[Tagging] Damage Assessment Tags - Would like feedback on a schema

[Blake Girardot]

I don't know Andreas, do we need to say what kind of event it is?

I would lean toward damage:type=hurricane|earthquake|etc

or event:type=hurricane|earthquake|etc

But this actually brings up an issue that we ran into in Nepal.

How do identify the event (and maybe event type) independent of any of tags.

Because we want to map IDP camps, but we want to associate them to the 
specific event was well.

damage:event=* seems like it is for damage tags only.

unless you think of it as a "damage event", meaning an event that does 
damage. so maybe the key name should be damage_event= in that case.

But that was not what we were thinking when we suggested damage:event, 
we were thinking it meant the event that was associated with the other 
damage tags.

We need to figure out how best to take different types of tags, damage 
tags, camp tags, potential landing zone tags and associate them with a 
disaster event so we can review, revise and remove them later.

Maybe disaster?

disaster=nepal_earthquake_2015
disaster:type=*
disaster:damage=*
etc ?

Regards,
Blake
