Issue 415: Missing inverse of P189

Starting Date: 
Working Group: 

Posted by Robert Sanderson on 5/4/2019

Dear all,

In the 6.2.4 PDF, there isn’t a definition of the inverse property of P189 approximates.  One would imagine P189i is approximated by.

Given that the relationship has a direction (A approximates B), and in Geo this would be between Declarative and Phenomenal Places, this seems like an oversight? Or am I missing something about the relationship that means an inverse is not necessary?

Current Proposal:

Dear All,

It's an oversight indeed!

PLEASE VOTE YES, if you agree with P189 approximates (is approximated by).

Yes, sounds reasonable to me.

In case it wasn’t obvious, a definite YES from me
