The educator model[1] is straightforward to persist with reference 
stream but it is more complicated with the knowledge model[2] where each 
document should be saved in its own refstream file and loaded at demand, 
otherwise the whole model (educator+knowledge) may become too big and 
slow to save/load. Imagine the activity of a teacher or a learner along 
one school year, a lot of documents will be produced.

I play a bit with DiskProxy so that document referenced in the educator 
model are saved as that, but I suspect it ends all the document model 
are still load at once. Document are a mix of view, model and presenter 
so it makes a lot, and it is not easy to control how far in the tree of 
objects the persistence goes, then other problems arise at realod, like 
disconnected object.
