Hi,
sorry if i continue to ask you about these critical questions but we'd like to
build on OAK a platform that manage over 200M of documents so we'd like to know
in deep how OAK works.
Query Engine
1. I didn't understand how Traverse recovers phisically the graph to
traverse. Is provided in memory ? does it make a search on filesystem or db to
obtain a correct portion of graph and then traverse it ?
2. Can you point out the Traverse classes ? Or unit test?
Instead for RDBMS question i noticed that with our simple class, the first time
i add the node. The second time we obtain an error loading RepositoryImpl.
In detail when MutableTree try to make beforewrite, throw an illegalstate
exception ("this tree does not exist")
Thanks in advance,
best regards

It looks like some RepositoryInitializer is missing (AFAIU, it would take care
of creating the initial content).
Best regards, Julian
