the Protege OWL tutorial will be updated "real soon now". We'll be 
doing OWL 1..1 (there wasn't any point updating before 1.1), but also 
including stuff about data type properties (which can now be reasoned 
over well) and some stuff about instances. finally, there's a whole 
lot of  Protege stuff to change....

I wouldn't, however, hold your breath. Perhaps it will be 
ready  early next year.
