        arg:    objective_id (osid.id.Id): the Id of the dependent
                Objective
        arg:    requisite_objective_id (osid.id.Id): the Id of the
                required Objective
        raise:  AlreadyExists - objective_id already mapped to
                requisite_objective_id
        raise:  NotFound - objective_id or requisite_objective_id not
                found
        raise:  NullArgument - objective_id or requisite_objective_id is
                null
        raise:  OperationFailed - unable to complete request
        raise:  PermissionDenied - authorization failure
        compliance: mandatory - This method must be implemented.
