10、 standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fie

11、lds 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 technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted

12、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 Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an Internati

13、onal 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 subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/I

14、EC 9973 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 24, Computer graphics, image processing and environmental data representation. This second edition cancels and replaces the first edition (ISO/IEC 9973:1994), which has been technically revised.

15、BS ISO/IEC 9973:2006vIntroduction This International Standard provides a set of procedures for the registration of items. In this context, items refers to all registered items defined within the standards developed by ISO/IEC JTC 1/SC 24. ISO/IEC JTC 1/SC 24 is responsible for preparing standards fo

16、r interchange of information involving computer graphics, image processing and environmental data representation. All proposed and anticipated standards in this area share certain classes of items that are allowed to vary across implementations of the standard. Nevertheless, there is a strong incent

17、ive 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 for registration of certain items. Standards shall expressly identify items to be registered. When a standard is publishe

18、d, those categories of items identified for registration are automatically included in the registry. This International Standard specifies procedures to be followed in preparing and maintaining the ISO/IEC International Register of Items, containing the identifiers and associated information assigne

19、d 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 current classes of registered items for relevant International Standards developed by ISO/IEC JTC 1/SC 24. The classes of

20、registered items are listed with the registry and therefore maintained separately from this International Standard. This International Standard will be updated as necessary for future standards developed by ISO/IEC JTC 1/SC 24. Publication of the register promotes international information exchange

21、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 procedure. However, as a matter apart from registration, the registered items may, but need not, be the subject of an intern

22、ational, 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), it would be appropriate for the registered identifier of the item(s) to be indicated in that standard. Annex A identif

23、ies the information needed for registration proposals. Annex B contains example proposal and register forms. Annex C contains language binding guidelines for registry submission. Annex D contains encoding guidelines for registry submission. BS ISO/IEC 9973:2006blank1Information technology Computer g

24、raphics, image processing and environmental data representation Procedures for registration of items 1 Scope This International Standard specifies procedures to be followed in preparing, maintaining and publishing a register of identifiers and meanings for standards under the direction of ISO/IEC JT

25、C 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 define data structures used by the ISO/IEC JTC 1/SC 24 standards. All registered items are intended for reuse within other a

26、djunct standards. Registration procedures do not assign values of identifiers that are defined as being workstation-dependent by specific graphics standards. The register of font appearance in the ISO/IEC JTC 1/SC 24 register for graphical items is not intended to address the broader issues of gener

27、al-purpose font registration. The procedures apply to registration of individual items within classes as reserved for registration in the International Standards developed by ISO/IEC JTC 1/SC 24. 2 Normative references This standard requires no normative references. 3 Terms and definitions For the p

28、urposes 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 the semantics or technical meaning of the item. Clarification does not result in a change to the registration status of the

29、 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 classes of registered items that are applicable to computer graphics, environmental data representation and/or implementation

30、 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 19135. BS ISO/IEC 9973:20062 3.3 deprecated item registered items which have been found obsolete or to which an objection or

31、 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 of this registered item. 3.4 Generalized Drawing Primitive GDP primitive required for graphical item registration 3.5 noti

35、O/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 9973 is established in agreement with ISO and is approved by the ISO Technical Management Board as part of a ten-year ag

36、reement 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/prods-services/catalogue/maralist.html 4.2 Responsibilities of registration authority The Registration Authority shall m

37、aintain a register of identifiers and meanings assigned to items in the register. Upon request, the registration authority shall distribute an information pack containing a description of the register and how to submit proposals. The responsibilities of the registration authority are more completely

38、 described in Clause 5 and Figures 1 and 2. BS ISO/IEC 9973:200635 Register of items 5.1 Availability of registers The contents of any registers established under the procedures of this International Standard shall be available to the public under the terms and conditions set by the registration aut

39、hority. 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 and additions The establishment of a register under the procedures of this International Standard allows for multiple catego

40、ries of items including: identifiers and meanings assigned to graphical items; profiles of International Standards, and environmental data representation items. With regard to initial assignment of identifiers and meanings to registered items and subsequent additions to the register, the responsibil

41、ities 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 referring proposals to the Secretariat of ISO/IEC JTC 1/SC 24 or by a vote within the subcommittee, whether each proposal should b

42、e accepted, accepted subject to amendment, or rejected according to stated criteria. Criteria for rejecting a proposal include: 1) incomplete or incomprehensible definition of item(s); 2) incorrect or incomplete language binding or data encoding (reference Annex D Language binding guidelines); 3) ex

43、istence 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) inadequate justification for inclusion in the register. Voting discrepancies shall be resolved following attempts to meet objectio

44、ns 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 of a section name followed by a unique registration number within the section, which is: 1) the value of identifier of the

45、 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 notification recipients of the items accepted for registration. This is accomplished by sending the table of contents and a cros

46、s-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 of a proposal has been completed; g) to add new classes of items to the current list of classes; h) to provide copies of

47、the register and associated documents to members of the public on request; i) to distribute the current list of classes of items upon request.
