Do you imply that you have real time applications with objects and it ships objects to sensors via Corba? :-) Anyhow if you have a set of sensors, they measure just scalar values, right? I understand that you might want to nest a flat vector of data into objects, as the vector components map into containment hierarchy of the device. Or am I missing anything else?
