A very interesting topic.
I would have got a humble question.
Will the provisioning of this data base be a centralized provisioning or a
As some may know, I'm thinking about simulated railroads by X3D, and my
question would be:
Assume two countries A and B with two railroad operators, who use such
simulator for international trains moving from A to B or vice versa.
Would the X3D-Earth database be provided by
- railroad operator A
- railroad operator B
- both of them somehow "together"
- a third party
- everyone has an own copy of the whole data base
Just I'm curious (I read that first interest is military interest, but I
wouldn't preclude non-military usage)
