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. Oxygen XML Editor plugin provides schema driven (DTD, RNG, XSD) templates for DITA documents.

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

• the root element name is one of the following: concept, task, reference, dita, topic
• PUBLIC ID of the document is one of the PUBLIC ID's for the elements above
• the root element of the file has an attribute named DITAArchVersion attribute from the "http://dita.oasis-open.org/architecture/2005/" namespace. This enhanced case of matching is only applied when the Enable DTD processing option from the Document Type Association preferences page. is enabled.

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 Editor plugin 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.
