Summary

Add a means to determine which DeviceMetric relates to which Generic Pressure/Temp?

Description

In some cases a metric does not have a measurement site assigned. Nevetheless, the user (and some algorithms)  need to be able to distinguish between them.

Example:

DeviceMetric (Resource Id: 450) for Ta with DeviceMetric.type.coding.code=150344

DeviceMetric (Resource Id: 451) for Tb with DeviceMetric.type.coding.code=150344


One possible solution would be to use the DeviceMetric.type.text, e.g. set it for DeviceMetric (RId=450) to DeviceMetric.type.text="Ta" and for DeviceMetric(RId=451) to DeviceMetric.type.text="Tb". The DeviceMetric.type.coding.display would be in both cases still the same REF_ID as text,e .g. DeviceMetric.type.coding.display=MDC_TEMP.

One downside is that there is no computable way to determine that the DeviceMetric(RId=451) is the second generic temperature as the tree structure is not preserved due to the upward linking mechanism from DeviceMetric to Device.

For this reason it might be very helpful to introduce an Instance number in the DeviceMetric and potentially also in the Device to allow ordering the sequence of multiple objects in the containment tree with the same type similar to Instance-Number field in 11073-10201.
