Well, that's an interesting question... most of the Charge Point data contributed to the existing websites was done without any clear licensing.
That is an interesting question. The Coulomb Charge Point sites show up on Google Maps now. If you click "more info" you find out what kind of plugs and current are available. However, I don't see the real time data such as whether or not the plug is already in use, etc. which you can find on Coulombs website. You'd think it would be in Coulomb's interest to provide all that data to everyone.
Separately, how do you safeguard against duplication (i.e. the same charging station reported from different sources)?
