DocBook
Definition
DocBook is a document standard popular for writing large documentation. It was originally created by software companies as a standard for technical documentation. However, since then, it has been adapted to many purposes.
The principle
“The core DocBook standard is the DocBook Document Type Definition (DTD) maintained by the DocBook Technical Committee in OASIS. The DTD defines the vocabulary of content elements that an author can use and how they relate to each other. For example, a book element can contain a title element, any number of para elements for paragraphs, and any number of chapter elements. Using the DTD and XML syntax, authors mark up their text content with tag names enclosed in angle brackets like <chapter>. The markup is similar to HTML, but with more tags and tighter rule” (DocBook XSL: The Complete Guide], retrieved 22:26, 4 June 2007 (MEST).
Docbook is interesting if you have:
- Large quantities of content.
- Structured content.
- Content that needs to be interchanged among otherwise incompatible systems.
- Content that you also want to process with a computer
- Content to be rendered in multiple output forms and versions (HTML, PDF, PS, ...)
One can author docbook with any XML editor (see WYSIWYM), but there exist also near or full WYSIWYG solutions, e.g. FrameMaker.
DocBook can be customized to fit specific user's needs (requires the expertise of an information architect).
In education
Docbook is also used in education, e.g.
- To write documentation and manuals, e.g. the schoolbus Project
- To write course materials, e.g. in the Edukalibre project.

<title>FOREWORD</title>
<para>Free software means software that respects the user's
freedom. It means that users are free to run the programs as they
wish, free to study and change the software (or hire others to do
it for them), free to redistribute copies to others, and free to
publish modified versions. As a consequence, users are free to
share, and form communities to exercise effective control over the
software they use. Free software may also be gratis, zero price,
but this is not always the case.</para>

<title>PREFACE</title>
<para>Free and Open Source Software (FOSS) has grown incredibly in
the past few years. Once considered a hobbyist's toy, FOSS has
grown by leaps and bounds and is now used widely throughout the
world, even in critical environments such as financial systems and
network backbones.</para>

<title>Introduction</title>
<blockquote>
<attribution>David Wheeler</attribution>
<para>Briefly, OSS/FS programs are programs whose licenses give
users the freedom to run the program for any purpose, to study
and modify the program, and to redistribute copies of either the
original or modified program (without having to pay royalties to
previous developers).

<para>The above quotation summarizes the guiding principles of
FOSS - the freedom to use, understand, modify and distribute
software. Seemingly a simple matter, today, these principles can
have a profound impact on the economics and dynamics of the
software industry.</para> [.... ]
