8、rldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented o

9、n that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted

10、 in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standa

11、rd requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15706-2 was prepared b

12、y Technical Committee ISO/TC 46, Information and documentation, Subcommittee SC 9, Identification and description. ISO 15706 consists of the following parts, under the general title Information and documentation International Standard Audiovisual Number (ISAN): Part 2: Version identifier At the next

13、 revision, ISO 15706:2002 will be cancelled and replaced as ISO 15706-1. BS ISO 15706-2:2007vIntroduction This part of ISO 15706 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 a

14、udiovisual work. It supplements the International Standard Audiovisual Number (ISAN) specified in ISO 15706:2002 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 p

15、art of ISO 15706 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

16、 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 functioni

17、ng properly. Registration agencies are appointed by the Registration Authority to make 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. These registration agencies conn

18、ect to the register maintained by the Registration Authority and provide services to applicants for new ISAN version identifiers, registrants of existing ISAN version identifiers, and other users. They do so by providing user access to the information in the version register and by making registrati

19、on requests to the register on behalf of applicants for new version registrations. To reduce the operational burden on the register associated with user registration information lookups, registration agencies can keep local copies of all or part of the version registration database in accordance wit

20、h data caching rules established by the Registration Authority. 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

21、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 reg

22、ister itself is not intended for reverse lookups (where one requests the ISAN version identifiers associated with specific metadata), but that does not preclude third parties from providing such a service. BS ISO 15706-2:2007blank1Information and documentation International Standard Audiovisual Numb

23、er (ISAN) Part 2: Version identifier 1 Scope This part of ISO 15706 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 Num

24、ber (ISAN) system defined in ISO 15706. An ISAN combined with the version segment specified in Clause 4 of this part of ISO 15706 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

25、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 audiovis

26、ual 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 forma

27、t) 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 conte

28、nt or to the audiovisual work itself. This part of ISO 15706 specifies the basic systems and procedures to support the issuance and administration of V-ISANs. 2 Normative references The following referenced documents are indispensable for the application of this document.

32、ms and definitions given in ISO 15706 and the following apply. 3.1 ISAN International Standard Audiovisual Number number allocated for the unique identification of an audiovisual work in accordance with ISO 15706. 3.2 private number reserved V-ISAN (3.6) that has meaning only in the context of the o

33、rganization that created it, is not registered with the V-ISAN register and is not normally exchanged between entities NOTE Since different entities may assign the same private number to different versions of a work, these numbers are not intended to be exchanged between entities. 3.3 resolution ser

34、vice provider entity that maintains and makes available a set of metadata associated with specific V-ISANs NOTE 1 While the term resolution service provider is used in its singular form, there may be any number of providers. NOTE 2 The provider optionally listed in the V-ISAN registration informatio

35、n is called the “designated” resolution service provider. 3.4 version particular aggregation of elements that affects the content of an audiovisual work NOTE Any change that affects the content of an audiovisual work (e.g. artistic content, language, editing or technical format) and which requires s

36、eparate identification for the use or exploitation of that specific content can be treated as a new version for the purposes of assigning a V-ISAN. See Annex A. 3.5 version segment 32-bit version segment specified in this part of ISO 15706 3.6 V-ISAN unique identifier composed of a registered ISAN i

37、n combination with an appended version segment for a specific version or other content derived from or directly related to an audiovisual work, and allocated in accordance with this part of ISO 15706 3.7 V-ISAN Authority Registration Authority appointed by ISO for the purpose of administering the V-

38、ISAN registration system in accordance with the specifications of this part of ISO 15706 NOTE The V-ISAN Authority appoints V-ISAN registration agencies, maintains the V-ISAN register, issues new V-ISANs, and ensures that the same V-ISAN is never issued twice. 3.8 V-ISAN distributed query system sys

40、 such as the associated ISAN, the V-ISAN registration information, and descriptive information related to the audiovisual work or unique to that version of the audiovisual work. 3.10 V-ISAN register database of registered V-ISANs and the associated V-ISAN metadata necessary for the operation of the

41、V-ISAN system 3.11 V-ISAN registrant entity associated with the registration of a particular V-ISAN NOTE The V-ISAN registrant can be the original applicant or the entity currently responsible for keeping the required V-ISAN registration information and metadata up to date. 3.12 V-ISAN registration

42、agency entity appointed by the V-ISAN Authority for the purpose of conveying V-ISANs to registrants and providing facilities for the registrants interactions with the V-ISAN system NOTE 1 While the term V-ISAN registration agency is used in its singular form, there may be any number of authorized V-

43、ISAN registration agencies. NOTE 2 Metadata facilities maintained by resolution service providers are excluded from this definition. 3.13 V-ISAN registration information administrative class of V-ISAN metadata that uniquely identifies the V-ISAN registrant and provides other pertinent information re

45、f a 64-bit ISAN1)that has been registered in accordance with ISO 15706:2002, 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 t

46、o F of the Latin alphabet. See Figure 1. 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). BS ISO 15706-2:20074

47、 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 pro

48、cessing 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 hy

49、phen. 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. “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 s
