DITA Open Toolkit Architecture
DITA Open Toolkit is an open-source implementation of the OASIS specification for the Darwin Information
Typing Architecture. The toolkit uses Ant, XSLT, and Java to transform DITA content (maps and topics) into different
deliverable formats.
Processing structure Map-first preprocessing DITA-OT 3.0 provides a map-first preprocessing option as an alternative to the default preprocess operation. The method, which was introduced in DITA-OT 2.5 as an experimental feature, has been improved and is ready for use in many production scenarios. Map-first-preprocessing provides the same functionality as the default preprocess, but takes a different approach. Processing modules Processing order Store API – Processing in memory Pre-processing modules preprocess target calls the entire set of steps.HTML-based processing modules PDF processing modules PDF (formerly known as PDF2 ) transformation process runs the pre-processing routine and follows it by a series of additional targets. These steps work together to create a merged set of content, convert the merged content to XSL-FO, and then format the XSL-FO file to PDF.
