[Pellet-users] converting individuals to class ..

[Alan Ruttenberg]

How are instances converted to classes? They mean different things,  
so this has to be a user-defined transform. How are properties  
treated, etc?
I would probably implement this as an explicit translation, with a  
sparql query returning the instances that I am interested in  
converting, and then generating abstract syntax or kb additions  
through the api to generate the new classes and relations.
