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. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
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.
ISO/IEC 23005-7 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.
ISO/IEC 23005 consists of the following parts, under the general title Information technology — Media context
and control:
Part 1: Architecture
Part 2: Control information
Part 3: Sensory information
Part 4: Virtual world object characteristics
Part 5: Data formats for interaction devices
Part 6: Common types and tools
Part 7: Conformance and reference software

ISO/IEC 23005-7:2011(E)
Introduction
This part of ISO/IEC 23005 specifies conformance and reference software. The conformance and reference
software of ISO/IEC 23005 serves three main purposes:
validation of the written specification of the several parts of ISO/IEC 23005;
clarification of the written specification of the several parts of ISO/IEC 23005; and
conformance testing for checking interoperability for the various applications against the reference
software which aims to be compliant with ISO/IEC 23005.
