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. www.iso.org/directives

Introduction
As the exchange of information via the internet and other wired and wire-free networks develops and
expands, the use of XML (Extended Mark-up Language) and its variants continues to grow and develop.
XML will be an important tool in the development and operation of “Intelligent Transport Systems”
(ITS) services.
However, within XML and its variants there are options. In order to obtain maximum benefit,
interoperability and re-use of data within the ITS sector, it is important to implement XML and its
variants in a consistent manner.
This International Standard provides definitions of how to use XML and its variants in a consistent and
interoperable manner within the ITS sector.

INTERNATIONAL STANDARD ISO 24531:2013(E)
Intelligent transport systems — System architecture,
taxonomy and terminology — Using XML in ITS standards,
data registries and data dictionaries
1 Scope
This International Standard assists ITS standards developers and users of ITS standards who wish to
use XML, by providing a consistent definition of the rules and rule references for the use of XML within
ITS systems. This International Standard defines consistent rules and rule references to provide a
framework to be used when implementing XML-based applications in ITS, and particularly in specifying
XML in ITS standards, ITS data registries and ITS data dictionaries. This International Standard also
provides guidance and examples in respect of the use of XML in ITS, and the elaboration of XML within
the ASN.1 data definitions required by ISO 14813-6 and ISO 14817.
NOTE A table of language comparisons (XML, ASN.1, UML) can be found in ISO 14813-6:2009.
2 Conformance
This International Standard prescribes a conceptual model; it does not define any single physical
implementation. It provides a consistent and interoperable means of achieving interoperability for the
international exchange of information in XML application programs. Regional and national XML schema
have the option of providing additional schema and variants for use in local situations.
In order to claim conformance with this International Standard, it is only required to design systems
and exchange data consistently in accordance with the provisions of this International Standard. No
external conformance procedures are proposed or defined in this International Standard, although
regional, national and local implementations are free to, and may choose to, define and require local
conformance procedures.

4 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 14812 and the following apply.
4.1
application
program that reads XML documents and “does something useful” with them
Note 1 to entry: Applications will normally be interfaced to an XML parser, for example via DOM or SAX.
4.2
ASN.1 application
application that uses ASN.1 encodings for communication (except XER)
4.3
ASN.1 schema
definition of the content and structure of data using an ASN.1 type definition
4.4
association end
endpoint of an association, which connects the association to a classifier
4.5
attribute
property of an element
Note 1 to entry: It is additional information about a piece of data (element). Often attributes are used to pass
information about the element and hence can be said to provide metadata for the element. An attribute is a value
indicator (=) and the attribute value is specified within the tag (i.e.
