Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
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

Introduction
The ability to create, collect, store, maintain, transfer, process and present data to support business
processes in a timely and cost-effective manner requires both an understanding of the characteristics
of the data that determine its quality, and an ability to measure, manage and report on data quality.
ISO 8000 defines characteristics that can be tested by any organization in the data supply chain to
objectively determine conformance of the data to ISO 8000.
ISO 8000 provides frameworks for improving data quality for specific kinds of data. The frameworks
can be used independently or in conjunction with quality management systems.
ISO 8000 covers industrial data quality characteristics throughout the product life cycle from
conception to disposal. ISO 8000 addresses specific kinds of data including, but not limited to, master
data, transaction data and product data.
This document establishes the vocabulary for the ISO 8000 series of parts.
Annex A contains an identifier that unambiguously identifies this document in an open information
system.

the organization
3.3.5
legal entity
physical or juridical person granted legal status by the governing body of a nation, state or community
3.3.6
authoritative identifier
identifier (3.3.1) issued by an organization that is the originator of the object identified or that is a legal
authority
EXAMPLE The original part manufacturer issues the authoritative identifier for that part. Distributors can
also assign identifiers, which are proxy identifiers (3.3.8) (not authoritative identifiers).
Note 1 to entry: An authoritative legal entity identifier (3.3.7) is an authoritative identifier issued by an
organization that is a legal authority.
3.3.7
authoritative legal entity identifier
ALEI
identifier (3.3.1) that identifies a legal entity (3.3.5) and is issued by the administrative agency for a
governing body of the nation, state, or community with the authority to grant legal status
EXAMPLE For the State of Delaware (in the United States), the Division of Corporations is the administrative
agency that issues identifiers for juridical persons represented on documents of formation. This agency issued
the authoritative legal entity identifier “3031657” to identify the formation of the Code Management Association
as a legal entity.
3.3.8
proxy identifier
identifier (3.3.1) issued by an organization that is not the originator of the object identified
3.3.9
proxy legal entity identifier

3.4 Terms relating to measurement
3.4.1
measure
ascertain or determine the magnitude or quantity of something
3.4.2
measurement
result of measuring (3.4.1) something
3.4.3
measurement data
data (3.2.2) representing a measurement (3.4.2)
3.4.4
measurement requirement
textual description of how a criterion is measured (3.4.1), including any necessary additional attributes
and rules to control the test and the element or elements to be tested, and which plays the role of an
external specification for a reliable measuring algorithm
Note 1 to entry: It is important to take care that the measurement requirement does not provide an algorithm
for the measuring process (3.1.1), since it is understood that algorithm development is a competitive arena for
engineering system vendors and where standardization is not possible.
3.5 Terms relating to industrial data
3.5.1
product
thing or substance produced by a natural or artificial process (3.1.1)
[SOURCE: ISO 10303-1:—, 3.1.49]

application protocol
AP
part of ISO 10303 that specifies an application interpreted model satisfying the scope and information
(3.2.1) requirements (3.1.2) for a specific application (3.5.3)

