text: 1. Start Protégé. When Protégé opens for the first time each day it puts up a screen of all the available 
  plugins. You can also bring this up at any time by using File>Check for plugins. You won’t need any 
  plugins at this point of the tutorial so just click the Not now button. 
  
  2. The Protégé user-interface consists of several tabs such as Active ontology, Entities, etc. When you 
  start Protégé you should be in the Active Ontology tab. This is for overview information about the entire 
  ontology. Protégé always opens with a new untitled ontology you can start with. Your ontology should 
  have an IRI something like: http://www.semanticweb.org/yourname/ontologies/2020/4/untitled-ontology- 
  27 Edit the name of the ontology (the part after the last “/” in this case untitled-ontology-27) and change it 
  to something like PizzaTutorial. Note: the Pizza ontology IRIs shown below (e.g., figure 4.3) show the 
  IRI after I edited the default that Protégé generated for me. Your IRI will look different and will be based 
  on your name or the name of your organization. 
  
  3. Now you want to save your new ontology. Select File>Save. This should bring up a window that says: 
  Choose a format to use when saving the ‘PizzaTutorial’ ontology. There is a drop down menu of formats 
  to use. The default RDF/XML Syntax should be selected by clicking the OK button. This should bring up 
  the standard dialog your operating system uses for saving files. Navigate to the folder you want to use and 
  then type in the file name, something like Pizza Tutorial and select Save.
