You can use either Ant or the command-line tool to transform DITA content to the
various output formats that are supported by the DITA Open Toolkit (DITA-OT).
DITA-OT transformations
The DITA Open Toolkit (DITA-OT) ships with several core transformations. Each core transformation represents an implementation of all processing that is defined by OASIS in the DITA specification.
Publishing DITA content from Ant
You can use Ant to invoke the DITA Open Toolkit (DITA-OT) and generate output. This is the most robust method of transforming DITA content; you can use the complete set of parameters that are supported by the toolkit.
Publishing DITA content from the command-line tool
The DITA Open Toolkit (DITA-OT) includes a command-line tool designed for users who are unfamiliar with Ant. You can invoke the DITA-OT from the command-line tool and generate output. This method is less robust than Ant.
