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

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

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.

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.

INTERNATIONAL STANDARD ISO/IEC 11179-30:2022(E)
Information technology — Metadata registries (MDR) —
Part 30:
Basic attributes of metadata
1 Scope
This document specifies “basic attributes” which are required to describe metadata in situations where
[4]
a complete ISO/IEC 11179-3 metadata registry is not appropriate (e.g. in the specification of other
International Standards).

3.1
object
anything perceivable or conceivable
Note 1 to entry: Objects can be material (e.g. 'engine', 'sheet of paper', 'diamond'), immaterial (e.g. 'conversion
ratio', 'project plan') or imagined (e.g. 'unicorn', 'scientific hypothesis').
[SOURCE: ISO 1087:2019, 3.1.1]
3.2
property
feature of an object (3.1)
EXAMPLE 1 'Being made of wood' as a property of a given 'table'.
EXAMPLE 2 'Belonging to person A' as a property of a given 'pet'.
2
EXAMPLE 3 'Having been formulated by Einstein' as a property of the equation 'E = mc '.
EXAMPLE 4 'Being compassionate' as a property of a given 'person'.
EXAMPLE 5 'Having a given cable' as a property of a given 'computer mouse'.
Note 1 to entry: One or more objects can have the same property.

3.3
characteristic
abstraction of a property (3.2)
EXAMPLE 'Having a cable for connecting with a computer' as a characteristic of the concept 'cord mouse'.
Note 1 to entry: Characteristics are used for describing concepts (3.4).
[SOURCE: ISO 1087:2019, 3.2.1]
3.4
concept
unit of knowledge created by a unique combination of characteristics (3.3)
Note 1 to entry: Concepts are not necessarily bound to particular natural languages. They are, however,
influenced by the social or cultural background which often leads to different categorizations.
Note 2 to entry: A concept is independent of its representation.
[SOURCE: ISO 1087:2019, 3.2.7, modified — Note 2 to entry has been changed]
3.5
attribute
characteristic (3.3) of an object (3.1) or set of objects
[SOURCE: ISO/IEC 11179-3:2022, 3.1.11]
3.6
basic attribute
attribute (3.5) of a metadata item (3.10) commonly needed in its specification
[SOURCE: ISO/IEC 11179-3:2022, 3.2.72, modified — “registry item” has been replaced by “metadata
item” since this document applies to metadata outside the context of a registry.]
3.7
data
reinterpretable representation of information in a formalized manner suitable for communication,
interpretation or processing
Note 1 to entry: Data can be processed by humans or by automatic means.
Note 2 to entry: Data may also be described using the terminological notions defined in ISO 1087 and the
computational notions defined in ISO/IEC 11404:2007. A datum is a designation of a concept with a notion of
equality defined for that concept.
