The Darwin Information Typing Architecture (DITA) 1.2 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.
The DITA 1.2 specification consists of the following components:
- Document Type Definitions (DTDs) and XML Schemas (XSDs)
- The DTDs and XSDs – along with the catalog files – define DITA markup for the DITA
vocabulary modules and DITA document types. While the DTDs and XSDs should define the same
DITA elements, the DTDs are normative if there is a discrepancy. If there is a discrepancy between the written specification (this document)
and the DTDs, the written specification takes precedence.
- DITA 1.2 written specification
-
While the DITA 1.2 documentation does contain some introductory information, it is
intended neither as an introduction to DITA nor as a users guide. The intended audience of
this documentation consists of implementers of the DITA standard, including tool developers
and XML architects who develop specializations. The documentation contains several parts:
- Architectural specification
- Language reference
- Conformance statement
- Appendices
The DITA 1.2 written specification is available in the following formats: XHTML, CHM, PDF,
and DITA source. The XHTML version is authoritative.
