identification des versions d'oeuvres audiovisuelles et d'autres contenus dérivés ou intimement liés à une œuvre audiovisuelle (voir Annexe A). Elle est fondée sur le système de Numéro international normalisé des œuvres audiovisuelles (ISAN) défini dans l'ISO 15706. Un ISAN combiné avec le segment de version spécifié à l'Article 4 de la présente partie de l'ISO 15706 constitue un identifiant de version ISAN, ci-après désigné comme V-ISAN. Un V-ISAN est un identifiant enregistré de manière unique pour les versions d'une œuvre audiovisuelle ou un contenu qui lui est lié. Un V-ISAN identifie toute sa vie durant une version particulière d'une œuvre audiovisuelle ou d'un autre contenu qui lui est lié. Il a pour but d'être utilisé lors de l'identification précise et unique d'une version particulière ou lorsque le contenu de l'œuvre audiovisuelle est nécessaire, comme dans les systèmes de production et de diffusion audiovisuelles, dans les applications télévisées et dans les guides de programmes électroniques. Un V-ISAN identifie une version particulière d'une œuvre audiovisuelle ou d'un autre contenu qui lui est lié en tant que combinaison unique d'éléments qui la composent (par exemple son contenu artistique, ses langues, son montage et son format technique) toute sa vie durant et indépendamment de toute présentation matérielle dans laquelle cette version ou son contenu est diffusé. L'attribution d'un V-ISAN à une version d'une œuvre audiovisuelle ou à un contenu qui lui est lié ne sert pas à attester la propriété de droits attachés à cette version, à son contenu ou à l'œuvre audiovisuelle elle-même. L'ISO 15706-2:2007 spécifie les systèmes et les procédures de base qui assurent l'attribution et l'administration des V-ISANs.

ISO/FDIS 15706-2:2021(E)
Introduction

This document specifies the structure and basic criteria for the assignment of an identifier for versions

of audiovisual works and other content derived from or directly related to an audiovisual work. It

supplements the International Standard Audiovisual Number (ISAN) specified in ISO 15706-1 and

provides a mechanism for identifying versions and related content of audiovisual works that have been

registered in the International Standard Audiovisual Number (ISAN) system.

This document defines the version identifier component of the ISAN system, specifies the rules for

assignment of the ISAN version identifier, and the basic administration and registration procedures for

the ISAN version identification system.

The Registration Authority for ISO 15706 is the entity charged with oversight of the ISAN version

identification system. The Registration Authority maintains a database of all version registration

records (the register), issues new version identifiers upon proper request, and establishes the necessary

operational procedures to keep the system functioning properly.

The Registration Authority makes version registration and information retrieval services available

to those with a need to register new versions of audiovisual works or to obtain data about existing

registrations. The Registration Authority provides services to applicants for new ISAN version

identifiers, registrants of existing ISAN version identifiers, and other users.

The information contained in the version register is the minimum necessary to identify the versions to

which specific ISAN version identifiers apply. It is often desirable to make additional information about

the registered versions of audiovisual works available for access in a variety of ways. To enable the

association of such additional information with a version registration, mechanisms are provided to link

to entities providing access to that information. Those entities are called resolution service providers.

The version register itself is not intended for reverse lookups (where one requests the ISAN version

identifiers associated with specific metadata), but that does not preclude the Registration Authority

from providing such a service.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 15706-2:2021(E)
Information and documentation — International Standard
Audiovisual Number (ISAN) —
Part 2:
Version identifier
1 Scope

This document establishes a voluntary system for the identification of versions of audiovisual works

and other content derived from or closely related to an audiovisual work (see Annex A). It is based

on the International Standard Audiovisual Number (ISAN) system defined in ISO 15706-1. An ISAN

combined with the version segment specified in Clause 4 constitutes an ISAN version identifier,

hereinafter referred to as a V-ISAN. A V-ISAN is a registered, globally unique identifier for versions of an

audiovisual work and related content.

A V-ISAN identifies a specific version or other content related to an audiovisual work throughout its life.

It is intended for use wherever precise and unique identification of a specific version or other content

related to an audiovisual work would be desirable, such as in audiovisual production and distribution

systems, broadcasting applications, digital platforms and electronic program guides.

