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 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.

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 approval 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 or www.iec.ch/members_experts/refdocs ).

ISO and IEC draw attention to the possibility that the implementation of this document may involve the use of (a) patent(s). ISO and IEC take no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the date of publication of this document, ISO and IEC had not received notice of (a) patent(s) which may be required to implement this document. However, implementers are cautioned that this may not represent the latest information, which may be obtained from the patent database available at www.iso.org/patents and https://patents.iec.ch . ISO and IEC shall not be held responsible for identifying any or all such patent rights.

This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 32, Data management and interchange.

This second edition cancels and replaces the first edition (ISO/IEC 19583-21:2022), which has been technically revised.

The main changes are as follows:

• examples have been added to instatiate the metamodel of the latest version of the ISO/IEC 11179 series (Annexes B and C have been added).

A list of all parts in the ISO/IEC 19583 series can be found on the ISO and IEC websites.

Introduction

The ISO/IEC 11179 series^[1] provides a specification for a registry in which information about metadata can be recorded and maintained.

The metamodel to instantiate such a registry is expressed in text as a conceptual model. This conceptual model is illustrated with a series of diagrams which use the class diagram notation from the Unified Modeling Language (UML).^[2][3]

Implementers and users of the registries described in ISO/IEC 11179 require further guidance to turn the conceptual models into concrete instantiations. This document provides a possible instantiation of the registry metamodel specified in ISO/IEC 11179-3 ^[4], ISO/IEC 11179-31 ^[5] and ISO/IEC 11179-32 ^[6] using the SQL database language as specified in the ISO/IEC 9075 series.^[7]

This specimen instantiation is provided to increase the understanding of ISO/IEC 11179-3, ISO/IEC 11179-31 and ISO/IEC 11179-32, and hence, to promote its adoption.

This document is not intended to replace the UML version but rather serves as a complement, providing SQL statements that describe the ISO/IEC 11179 metamodel. It aims to facilitate the application of ISO/IEC 11179 in a database or related environment.
