OLS and data tree structure

Question

Hi,
I've a table containing data that are hierarchycally organized and display in an
application as folder and documents.
table listgerm(
id number(5) primary key
lname varchar2(50),
ltype varchar2(10),
pid number(5));
ltype equals to FOLDER or DOC corresponding to folder or document entry.
pid is the parent/ancestor of an id.
it have null if root node.
Here is a "graphical representation" of the folder
B&PD
|-->SEASIA
----|-->VIETNAM
--------|-->BREEDING
------------|-->Doc1
------------|-->Doc2
----|-->PHILIPPINES
--------|-->TRIALS
------------|-->Doc5
------------|-->Doc6
|-->SASIA
|-->INDIA
|-->BREEDING
------------|-->Doc3
------------|-->Doc4
B&PD, SEASIA, SASIA, INDIA, VIETNAM and PHILIPPINES are folders.
B&PD is my root node.
Doc1 to Doc6 are documents.
My goal is to apply OLS on such structure without completely loosing the hierarchical structure.
For OLS, I determined
- one level: Public,
- two compartments: BREEDING and TRIAL,
- and groups based on the location hierarchy.
Here is how I organized label according data structure.
Data | Label
B&PD | Public
|-->SEASIA | Public::SEASIA
----|-->VIETNAM | Public::VIETNAM
--------|-->BREEDING | Public:BREEDING:VIETNAM
------------|-->Doc1 | Public:BREEDING:VIETNAM
------------|-->Doc2 | Public:BREEDING:VIETNAM
----|-->PHILIPPINES | Public::PHILIPPINES
--------|-->TRIALS | Public:TRIAL:PHILIPPINES
------------|-->Doc5 | Public:TRIAL:PHILIPPINES
------------|-->Doc6 | Public:TRIAL:PHILIPPINES
|-->SASIA | Public::SASIA
----|-->INDIA | Public::INDIA
--------|-->BREEDING | Public:BREEDING:INDIA
------------|-->Doc3 | Public:BREEDING:INDIA
------------|-->Doc4 | Public:BREEDING:INDIA
My problem comes when I apply user label.
Suppose I have a user called Paul who need to access all BREEDING data (VIETNAM and INDIA).
So I will give him the following label
Public:BREEDING:VIETNAM,INDIA
He will be able to see everything except the folder SEASIA and SASIA ; breaking the hierarchy.
How can I solve this?
