Convert Wiki to DocBook

Why Convert Wiki to DocBook?

Converting Wiki markup to DocBook XML is the path from informal collaborative content to professional-grade technical documentation. DocBook is an OASIS standard XML vocabulary used by the Linux Documentation Project, O'Reilly Media, and numerous enterprise organizations for producing books, manuals, and technical references. When wiki content matures beyond its collaborative origins, DocBook provides the structural rigor needed for publication.

DocBook's semantic XML markup separates content from presentation entirely. Unlike wiki markup that mixes formatting with content, DocBook elements describe what content is (a chapter, a procedure, a warning) rather than how it should look. This separation enables single-source publishing: one DocBook file can generate HTML for web, PDF for print, EPUB for ebooks, and man pages for Unix systems, all from the same source.

The conversion maps wiki elements to their DocBook semantic equivalents: headings become <chapter> and <section> elements, wiki bold maps to <emphasis role="bold">, wiki lists become <itemizedlist> or <orderedlist>, wiki tables become <table> with proper <row> and <entry> elements, and wiki links convert to <link> or <xref> elements. The result is well-formed, schema-valid DocBook XML.

Open source projects and enterprise documentation teams frequently convert wiki-based documentation to DocBook when their projects reach a maturity level that demands professional publication quality. DocBook's rich element set supports features like indexes, glossaries, bibliographies, revision histories, and complex cross-referencing that wiki markup cannot provide.

Key Benefits of Converting Wiki to DocBook:

• Multi-Format Output: Generate HTML, PDF, EPUB, man pages from one DocBook source
• Semantic Structure: XML elements describe content meaning, not appearance
• Schema Validation: RELAX NG schema ensures document correctness
• Professional Publishing: Industry-standard format for technical books and manuals
• Mature Toolchain: Decades of tools including XSLT stylesheets, FOP, and Saxon
• Modular Documents: XInclude for assembling large documents from parts
• Standards Compliance: OASIS standard used by Linux, FreeBSD, and enterprise docs

{| class="wikitable"
|-
! Parameter !! Default !! Description

|-
| debug || false || Enable debug mode
|-
| timeout || 30 || Request timeout (sec)
|}

Output DocBook file (config.xml):

<section>
  <title>Configuration Options</title>
  <table>
    <title>Configuration Parameters</title>
    <tgroup cols="3">
      <thead>
        <row>
          <entry>Parameter</entry>
          <entry>Default</entry>
          <entry>Description</entry>
        </row>
      </thead>
      <tbody>
        <row>
          <entry>port</entry>
          <entry>8080</entry>
          <entry>Server listen port</entry>
        </row>
        ...
      </tbody>
    </tgroup>
  </table>
</section>

Example 3: Wiki Reference with Links

Input Wiki file (api.wiki):

== API Reference ==
The API supports '''REST''' endpoints.

See [[Authentication]] for token setup.

{{Warning|Always use HTTPS in production.}}

Frequently Asked Questions (FAQ)

Q: What is DocBook?

A: DocBook is an XML vocabulary (schema) specifically designed for technical documentation. Originally created in 1991 by HaL Computer Systems and O'Reilly Media, it is now maintained by OASIS as an open standard. DocBook uses semantic XML elements to describe document content (chapters, sections, procedures, warnings, etc.) independently of how the content will be rendered.

Q: What output formats can DocBook produce?

A: DocBook can generate HTML (single page and chunked), PDF (via XSL-FO and Apache FOP or dblatex), EPUB ebooks, Unix man pages, plain text, RTF, and more. The official DocBook XSL stylesheets handle the transformation from XML to each output format. This single-source, multi-format capability is one of DocBook's primary strengths.

Q: How are wiki headings mapped to DocBook elements?

A: Wiki headings are mapped to DocBook's hierarchical structure. Top-level headings (== Heading ==) become <chapter> or <article> elements, while sub-headings (=== Heading ===) become nested <section> elements. This preserves the document hierarchy and enables DocBook features like automatic table of contents and cross-referencing.

Q: Is the resulting DocBook file valid XML?

A: Yes, the converter produces well-formed DocBook 5.x XML that conforms to the OASIS DocBook RELAX NG schema. You can validate the output using any XML validator with the DocBook schema. Well-formed, valid DocBook ensures that the document can be processed by all DocBook-compatible toolchains without errors.

Q: What tools do I need to process DocBook files?

A: For HTML output, you need an XSLT processor (xsltproc, Saxon) with DocBook XSL stylesheets. For PDF, use Apache FOP or dblatex. For EPUB, use the DocBook XSL EPUB3 stylesheet. Pandoc can also read and convert DocBook files. Many Linux distributions include DocBook tools in their package repositories. Online tools like XMLmind also provide DocBook processing.

Q: How are wiki templates converted?

A: Wiki templates like warning boxes, info boxes, and notes are mapped to appropriate DocBook admonition elements (<warning>, <note>, <tip>, <caution>, <important>). Infobox templates are converted to DocBook tables or structured metadata. Templates without clear DocBook equivalents have their content extracted and placed in appropriate paragraph elements.

Q: Can I combine multiple wiki pages into one DocBook book?

A: Yes, you can convert individual wiki pages to DocBook chapters and then assemble them into a complete book using DocBook's XInclude mechanism. Create a master book file with <book> as the root element and use <xi:include> to pull in each chapter file. This modular approach is standard practice for large DocBook documentation projects.

Q: Who uses DocBook for documentation?

A: DocBook is used by the Linux Documentation Project, FreeBSD documentation, GNOME and KDE projects, O'Reilly Media, Red Hat, SUSE, and many enterprise software companies. It is the standard format for Linux kernel documentation, POSIX standards, and many open-source project manuals. Any organization needing professional multi-format technical publishing benefits from DocBook.
