you will be prompted to create a user ID (your email address) and a password. Once you do that you 
should have a fresh Web Protégé workspace. Figure 12.1 shows what my Web Protégé workspace 
currently looks like. Most of the projects are owned by me although note that the CODO project is owned 
by my colleague Biswanath Dutta. However, I still have complete access to that ontology due to the way 
Biswanath has configured my access as being able to both view and edit the ontology.  
To upload the Pizza ontology, select the large Create New Project button. This will bring up the window 
shown in figure 12.2. Fill out the project name and description, then select the Choose File button and 
navigate to where you have the latest version of the Pizza tutorial with data. Note that in the figure I have

blank. Once you have all the fields set up similar to figure 12.2 click the Create New Project button on 
this dialog (note this is a different button than the one you started from).

main Web Protégé UI to browse an ontology.  
Before you make changes to the ontology you need to make sure the settings for new entities and 
rendering are consistent with the settings you used for the Pizza ontology. The default in Web Protégé as 
with Protégé is to use Auto-Generated UUIDs rather than user supplied names.  If you aren’t sure about 
these settings you can go back to exercise 2 at the beginning of chapter 4 and chapter 7 to refresh your 
memory. There are excellent reasons to use auto-generated UUIDs but for beginners, especially for those 
who want to learn SPARQL, I think they make learning the basics more difficult so we have been using 
the alternative of user supplied names. At the top of the Web Protégé UI in the right corner there are
