Just a short note about the Transport Hack Day [Open Knowledge Foundation Germany](http://okfn.de/) just ran last week.
We ran the event together with the local transport provider, the Berlin government and the FH Potsdam.
The VBB released GTFS data, opened up their API and provided some geo datasets about entrances to stations.
We had over 120 people registered, lots of them were developers/designers and we had a really inspired atmosphere.
The output in numbers of apps was not as great as we would have liked due to broken datasets and the complicated API, but I think we will see some nice apps in the coming months.
