Hierarchical Linking in DITA Maps
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.
Note: Publishing scripts determine when and how to create hierarchical links. The
@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:
- Right-click the topic and choose
Edit Properties. The
Edit Properties dialog box is displayed. - In the Attributes tab, select the appropriate value from the Collection type drop-down list.
- You can use the Other attributes table to add a value to the
@linkingattribute.
