Assigns unique ID attribute values to all topics in the current file or book.
The format of ID values assigned to topics are defined in the fm2dita.ini file by the IdPrefix and IdType parameters. By default IdPrefix is set to “id” and IdType is “GUID”.
This command should be run before running the other FM2DITA commands to ensure all topics are properly marked. It must be run after the EDD has been applied since it relies on the default class attribute values to identify topic elements (they contain the string “topic/topic”).
