Data File Format

The file format (*.osd) is implemented in version 1 and version 2 as plain binary format. Always increasing data sets and therefore data files actual files are compressed. To enable extensibility for a long time period the configuration data are key value pairs. This enables the capability to keep some configuration data optional similar to optional XML elements. The read functions will construct at first a HashMap of the key/values and apply only the values of existing keys. All other are default. Measurement data point are stored without any change as integer values. This enable to have all data files structure the same, there is no difference between devices.
