Many thanks Lorenz, I appreciate your support. Yes, I have seen this solution also on SO.
Evaluation and Users are other classes that are part of the "Teacher" class. The "Teacher" is as below: || Teacher | ---------------| || id :int || || Emri: String || || Mbiemri: String || || Lendet: Subject: <class> || || Evaluations: collection[Evaluation] : <class>|| || User: User: <class> || Those all are attributes of the class "Teacher" but differ by their types and may have additional nodes to access them through the SPARQL query.
