The problem with that approach is that every id mus be unique all over the
site. And that is not feasible.

I would also need to save information about the objects path to make shure
it is the correct object.

folder1/
    subject1
    subject2
folder2/
    subject1
    subject3

student1
    subjects = [subject1, subject2]

In this case there is no way to know which "subject1" is the right one.

That I could avoid by using this organisation:

subjects/
    subject1
    subject2
    subject3
students/
    student1
        subjects = [subject1, subject2]
