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 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes 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 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. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
The ISO 14306 series format is an industry focused, high-performance, lightweight, flexible file format
for capturing and repurposing 3D product definition data for visualization to enable collaboration and
validation throughout the extended enterprise. The ISO 14306 series format is capable of being streamed
and contains compression for compact and efficient representation.
The ISO 14306 format file is based upon the JT file format and is stored on disk with a file extension of “.jt”.
This document provides a listing of the terms and definitions and required to understand the ISO 14306 series.
This document also acts as a terminology reference for the development of related standards outside of the
ISO 14306 series.
Annex A contains an identifier that conforms to ISO/IEC 8824-1. The identifier unambiguously identifies this
document in an open information system.

3.1
3D visualization
visual presentation on a screen or another media of graphical and textual three-dimensional representation
of a set of data representing an object, information or results of a computational process in order to facilitate
the understanding of the object, for visual information sharing with users and to assist in decision processes
by a human reviewing the visualized data
3.2
streaming
sequentially loading data from a disk based medium
Note 1 to entry: The motivation for streaming is to more efficiently manage system memory.
Note 2 to entry: Transfer of data in a stream of packets, over the internet on an on-demand basis, where the data is
interpreted in real-time by the application as the data packets arrive.
Note 3 to entry: The motivation for streaming is that the user can begin using or interacting with the data almost
immediately, therefore no waiting for the entire data file(s) to be transferred before starting.
Note 4 to entry: The desired end result of streaming is to deliver only the ISO 14306 data that the user needs, where
