[Tagging] About new landuses and superiority of cascading tag schemes

[johnw]

There's an interesting question. 

It is a "salt evaporation pond" , and it is a really old practice of making salt. the colorful south bay of san francisco is thanks to salt farming. 

But is refining a mineral really farming? Refining is usually considered industrial - but it was practiced with basically seawater and a flat dirt area for a really long time. 

But now most of the large ones to map are all part of industrial salt refineries.  

Sounds like it would be part of an industrial subtag.
