Mathematicians, scientists and engineers who use mathematical notation
have particular typesetting needs which generally have not been met by
available software. The principal problem is typesetting mathematical
symbols in documents, which in the majority of cases is performed
using edit/view cycles as with \LaTeX .  Using such systems neither
equations within mathematical documents, nor emails containing such
notations, can be viewed directly from the authoring system.
Mathematics is a science which depends on the use of complex symbols
in order to describe abstract ideas and the laborious methods used to
exchange ideas is perceived as a barrier to mathematical
communication.

The European Mathematical Trust (\acro{EMT}) was established to
provide a powerful support system for the core of a mathematical
computing environment.  Software has been developed through European
collaboration involving commercial organisations and academic
mathematicians in France, Germany, Portugal, Denmark, Sweden, Eire,
Slovakia and the \acro{UK}.  The product is the Euromath system, an
\acro{SGML} based, \acro{WYSIWYG}, mathematical editor, based on the
Grif \acro{SGML} editor.

The current version of Euromath (Em1) is Unix based and has three
Document Type Definitions (\acro{DTD}s which determine the structure
of documents) for creating articles, sheets and slides (\acro{OHP}s).
All include the facility to manipulate \acro{WYSIWYG} mathematics
without an editing/previewing cycle.  Further \acro{DTD}s, including
letter and fax, are scheduled for future releases.

The incorporation of \LaTeX\ to \acro{SGML} conversion software for
mathematics allows notation to be created in either of two ways.  The
appropriate symbols may be selected from symbol palettes, or if the
author is already familiar with \LaTeX , the notation may be typed in
as a \LaTeX\ string and converted to \acro{WYSIWYG} SGML using a
preset key combination.  The equation will be seen as it will appear
in the document and edited using either method.  Similarly certain
\LaTeX\ documents containing mathematics can be converted on input to
\acro{SGML} and edited in a \acro{WYSIWYG} fashion.

Standard features of the editor include automatic updating and
numbering, search and replace facilities, European
(\acro{ISO}-Latin~1) language support, graphics inclusion (\acro{X}11
bitmaps, xwd, Idraw, \acro{EPSF}, \acro{CGM} and \acro{TIFF}) and
\acro{WYSIWYG} generation of commutative diagrams.

The Euromath software package includes a Gopher interface and
automated on-line access to remote databases. Software which helps the
user to create new \acro{DTD}s, and to link the editor to other
applications is also incorporated in the Euromath package.

Subsequent releases will include a \acro{PC} platform, an integrated
mailing system, an extended help system, extra \acro{DTD}s,
development of the directory services and an interface to computer
algebra systems through the related OpenMath project.

The Euromath project has been funded by the European Union Science
programme.  The European Mathematical Trust is a registered charity,
financially based in the \acro{UK}. The editor is available to
academic sites by subscription to Euromath. The current release is the
first stage of a unified computer based \acro{WYSIWYG} mathematical
environment.
