The DITA Topics Document Type

The Darwin Information Typing Architecture (DITA) is an XML-based architecture for authoring, producing, and delivering technical information. It divides content into small, self-contained topics that can be reused in different deliverables. The extensibility of DITA permits organizations to define specific information structures and still use standard tools to work with them.

A file is considered to be a DITA topic document when either of the following occurs:

The default schema used for DITA topic documents is located in ${frameworks}/dita/dtd/ditabase.dtd, where ${frameworks} is a subdirectory of the Oxygen XML Author install directory.

The CSS file used for rendering DITA content in Author mode is ${frameworks}/dita/css/dita.css.

The default XML catalog is ${frameworks}/dita/catalog.xml.
