It also describes how you can help us to - achieve our aims.\\[2pt] - \textbf{For Archive maintainers, Authors, Publishers and - Distributors:}\\ - The project team request that, whenever possible, you include this - article in any of the following: - \begin{itemize} - \item Books about \TeX{} and \LaTeX{}. - \item Instructions for authors on using \LaTeX{}. - \item The printed documentation of CD-ROM collections that contain - \LaTeX. - \item On-line collections that include a significant proportion of - documents encoded in \LaTeX. -\end{itemize} -\end{abstract} - -\section{Outline} - -The purposes of the \LaTeX3 system can be summarized thus: it will -greatly increase the range of documents which can be processed; and it -will provide a flexible interface for typographic designers to easily -specify the formatting of a class of documents. - -The \LaTeX3 Project Team is a small group of volunteers whose aim is -to produce this major new document processing system based on the -principles pioneered by Leslie Lamport in the current \LaTeX. - -The major visible work of the team before 1997 was the development of -the current \emph{standard} version of \LaTeX{}. This was first -released in 1994 and has since then been actively maintained and -enhanced by extensions to that core system. They will continue to -develop and maintain this system, releasing updated versions every six -months and recording these activities in the \LaTeX{} bugs database -(see below). - -Although \LaTeX{} may be distributed freely, the production and -maintenance of the system does require expenditure of reasonably large -sums of money. The \LaTeX3 Project Fund has therefore been set up to -channel money into this work. We know that some users are -aware of this fund as they have already contributed to it---many -thanks to all of them! If you want to know more about how you can -help the project, see Page \pageref{fund}---and thanks in advance for -your generosity in the future. - - -\section{Background} - -With \TeX{}, Knuth designed a formatting system that is able to -produce a large range of documents typeset to extremely high quality -standards. For various reasons (\eg quality, portability, stability -and availability) \TeX{} spread very rapidly and can nowadays be best -described as a world-wide de facto standard for high quality -typesetting. Its use is particularly common in specialized areas, such -as technical documents of various kinds, and for multi-lingual -requirements. - -The \TeX{} system is fully programmable. This allows the development -of high-level user interfaces whose input is processed by \TeX{}'s -interpreter to produce low-level typesetting instructions; these are -input to \TeX{}'s typesetting engine which outputs the format of each -page in a device-independent page-description language. The \LaTeX{} -system is such an interface; it was designed to support the needs of -long documents such as textbooks and manuals. It separates content and -form as much as possible by providing the user with a generic (\ie -logical rather than visual) mark-up interface; this is combined with -style sheets which specify the formatting. - -Recent years have shown that the concepts and approach of \LaTeX{} are -now widely accepted. Indeed, \LaTeX{} has become the standard method -of communicating and publishing documents in many academic -disciplines. This has led to many publishers accepting \LaTeX{} -source for articles and books; and the American Mathematical Society -now provides a \LaTeX{} package making the features of \AmSTeX{} -available to all users of \LaTeX{}. Its use has also spread into many -other commercial and industrial environments, where the technical -qualities of \TeX{} together with the concepts of \LaTeX{} are -considered a powerful combination of great importance to such areas as -corporate documentation and publishing. This has also extended to -on-line publishing using, for example, \PDF{} output incorporating -hypertext and other active areas. - -With the spreading use of \SGML{}-compliant systems (\eg Web-based -publishing using \HTML{} or \XML{}) \TeX{} again is a common choice as -the formatting engine for high quality typeset output: a widely used -such system is {\em The Publisher\/} from ArborText, whilst a more -recent development is the object-oriented document editor Grif. The -latter is used for document processing in a wide range of industrial -applications; it has also been adopted by the Euromath consortium as -the basis of their mathematician's workbench, one of the most advanced -of the emerging project-oriented user environments. Typeset output -from \SGML{}-coded documents in these systems is obtained by -translation into \LaTeX{}, which will therefore soon also be a natural -choice for the output of \DSSSL-compliant systems. - -Because a typical \SGML{} Document Type Definition (DTD) uses concepts -similar to those of \LaTeX{}, the formatting is often implemented by -simply mapping document elements to \LaTeX{} constructs rather than -directly to `raw \TeX'. -This enables the -sophisticated analytical techniques built into the \LaTeX{} -software to be exploited; and it avoids the need to program in \TeX{}. - -\section{Motivation} - -This increase in the range of applications of \LaTeX{} has highlighted -certain limitations of the current system, both for authors of -documents and for designers of formatting styles. - -In addition to the need to extend the variety of classes of document -which can be processed by \LaTeX{}, substantial enhancements are -necessary in, at least, the following areas: - \begin{itemize} - \item - the command syntax (attributes, short references, etc); - \item - the layout specification interface (style design); - \item - the level of robustness (error recovery, omitted tags); - \item - the extendibility (package interface); - \item - the layout specification of tabular