First Edition of ISO/IEC 24754: Minimum Requirements for Specifying
Document Rendering Systems
Secretariat, ISO/IEC JTC 1/SC 34 Announcement

A communication from the JISC Secretariat of ISO/IEC JTC 1/SC 34
announces that the first edition of ISO/IEC 24754 was published on
2008-08-15. "The Secretariat wishes to take this opportunity to thank
the Project editor (Mr. Keisuke KAMIMURA, Dr. Soon-Bum LIM), WG 2
Convener (Dr. Yushi KOMACHI) and all the WG 2 experts who have
participated in the development of this standard. Document ISO/IEC
JTC 1/SC 34 N1057 presents this 'Notice of Publication' for "ISO/IEC
24754:2008, Information Technology -- Document Description and
Processing Languages -- Minimum Requirements for Specifying Document
Rendering Systems." Summary: "When a structured document is interchanged
between an originator and a recipient, the recipient refers to the
style specifications that the originator provides to reconstruct the
presentation. However, when the recipient does not have sufficient
rendering functionality, it may fail to reconstruct the presentation
output as the originator expected. In order to preserve presentation
output in the course of interchange, the originator and recipient need
to negotiate over functionalities referring to the specifications of
document rendering systems. To satisfy this requirement, this standard
provides the minimum requirements for specifying document rendering
systems and document formats. This International Standard can apply to
the document processing environment, where a document is given in a
logically structured format which is expressed by a structure markup
language, and the visual representation of the document is described
by means of the external style and layout specifications which a style
and layout specifications language provides. The visual representation
of the given document is generated when the style and layout
specifications are applied to the logical structure by a document
rendering system. This International Standard provides an abstract list
of the features that a document rendering system may have, thus
providing a frame of reference, against which the user and implementor
can compare the features of a document rendering system. However, this
International Standard does not direct how each document rendering
system should behave. This International Standard provides the minimum
requirements to specify the features that a document rendering system
which transforms formatting objects to rendering output. It may be
used as a frame of reference, against which the user, implementer, or
software agent may compare the features of a document rendering system.
According to these requirements, the user may express what he or she
expects of a document rendering system, the implementer may describe
the functionality and capability of the document rendering system that
he or she implements, and the software agent may negotiate a minimum
set of functionality and capability that are shared across different
document rendering system implementations..."
