12、or 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 o

13、rganization 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 tech

14、nology, 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 Standar

15、ds 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 sub

ISO/IEC 11179-5 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 32, Data management and interchange. This second edition cancels and replac

17、es the first edition (ISO/IEC 11179-5:1995), which has been technically revised.

19、S/ISO/IEC 11179-5-2005 ITIC 2006 - All rights reserved 1Information technology Metadata registries (MDR) Part 5: Naming and identification principles 1 Scope This part of ISO/IEC 11179 provides instruction for naming and identification of the following administered items: data element concept, conce

20、ptual domain, data element, and value domain. It describes the parts and structure of identification. Identification is narrowly defined to encompass only the means to establish unique identification of these administered items within a register. It describes naming in an MDR; includes principles an

21、d rules by which naming conventions can be developed; and describes example naming conventions. The naming principles and rules described herein apply primarily to names of data element concepts, conceptual domains, data elements, and value domains. When “administered item“ is used in this part of I

22、SO/IEC 11179, it is understood to refer specifically to these four items. This part of ISO/IEC 11179 should be used in conjunction with those that establish rules and procedures for attributing, classifying, defining, and registering administered items. In Annex A, all of the examples are given with

23、 English terminologies. However, there is an intention that those rules be effective in other national languages, even in those languages that use ideographs such as Japanese, Chinese, or Korean, when the terminologies used in the name are controlled properly. Annex B contains a version of the rules

24、 for Asian languages. It is out of scope of the naming rules to establish semantic equivalence of the naming among different languages. Naming must be supplemented by other methods such as ontologies or controlled vocabularies in establishing semantic equivalence. 2 Normative references The followin

36、unique data identifier within the register of a Registration Authority. The combination of registration authority identifier, data identifier, and version identifier shall constitute a unique identification of an administered item. See ISO/IEC 11179-6 for detailed information. A data identifier is a

37、ssigned for any administered item that is registered. Concurrently, or thereafter, the administered item may be classified according to ISO/IEC 11179-2, specified according to ISO/IEC 11179-3:2003, defined according to ISO/IEC 11179-4, named according to ISO/IEC 11179-5, and registered according to

38、ISO/IEC 11179-6. 5 Identification The registration authority identifier (RAI), data identifier (DI), and version identifier (VI) constitute the international registration data identifier (IRDI). An IRDI is required for an administered item. Data identifiers are assigned by a Registration Authority;

39、data identifiers shall be unique within the domain of a Registration Authority. Requirements for a Registration Authority, and a discussion of the IRDI, appear in ISO/IEC 11179-6. As each Registration Authority may determine its own DI assignment scheme, there is no guarantee that the DI by itself w

40、ill uniquely identify an administered item. For example, if two RAs both use sequential 6-digit numbers, there may be two administered items with the same DIs; however, the administered items will almost certainly not be the same. Both the DI and the RAI are necessary for identification of an admini

41、stered item.

42、, then a new version of the administered item shall be created and registered. The registrar shall determine these attributes. In such a case, a VI is required to complete the unique identification of an administered item. For further guidance, see ISO/IEC 11179-6. An IRDI can serve as a key when ex

43、changing data among information systems, organizations, or other parties who wish to share a specific administered item, but might not utilize the same names or contexts. ISO/IEC 11179 does not specify the format or content of a unique DI. 6 Names 6.1 Names in a registry An administered item shall h

44、ave at least one name within a registry of a Registration Authority. If there are other names by which the administered item is known, preferred names may be identified. Any administered item in the Registry can be subject to naming conventions. The annexes show examples of naming conventions applie

45、d to several administered items. Others can be developed by extension of the Principles. An administered item shall have at least one name within a context. See ISO/IEC 11179-3 for detailed information. 6.2 Naming conventions Each name for an administered item is specified within a context. A naming

46、 convention describes what is known about how names are formulated. A naming convention may be simply descriptive; e.g., where the Registration Authority has no control over the formulation of names for a specific context and merely registers names that already exist. Alternatively, a naming convent

47、ion may be prescriptive, specifying how names shall be formulated, with the Registration Authority (or an equivalent authority) expected to enforce compliance with the naming convention. The objectives of a prescriptive naming convention may include name consistency, name appearance, and name semant

48、ics. An effective naming convention can also enforce the exclusion of irrelevant facts about the administered item from the name, such as the input source of a data element or its field position in a file. A naming convention may be specified in a reference document. A naming convention shall cover

49、all relevant documentation aspects. This includes, as applicable, the scope of the naming convention, e.g. established industry name; the authority that establishes names; semantic rules governing the source and content of the terms used in a name, e.g. terms derived from data models, terms commonly used in the discip
