2. Data write/load order for hierarchy fk integrity (parent*Id -> *Id)
I think 2 can be addressed pretty well (of course not 100% fool proof) if the output file is written in the right order.
This is actually not possible to do, ie sorting a graph with loops is NP-hard.
That is why we have the dummy-fks thing, which of course should ONLY be used for a case like this where you are sure that there are no bad fk records.
