Management of terminology resources — Terminological markup framework
ISO 16642:2017 specifies a framework for representing data recorded in terminological data collections (TDCs). This framework includes a metamodel and methods for describing specific terminological markup languages (TMLs) expressed in XML. The mechanisms for implementing constraints in a TML are defined, but not the specific constraints for individual TMLs. ISO 16642:2017 is designed to support the development and use of computer applications for terminological data and the exchange of such data between different applications. This document also defines the conditions that allow the data expressed in one TML to be mapped onto another TML.

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 different types
of ISO documents 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes 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 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. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not

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.
This document was prepared by Technical Committee ISO/TC 37, Language and terminology, Subcommittee
SC 3, Management of terminology resources.
This third edition cancels and replaces the second edition (ISO 16642:2017), which has been editorially and
technically revised.
The main changes are as follows:
— The scope is no longer restricted to representing terminological data in XML format. Terminological
markup languages can be serialized in any formats, but they are exemplified in this document in XML.
— DatCatInfo PIDs have been updated.
— Terms and definitions have been updated according to the latest ISO standards.
— Examples have been updated to reflect ISO 30042:2019.
— Appendix A has been significantly revised in order to show two TMF-compliant XML-based serialization
examples of the same terminological data.

Introduction
Terminological data are collected, managed and stored in a wide variety of systems, typically various
kinds of database management systems, ranging from personal computer applications for individual
users to large terminology database systems operated by major companies and governmental agencies.
Terminology databases are comprised of various types of information, called data categories, and can adopt
different structural models. However, terminological data often need to be shared and reused in a number
of applications, and this sharing is facilitated when the data adheres to a common model. To facilitate co-
operation and to prevent duplicate work, it is important to develop standards and guidelines for creating
and using terminological data collections (TDCs) as well as for sharing and exchanging data.
This document presents a modular approach for analyzing existing TDCs and designing new ones. It also
provides a framework for defining terminological markup languages (TMLs) that are interoperable.
This document makes reference to DatCatInfo, an example of an available data category repository (DCR).
DatCatInfo is an online database of information about the types of data that can be included in TDCs and
other language resources. It is available at www.datcatinfo.net.

part of a terminological data collection (3.23) which contains the terminological data related to one concept
3.6
conceptual domain
permissible content of a data category (3.7)
EXAMPLE In a terminology database, the data category /part of speech/ can have a conceptual domain consisting
of the values /noun/, /verb/, /adjective/, /adverb/.
Note 1 to entry: The permissible content can be closed, as in the example, or subject to formal restrictions such as dates,
or free text such as the conceptual domain of /definition/. Although the latter type is not formally restricted, it is
nevertheless subject to adherence to the requirements of its data category specification (3.10), i.e. it contains a true
definition and not a note, example or some other piece of information.

3.7
data category
DC
class of data items that are closely related from a formal or semantic point of view
EXAMPLE /part of speech/, /subject field/, /definition/.
Note 1 to entry: A data category can be viewed as a generalization of the notion of a field in a database.
Note 2 to entry: In running text, such as in this document, data category names are enclosed in forward slashes (e.g. /part
of speech/).
3.8
data category repository
DCR
digital collection of data category specifications (3.10)
EXAMPLE DatCatInfo, a DCR for language resources (see Reference [6 [3]).]).

DC selection
set of data category specifications (3.10) selected from a data category repository (3.8)
Note 1 to entry: A data category selection can represent the data categories (3.7) used within a research discipline or a
specific application or project.
