For the moment, the only document available on this subject has been written in french. I will send it to you personnaly.

The attribut myTerritory seems useless. I suppose you want that your aggregate knows its components, no ? In this case, this is the attribut "components", defined at the level of SpatialEntitySet.

this last instruction should be remove.
The method can be :
buildMunicipeTerritory
self spaceModel
setAggregates: Municipe
from: Cell
attribute: #municipe.
It will construct the Municipe aggregates from the values of attribut municipe of Cell.
Now, if you want that each cell knows its municipe, you can add a method in Cell class :
municipe
^self theCSE at: #Municipe
Best regards,
Pierre
