Ciao Alessandra, But just using the generic 'related' property would rely on knowing where a certain concept is of class 'treatment' or 'disease', right? We'd need to add that classification to our thesaurus. For academia's sake, how would one do that in SKOS? By using 'broader' terms? How can this then be efficiently queried if I want to find all treatments for a certain disease?
Please be as elaborate as you can, I'm affaid I still have very little traction here...
