I was thinking of a location observation archetype with GPS coord and altitude, and a power observation archetype with torque, power, cadence etc. I wasn't sure whether they should be grouped like that, or completely separate (power archetype, torque archetype, cadence archetype etc). > The important thing here is the state model of the medical stuff - do you > want to know the exertion level etc at the time of the heart rate - or is it > a parallel measurement that will provide core data for comparison? The results are simultaneously measured by two devices (heart rate through a chest monitor, bike power through a wheel monitor) and recorded on a single master device on the bike, which can later be connected via usb for download. However, some bike setups would measure all this data as two separate independent streams. One could also theoretically add in GPS tracking etc, which is currently not done by the power measuring device (but could be in the future). The coaches want all this data to be combined in various ways (for instance, multiplying heart rate by average power over 15 second windows etc). They would want it to work irrespective of how the data got into the system.. so I want to write some archetypes that are flexible enough to handle the various different measurement devices and combinations of such devices.
