  Note that the axioms for the Pizza class are there but they are not editable. Protégé uses the reasoner even 
  when entering or editing axioms to ensure that any axioms have the proper syntax so since there is no

  incorrect axioms) only delete them using the X at the right of each axiom. 
  
  Also note the panels on the right: Comments and Project Feed. These are new capabilities in Web Protégé 
  to facilitate collaborative design of ontologies. We will demonstrate that shortly. First, you can navigate 
  the class hierarchy by clicking on the triangles at the left of each class that has at least one subclass. This 
  will expand the class and show its subclasses. Click on Pizza to see its subclasses. For our scenario 
  imagine we are opening a new branch of our pizza store in Chicago and we are dealing with a domain 
  expert in Chicago pizza. As they examine the hierarchy, they are appalled to see that there is no class for 
  ChicagoPizza, a type of deep dish Pizza that first became popular in Chicago. Click on NamedPizza. 
  Then click on the icon at the left corner of the Comments view. If you hover the mouse over this icon you
