In an ideal world one should be able to retrieve Java objects from ozone 
and store them in sO, and vice versa.  I've not looked at Ozone recently, 
so I can't tell you if this is possible or not.   If Ozone objects must 
inherit from a base class, for example, it might be difficult.  sO objects 
have automatically generated helper classes that it uses for storage and 
retrieval.  If Ozone does something similar it may be possible.   The other 
issue is how objects are retrieved.   In the application you are describing 
we need to be able to do a query.   I think this should be handled fine in 
ozone.  It is always possible to map objects between sO and ozone, but it 
might require more than simply retrieving and storing depending on how the 
persistence is managed.
