The OASIS standard for information typing and structured technical documentation.
Darwin Information Typing Architecture (DITA) is an XML-based information architecture and OASIS standard for creating topic-based technical documentation. Originally developed by IBM, DITA is widely adopted in aerospace, defense, healthcare, telecommunications, and enterprise technology sectors — particularly where large-volume technical publication production, localization, and single-source publishing are required.
DITA's core concept is the topic — a discrete unit of information with a single subject (concept, task, or reference). Topics are assembled into publications using DITA maps. Content reuse mechanisms (conrefs, keyrefs, conditions) allow the same content to be delivered across multiple publications without duplication. DITA's structured approach enables reliable component content management, regulated industry traceability, and large-scale localization — capabilities that unstructured authoring tools cannot provide at enterprise scale.
Concept topics (background information), Task topics (procedures), Reference topics (specifications, tables, lists).
DITA maps assembling topics into structured publications; Bookmaps for book-like deliverables.
Conrefs (content references), keyrefs (key-based references), and profiling conditions for multi-variant content delivery.
Domain-specific topic type extensions for regulated industries (pharmaceutical, aerospace, technical manuals).
DITA Open Toolkit (DITA-OT) transformation to HTML5, PDF, EPUB, WebHelp, and DITA-based IETMs.
Component Content Management System integration for enterprise DITA programs (IXIASOFT, Vasont, Astoria).
Templates and implementation resources for DITA/XML are available through the ELDR Institute Knowledge Hub and via direct request.
