12、Foreword ISO (the International 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 techni

13、cal committees established by 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

14、 in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different appr

15、oval criteria needed for the different types of document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibility that some of the elements of this document may be the subje

16、ct of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). A

The committee responsible for this document is ISO/IEC JTC 1, Information technology, SC 32, Data Management and Interchange. This third edition cancels and replaces the second edition (ISO/IEC 11179-5

19、:2005), which has been technically revised. ISO/IEC 11179 consists of the following parts, under the general title Information Technology Metadata registries (MDR): Part 1: Framework Part 2: Classification Part 3: Registry metamodel and basic attributes Part 4: Formulation of data definitions Part 5

20、: Naming principles Part 6: Registrationiv ISO/IEC 2015 All rights reservedBS ISO/IEC 11179-5:2015ISO/IEC 11179-5:2015(E) Introduction This part of ISO/IEC 11179 contains both principles and rules. Principles establish the premises on which the rules are based. Registry users may enforce rules as an

21、 application of this part of ISO/IEC 11179. A naming convention is a convention (a set of rules) about names. Many naming conventions have much in common, whether it is defining a method of specifying names for common usage across application systems, or developing an organizations internal policy o

22、n the choice of XML tags for data interchange. A naming convention may be based on principles. In addition, it may contain formal and informal inputs, such as guidelines, recommendations, company policies, programming conventions, specifications, procedures, and so on. The purpose of this part of IS

23、O/IEC 11179 is to describe and specify these common features of naming conventions. This part of ISO/IEC 11179 is intended to have broad applicability, including areas outside of Metadata Registries. The goal of any naming convention is to allow development of names for items that have maximum clari

24、ty and transparency of meaning, combined with concision, demanding minimal effort of interpretation by the end user, subject to the constraints of the system under which the items are processed. A naming convention can be used to form names by which information about the data is expressed, in a simp

25、lified but still understandable grammar compared to natural language rules. Ideally, the names resemble summaries of the formal definition of the information being named. In a metadata registry, one name may be designated as the “registry name,” derived by describing the content of a metadata item i

26、n a structured way, using a set of rules, i.e. by application of a formalized naming convention. Other names for the same metadata entity may occur in any context. For example, these may be software system names, programming language names, report header names, data interchange (e.g. XML) names, and

27、 names in other natural languages. Names may have varying levels of rigor applied to their formation and usage. The collection and display of all names used by any single metadata item can be a major benefit of a metadata registry. The process of deriving names from concept systems and arranging sem

28、antic components with a naming convention forms a set of consistent, meaningful registry names. Names from other contexts, which may or may not have been formed with naming conventions, and therefore may have little or no semantic content, are collected and related to the registry name, thus, contri

29、buting in a valuable way to enterprise data management. Edition 3 of ISO/IEC 11179-3 uses the term designation in reference to most metamodel items except for the classes Namespace and Naming Convention. The designations for these classes were adopted in deference to commonly accepted usage. This pa

30、rt of ISO/IEC 11179 will continue to use the term name for constructs that, for purposes of this part of ISO/IEC 11179, are interchangeable with designation. NOTE Items from the metamodel described in Edition 3 of ISO/IEC 11179-3 are italicized in this part of ISO/IEC 11179. Most multi-word designat

31、ions also contain underscores between words in ISO/IEC 11179-3; the underscores have been omitted in this part of ISO/IEC 11179 for readability. The naming principles and rules described in this part of ISO/IEC 11179 apply primarily to names of concepts, data element concepts, conceptual domains, da

32、ta elements, and value domains, but can be extended to any registry content. Differing naming conventions may be applied to different sets of designatable items. This part of ISO/IEC 11179 should be used in conjunction with those which establish rules and procedures for attributing, classifying, def

33、ining, and registering items 1) . 1) Refer to 11179-6 Ed. 3 for a discussion of identification. ISO/IEC 2015 All rights reserved vBS ISO/IEC 11179-5:2015ISO/IEC 11179-5:2015(E) This part of ISO/IEC 11179 may be used for applications that are unrelated to ISO/IEC 11179-3, i.e. this part of ISO/IEC 11

34、179 has broad applicability for use in describing naming conventions for almost any need or purpose. The same principles apply. In Annex A, all of the examples are given with English terminologies. However, there is an intention that those rules be effective in other natural languages, even in those

35、 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 for Asian languages. It is out of scope of the naming rules to establish semantic equivalence of names among different languag

36、es. Naming must be supplemented by other methods such as ontologies or controlled vocabularies in establishing semantic equivalence. This part of ISO/IEC 11179 may be applied to ISO/IEC 11179-3, i.e. describing naming conventions associated with designations of designatable items and other features

37、of the metamodel. The following are examples of designations in the metamodel: the designation of a data element (class name: Designation; attribute: sign); the designation of classification scheme name; etc. Annex C contains a Concordance Table relating items in this part of ISO/IEC 11179 to items

38、in ISO/IEC 11179-3. This part of ISO/IEC 11179 does not make requirements on any specific set of conventions, e.g. specific semantic, syntactic, or lexical requirements for names.vi ISO/IEC 2015 All rights reservedBS ISO/IEC 11179-5:2015Information technology Metadata registries (MDR) Part 5: Naming

39、 principles 1 Scope This part of ISO/IEC 11179 provides instruction for naming of the following items, as defined in ISO/IEC 11179-3: concept, data element concept, conceptual domain, data element, and value domain.
