A standard licence would of course be a great benefit and I for one have scratched my head after reading all the different terms on which the different GTFS feeds are published wondering which ones I could use for what. I suggest we start sketching out what that licence should look like. I hear the same concerns from operators. I therefore suggest that one of the basic terms should be that the user of the data should be accurately represented the information and should use current data for trip planning purposes etc. The output data should always give an indication of the period for which the timetable was valid. However .... for now we do have enough data for enough places to seed the innovation process (with products like Graphserver/ GoogleTransit etc) to build the 'killer-apps' that will draw the data out of more authorities over time.
