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 and/or on the ISO list of patent declarations received (see www .iso .org/ patents) or the IEC
list of patent declarations received (see http:// patents .iec .ch).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions 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

This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.

Introduction
The ISO/IEC 23093 series provides an architecture and specifies APIs and compressed representation
of data flowing between media things.
The APIs for the media things facilitate discovering other media things in the network, connecting
and efficiently exchanging data between media things. The APIs also provide means for supporting
transaction tokens in order to access valuable functionalities, resources, and data from media things.
Media things related information consists of characteristics and discovery data, setup information
from a system designer, raw and processed sensed data, and actuation information. The ISO/IEC 23093
series specifies data formats of input and output for media sensors, media actuators, media storages,
media analyzers, etc. Sensed data from media sensors can be processed by media analyzers to produce
analysed data, and the media analyzers can be cascaded in order to extract semantic information.
This document contains the tools to describe data exchanged between media things (e.g. media sensors,
media actuators, media analyzers, media storages) and their APIs. It addresses the normative aspects
of the data and APIs for media things and also illustrates non-normative examples.

Part 4:
Reference software and conformance
1 Scope
This document specifies the conformance and reference software implementing ISO/IEC 23093-3.
The information provided is applicable for determining the reference software modules available for
ISO/IEC 23093-3, understanding the functionality of the available reference software modules, and
utilizing the available reference software modules.
Furthermore, this document provides means for conformance testing, i.e. bitstreams – XML descriptions
– that conform or do not conform to ISO/IEC 23093-3.
