Currently, classes exist to describe the 'xx student and trainee' and the 'xx student and trainee role' (e.g., “school student or trainee” and “school student or role”), but they describe roles rather than distinct concepts. All these classes are organised under "student and trainee role".
Our suggestion is to obsolete the classes for 'xx student or trainee' and retain the role classes.
The suggested change is also being communicated with the lead of the Population Ontology.
