OASIS Launches New DITA XML.org Technical Publishing Community Portal: New Web Site Sponsored by Adobe, Congility, and IBM Brings DITA Users Together to Share Information; 23 April 2018.

DITA version 1.3 was approved as an OASIS Standard. Review details about the new version and download links. See the press release with executive endorsements from Adobe, Cisco, Comtech, IBM, ISIS Papyrus, IXIASOFT, Oracle, PTC, and SDL.

The OASIS DITA TC published a Committee Note entitled "DITA 1.3: Why Three Editions?" on 17 November 2015. To download the Committee Note, please see the announcement from OASIS.

The OASIS DITA TC now sponsors three OASIS TC Open Repository open source projects: dita-lightweight, with content relating to the Lightweight DITA Subcommittee; and dita-rng-converter, providing cross-platform tools for generating DITA-conforming DTD- and XSD-format versions of RELAX NG DITA grammars; dita-stylesheets, featuring style sheets and other resources that can be used to build OASIS-styled publications from DITA source . See the links at OASIS TC Open Projects Sponsored by the Committee.


The purpose of the OASIS DITA Technical Committee (TC) is to define and maintain the Darwin Information Typing Architecture (DITA) and to promote the use of the architecture for creating standard information types and domain-specific markup vocabularies.

DITA is specializable, which allows for the introduction of specific semantics for specific purposes without increasing the size of other DTDs, and which allows the inheritance of shared design and behavior and interchangeability with unspecialized content.

OASIS TC Open Repositories Sponsored by the Committee

Contents of these OASIS TC Open Repositories are created by public contributions under an open source license designated by the DITA TC:

  • dita-specializations - This repository provides storage for DITA specializations that were developed by the DITA TC, but which are no longer part of the DITA standard.
  • dita-lightweight — Schema files, tools and documentation related to the Lightweight DITA Subcommittee
  • dita-stylesheets — Supports development of style sheets and other resources that can be used to build OASIS-styled publications from DITA source
  • dita-rng-converter — Providing cross-platform tools for generating DITA-conforming DTD- and XSD-format versions of RELAX NG DITA grammars: document type shells, vocabulary modules, and constraint modules. It makes it as easy as possible to develop and maintain DITA grammars by allowing use of RELAX NG syntax.

DITA XML.org is a community-driven site hosted by OASIS that provides reliable background information on the standard. The site also serves as a community bulletin board and directory where readers post news, ideas, opinions, and recommendations. It incorporates wiki functionality to let users edit and add new pages to the site. The public is encouraged to contribute content.
