Re: Import of Exiobase data #exiobase
Good with critical questions.
Although Matteo's example is correct, maybe the example would have been easier to understand if using as the second flow "dry mass" as such, rather than "dry mass of steel", the point being that the same flow, namely that of cars has many "balanceable properties" that can each be measured and expressed separately. The flow of car can be expressed by its value (in currency) or its dry mass (in mass units), but also in terms of its material composition, separately reporting its content of steel (in mass units), wood (in mass units), etc. all adding up to the total mass. Each of these baleanceable properties can be balanced across the activity, hence the name, in terms of "what goes in must come out".
So to your specific questions:
In the exiobase hybrid, the cars are reported in currency units,
while the mass specified per material is reported in teh
extensions tables. This is specific to cars, and is of course not
the ideal way to do this. Exiobase is not yet a fully
What Matteo's example says is that the flow of a car with 200 kg
of steel trades at a value of 1000 Euro. Both pieces of
information relates to the same flow and are useful for different
Sector is not in the BONSAI vocabulary. If you mean the same activity and the same flow in different property tables (layers), then yes. The two (and more) balanceable properties can be represented in the same graph, but for balancing you should query only for one specific balanceable property at a time (althoug simultaneous balancing of all balanceable properties is possible).
I hope this helps?
