Talk:Key:content
content=unknown
When to use content=unknown? Wouldn't it be better not to add the tag until the actual content is surveyed? --Absay (talk) 05:54, 12 March 2017 (UTC)
content=empty
Sometimes a tank might be permanently empty, so maybe add content=empty. Jidanni (talk) 17:50, 7 December 2017 (UTC)
substance
Why "content" if we had substance=*? If we have storage_tank and also pipeline from this tank to farmlands and the water inside both of them - it is the same water in the pipe and the tank and must be tagged in similar way. VlIvYur (talk) 10:43, 27 June 2018 (UTC)
Gases ?
Gases seem a very technical subject.
Finding the difference between LNG, LPG and natural_gas is not easy.
Should we use only gas ?

@Pyrog: It's great that someone wants to cleanup these tags. Please go forward!
- Should we use only gas ?
In most cases you must know the type of gas, it's not visible and difficult to guess. But this is no reason not to map it as specific as possible. Greetings.--N.plath (talk) 21:45, 19 January 2019 (UTC)