A V-ISAN identifies a specific version or other content related to an audiovisual work as the unique

compound of its component elements (e.g. its artistic content, languages, editing and technical format)

throughout its life and independent of any physical form in which that version or related content is

distributed.

The assignment of a V-ISAN to a version or other content related to an audiovisual work does not

constitute evidence of the ownership of rights to either that version or related content or to the

audiovisual work itself.

This document specifies the basic systems and procedures to support the issuance and administration

of V-ISANs.

administrative class of V-ISAN metadata (3.8) that uniquely identifies the V-ISAN registrant (3.10) and

provides other pertinent information required for administration of the V-ISAN system

4 Construction of the V-ISAN

4.1 A V-ISAN assigned to a version of an audiovisual work or to a related content entity shall

incorporate the ISAN for the audiovisual work from which that version or related content is derived.

4.2 A V-ISAN shall consist of a 64-bit ISAN that has been registered in accordance with ISO 15706-1,

followed by a 32-bit version segment. When represented using hexadecimal digits, this is equivalent to

an ISAN of 16 characters followed by a version segment of eight characters, using Arabic numerals 0 to

9 and letters A to F of the Latin alphabet. See Figure 1.
Figure 1 — Construction of a V-ISAN

4.3 As an aid to accurate transcription of V-ISAN in human-readable form (i.e. a form meant primarily

to be read or written by a person such as on labels, physical carriers, technical documentation, etc., in

contrast to a form primarily meant to be used by data processing equipment), a V-ISAN shall be preceded

by the letters ISAN and include the check characters for both the ISAN segment and the V-ISAN as a

whole (see Annex B). Further, it should be separated into groups after every four hexadecimal digits or

check character using either a blank space or a hyphen. No internal meaning shall be ascribed to any

combination of digits within these groups.
EXAMPLE ISAN RRRR-RRRR-RRRR-EEEE-X-VVVV-VVVV-Y
or
ISAN RRRR RRRR RRRR EEEE X VVVV VVVV Y
In the above example:

— “RRRR-RRRR-RRRR-EEEE” represents a registered ISAN for a specific audiovisual work.

1) When presented in hexadecimal form, an ISAN is composed of a 12-character root segment (“RRRR-RRRR-

RRRR”) followed by a four-character segment (“EEEE”) for the identification of episodes or parts of an audiovisual

work (see ISO 15706-1).
© ISO 2021 – All rights reserved
---------------------- Page: 8 ----------------------
ISO/FDIS 15706-2:2021(E)

— “X” represents the check character for that ISAN, calculated in accordance with ISO 15706.

— “VVVV-VVVV” represents the version identifier segment linked to that ISAN. (The combination of the ISAN

and the version identifier segment constitute the V-ISAN.)

— “Y” represents the check digit for that V-ISAN. It is computed over the positions labelled “R”, “E” and “V”. The

position labelled “X” is not included in the computation of “Y”. Figure B.1 shows the range of positions covered

by each check character.
Additional encodings of V-ISAN are specified in Annexes C and D.

4.4 To avoid confusion, a V-ISAN version segment of 0 (i.e. 0000-0000) shall be treated as an ISAN

without a version segment.

4.5 V-ISAN version segment range 1 (0000 0001 in hexadecimal) to 4 026 531 839 (EFFF FFFF in

hexadecimal) are public numbers and shall be issued from and tracked within the V-ISAN register.

4.6 V-ISAN version segment range 4 026 531 840 (F000 0000 in hexadecimal) to 4 294 967 295

(FFFF FFFF in hexadecimal) are reserved for private numbers and shall not be issued from within

the V-ISAN register. This corresponds to version segments where the first four bits are 1111 (i.e.,

hexadecimal value F). Private numbers are reserved solely for internal applications (e.g., to track

internal edits during the preparation of a version for public release) as determined by a V-ISAN

registrant who may self-assign such V-ISANs on a non-registered basis. Any time a V-ISAN with a

private number is encountered external to the organization that created it, it shall be treated as if it has

no version segment at all (i.e., treated as an ISAN without a version segment).

