8、nal Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established b

9、y the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field o

10、f information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft Int

11、ernational Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this docum

12、ent may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 9973 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 24, Computer graphics, image processing and environmental da

13、ta representation. This third edition cancels and replaces the second edition (ISO/IEC 9973:2006), which has been technically revised.iv ISO/IEC 2013 All rights reserved ISO/IEC 9973:2013(E) Introduction This International Standard provides a set of procedures for managing the International Register

14、 of Items. In this context, items are members of classes defined within the standards developed by ISO/IEC JTC 1/SC 24 that may be registered. The set of procedures specified in this International Standard is equally applicable to any standard that includes a provision for registering items in the I

15、nternational Register of Items. Standards that wish to use the International Register of Items may have certain classes of items in common that are allowed to vary across implementations of those standards. There is a strong incentive for implementations using the same registered items to reference

16、them in the same way. Each such standard has the potential to provide for registration of items of certain classes and expressly identifies those classes of items that may be registered. When such a standard is published, those classes of items identified for registration are automatically added to

17、the International Register of Items. The procedures in this International Standard are used in preparing, maintaining, and publishing the International Register of Items. The register includes current classes of items from relevant International Standards whose content can be extended through regist

18、ration. The classes of items are listed within the register and therefore maintained separately from this International Standard. The register also serves as a means to inform all concerned of items already registered and of the specific identifiers assigned to them. Registration provides identifica

19、tion for an item but should not be regarded as a standardization procedure. Annex A identifies the information needed in submitting item proposals. Annex B contains example proposal forms. Annex C contains language binding guidelines for submission of registration proposals. Annex D contains encodin

20、g guidelines for submission of registration proposals.

30、1 Overview Standards that include registration provisions, as specified by this International Standard, are supported by the International Register of Items. The International Register of Items provides the following features: a register of identifiers and meanings that may be shared between related

31、 standards, new instances of concepts in the related standards to be specified by registration, and a repository where both standardized and registered items may be browsed or searched. This International Standard specifies procedures that manage the International Register of Items, which is organiz

32、ed into sections. The International Register of Items is maintained by the registration 2 ISO/IEC 2013 All rights reserved ISO/IEC 9973:2013(E) authority. Proposals related to the International Register of Items are submitted by sponsoring authorities, processed by the registration authority and app

33、roved by the relevant approval body. 4.2 Registration authority 4.2.1 Appointment of a registration authority The registration authority for this International Standard is established in accordance with ISO/IEC Directives, Part 1, Annex H and is approved by the ISO Technical Management Board as part

34、 of a ten- year agreement to maintain the International Register of Items. Contact information for registration authorities of International Standards including this one are maintained and available at http:/ /www.iso.org/iso/standards_development/maintenance_agencies.htm. 4.2.2 Overview of registra

35、tion authority responsibilities The registration authority shall maintain the International Register of Items. Upon request, the registration authority shall distribute information including a description of the International Register of Items and how to submit proposals. Additional information on t

36、he responsibilities of the registration authority is provided in Clause 5 and Figure 1. 4.3 Sponsoring authorities 4.3.1 Authorized sponsoring authorities Proposals for changing the content of the register may be made by the following organizations that are authorized to be sponsoring authorities fo

37、r the purposes of this International Standard: a) any ISO or IEC Technical Committee or Subcommittee; b) any P-member or O-member of ISO/IEC JTC 1 or its subcommittees; c) any international organization having Category A, B, or C liaison status with ISO/IEC JTC 1 or its subcommittees. 4.3.2 Responsi

38、bilities of sponsoring authorities The responsibilities of sponsoring authorities shall be as follows: a) to receive proposals from within their respective countries or organizations; b) to coordinate proposals within their respective countries or organizations, as necessary; c) to ensure that all p

39、roposals are complete and conform to the requirements for the class of an item; d) to ensure, if a language binding and/or encoding is required, at least one language binding and/or data encoding shall be included; e) to forward to the registration authority proposals that are ready to be submitted;

40、 f) to respond to questions and coordinate changes derived from comments received from the registration authority; and g) to disseminate the decisions taken on proposals to their respective countries or organizations. ISO/IEC 2013 All rights reserved 3 ISO/IEC 9973:2013(E) 4.4 Items The Internationa

41、l Register of Items operates under the procedures of this International Standard and allows for varied classes of items within the scope of this International Standard including: graphical items, data structures used by relevant standards, environmental data representation items, and profiles of sta

42、ndards. The addition of a new item to the register increases the range of applicability of that standard, but does not change the basic concepts of the standard. 4.5 Sections A separate section is provided either for a set of classes that are related to a single International Standard or for individ

43、ual classes related to one or more International Standards. A section is populated by one or more classes. The classes may be populated with standardized and/or registered items as specified by the relevant International Standard(s). 4.6 Registration process Proposals for the additions of new items

44、to the register are submitted by a sponsoring authority (see 4.3). The proposal is then evaluated by the Subcommittee Secretariat, the relevant Working Group or by a rapporteur to ensure that its content conforms to the guidelines provided by the relevant International Standard. The steps in the reg

45、istration process are described in terms of the responsibilities of the registration authority (see 5.2). 4.7 Proposal guidelines and forms Annex A specifies general information necessary to submit a proposal to the registration authority. Detailed information for a particular class may be obtained

46、from the registration authority or from the relevant International Standard that specifies that class. Annex B contains example class and registration proposals formatted in forms with supporting text. Annex C provides guidelines for submitting proposals for language bindings for registered items. A

47、nnex D provides guidelines for submitting proposals for encodings of registered items. 4.8 New or revised International Standards International Standards that allow registration as specified by this International Standard shall expressly identify classes of items to be included in the register. Upon

48、 approval of the new or revised International Standard, the Secretary shall receive from the editor of the relevant International Standard a list of the new classes that are identified for inclusion in the register accompanied by the associated standardized items approved for inclusion in the regist

49、er. In addition, the editor shall provide a list of deprecated items, if any. The Secretary shall then provide the lists to the registration authority. When a standard is published, the contents of the lists provided to the registration authority shall be automatically added to the register. The registration authority shall also update the register to include relationships of existing classes to additional standards or parts of standards that use the classes within the scope of this International Standard, as necessary.4
