text: In exercise 2 we set up some parameters regarding new entity names and rendering without much of an 
  explanation. The concept of a*name*in OWL is a little complex so we wanted to wait until you had a basic 
  grasp of an ontology before diving into these details. 
  
  To start with remember that every entity in your ontology has a unique Internationalized Resource 
  Identifier (IRI)9. An IRI is similar to a URL. In fact, a URL is a kind of IRI. I.e., all URLs are IRIs but 
  many IRIs are not URLs. A URL is typically meant to identify a specific page meant to be viewed in a 
  browser. An IRI is often at a smaller level of granularity and for*any*kind of resource, not only those 
  meant to be viewed in a browser. If you go to the Active ontology tab in Protégé you will see the 
  Ontology IRI for your ontology. This is the base IRI that all entities have in common. In addition, each 
  entity has a subsequent part that comes after the base IRI that uniquely identifies the IRI for the entity. 
  
  You can see this by clicking on any entity and starting (but don’t complete) the Refactor>Rename entity 
  command. Click on the Pizza class. Then select Refactor>Rename entity. You will get a pop-up window 
  with the current name: Pizza. However, this is only the final part of the IRI. To see the full IRI click on 
  the check box in the lower right corner that says: Show full IRI. Your full IRI will be different but it will 
  look something like: http://www.semanticweb.org/pizzatutorial/ontologies/2020/PizzaTutorial#Pizza. 
  Uncheck the Show full IRI box and then Cancel the rename command.
