If by value object, you mean a set of key-value pairs, just cycle through
the DataObject's value Map, and copy all of those values to another Map or
bean. BeanUtils.copyProperties(dataObject, valueObject)?

Just be sure that you're prepared to handle relationship values in addition
to the primitive types and their wrapped versions.

If you're transfering objects, you're probably not transfering the whole
object graph anyway.
