13、International Organization for Standardization) is a worldwide 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
14、 has been established has the right to be represented on 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 electrotechnic
15、al standardization. International Standards are drafted 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 bo
16、dies for voting. Publication as an International Standard 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 an
17、y or all such patent rights. ISO 21047 was prepared by Technical Committee ISO/TC 46, Information and documentation, Subcommittee SC 9, Identification and description. BS ISO 21047:2009ISO 21047:2009(E) ISO 2009 All rights reserved vIntroduction The purpose of the International Standard Text Code (I
18、STC) is to enable the efficient identification of textual works. The ISTC provides a means of uniquely and persistently identifying textual works in information systems and of facilitating the exchange of information about those textual works between authors, agents, publishers, retailers, libraries
19、, rights administrators and other interested parties, on an international level. BS ISO 21047:2009BS ISO 21047:2009INTERNATIONAL STANDARD ISO 21047:2009(E) ISO 2009 All rights reserved 1Information and documentation International Standard Text Code (ISTC) 1 Scope This International Standard specifie
20、s the International Standard Text Code (ISTC) which is applicable to any textual work, whenever there is an intention to produce such a textual work in the form of one or more manifestations. It provides an identification data element for applications that record and exchange information about textu
21、al works and related manifestations. For example, the ISTC can be used for the purposes of collocating subsequent manifestations of the same textual work or derivations of the same textual work in applications involving electronic rights administration or information retrieval. The ISTC is not appli
22、cable to manifestations of a textual work, including any physical products (e.g. a printed article) or electronic formats (e.g. an electronic book). Manifestations of textual works are the subject of separate identification systems. The allocation of an ISTC to a textual work gives no meaning or val
23、ue as legal evidence regarding the copyright status of, or any intellectual property rights in, the textual work. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated refere

32、extual form (e.g. a novel, a play, a translation) but excludes any aspects of physical form (e.g. print, electronic) in which such expressions are made manifest. See textual manifestation (3.8). 3.13 title word, phrase, character or group of characters, usually appearing on textual manifestations (3

34、ic structure and syntax An ISTC shall consist of 16 hexadecimal digits using numerals 0 to 9 and letters A to F. It shall be made up of the following parts: registration element; year element; textual work element; check digit. When an ISTC is displayed in written or printed form, the letters ISTC s
35、hall precede it. To assist in accurate transcription of the ISTC, all parts should be separated from each other by hyphens or spaces, as shown in the following examples. EXAMPLES ISTC 0A9 2002 12B4A105 7 ISTC 0A9-2002-12B4A105-7 4.2 Registration element The first part of an ISTC shall be the registr
36、ation element. The registration element shall consist of three hexadecimal digits. The registration element shall be allocated by the ISTC Registration Authority for its internal identification purposes. 4.3 Year element The second part of an ISTC shall be the year element. The year element shall co
37、nsist of the four digits representing the year in which the ISTC is allocated. 4.4 Textual work element The third part of an ISTC shall be the textual work element. The textual work element shall consist of eight hexadecimal digits. The textual work element shall be allocated by the ISTC Registratio
38、n Authority to the textual work. 4.5 Check digit The fourth and final part of an ISTC shall be the check digit. The check digit shall be calculated on a MOD 16-3 system defined in accordance with ISO/IEC 7064. See Annex A for further details. 5 Allocation of an ISTC See Annex B for the principles fo

40、The principal tasks of the ISTC Registration Authority are outlined in Annex C. 7 Association of an ISTC with ISTC metadata An ISTC shall be associated with ISTC metadata (see Annex D) about the textual work it identifies by means of a register.

46、that textual work (a “creator”), or from any person or organization authorized to represent the creator. Where reasonable investigation has not located and could not locate a creator or an authorized representative of a creator, any person or organization may request an ISTC. B.1.2 The same ISTC sha
47、ll not be allocated to more than one textual work. B.1.3 The same textual work shall not be allocated more than one ISTC. B.1.4 Registrants shall supply metadata about the textual work being registered in accordance with the specifications established by the ISTC Registration Authority. See B.2 and
48、Annex D. B.1.5 Textual works that are eligible for an ISTC include any distinct abstract entity, predominantly composed of a combination of words, that can be described to satisfy the ISTC metadata requirements. B.1.6 In order to be assigned an ISTC, the declared metadata for any textual work at the
49、 time of registration shall contain at least one element pertaining to the work itself that distinguishes it from every other textual work to which an ISTC has already been assigned. If two entities share identical ISTC metadata, they shall be treated as the same textual work and shall have the same ISTC. B.1.7 An ISTC may be allocated to a textual work at any time; this includes retrospective allocation of an ISTC to textual works already in existence before the implementation of this International Standard.
