Deleting an Instance

To delete an instance from the knowledge base:

  1. In the Class Relationship pane at the Instances Tab, select the class which contains the instance you want to delete. If the class is not currently displayed, you may need to navigate to it via the class hierarchy. The instances for the selected class are displayed in the Direct Instances pane.
  2. Select the instance you want to delete in the Direct Instances pane. To highlight multiple instances for the same class, hold down the Ctrl key while clicking each class. To highlight a range of instances, click the first instance, then hold down the Shift key and click the last instance in the range.
  3. Click the icon from the instance buttons. You will be prompted for confirmation. 

Once an instance has been deleted it cannot be recovered. 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 instances. To do this, select Save from the Project menu. 

You can also remove an instance value from a slot. This does not remove the instance from the knowledge base. See Instance Fields in the Standard Fields for more information.
