thanks for picking up thus topic. I have to leave in a few minutes for
a 6 week assignment, therefore only just a few words:
- my intention & impression was that - as of now - substance=* is a
tag to be chosen wisely (cough) by whoever needs it, but more
definition & structure is definitely a goal.
- I was thinking of a kind of "main type, sub type" scheme, i.e.
substance=fuel
substance:detailed=kerosine
substance=fuel
substance:detailed=diesel
substance=water
substance:detailed=drinking_water
etc.

Have a good trip. In the mean time ...
More organisation with sub tags as I call them?
At a base physics level substance = solid, liquid, gas .. Don't know if
that level of reduction is needed? And it would need the addition of
slurry anyway! And I don't know of 'multiphase' (as in how to fit it in)?
So for natural gas worked out to that basic level, as one example, that
would be
substance = gas
gas=fuel
fuel=natural_gas
None of this colon/semicolon business that has got people so worked up :)
And it may reduce the errors of tagging things like
substance=fuel
substance:detailed=drinking_water
And it too gets around drinking_water as that becomes
substance = liquid
liquid=water
water=drinking (or potable?)
Other ideas? Kick them around guys.. brainstorm it.
Oh.. 'multiphase' is a mixture of gas, fuel and water as it comes out of
some well heads (as stated on the wiki). Interested to see any ideas on
a good tag for that .. nice puzzle that one. Maybe it is the physics tag
of multiphase as in containg all the states of gas, liquid and solid.
Fits... anyone know?
