DITA is both a markup language and architecture for defining new markup languages, or creating DITA-compatible flavours of existing languages. Can DITA be specialized to support the S1000D standard, enabling standardized content reuse, integration, and publishing with S1000D-compatible content in a DITA-compliant toolset? If it can, then a strong reuse and integration relationship would become possible between the two standards, with sharable infrastructure, content, and publishing streams. 

The Lone-DITA site (http://www.lone-dita.com) aims to help small documentation teams and small/medium organizations to evaluate and implement DITA. The main feature of the site is a comprehesive tutorial that will guide users through the all major stages necessary to create technical documents using DITA and the DITA Open Toolkit.

DITA Infocenter (www.ditainfocenter.com) is a demonstration of online Eclipse Help that contains the DITA Language and Architectural Specifications (v1.0) and the 1.3.1 version of the DITA Open Toolkit User Guide, all in a single, searchable interface with  a TOC and Index.

When the v1.1 DITA Specs are approved, they too will be included.
