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 or
www.iec.ch/members_experts/refdocs).
ISO and IEC draw attention to the possibility that the implementation of this document may involve the
use of (a) patent(s). ISO and IEC take 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 and IEC
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 and https://patents.iec.ch. ISO and IEC 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
constitute an endorsement.

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.
This second edition cancels and replaces the first edition (ISO/IEC 23093-4:2020), which has been
technically revised.
The main changes are as follows:
— modification of introduction;
— addition of new APIs;
— addition of binary reference software and its conformance streams.

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 support transaction tokens to access
valuable functionalities, resources, and data from media things.
Information related to media things 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 input and output data formats for media things such as media sensors, actuators,
storage, and analysers. In addition, media analysers can process sensed data from media sensors to
produce analysed data, and the media analysers can be cascaded to extract semantic information.
This document contains the conformance and reference software implementing ISO/IEC 23093-3,
which includes the tools to describe data exchanged between media things and their APIs.
