text: This tutorial has primarily focused on the desktop version of Protégé because as of this writing Web 
  Protégé doesn’t support any reasoners so the majority of the sophisticated capabilities of OWL and 
  Protégé such as defined classes and SWRL rules can’t be created in Web Protégé. However, one of my 
  goals in creating this tutorial was to address questions that I’ve seen frequently asked on the Protégé user 
  support email list and one of the most common question is the difference between Protégé and Web 
  Protégé. We are all used to using tools as services rather than applications installed on our local 
  machines, so people often go to Web Protégé as their default. While Web Protégé lacks reasoner support 
  it can still be extremely useful for collaborative development. This chapter explains the benefits of Web 
  Protégé and some best practices for using the two tools together. 
  
  To begin it is recommended that new users start with the desktop version of Protégé13. The constraints 
  imposed on the ontology by lack of a reasoner are significant and if one learns only using Web Protégé 
  they will miss many of the benefits of OWL and come away with the idea that Protégé is little more than 
  a traditional object modeling tool. However, once one is familiar with the desktop version it is worth 
  getting familiar with Web Protégé as it can be extremely useful for joint development of an ontology by 2 
  or more people.
