Removing a Slot From a Class

You can remove a slot from a class without deleting it from the knowledge base. To do this:

  1. In the Class Relationship pane, select the class which has the slot you want to remove. The slots for the class will be displayed in the Template Slots pane. Note that the slot must be a direct slot for the class; you may not remove an inherited slot. 
  2. Highlight the slot you wish to remove in the Template Slots pane.  
  3. Click the Remove Template Slot button. The slot no longer appears among the slots for the class. The slot is also removed from any subclasses of the class.

To remove several slots at once:

  1. In the Class Relationship pane, select the class which has the slot you want to remove.  
  2. Highlight the slots you wish to remove in the Template Slots pane. To highlight multiple slots, hold down the Ctrl key while clicking each slot. To highlight a range of slots, click the first slot, then hold down the Shift key and click the last slot in the range.
  3. Click the Remove Template Slot button. The slots no longer appear among the slots for the class. The slots are also removed from any subclasses of the class.

Removing a slot cannot be undone. However, if you close Protégé-2000 without saving changes, you will revert to the last saved version. If you have made extensive changes to your project during the current session, you may wish to save before deleting slots. To do this, select Save from the Project menu. 

You can also delete a slot from the entire knowledge base using the Slots tab. See Deleting a Slot for more information.
