Introduction to DITA 1.3
The Darwin Information Typing Architecture (DITA) specification defines a set of document types for authoring and organizing topic-oriented information, as well as a set of mechanisms for combining, extending, and constraining document types.

Introduction to DITA 1.3
The Darwin Information Typing Architecture (DITA) specification defines a set of document types for authoring and organizing topic-oriented information, as well as a set of mechanisms for combining, extending, and constraining document types.
- About the DITA specification: All-inclusive edition
  The all-inclusive edition of the DITA specification is the largest edition. It is designed for implementers who want all OASIS-approved specializations, as well as users who develop learning and training materials.
- Terminology
  The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT, "RECOMMEND", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC 2119].
- Normative references
- Non-normative references
  Non-normative references are references to external documents or resources that implementers of DITA might find useful.
- Formatting conventions in the XHTML version of the specification
  Given the size and complexity of the specification, it is not generated as a single XHTML file. Instead, each DITA topic is rendered as a separate XHTML file. The XHTML version of the specification uses certain formatting conventions to aid readers in navigating through the specification and locating material easily: Link previews and navigation links.
- Formatting conventions in the Errata 02 version of the specification
  Content that has been modified since the DITA 1.3 version of the written specification is indicated with visual cues. This document contains changes for both DITA 1.3 Errata 01 and DITA 1.3 Errata 02.
Architectural specification: All-inclusive edition
The architectural specification portion of the DITA specification outlines the framework of DITA. It contains an overview of DITA markup; addressing; processing; configuration, specialization, generalization, and constraints; as well as information about coding DITA grammar files.
Language reference: All-inclusive edition
The language reference portion of the DITA specification contains a topic for each DITA element. The topic defines the element, its inheritance hierarchy, and provides examples of usage. This portion of the DITA specification also includes information about DITA attributes.
Conformance
Conformance to the DITA specification allows documents and document types that are used with different processors or different versions of a processor to produce the same or similar results with little or no reimplementation or modification.
Acknowledgments
(Non-normative) Many members of the OASIS DITA Technical Committee participated in the creation of this specification and are gratefully acknowledged.
Non-normative information
This section contains non-normative information, including topics about new features in DITA 1.3 and migrating from DITA 1.2 to DITA 1.3.
Content models for learning and training package
For each element in the learning and training package, this section presents the content model and a list of parent elements that can contain that element.

Formatting conventions in the Errata 02 version of the specification

Content that has been modified since the DITA 1.3 version of the written specification is indicated with visual cues. This document contains changes for both DITA 1.3 Errata 01 and DITA 1.3 Errata 02.

Added or modified text

The following conventions are used to indicate new topics or text that has been added or modified:

Red text
Red glyphs (sidewise triangles) that surround the modified text

For example, the following screen capture illustrates how a new sentence is displayed:

Note that new topics are not marked with red text or glyphs in the table of contents (TOC).

Deleted text

Content that has been deleted is not displayed. The locations where text has been deleted are not marked with visual indicators. See the Darwin Information Typing Architecture (DITA) Version 1.3 Errata 02 document for a complete listing of changes, including deletions.

Related links

New entries for related links are not displayed with red text or glyphs. See the Darwin Information Typing Architecture (DITA) Version 1.3 Errata 02 document for a complete listing of changes, including the additional related links.