material; - \item - the specification and inclusion of graphical material; - \item - the positioning of floating material, and other aspects of page - layout; - \item - the requirements of hypertext systems. - \end{itemize} - - Further analysis of these deficiencies has shown that some of the - problems are to be found in \LaTeX{}'s internal concepts and design. - This project to produce a new version therefore involves thorough - research into the challenges posed by new applications and by the use - of \LaTeX{} as a formatter for a wide range of documents, \eg \SGML{} - documents; on-line \PDF{} documents with hypertext links. - - This will result in a major re-implementation of large parts of the - system. Some of the results of such rethinking of the fundamentals - are already available in Standard \LaTeX{}, notably in the following - areas: - -\begin{itemize} -\item Font declaration and selection; -\item Font and glyph handling within mathematical formulas; -\item Handling multiple font glyph encodings within a document; -\item Allowing multiple input character encodings within a document; -\item A uniform interface for graphics inclusion; -\item Support for coloured text; -\item Building and interfacing new classes and extension packages. -\end{itemize} - - -\section{Description} - -The strengths of the present version of \LaTeX{} are -as follows: - \begin{itemize} - \item excellent standard of typesetting for text, technical -formulas\\ -and tabular material; - \item separation of generic mark-up from visual formatting; - \item ease of use for authors; - \item portability of documents over a wide range of platforms; - \item adaptability to many languages; - \item widespread and free availability; - \item reliable support and maintenance by the \LaTeX3 project team. - \end{itemize} - These will be preserved and in many cases greatly enhanced by the new - version which is being developed to fulfill the following requirements. - \begin{itemize} - \item - It will provide a syntax that allows highly automated translation - from popular \SGML{} DTDs into \LaTeX{} document classes (these - will be provided as standard with the new version). - - The syntax of the new \LaTeX{} user-interface will, for example, - support the \SGML{} concepts of `entity', `attribute' and `short - reference' in such a way that these can be directly linked to the - corresponding \SGML{} features. - - \item - It will support hypertext links and other features required for - on-line structured documents using, for example, \HTML{} and \XML{}. - -\item - It will provide a straightforward style-designer interface to support - both the specification of a wide variety of typographic requirements - and the linking of entities in the generic mark-up of a document to - the desired formatting. These two parts of the design process will - be clearly separated so that it is possible to specify different - layouts for the same DTD. - - The language and syntax of this interface will be as natural as - possible for a typographic designer. As a result, this language - could easily be interfaced to a visually-oriented, menu-driven - specification system. - - This interface will also support \DSSSL{} specifications and - style-sheet concepts such as those used with \HTML{} and \XML{}. - - \item - It will provide an enhanced user-interface that allows expression of - the typesetting requirements from a large range of subject areas. Some - examples are listed here. - - \begin{itemize} - \item The requirements of technical documentation (\eg offset layout,\\ - change bars, etc). - \item The requirements of academic publishing in the humanities\\ - (critical text editions, etc). - \item The requirements of structural formulas in chemistry. - \item Advanced use of the mathematical-typesetting features of \TeX{}. - \item The integration of graphical features, such as shading, - within text. - \item the integration of hypertext and other links in on-line - documents using systems such as \HTML{}, \XML{} and \PDF{}. - - \end{itemize} - - Special care will be taken to ensure that this interface is - extensible: this will be achieved by use of modular designs. - - - \item - It will provide a more robust author-interface. For example, - artificial restrictions on the nesting of commands will be removed. - Error handling will be improved by adding - a more effective, interactive help system. - - \item - It will provide access to arbitrary fonts from any family (such as - the \PS{} and TrueType fonts) including a wide range of fonts for - multi-lingual documents and the specialist glyphs required by - documents in various technical and academic areas. - - \item - The new interfaces will be documented in detail and the - system will provide extensive catalogues of examples, carefully - designed to make the learning time for new users (both designers and - authors) as short as possible. - - \item - The code itself will be thoroughly documented and it will be - designed on modular principles. Thus the system will be easy to - maintain and to enhance. -\end{itemize} - -The resulting new \LaTeX{} will, like the present version, be usable -with any standard \TeX{} system (or whatever replaces it) and so will -be freely available on a wide range of platforms. - - -\section{\LaTeX{} documentation} - -\begingroup -\setlength{\parindent}{0pt} - -A complete description of Standard \LaTeX{} can be found in: -\begin{citations} -\item[\LaTeX: A Document Preparation System] - Leslie Lamport,\\ \AW, 2nd ed, 1994. -\item[The \LaTeX{} Companion] - Goossens, Mittelbach and Samarin,\\ \AW, 1994. -\end{citations} - -A recent addition to the publications closely associated with the -project is: -\begin{citations} -\item[The \LaTeX{} Graphics Companion] - Goossens, Mittelbach and Rahtz,\\ \AW, 1997. -\end{citations} - -This \LaTeX{} distribution comes with documentation on several aspects -of of the system.
