38、03 All rights reserved viiForeword 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 Internationa

39、l Standards through technical 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 I

40、SO 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 in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical comm

41、ittee is to prepare International Standards. Draft International Standards 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. In exceptional circumst

42、ances, the joint technical committee may propose the publication of a Technical Report of one of the following types: type 1, when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts; type 2, when the subject is still under technical dev

43、elopment or where for any other reason there is the future but not immediate possibility of an agreement on an International Standard; type 3, when the joint technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the a

44、rt”, for example). Technical Reports of types 1 and 2 are subject to review within three years of publication, to decide whether they can be transformed into International Standards. Technical Reports of type 3 do not necessarily have to be reviewed until the data they provide are considered to be n

45、o longer valid or useful. 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/IEC TR 20943-1:2003, which is a Technical Report of type 3, was

46、 prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 32, Data management and interchange. ISO/IEC 20943 consists of the following parts, under the general title Information technology Procedures for achieving metadata registry (MDR) content consistency : Note

47、: Parts 2 and 3 are currently under development. Part 1: Data elements Part 2: XML structured data Part 3: Value domains ISO/IEC TR 20943-1:2003(E) viii ISO/IEC 2003 All rights reservedIntroduction The exchange of metadata between metadata registries based on International Organization for Standardi

48、zation/International Electrotechnical Commission (ISO/IEC) 11179 Information technology metadata registries (MDR), depends not only on registry software that conforms to the standard, but also on metadata contents that are comparable between registries. While the standard has provisions for data spe

49、cification and registration, there are pragmatic issues pertaining to populating the registries with content. Based on the experiences of organizations that are implementing the standard, a Technical Report to explore content issues will help current and future users. Metadata registries can be used to register data elements, value domains, and associated attributes for many kinds of organizational data resource collections. Metada
