[Open-transport] Open Transport Data tools / webservices

TL;DR  1. Let’s settle on vocabulary, 2. Try to work on a easy api 3. just
forget trying to decide a file format

1. The vocabulary is important
The okfn will be very helpful for this, and it will help to understand

2. It is time for transit data to become ubiquitous

The time is over where transit data was new enough to be an
app/dataviz/analysis on its own. The next step is to have transit data
anywhere. That means  that it should be easy to consume for people that are
not used to transit data. APIs will help to get rapidly working (and if it
is not, there simply will be no transit data in the project). Most APIs
fail to be easy for non-transit experts.

Obviously aiming for a unique API can not work. But I think it is worth
paying more attention to it, and maybe the experience on API can help other
projects. Most API are not designed for easy discovery and consumption.


I believe it is vain trying to find an unique file format : there is
already a very strong contradiction between having a rich format (like
complicated fares, complex routes…) and having a format that is easy to
kickstart (both for an agency as for consumer). There will never be any
converging solution.

Kind regards,
