Team's Response

having it as part of code does not necessitate that it is composition. Composition means whole-part but we cannot afford to remove Group, Assignment, etc since they are not whole part and should still persist even if the person model is gone since it is also of another person model's model. So it is not supposed to be presented using composition.

Note that Tag, Comment, Group, Assignment may still exist even after the person is deleted, which forfeits the first condition for composition.
