9、 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 by the respective

10、 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 of information te

11、chnology, 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 International Stand

12、ards 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 document may be the s

13、ubject 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 data representatio

14、n. This second edition cancels and replaces the first edition (ISO/IEC 9973:1994), which has been technically revised. BS ISO/IEC 9973:2006v Introduction This International Standard provides a set of procedures for the registration of items. In this context, items refers to all registered items defi

15、ned within the standards developed by ISO/IEC JTC 1/SC 24. ISO/IEC JTC 1/SC 24 is responsible for preparing standards for interchange of information involving computer graphics, image processing and environmental data representation. All proposed and anticipated standards in this area share certain

16、classes of items that are allowed to vary across implementations of the standard. Nevertheless, there is a strong incentive for implementations using the same registered items to reference them in the same way. Each standard developed by ISO/IEC JTC 1/SC 24, therefore, has the potential to provide f

17、or registration of certain items. Standards shall expressly identify items to be registered. When a standard is published, those categories of items identified for registration are automatically included in the registry. This International Standard specifies procedures to be followed in preparing an

18、d maintaining the ISO/IEC International Register of Items, containing the identifiers and associated information assigned to particular items. The purpose of the register is to inform all concerned of items already registered and of the specific identifiers assigned to them. The register includes cu

19、rrent classes of registered items for relevant International Standards developed by ISO/IEC JTC 1/SC 24. The classes of registered items are listed with the registry and therefore maintained separately from this International Standard. This International Standard will be updated as necessary for fut

20、ure standards developed by ISO/IEC JTC 1/SC 24. Publication of the register promotes international information exchange and avoids duplication of effort in development of application-oriented items. Registration provides identification for an item but should not be regarded as a standardization proc

21、edure. However, as a matter apart from registration, the registered items may, but need not, be the subject of an international, national, or other standard. In these cases, the register shall reference the applicable standard. When such a standard is amended subsequent to registration of an item(s)

22、, it would be appropriate for the registered identifier of the item(s) to be indicated in that standard. Annex A identifies the information needed for registration proposals. Annex B contains example proposal and register forms. Annex C contains language binding guidelines for registry submission. A

23、nnex D contains encoding guidelines for registry submission. BS ISO/IEC 9973:2006blank1 Information technology Computer graphics, image processing and environmental data representation Procedures for registration of items 1 Scope This International Standard specifies procedures to be followed in pre

24、paring, maintaining and publishing a register of identifiers and meanings for standards under the direction of ISO/IEC JTC 1/SC 24. NOTE These procedures may be used to extend any standard developed by ISO/IEC JTC 1/SC 24. Some registration items are graphical in nature; other registration items def

25、ine data structures used by the ISO/IEC JTC 1/SC 24 standards. All registered items are intended for reuse within other adjunct standards. Registration procedures do not assign values of identifiers that are defined as being workstation-dependent by specific graphics standards. The register of font

26、appearance in the ISO/IEC JTC 1/SC 24 register for graphical items is not intended to address the broader issues of general-purpose font registration. The procedures apply to registration of individual items within classes as reserved for registration in the International Standards developed by ISO/

27、IEC JTC 1/SC 24. 2 Normative references This standard requires no normative references. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 clarification non-substantive change to a registered item NOTE A non-substantive change does not change th

28、e semantics or technical meaning of the item. Clarification does not result in a change to the registration status of the registered item. 3.2 class set of items with common properties or that are common in application to a relevant International Standard EXAMPLE This International Standard has clas

29、ses of registered items that are applicable to computer graphics, environmental data representation and/or implementation profiles of International Standards. NOTE Class is used in this context to refer to a set of instances, not the concept abstracted from that set of instances adapted from ISO 191

30、35. BS ISO/IEC 9973:20062 3.3 deprecated item registered items which have been found obsolete or to which an objection or desire to cause the removal of has been raised NOTE Deprecated items will be retained in the register, but marked as “deprecated” to note the recommendation of avoiding the use o

31、f this registered item. 3.4 Generalized Drawing Primitive GDP primitive required for graphical item registration 3.5 notification recipients all member bodies, Category A, B and C liaisons, including sponsoring authorities 3.6 register set of files containing identifiers assigned to items with descr

32、iptions of the associated items as defined by the relevant International Standard ISO 19135 3.7 registration assignment of a permanent, unique and unambiguous identifier to an item with its related descriptive information 3.8 registration authority organization to which management of a register has

33、been designated by ISO Technical Management Board at the proposal of the technical committee concerned 3.9 registry information system on which a register is maintained adapted from ISO/IEC 11179-3 4 The registration authority 4.1 Appointment of a registration authority A qualified and international

34、ly acceptable body concerned with computer elements developed under the scope of ISO/IEC JTC 1/SC 24 is recommended by ISO/IEC JTC 1/SC 24 to ISO/IEC for acceptance by Council to act as the registration authority for the purposes of this International Standard. The registration authority for ISO/IEC

35、 9973 is established in agreement with ISO and is approved by the ISO Technical Management Board as part of a ten-year agreement to maintain the registry. Contact information for Registration Authorities of International Standards including this one are maintained and available at www.iso.org/iso/en

36、/prods-services/catalogue/maralist.html 4.2 Responsibilities of registration authority The Registration Authority shall maintain a register of identifiers and meanings assigned to items in the register. Upon request, the registration authority shall distribute an information pack containing a descri

37、ption of the register and how to submit proposals. The responsibilities of the registration authority are more completely described in Clause 5 and Figures 1 and 2. BS ISO/IEC 9973:20063 5 Register of items 5.1 Availability of registers The contents of any registers established under the procedures

38、of this International Standard shall be available to the public under the terms and conditions set by the registration authority. Portions of the register may be obtained by standards developers at no charge under the terms and conditions set by the registration authority. 5.2 Initial assignments an

39、d additions The establishment of a register under the procedures of this International Standard allows for multiple categories of items including: identifiers and meanings assigned to graphical items; profiles of International Standards, and environmental data representation items. With regard to in

40、itial assignment of identifiers and meanings to registered items and subsequent additions to the register, the responsibilities of the registration authority are specified below and depicted in Figure 1: a) to receive proposals from sponsoring authorities (see Clause 6); b) to ascertain, by referrin

41、g proposals to the Secretariat of ISO/IEC JTC 1/SC 24 or by a vote within the subcommittee, whether each proposal should be accepted, accepted subject to amendment, or rejected according to stated criteria. Criteria for rejecting a proposal include: 1) incomplete or incomprehensible definition of it

42、em(s); 2) incorrect or incomplete language binding or data encoding (reference Annex D Language binding guidelines); 3) existence of an identical item in the register; 4) item class not in register; 5) not-applicable to any of the International Standards developed by ISO/IEC JTC 1/SC 24; 6) inadequa

43、te justification for inclusion in the register. Voting discrepancies shall be resolved following attempts to meet objections raised by negative votes. c) to assign a proposal identifier to each proposal, d) to assign a register identifier to each accepted item. The register identifier shall consist

44、of a section name followed by a unique registration number within the section, which is: 1) the value of identifier of the item, if this is a number or, 2) some appropriate number assigned by the registration authority, if the value of identifier of item is not a number; e) to announce to all notifi

45、cation recipients of the items accepted for registration. This is accomplished by sending the table of contents and a cross-reference list matching the proposal identifier with the registered item; BS ISO/IEC 9973:20064 f) to inform the appropriate sponsoring authority of the results when processing

46、 of a proposal has been completed; g) to add new classes of items to the current list of classes; h) to provide copies of the register and associated documents to members of the public on request; i) to distribute the current list of classes of items upon request.
