Thanks a lot for your reply. The data model is the same: https://github.com/iliriani/Test/blob/main/Notebook.rdf
The issue is just that how to get belonging <attribute> of a given <class>? For instance, as I said if I query for the attributes of class "Teacher" I should get the result: - id - Emri - Mbiemri - Lendet - Evaluations - User because the above <attribute> are within the <class> "Teacher".
