In addition to the broader-narrower hierarchical relation and the default non-hierarchical relation, concepts can be linked with custom relations.
Custom relations can be imported together with the thesaurus definition or created by project users.
Custom relations are managed in the Custom elements tab of the Resources panel which is located in the Resources tab of the project dashboard.
To open the Custom elements tab:
- Select the Resources tab on the main dashboard toolbar.
- If the concept tree is displayed, turn it off by selecting Toggle custom elements on the toolbar of the Resources panel. The concept tree is replaced by a list of tabs.
- Select the Custom elements tab in the Resources panel.
Custom relations are managed in the homonymous panel of the Custom elements tab.
To create a new custom relation:
- Select Add relation on the right of the panel header.
- If there are no relations already, select Add custom relation in the center of the panel.
The Create custom relation dialog appears.
- Select Single if you want the cardinality of the relation to be one-to-one, select Multi instead if you want the cardinality to be many-to-many.
- Enter the name of the relation in the Label field.
- Enter the URI of the relation in the Uri field.
Optionally choose a group to which the relation will belong from the Group drop-down:
- Type at least two characters in the field. The list of groups whose name matches what you typed will appear below and you can choose the group from the list.
- In any case you can create a new group that will have the name when you typed by selecting Create new group "name" at the bottom.
If you don't choose any group, the relation is placed in a default group.
Optionally enter a description in Description field.
- Select Create.

To edit a relation, select the pencil icon to the right of the relation name. The Edit custom relation dialog appears.
You can check and change the same attributes of the relation that are available when creating a new relation (see above).
Select Save to commit the changes.
