Now we have :

tag			value			uses
earthquake:damage	collapsed_building	1,499
fixme:building		collapsed		1,492
building		collapsed		787
earthquake_damage	collapsed		2

Time for harmonization ?

"earthquake_damage" should obviously be "earthquake:damage".

"fixme:building=collapsed" looks like it should be
"earthquake:damage=collapsed_building" - but maybe there is a reason for
"fixme" that I'm not aware of.

"earthquake:damage=collapsed_building" is the ITHACA way. Should we
convert all the "building=collapsed" to it ? I would say yes, because
"collapsed" is not a type of building but a building attribute - the
ITHACA way is semantically superior.

If no one is depending on "fixme:building=collapsed" or
"building=collapsed" then I'll convert them. Does the map rendering of
collapsed buildings such as http://zvenzzon.mine.nu:81/map.html
understand "earthquake:damage=collapsed_building" ? Considering the
number of icons represented, it would appear so.
