Types of DITA Documents

Serna supports DITA 1.0 and DITA 1.1 document types, as well as lets you work with DITA specializations.
Note:

Although Serna supports both versions of DITA, DITA 1.0 is obsolescent . We recommend that you create DITA 1.1 documents.

The two main units of authoring in DITA are topics and maps:
  1. DITA Topics

    DITA topics are the basic units of DITA content. Each topic deals with a single subject.

  2. DITA Maps

    DITA maps are documents that collect references to DITA topics to organize them for output to a specific deliverable, including generating navigation files and links to related topics.
