DocBook is a document format that is specified in a document type definition (DTD) available for SGML and XML . It is particularly suitable for the creation of books, articles and documentation in a technical environment ( hardware or software ). DocBook is an open standard maintained by the Organization for the Advancement of Structured Information Standards (OASIS).

The most widespread use of DocBook is in open source projects. The Linux Documentation Project uses the DTD to create the Howtos . KDE and GNOME / GTK + use it as the basic format for all API documentation and user manuals for application programs .

A comparison between DocBook and the Darwin Information Typing Architecture (DITA) provided for similar purposes can be found there in the section Advantages and Comparison to DocBook .

Sample code

<book id="einfaches_buch">
    <title>Ein sehr einfaches Buch</title>
    <chapter id="einfaches_kapitel">
        <para>Hallo Welt!</para>
