One of the wonderful things about ODbL is the concept of a collective work as applied to separate databases. Right now, if you were to unofficially screenscrape the UK rail timetable and do magic stuff with it and OSM data, you'd probably fall foul of CC-BY-SA (boo, hiss). Whereas with ODbL it'd be a collective database and OSM wouldn't worry about the fact you don't have permission to do anything at all with the timetable. Not that I'm planning to screenscrape the PDF timetable or anything. Though I imagine that, if I were, I'd use CAM::PDF to read the file, write my own PDF renderer, then parse the columns and put the result in a MySQL database. Purely hypothetically. cheers Richard -- View this message in context: http://www.nabble.com/Is-anyone-making-public-transport-routing-maps-based-on-OpenStreetMap-data--tp21044201p21055443.html Sent from the OpenStreetMap - General mailing list archive at Nabble.com. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

There is not however a problem as far as I know in people collecting their own timetable information from printed material and entering it into a common DV. What would be needed would be a repository and a way of entering data. GTFS is probably a good starting point. Some data is already available from authorities in that format. I do expect that more official data may be donated in time, but people might need to be prepared to do it the hard way first. Personally I also think it would be good to provide a way for people to enter old timetables. I have a bradshaws 1921 railway timetable and there is also a reprint for 1910.

Soundy overly complex compared to just using pdftotext and then parsing the resulting ASCII text, unless of course there's OCR involved which would rule out this approach.

Doesn't preserve the layout, in particular the columns, well enough. The UK rail timetable PDF is composed about as logically as you would expect for our dysfunctional railway system. cheers Richard -- View this message in context: http://www.nabble.com/Is-anyone-making-public-transport-routing-maps-based-on-OpenStreetMap-data--tp21044201p21069208.html Sent from the OpenStreetMap - General mailing list archive at Nabble.com. ___ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk

Personally I am reasonably convinced by the arguments being put forward that any sort of collection of timetable data may be open to challenge within Europe under the DB directive. I notice however that lots of PT data has been released in the USA under freedom of information act which is a curious thing to have to do to find when the buses run. For example http://www.gtfs-data-exchange.com/agency/port-authority-trans-hudson/ I suggest that this is another reason to keen the PT data separate from the OSM data. I was wondering however, if any of the authorities in gtfs-data- exchange would mind their data about the positioning of bus stops to be imported into OSM. Might be worth asking them at some point. The current bus stop positions are sometimes not that accurate in the official data. The data for Davis often puts bus stops in the middle of houses for example.

You can't crowdsource a timetable. You can't crowdsource the future without objective evidence. You can, however, crowdsource what has happened in the past, and use it to make list of when the trains usually used to run. But I have absolutely no interest in an application that says "trains usually ran on a Sunday at 10.35am up until last weekend" because I actually want to go *this* Sunday and I want to know when the trains are *going* to be running, which is in the future and the timetable changed this week[1]. So as far as I'm concerned, the only really useful source of timetables is whoever operates the service.

In my experience, transit agency folks are most concerned by the idea of others disseminating out-of-date/inaccurate information (as well as generally losing control of their "brand"), and ultimately the OSM project should be able to use this to its advantage. You correctly point out that licensing could be a challenge; even the GTFS data that's been intentionally released to the public is generally under custom licenses that were derived from what the other agencies have done. There's real work to be done to find terms that will meet the needs of both OSM and the transit agencies. You could go around making agreements agency-by-agency, but coming up with a standard open transit data license that agencies find palatable is a much juicier point of leverage for changing this world.

Whilst there may be copyright issues in doing this in practice, there is in theory a good reason for having an independent source of timetable data: you could offer web API functionality that the actual rail/bus companies are not offering, which aids the integration of the data into other sites. Also it allows the development of independent train/bus journey planners which the individual companies may not wish to develop themselves.

I'm not arguing that the timetable information shouldn't be made freely available, since I've got every confidence in the power of the crowds to come up with useful and novel things. I'm just saying that in the case of timetables, unlike the geodata that we're familiar with in OSM, I don't think it's crowd-sourceable. Unless we send people one at a time to the ticket office and say "what trains will leave between 10am and 11am this Sunday", note it in a PDA and re-join the back of the queue...
