anyone got a good idea for the 'magnitude' data type?
-
Do you mean in terms of which unit to assign?
-
ya, i think 'tonnes of tnt' is standard maybe?, but there isnt a freebase data unit type for that.
-
I've created a new Energy unit, "Ton of TNT" that you can use. (I added kiloton and megaton of TNT for good measure.)
One other thing is that, in order to assign a unit, you'll have to change the expected type from floating point range to a plain old float, or create a new range CVT so that you can assign the units to the float properties. (Because the float range type is generic, units can't be assigned to properties it has.)

@spencermountain - you are correct, an explosive charge is measured in 'tonnes of TNT' or 'kilogram of TNT' with regards to blast effect on structures - for example see Table 2.2 on Page 69 of http://books.google.co.uk/books?id=g-L1O4YszQgC.
@jeff - could 'Kilogram of TNT' be added?
-
Since I had already started with the "ton" nomenclature, I added milliton and microton of TNT, which correspond to kilogram and gram respectively.
-
alright!
while we're at it, how bout a megawatt datatype for powerplant?
hey, in one sentence or less, (joke) are freebases datatypes 'semantic? does killoton understand its 1000 times ton?or does each programmer do that stuff adhoc?
cheers guys. thanks.

Gotcher megawatt right here.
Now, whether Freebase's types understand anything or not is an open question. As far as we know, the graph hasn't achieved full sapience yet, but it could just be playing dumb.
If you look at the megawatt type, though, you can see that it has a property "Power in Watts" which can be used to do conversions between units that measure the same dimension (power, energy, length, etc.). There's nothing in Freebase to do this for you at the moment, but the structure is there if anyone wants to make use of it.

Spencermountain - could I provide some suggestions on the fire schema for your base?
Could I suggest adding the 'Disaster' type from skud's Disaster base as an included type? This would ensure that everytime a topic was typed as a fire, it would also be typed as a disaster.
For the 'Buildings Destroyed' property - I think it would be better if the property was named 'Total Number of Buildings Destroyed' which explains clearly that a number is required.
However, I think a couple more properties could be added:
Firstly wildfires don't necessarily destroy buildings, but instead spread over vast areas - could we have a 'Total Area Burnt' which accepts a kilometre squared value?
Also I think it would be good if we could have a 'Notable Structures Burnt' which would allow the buildings/structures burnt to be listed? This would be a property value of 'structure' type from the Architecture Commons.
-
The disaster type now includes a 'Notable structures damaged' property, so the 'Notable Destroyed Structures' property on your 'Fire' type is now redundant, and can be removed.
Same goes for the 'Notable Surviving Structures' property on your 'Fire' type.

ah you're fast! i was just coming here to tell you i pitched your idea tojeff and scud and they dug it

so, thanks. ~

Not fast - just on GMT+4 time!
Good work for noticing that these properties belonged in the disaster type. I didn't spot that.
