Map based linking (maplink and move-links)
These two steps work together to create links based on a map and move those links into the referenced topics. The links are created based on hierarchy in the DITA map, the @collection-type attribute, and relationship tables. This step is implemented in XSLT and Java.
The maplink module runs an XSLT program that evaluates the map; it places all the generated links into a single file in the temporary directory. The move-links module then runs a Java program that pushes the generated links into the applicable topics.
