Service Data Objects
There is an article Tackling a Java Challenge With SOA on Service Data Objects on InternetNews. It's interesting that Clint Boulton is one of the few industry commentators covering the Service Data Objects, which has got almost no media or analyst attention to date. Also, not many vendors have implemented the specification.
CodeFutures is actively looking at Service Data Objects. It's difficult to understand the general lack of industry interest.
Is anyone out there using Service Data Objects?
