The DITA Architecture area contains references to specifications and articles that explain the architectural underpinnings of the DITA language.

Introduction to the DITA Architecture

This introduction to the DITA Architecture contains overall technical information about the DITA language and its architecture.

In the DITA architecture, DITA topics are organized by DITA maps. It is also possible to nest sub-topics within a topic. Specialization enables the creation of specialized topics and other units of content that are tailored to particular structural requirements. Content referencing (conref) enables fragments of content to be reused from a single source. Conditional processing permits a single source to support the needs of multiple audiences.

The current version of DITA is specified in the OASIS Darwin Information Typing Architecture (DITA) Standard v1.2. The OASIS DITA Technical Committee is currently working on version 1.3.

The OASIS site http://www.oasis-open.org/specs/index.php#ditav1.2 contains the official versions of the following documents:

Previous versions of the DITA specification

The current DITA specification is version 1.1. This page describes previous versions of the DITA specification.

   Technical work produced by the OASIS DITA Technical Committee includes:

DITA 1.1 versus 1.0

What's new in DITA 1.1:


Version 1.1 of DITA provides enhanced print publishing capabilities with new DITA Bookmap specialization, including extended book metadata. The standard offers more indexing capabilities with new elements for "see" and "see-also" references. It features new elements for defining structured metadata as well as the ability to add new metadata attributes through specialization.

The specification files (HTML and PDF Spec documents, DITA source, DTDs and Schemas) are available here:


The Overview is a great entry point into the various parts of the DITA 1.1 standard:
