Related links are links that do not appear in the topic source. These links are automatically generated from DITA Maps.
There are two types of related links:
Hierarchical
Relationship table
Because related links are automatically generated from the DITA Map, they allow the topics to be used in different contexts. Related links are less disruptive to flow than inline links. But it’s still important to make sure that you use them appropriately so that you don’t overwhelmed users with too many links.
A couple of examples of good related links
A topic might include instructions for a command that has a lot of parameters and variables. A relationship should be created in the relationship table between the task and command reference topic.
A task topic might need related links to other task topics. For example, a task about performing a system backup might need to link to a task topic about restoring the system database from a backup.
