About the DITA 1.1 Specification

The Darwin Information Typing Architecture (DITA) 1.1 specification defines both a) a set of document types for authoring and organizing topic-oriented information; and b) a set of mechanisms for combining and extending document types using a process called specialization.

The specification consists of:

This document is part of the technical specification for the DITA architecture. While the specification does contain some introductory information, it is not intended as an introduction to DITA nor as a users guide. The intended audience of this specification consists of implementers of the DITA standard, including tool developers and specializers.

Changes since DITA 1.0

The DITA 1.1 specification is designed to be backwards-compatible with 1.0-conforming applications. The following major changes to the architecture provide added functionality for 1.1:
  • A <bookmap> specialization for encoding book-specific information in a DITA map
  • A <glossentry> specialization for glossary entries
  • Indexing specializations for see, see-also, page ranges, and sort order
  • Improvements to graphic scaling capability
  • Improved short description flexibility through a new <abstract> element
  • Specialization support for new global attributes, such as conditional processing attributes
  • Support for integration of existing content structures through the <foreign> element
  • Support for new kinds of information and structures through the <data> and <unknown> elements
  • Formalization of conditional processing profiles
