DocBook

markup language for technical documentation. DocBook was originally intended for authoring technical documents relating to computer hardware and software but it can be used for any other sort of documentation. It is maintained and standardized by the DocBook Technical Committee at OASIS (originally SGML Open).

DocBook exists as both an SGML and an XML DTD. DocBook originally started as an SGML application, but an equivalent XML application was developed and has now replaced the SGML one for most uses. (The XML DTD started not with a version 1 but with Version 4.)

DocBook is widely used. Examples include the Linux Documentation Project, the GNOME and GTK+ API references, and the Linux kernel documentation. The Solaris Operating Environment manpages are generated from documents using a DTD based on DocBook.

Norman Walsh and the DocBook Open Repository development team maintain a set of DSSSL and XSL stylesheets for generating print/PDF and HTML output from DocBook documents (as well as generating other formats, including man pages and HTML Help). Walsh is also the principal author of the book DocBook: The Definitive Guide, the official documentation of DocBook. This book is available online under the GFDL, and also as a print publication.