3.5.5
application reference model
ARM
information (3.2.1) model that describes the information requirements (3.1.2) and constraints of an
application (3.5.3) within an application protocol (3.5.4) or module
[SOURCE: ISO 10303-1:—, 3.1.18]
3.6 Terms relating to data dictionary
3.6.1
data dictionary entry
description of an entity (3.3.3) type containing, at a minimum, an unambiguous identifier (3.3.1), a term
and a definition
Note 1 to entry: In the ISO 8000 data (3.2.2) architecture, a property need not be associated with a specific
data type in a data dictionary (3.6.2). The association between a property and a data type can be made in a data
specification (3.6.3).
Note 2 to entry: In order to exchange a value corresponding to a data dictionary entry, more information (3.2.1)
than an identifier, a name and a definition could be needed. For a property, a data type is needed. Depending on
the kind of property, other data elements (e.g. unit of measure, language) could also be needed. These elements
can be given in the data dictionary, in a data specification that references the data dictionary entry, or directly
associated with the data.
Note 3 to entry: In the ISO 13584 data architecture, the dictionary entry for a property is required to reference
a specific data type. Thus, an ISO 13584 dictionary entry is a special case of the more general concept, as it
includes elements of a data specification.
[SOURCE: ISO 22745-2:2010, B.2.17, modified — The spelling of “datatype” has been changed to “data
type” to be consistent with other terms in this document and Note 2 to entry has been modified.]
3.6.2
data dictionary
collection of data dictionary entries (3.6.1) that allows lookup by entity (3.3.3) identifier (3.3.1)
[SOURCE: ISO 22745-2:2010, B.2.16]
3.6.3
data specification
set of requirements (3.1.2) covering the characteristics of data (3.2.2) being fit for one or more particular
purposes
Note 1 to entry: ISO 8000-110 requires a data specification to describe how items belong to a particular class by
using entries from a data dictionary (3.6.2).
Note 2 to entry: In collaborative relationships, the supplier of data and the user of that data agree the content
of the data specification in order to ensure the collaboration will be successful (i.e. the supplier can supply
conforming data and the user is able to exploit the data for the intended purposes).
Note 3 to entry: An effective data specification is one where the creator of the specification intends for the
requirements to be necessary and sufficient for the data to meet the particular purposes.
Note 4 to entry: All stakeholders will be able to understand the data specification more effectively if there is an
explicit statement of the intended purposes for the data.
3.7 Terms relating to characteristic data
3.7.1
property value
instance of a specific value together with an identifier (3.3.1) for a data dictionary entry (3.6.1) that
defines a property
3.7.2
characteristic data
description of an entity (3.3.3) by the class to which it belongs and a set of property values (3.7.1)
EXAMPLE 1 ISO 13584, ISO 15926, ISO 22745, ISO 13399 and ISO/TS 29002 all include characteristic data in
their data (3.2.2) models.
EXAMPLE 2 The item “Hex Cap Screw — A193 Grade B7,.250-20 X 1.250” appears in a manufacturer's
catalogue. It can be described as:
— class: hexagon cap screw;
— property values: [material specification, A193 Grade B7]; [diameter, 0.250 in]; [thread pitch, 20/in]; [length,
1.250 in].
In actual characteristic data, the first element of each bracketed pair would be an identifier (3.3.1) for a data
dictionary entry (3.6.1). The elements are shown decoded here for clarity.
3.8 Terms relating to data quality
3.8.1
data quality
degree to which a set of inherent characteristics of data (3.2.2) fulfils requirements (3.1.2)
Note 1 to entry: See also quality (3.1.3).
3.8.2
data quality management
coordinated activities to direct and control an organization with regard to data quality (3.8.1)
3.8.3
data error
non-fulfilment of a data (3.2.2) requirement (3.1.2)
Note 1 to entry: In this term, “error” is synonymous with nonconformity (3.1.5).
3.8.4
data provenance record
record of the ultimate derivation and passage of a piece of data (3.2.2) through its various owners or
custodians
Note 1 to entry: A data provenance record can include information (3.2.1) about creation, update, transcription,
abstraction, validation (3.8.6), and transferring ownership of data.
3.8.5
verification
confirmation, through the provision of objective evidence (3.2.6), that specified requirements (3.1.2)
have been fulfilled
[SOURCE: ISO 9000:2015, 3.8.12, modified — Notes to entry have been removed.]
3.8.6
validation
confirmation, through the provision of objective evidence (3.2.6), that the requirements (3.1.2) for a
specific intended use or application (3.5.3) have been fulfilled
[SOURCE: ISO 9000:2015, 3.8.13, modified — Notes to entry have been removed.]
6 © ISO 2020 – All rights reserved

3.8.7
authoritative data source
owner of a process (3.1.1) that creates data (3.2.2)
EXAMPLE The Department of Transportation of the Commonwealth of Pennsylvania, USA, is the
authoritative data source for Pennsylvania motor vehicle registration records.
3.8.8
accepted reference value
value that serves as an agreed-upon reference for comparison
Note 1 to entry: The accepted reference value is derived as:
a) a theoretical or established value, based on scientific principles;
b) an assigned or certified value, based on experimental work of some national or international organization;
c) a consensus or certified value, based on collaborative experimental work under the auspices of a scientific or
technical group;
d) the expectation, i.e. the mean of a specified set of measurements (3.4.2), when a), b) and c) are not available.
[SOURCE: ISO 3534-2:2006, 3.2.7]
3.8.9
true value
value that characterizes a characteristic perfectly defined in the conditions that exist when the
characteristic is considered
Note 1 to entry: The true value is a theoretical concept and, in general, cannot be known exactly.
