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

As you linked to this on the HOT list a few things noticed...


What about the typhoon:, earthquake: or tsunami: tags? Replaced with 
damage:event?

What about e.g. damage:building? This could still be used even if you 
have building= and damage=

What about the status= and impassable= keys and tags?

> Criteria:
> 1. Separate feature/object from damage tag itself
> 2. Identify event the damage tag is related to for analysis and easily
> removing them later
> 3. Allow for assessed and revised indication
> 4. Specify type/source of assessment
> 5. Easy to enter, remember, understand for mappers
> 6. Works well with overpass/overpass-turbo queries
> 7. Relatively easy for routing software to work with
> 8. Most similar to existing OSM tagging schemas
> 9. Allow for initial or revised damage assessment based on ground survey
>
> For any area or node (buildings, amenities, landuse, natural, etc)
> damage=[none | partial | major | destroyed]
> damage:event=event_name[;event_name2;etc]
> damage:assessment=[none | initial | revision]
> damage:organization=organization_adding_damage_tags_name
> source:damage=[satellite | aerial | survey]

> For ways (highways)
> These are the same as above, but we add a damage specific key
> damage:smoothness and use the values from the existing smoothness key
> values (http://wiki.openstreetmap.org/wiki/Key:smoothness). Routing
> software would look for the damage:smoothness=* key and if present use
> that value over the explicit or implicit smoothness=* value. When the
> damage tags are removed, routing would return to pre-event status
> automatically.
> damage=[none | partial | major | destroyed]
> damage:smoothness=[excellent | good | bad | horrible | impassable]
> damage:event=event_name[;event_name2;etc]
> damage:assessment=[none | initial | revision]
> damage:organization=organization_adding_damage_tags_name
> source:damage=[satellite | aerial | survey]
