We even don't have a full implementation yet, not to speak of 
documentation ;-)

fine!

You can start by having a look at Travis prototype implementation, 
studying the JDORI by SUN and by studying the OJB ODMG implementation to 
learn how an object transaction manager can be build with OJB.

Of course you are invited to participate in our discussions and to 
contribute ideas and code !
