22、3(E) iv ISO 2003 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body

23、interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotech

24、nical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by t

25、he technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent right

28、plications for individual users to mainframe term-bank systems operated by major companies and governmental agencies. Termbases are comprised of various sets of data category and are based on various kinds of data model. Terminological data often need to be shared and reused in a number of applicati

29、ons, and this sharing is usually accomplished using intermediate formats. To facilitate co-operation and to prevent duplicate work, it is important to develop standards and guidelines for creating and using terminological data collections as well as for sharing and exchanging data. The meta-model de

30、fined in this International Standard fits into an integrated approach to be used in analysing existing terminological data collections and in designing new ones, which are typically processed using relational or text-based data management systems. Terminological data collections can also be stored a

31、s structured documents with markup based on formats that are typically defined using Standard Generalized Markup Language (SGML), defined in ISO 8879 12, or eXtensible Markup Language (XML), which is based on SGML but amended for use on the World Wide Web by the World Wide Web Consortium (W3C). An i

32、ntegrated approach eases the tasks of importing data from a flat file with markup into a database and of exporting data from a database to a structured document. Another motivation for an integrated approach, as opposed to entirely separate approaches for databases and structured documents, is that

33、XML-based formats are now being processed in new ways, similar to traditional database management systems. For example, XML files are being queried and updated directly without importing data into traditional database environments. This integrated approach to analysis and design consists of two leve

34、ls of abstraction. The first (and most abstract) level of the integrated approach is the meta-model level. The meta-model level, which could also be called the abstract conceptual data model level, supports analysis and design at a very general level. The second level is the data model level. At the

35、 data model level, the designer of the terminological data collection has the possibility to make various choices, based on real-life needs. First, designers must determine the form of representation most appropriate for their terminological data, addressing the following choices: whether to use a r

36、elational database or a flat file with markup; whether the data will be used primarily for queries and updates, and be represented in some database management system and, if this is the case, what system to use; whether the data will be used primarily for sharing and interchange, and be represented

37、in a flat file with markup. For the purposes of this International Standard it is assumed that all flat files will use XML markup. Once the choice between a database management system and a flat file with XML markup has been made, a data model must be chosen. For a relational database, a typical met

38、hod of describing a data model is an entity- relationship diagram. For an XML document, a typical method of describing a data model is a Document Type Definition (DTD). An alternative method, using what is called an “XML schema”, is provided by the W3C. In the future, it will be possible to use more

39、 abstract methods of describing an XML format. A specific implementation of the meta-model for terminology markup expressed in XML is called a terminological markup language (or TML), which can be described on the basis of a limited number of characteristics, namely how the TML expresses the structu

40、ral organization of the meta-model (i.e. the expansion trees of the TML), the specific data categories used by the TML and how they relate to the meta-model,This standard may only be used and printed by approved subscription and freemailing clients of the SABS.ISO 16642:2003(E) vi ISO 2003 All right

41、s reserved the way in which these data categories can be expressed in XML and thus anchored on the expansion trees of the TML, i.e. the XML style of any given data category, and the vocabularies used by the TML to express those various informational objects as XML elements and attributes according t

42、o the corresponding XML styles. Some of the examples in this International Standard are instances of the MSC (MARTIF with Specified Constraints) and Geneter formats as described in Annex B and Annex C respectively.This standard may only be used and printed by approved subscription and freemailing cl

The mechanisms for implementing constraints in a TML are defined in this International Standard, but not the specific constraints

45、for individual TMLs, except for the three TMLs defined in Annexes B to D. This International Standard is designed to support the development and use of computer applications for terminological data and the exchange of such data between different applications. It does not standardize data categories

46、and methods for the specification of data structures which are specified in ISO 12620 and other related International Standards. This International Standard also defines the conditions that allow the data expressed in one TML to be mapped onto another TML and specifies a generic mapping tool (GMT) f
