This is very important point, but maybe optimistic. I would say that's the last opportunity for JDO to get some traction. In my packet for JDO 2.1 / 3, I would include services around the API like failover, transaction recovery, management and monitoring. I dont't see much things more where JDO could differ from JPA. On the other side JPA has support from big vendors, and in one way or other this is very confortable for short term / long term while JDO is perceived as dead by many. I would love to spend more time on marketing however time is short and market needs to be followed by execution capacity which, for JPOX at least is limited by number of contributors. Regards
