Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
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

Introduction
ISO/IEC 19944-1 provides a data taxonomy, data processing and use categories and other descriptive
facets that can be applied to data. All aspects of ISO/IEC 19944-1 are extensible to meet the needs of
diverse users. The standardized ability to categorize data, describe uses of data and apply other facets
is useful in several scenarios including the application of policy to data and in describing the use of data
to stakeholders.
The aim of this document i
