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).
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. 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) or the IEC
list of patent declarations received (see https://patents.iec.ch).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see
www.iso.org/iso/foreword.html. In the IEC, see www.iec.ch/understanding-standards.
This document was prepared by Joint Technical Committee ISO/IEC/JTC 1, Information technology,
Subcommittee SC 32, Data management and interchange.
This first edition of ISO/IEC 11179-30 cancels and replaces ISO/IEC TS 11179-30:2019, which has been
technically revised.
The main changes are as follows:
[4]
— removed the prior dependence on ISO/IEC 11179-3 , since this document is intended for use when
a metadata registry is not appropriate;
— reflect the relocation of the metamodel for data specification registration from ISO/IEC 11179-3 to
[5]
ISO/IEC 11179-31 .
A list of all parts in the ISO/IEC 11179 series can be found on the ISO and IEC websites.
Any feedback or questions on this document should be directed to the user’s national standards
body. A complete listing of these bodies can be found at www.iso.org/members.html and

Introduction
Data processing and electronic data interchange rely heavily on accurate, reliable, controllable and
verifiable data recorded in databases. A prerequisite for correct and proper use and interpretation
of data is that both users and owners of data have a common understanding of the meaning and
representation of the data. To facilitate this common understanding, a number of characteristics, or
attributes, of the data have to be defined. These characteristics of data are known as “metadata”, that is,
“data that describe data”. The ISO/IEC 11179 series provides a family of conceptual metamodels for the
attributes of data elements and associated metadata to be specified and registered as metadata items
in a metadata registry (MDR).
This document provides a simplified presentation of the basic attributes which are required to describe
data elements and associated metadata, and which might be used in situations where a complete
ISO/IEC 11179-3 metadata registry is not appropriate (e.g. in the specification of other International
Standards).
This document applies to the definition, specification and contents of collections of metadata, including
interchanging or referencing among such collections.
