Definition Measurement

[KathiSchleidt]

-013 According to this definition a model qualifies as a measurement. This is counter-intuitive and practical use of the terms.
measurement and measuring A measurement is the observation of a quantity. Note 1 to entry: The process of collecting a measurement is called measuring.

KS: current definition (from 19101) works for me

[KathiSchleidt]

Pertains to the definition of Measurement as follows: set of operations having the object of determining the value of a quantity [SOURCE: ISO 19101-2:2018, 3.21]

I'm fine with Models also fitting under this definition, as Model results can also be provided with OMS

I agree the definition above (ISO 19101-2:2018, 3.21) covers both, measurement/observation and model, and it would be the 'set of operations' that explains how the 'result' came about. And one could argue that the temperature observed using a liquid-in-glass thermometer is also a model result, because such a thermometer is based on a model describing the thermal expansion of the liquid that is translated to a scale. Nevertheless, the common understanding of 'model' involves somewhat more complex relationships. I strongly recommend to clearly distinguish between measurement/observation and model, but to make it clear that OMS can be applied to model results just as well.
