Topics are the main building blocks in DITA
In a DITA-based workflow, authors commonly create topics that answer a focused reader need. A DITA map references those topics and organizes them into a publication or another collection. The same topic can be referenced by several maps without making a separate copy for each deliverable.
The OASIS DITA technical content specification defines familiar information types, including:
- Generic topic: A general-purpose structure for information that does not need a more specific type.
- Concept: An explanation that helps a reader understand a subject, product feature, or underlying idea.
- Task: A procedure organized around an outcome, with steps and supporting information.
- Reference: Information intended for lookup, such as parameters, commands, or specifications.
- Troubleshooting: Information that connects a condition or symptom with possible causes and remedies.
These are useful examples rather than an exhaustive inventory of everything DITA can represent. Choose a type because it fits the information and helps the reader. A task should still explain prerequisites and results where needed; a reference topic should remain understandable without requiring readers to reconstruct the author’s original document.
