These ontology tools are in a more preliminary state of development than the other tools of Disciple.
The current ontology of Disciple-RKF/COG was actually developed using the ontology tools of the previous version of Disciple, called Disciple-HPKB, and then automatically translated into the representation of Disciple-RKF/COG.

Change to France, then Revert
Click Apply
Documentation: Another country involved in the war
Explain Hierarchy position, but do not make any change
We would like to add the feature that Paris is the capital.
Before we can do this we need to define Paris in the knowledge base.

19. Select the “Object Hierarchy Browser” workspace and notice the insertion of France_1943
Select “France_1943”
Click “View”
Notice the documentation
Close the object viewer

Click on “Add feature”
The feature browser is opened to allow us to select the feature to be associated to France
Click on “Find”
A “Find feature” pane is opened

24. In the Object Hierarchy Browser
Select “France_1943”
Click on “View”
Notice the presence of the new feature-value pair
Close the viewer
Close the Object Hierarchy Browser

25. Feature editor: hands-on experience
We will now demonstrate the use of the Feature Editor
We want to define a new feature called “has_as_main_cultural_center”
And then use it to state that France_1943 has Paris as its main cultural center

26. In the Disciple Client
Ontology  Feature Browser
The Feature Hierarchy Browser is opened
Expand FEATURE
We inspect the existing features and decide to define the new feature as a sub-feature of “has_as_source_of_strength_and _power”
Click on this feature
Click on View
Notice the domains and the ranges of this feature.
The bounds of the domain and range of the new feature should be less general
In the Feature browser pane click on “New feature”

27. A new workspace is opened to define a sub-feature of “has_as_source_of_strength_and_power”
Type the Name
has_as_main_cultural_center
Apply
Notice that the domain and the range have been updated to show acceptable values (these are the domain and the range of the super-feature)

28. Natural language pattern
The feature to be defined is “Object has_as_main_cultural_center Value”
With this feature, we want to associate the natural language pattern
“Object has Value as its main cultural center”
That is, the feature “France_1943 has_as_main_cultural_center Paris”
Will have the natural language pattern
“France has Paris as its main cultural center”

29. We will now define the domain and the range
We will now define the domain and the range. They will be interpreted by Disciple as upper bound values.
Force is too general a domain
We want the domain to be a state.
We need to look for the subconcept of Force that correspond to state
Click “Add” in the domain pane
A pane with the Object hierarchy browser is opened
Click “Find”
(Error: the Find object pane is not shown)
Reduce the size of the “Modify feature” pane (by clicking on the up arrow at the bottom of the pane) in order to see the Find object pane.
(if we maximize the Feature Editor workspace we can see the “Find objects” pane at the bottom, but we cannot move up the separating bar; in fact, none of the bars can be shifted)
Type
state
In the Find objects pane
Click Find
Several concepts are displayed
Click on “Single_state_force”
Click on “Select”
The Object hierarchy will be expanded to show the selected object.

In the “Browse” pane select a value for the range.
Expand “Strategic_cog_relevant_factor”
Click on “Geographic factor”
Click on “Add to range”
“Geographic_factor” appears in the range pane, preceded by a “+” sign.
