DITA CMS provides wizards that let you import valid DITA documents into the TEXTML repository.
You can import a document one at a time, or you can import in bulk. Any document you import is automatically assigned to you and assigned the initial status (for example, Authoring:Draft). When you import a map or topic, the map or topic and its dependencies (for example, the map, topics, and images it refers to) are imported into the repository. If one of the document dependencies cannot be found (for example, one of its topic is missing), the import is cancelled and an error message is displayed.
Advanced options also let you control how to handle languages and other attributes as well as duplicate documents.
