Using the Class Editor, you can view or edit a class's constraints, documentation, name, notes, or template slot fields.

Class Editor

Any changes you enter into the Class Editor take effect immediately. To make the changes permanent, save the knowledge base by selecting Save from the Project menu. To revert to the last saved version, close Protege-Frames without saving changes. If you have made extensive changes to your knowledge base during the current session, you may wish to save or archive the project before editing classes.

Working with Class Notes

The note icons (windows_class_note.hide, windows_class_note.create, windows_class_note.delete) at the upper right of the Editor allow you work with class sticky notes. These notes, which are not part of your ontology, can be used for todos or communication while you are developing your knowledge base.

  • To hide or show all class notes, click the Hide Class Notes (windows_class_note.hide) button.

  • To create a note for the current class, click the Create Class Note (windows_class_note.create) button.

  • To delete a note from the current class, click the Delete Class Note (windows_class_note.delete) button and then select the note from the list.

For more information, see Working with Notes.

Notes are not available when working with the Editor as a free-standing window.

Changing the Name of a Class

To change the name of a class, edit the name in the Name field. The following rules apply to class names:

  • The name must be a unique frame name in the knowledge base.

  • Class names are case sensitive.

Note: A recommended convention is to make the first character of each word in a class name uppercase and the rest lowercase, and to separate words by underscores.

Changing the Role of a Class

Select the new role from the Role menu. Concrete classes may have direct instances, but do not have to; abstract classes cannot have direct instances. Protege-Frames does not impose any restrictions on the role of your classes.

Changing Constraints

Class constraints are defined programmatically. See Constraints for more information.

Changing Class Documentation

To change the notes for a class, change the text directly in the Class Documentation pane.

Working with Template Slots

The Template Slot buttons at the Template Slots pane allow you to:

For more information about working with slots, see the Slots Table of Contents.

Other Class Editing Operations

Viewing Multiple Classes

To view or edit the information for several classes at once, select the classes one by one and click the View Class (classes_class.view) button to open the Class Editor for every selected class. Opening a new Class Editor does not close the previous editor. This allows you to compare the attributes for two or more classes. Edits can be made directly in any open Class Editor.

Changing Superclasses

To change the superclasses of a class, see: Adding a Superclass, Replacing a Superclass, and Removing a Superclass.
