2.1.2.2.1 Definition of DITA maps DITA maps are documents that organize topics and other resources into structured collections of information. DITA maps specify hierarchy and the relationships among the topics; they also provide the context in which keys are defined and resolved. DITA maps should have .ditamap file extensions.
2.1.2.2.2 Purpose of DITA maps

2.1.2.2.3 DITA map elements
A DITA map describes the relationships among a set of DITA topics. The DITA map and map group elements organize topics into hierarchies, groups, and relationships; they also define keys.
2.1.2.2.4 DITA map attributes
DITA maps have unique attributes that are designed to control the way that relationships are interpreted for different output purposes. In addition, DITA maps share many metadata and linking attributes with DITA topics.
2.1.2.2.5 Subject scheme maps
