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)

Yes, it would be better not to tag it. Chrabros (talk) 16:32, 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!

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)
