DITA Map
A DITA map is a hierarchical collection of DITA topics that can be processed to form
            an
            output. Maps do not contain the content of topics, but only references to them. These
            are
            known as topic references. Usually the maps are saved on disk or in a CMS with the
            extension
            .ditamap. 
         
Maps can also contain relationship tables that establish relationships between the topics contained within the map. Relationship tables are also used to generate links in your published document.
You can use your map or bookmap to generate a deliverable using an output type such as XHTML, PDF, HTML Help or Eclipse Help.
