  • The "PDF2" Plugin is for use with older versions of the toolkit. It produces production quality PDF output using XSL-FO. Note that this plug-in is now shipped as the default PDF processor in the DITA-OT, and it is maintained by Suite Solutions.
  • Music: a sample specialization with README files describing how to set up a plugin. Includes HTML formatting overrides, including localized table headings. Maintained by Robert D Anderson at IBM.
  • Context Sensitive Help specialization, with XHTML overrides and Eclipse CSHelp file generator. Mantained by Jeff Antley at IBM.
  • Docbook2dita - a transform from Docbook to DITA and some proof-of-concept examples of interoperability.
  • Message Specialization; reference specialization for encoding messages. Includes XHTML processing overrides. Contributed by Scott Stark at IBM.
  • FrameMaker adapter from Mekon (Mark Poston) and XMetaL: a transform that creates a single book file from a map that can be imported into FrameMaker for final printing (more information at
  • APIRef Reference specialization and XHTML formatting overrides. Contributed by Erik Hennum at IBM.
  • Java APIRef Reference specialization and XHTML formatting overrides (requires the APIRef plugin). Contributed by Erik Hennum at IBM.
  • The C++ API Reference, contributed by Nokia, contains a set of specializations based on the APIRef package; as you might expect, it is for documenting C++ APIs.
  • Thesaurus plugin: a specialization that defines formal subjects and the relationships between those subjects so you can classify what your content is about. Contains early work for the classification support coming from OASIS in DITA 1.2. Contributed by Erik Hennum at IBM.
  • Troubleshooting specialization and XHTML processing overrides, contributed by Scott Stark at IBM.
  • "Plus" plugins are a drop-in replacement for HTML-based transforms (html, xhtml, htmlhelp, eclipsehelp) with lots of extension points for other plugins to extend.  Contains sample plugins that render equations and syntax diagrams as SVG, can rasterize SVG to bitmaps, add context-sensitive help to HTML Help, and other common tasks. A prebuilt zip file of the plugins can be found at dita-users (see below).
