Developing DITA Maps  

DITA maps provide a mechanism for ordering topics and creating a topic hierarchy. Because DITA maps consist of lists of references to topics, you can reorganize the content in a deliverable simply by changing the order of the topic references. You can create different maps referencing the same source topics to create two deliverables to meet different users' needs.
