Issue 531: Observable Entity
Posted by Martin on 7/03/2021
In the course of elaborating the epistemology of measurement, issue 388,
I propose the following:
Change S15 Observable Entity to superclass of E4 Period, S10 Material Substantial.
Change S21 Measurement to superclass of E16 Measurement.
Change O24 measured (was measured by) to superproperty of P39 measured (was measured by)
Declare O24 measured (was measured by) and O12 has dimension (is dimension of) as top properties of CRMsci.
Declare O12 to be identical with P43 for S10 Material Substantial (and subclasses)
Consider the epistemology of distance measurement, or more generally, comparative measurements, such as distance of two physical features, elevation difference of mountain peaks, two events in space and time.
