16.2.1.3 Specifying the base file name for a ditamap
By default, the file name for each DITA map file is the base name of the FrameMaker file from which the map was generated, with extension .ditamap. This is true for both book files and chapter files.
To specify a different base name for a chapter map file, include the following setting in a chapter configuration file filename.ini named for the FrameMaker file (see §33.1.1 Providing configuration files for individual chapters):
; MapName = name to use (without extension) for the chapter ditamap.
Alternatively, you can insert a DITAMapName marker in the FrameMaker file. The content of the DITAMapName marker becomes the base name for the map file, overriding any value specified for MapName.
To specify a different base name for a book map file, in your project configuration file:
; BookMapName = name to use (without extension) for the book ditamap.
You cannot use a marker to override the base name for a book map file.
