DITA Open Toolkit

The DITA Open Toolkit, or DITA-OT for short, is an open-source tool that provides processing for OASIS DITA content. See dita-ot.sf.net for documentation, information about releases, and download packages.

Prerequisites

To build and use DITA-OT, you’ll need:

• Java Development Kit 6 or newer

• Apache Ant 1.8.2 or newer

  If Ant throws an error like unknown protocol: plugin or unknown protocol: cfg, your Ant installation may be outdated. Try installing a newer version of Ant.

Building

1. Clone the DITA-OT Git repository:

    git clone git://github.com/dita-ot/dita-ot.git
   

2. In the root directory, compile the Java code:

    ant jar jar.plug-ins
   

3. Add these files into the CLASSPATH environment variable:

   • src/main/lib/icu4j.jar
   • src/main/lib/resolver.jar

4. Install plugins:

    ant -f src/main/integrator.xml
   

Usage

1. Add these files and directories into the CLASSPATH environment variable:

   • src/main/
   • src/main/lib/
   • src/main/lib/dost.jar
   • src/main/lib/xercesImpl.jar
   • src/main/lib/xml-apis.jar
   • src/main/lib/commons-codec-1.4.jar
   • src/main/lib/saxon/saxon9-dom.jar
   • src/main/lib/saxon/saxon9.jar
   • src/main/lib/resolver.jar
   • src/main/lib/icu4j.jar

2. Change the directory to src/main.

3. Run DITA-OT:

    ant [options]
   

   See the documentation for arguments and options.

Distribution

1. In the root directory, compile the Java code:

    ant jar jar.plug-ins
   

2. Add these files and directories into the CLASSPATH environment variable:

   • src/main/
   • src/main/lib/
   • src/main/lib/dost.jar
   • src/main/lib/xercesImpl.jar
   • src/main/lib/xml-apis.jar
   • src/main/lib/commons-codec-1.4.jar
   • src/main/lib/saxon/saxon9-dom.jar
   • src/main/lib/saxon/saxon9.jar
   • src/main/lib/resolver.jar
   • src/main/lib/icu4j.jar

3. Install plugins:

    ant -f src/main/integrator.xml
   

4. Build distribution packages:

    ant dist
   

   Distribution packages are build into the target directory.

   If Ant throws an error like java.lang.OutOfMemoryError: Java heap space, you probably need to increase the maximum Java heap size. One way to do this is to set the ANT_OPTS environment variable to a value like -Xmx1024m.

   For more information on the -Xmx option, see Java SE Documentation.
