The DITA Open Toolkit

The DITA Open Toolkit

The DITA Open Toolkit, or DITA-OT for short, is a set of Java-based, open source tools that provide processing for DITA maps and topic content. You can download the OT and install it for free on your computer to get started with topic-based writing and publishing. Note: while the DITA Standard itself is owned and developed by OASIS, the DITA Open Toolkit is an independent, open source implementation of the standard.
