6 ISO/IEC 10728: 1993 (E) 0 ISO/IEC 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 technical committees established by the respective organization to deal with particular Gelds of technical activity. ISO and IEC technical committees collaborate in Gelds of mutual interest. Other international organizations, govemmental and non-govemmental, 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. Draft International Standards adopted by the joint technical committee arc circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. International Standard ISO/IEC was prepared by Joint Technical Committee ISO/IEC JTC 1, Infomtion teclznology, Sub-Committee SC 21, Infomtion retrieval, transfer- and mmuzgement for open Systems interconnection (OSI). Annex A forms an integral part of this International Standard. Annex B is for information only. vi

9 INTERNATIONAL STANDARD 0 ISO/IEC ISOiIEC 10728:1993 (E) Information technology - Information Resource Dictionary System (IRDS) Services Interface 1 Scope The IRDS series of International Standards specifies a Software tool that tan be used to describe and potentially control an enterprise s information resources. It defines the structure and part of the content of the data to be maintained at the IRD Definition Level, and the structure of the data to be maintained at the IRD Level. It also defines the Services to be provided for maintaining and retrieving data at both levels. Further details of the IRDS series of Standards are to be found in ISO/IEC This International Standard specifies a Services Interface that gives any program full access to all IRDS services, through whatever extemal cal1 interface is provided by the language in which the program is written. The body of this International Standard defines the semantics of this interface, and also specifies the language bindings for ISO Pascal (ISO 7185). Language bindings for other ISO Standard programming languages are provided as separate Standards. This International Standard makes no assumptions about an implementation environment, and assumes no specific nm-time or compile-time interfaces. 2 Normative references The following Standards containprovisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and Parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the Standards listed below. Members of IEC and ISO maintain registers of currently valid International Standards.
