ISQ Base Quantity[edit]
@Toni 001: Is it not problematic that we're modelling these quantities as subclass of (P279) ISQ base quantity (Q30337748)? For example, distance (Q126017) is currently a subclass of this quantity, and so inherits that superclass. --SilentSpike (talk) 11:33, 28 May 2020 (UTC)
- Hello @SilentSpike: That's an interesting question. I understand it like this: A quantity A being a subclass of a quantity B means that A and B are basically the same, but that A has some conditions attached which B does not have. For instance, radius, which is a subclass of length, is basically a length restricted to some geometric context. One could say that measuring a radius means measuring a base quantity.

- @Toni 001: Hmm, your understanding is right and you've convinced me that it does still make sense for these quantities. The "true" base quantities can still be obtained by querying for only the direct children of Q30337748. --SilentSpike (talk) 11:12, 4 June 2020 (UTC)
