Modelling relationship between lexical entries and spatial regions

Dear ontolex community,

I am currently modelling some data using ontolex and lexinfo. 
However, I have some doubts on how to relate a a lexical entry to a specific spatial area. My intent is to declare that an entry is being used in a specific region in a country or in limited spatial area (a valley, or in a small island for example).

I was wondering if anyone had faced the same challenge and which are the adopted solutions to the problem.

Best,

Nicola
