The DITA Technical Committee has announced the publication of the official DITA 1.3 specification which was approved in December. You can get all the details and related publications and files on the OASIS site.
The Darwin Information Typing Architecture (DITA) v1.3 specification defines both a) a set of document types for authoring and organizing topic-oriented information; and b) a set of mechanisms for combining, extending, and constraining document types.
Version 1.3 is organized in three parts called Editions. Each is optimized for a different audience:
- The Base Edition is designed for application developers and users who need only the most fundamental pieces of the DITA framework.
- The Technical Content Edition includes specializations usually used by technical communicators.
- The All Inclusive Edition 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.