4.7 It is not meaningful to express information on a version or related content entity without reference

to a specific audiovisual work. Therefore, the version segment shall only appear in conjunction with the

ISAN for the work in question and in the form of a V-ISAN. The version segment of a V-ISAN shall have

no meaning on its own.

4.8 A V-ISAN shall signify only that it is a globally unique identifier that has been registered with an

agency of the V-ISAN system.
5 V-ISAN issuance

5.1 A V-ISAN shall be issued only in reference to a valid ISAN registered in the ISAN system in

accordance with ISO 15706.
5.2 V-ISAN shall be issued to applicants by the Registration Authority.

5.3 Applicants for V-ISAN shall provide all of the registration data required by the Registration

Authority prior to being issued a V-ISAN. The Registration Authority shall ensure that required

registration data (see Annex E) is recorded in the V-ISAN register for each V-ISAN issued.

5.4 A V-ISAN may be assigned before, during, or after the production of the associated version of an

audiovisual work, providing that the source work has been assigned an ISAN that is valid.

6 Affixing and displaying the V-ISAN

6.1 The V-ISAN for a version or content entity related to an audiovisual work shall be incorporated

permanently in, or affixed to, all occurrences of that specific version or content entity to the extent that

it is technically feasible to do so.
© ISO 2021 – All rights reserved
---------------------- Page: 9 ----------------------
ISO/FDIS 15706-2:2021(E)

6.2 The V-ISAN should be included in the documentation, advertising and packaging associated with

the specific version or content entity related to an audiovisual work.

6.3 The inclusion of a V-ISAN with a version of an audiovisual work shall conform to the specifications

of ISO 15706 for inclusion of an ISAN with the audiovisual work.

6.4 The characters A to F appearing in a V-ISAN and A to Z appearing in either check character should

be displayed in upper-case letters when the V-ISAN is presented in human-readable form. However, the

lower-case and upper-case forms of these characters shall be treated as equivalent.

6.5 If a version of an audiovisual work is issued in a specific product item that has its own product

numbering system (e.g., a Global Trade Item Number of the EAN.UCC system), the V-ISAN shall

be displayed on the container and/or packaging of that product immediately below and clearly

distinguished from any product numbers associated with the item.

6.6 Further details regarding methods of affixing a V-ISAN to a version of an audiovisual work are

explained in the user’s guide that is available from the Registration Authority.
7 V-ISAN system overview
7.1 General

At the centre of the V-ISAN system is the Registration Authority, the entity responsible for overseeing

the V-ISAN system. The Registration Authority maintains a register of all V-ISAN registration records,

issues new V-ISANs upon proper request, and establishes the necessary operational policies and

procedures to keep the system functioning properly.

The V-ISAN system shall work cooperatively with the ISAN system. Many V-ISAN functions require the

cooperation of the ISAN system. For example:

— V-ISANs cannot be issued unless the associated ISAN has already been issued and is valid;

— V-ISAN registration records contain information about the version, but not about the work upon

which the version is based. That data shall be obtained from the ISAN system.

ISO/FDIS 15706-2:2021(E)

NOTE The dashed lines indicate communication paths connecting to the resolution service provider(s).

These paths are not defined in detail within this document.
Figure 2 — Overview of communication paths between entities in the V-ISAN system

V-ISAN users conduct their business through the Registration Authority who process all V-ISAN

registration (issuance) requests, registration record updates, and V-ISAN registration data queries

(requests for data contained within the registration record).

The V-ISAN is a version identifier; it is not an exhaustive descriptive data repository. When users need

information that is not part of the registration record, and therefore not part of the V-ISAN system

metadata, they need to contact a resolution service provider. The V-ISAN registration record contains

the Internet domain name or intellectual property (IP) address of the designated resolution service

provider for each V-ISAN (if the V-ISAN’s registrant has provided one). This, or any other resolution

service provider, may then be contacted via a defined syntax to obtain further descriptive data related

to a particular V-ISAN.

The various entities interact with one another in different ways depending on the system action. The

exact steps in each system action may differ depending on the specifics of the situation, but in general,

all entities should use XML as their electronic encoding specification when exchanging data.
