Are interval-scales in scope for QUDT #342

Open dr-shorthair opened 3 years ago

dr-shorthair commented 3 years ago

Interval scales or coordinates appear to be partly in scope for QUDT, supported by the qudt:conversionOffset property. However, this does require the ability to specify the zero position.

In the well known case of temperature, offsets are specified relative to absolute zero (K) which works because there is a physical basis for the datum. But unclear if this would be supported in QUDT for interval scales like latitude and longitude (degrees north, degrees east) or elevation where the datum is relative to the earth.

Great question. Yes, we'd like to support such things, but as you imply, we will need to think carefully how to do this rigorously and elegantly.
