To create hierarchical linking between the topics in a DITA map, you set the appropriate value of the
@collection-type attribute on the map. See the DITA documentation for the meaning of each of the
values of the @collection-type attribute.
@collection-type attribute does not force a particular style of linking.
Instead, it declares what the nature of the relationship is between the topics. The publishing
scripts use that information to determine how to link topics. Scripts for different types of
media might make the determination depending on what is appropriate for the particular type of
media. You can provide additional instructions to the scripts using the
@linking attribute.To add the @collection-type to an item in a map:
Edit Properties. The
Edit Properties dialog box is displayed.@linking attribute.
