Information technology — Concepts and usage of metadata — Part 23: Data element exchange (DEX) for a subset of ISO/IEC 11179-3

This document specifies the message exchange framework for communicating data element definitions with an ISO/IEC 11179-3 metadata registry (MDR). It defines message semantics, protocols and bindings for a set of transactions allowing the exchange of a commonly used subset of data element metadata with an ISO/IEC 11179-3 MDR. This document establishes the following data element message exchange interoperability specifications: — retrieving data element list from an ISO/IEC 11179-3 MDR matching the selection criteria; — retrieving metadata of a selected data element from an ISO/IEC 11179-3 MDR.

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).
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
The ISO/IEC 11179 series addresses the semantics of data, the representation of data, and the
registration of the descriptions of that data, i.e. metadata. While ISO/IEC 11179-3 provides the basic
conceptual model for a metadata registry (MDR) in which information about metadata can be recorded
and maintained, implementers and users of the registries described in the ISO/IEC 11179 series require
further guidance to exchange data element definitions with each other via a standard-based protocol.
It is necessary to have a common protocol and message semantics to be able to communicate with an
MDR to locate the data elements given the search criteria and exchange metadata of data elements by
addressing the technical and semantic interoperability challenges.
This document was developed to describe a message exchange framework specification for
communicating a subset of data element metadata with an ISO/IEC 11179-3 MDR.

4 Overview of data element exchange (DEX) specification
4.1 General
The objective of DEX specification is to describe a message exchange framework for communicating
a subset of administered data element definitions with an ISO/IEC 11179-3 MDR. It defines message
semantics, protocols and bindings for a set of transactions allowing the exchange of a subset of
administered data element metadata with an ISO/IEC 11179-3 MDR.
Two actors are defined as a part of this specification:
— Metadata source: The metadata source is responsible for the creation of the data element list
matching the selection criteria and the creation of metadata for a selected data element per request
from the metadata consumer. The metadata source is associated with an ISO/IEC MDR.
— Metadata consumer: The metadata consumer is responsible for the importation of metadata created
