text: This is a revised version of the Protégé 4 Tutorial version 1.3 by Matthew Horridge. Previous versions of 
  the tutorial were developed by Holger Knublauch , Alan Rector , Robert Stevens, Chris Wroe, Simon 
  Jupp, Georgina Moulton, Nick Drummond, and Sebastian Brandt. 
  
  This work was conducted using the Protégé resource, which is supported by grant GM10331601 from the 
  National Institute of General Medical Sciences of the United States National Institutes of Health. 
  
  Chapters 3-5 are based on the original tutorial. I have updated the tutorial to be consistent with Protégé 5. 
  I have also made some changes to address some of the most common issues I’ve seen new users grapple 
  with, to remove some of the dated information about older frame-based versions of Protégé, and various 
  miscellaneous changes. Chapters 6-11 are new. I have added new sections for technologies such as 
  SWRL, SPARQL and SHACL as well as some details on concepts such as IRIs and namespaces. 
  
  Thanks to Matthew Horridge and everyone who worked on the previous tutorials. Special thanks to 
  Lorenz Buehmann who helped me work out a thorny problem as I developed the revised example, to 
  André Wolski for help with the SHACL plugin. Special thanks to Dick Ooms and Colin Pilkington for 
  their excellent detailed feedback on previous versions of the tutorial. Also, thanks to everyone on the 
  Protégé user support email list.
