Re: Help with vocabularies to describe transport information

Hi Pieter,

Thanks a lot for your answer! I like the idea of using your proposal for
GTFS vocab. Could you please send me some examples that I could use as a
starting point to create the examples for the DWBP document [1] ? The idea
is to present an example with a timetable in both formats: csv and rdf.

Thanks!
Bernadette
