Great information Jo,
I think it merits a wiki page. Is there already an existing one we can
edit ? I've know your strategy is like this for a long time, and think
it's the best we can do given the circumstances, so we should push this
forward as the de facto standard.
Thanks for the work, glad you are 'back' ;-)

Hi,
I emailed to De Lijn with the question whether it was OK to add this text:
De Lijn
Openstreetmap contains data about public transport with permission
from *De Lijn*, the public transport company in the region of
'Vlaanderen' in Belgium. This permission does not mean Openstreetmap
is endorsed by *De Lijn*. Technical solutions
<https://wiki.openstreetmap.org/wiki/WikiProject_Belgium/De_Lijndata>
are being implemented by Openstreetmap contributors to keep the data
accurate and up-to-date on a best effort basis. There are no
guarantees however that the data is fit for any purpose
to
https://wiki.openstreetmap.org/wiki/Contributors#De_Lijn
They double checked with the legal department and they confirmed it is OK.
On the web site of AGIV, there is also data of De Lijn available, but
as far as I can see, not for the general public.
There is also a mention that if one wants to use it for commercial
purposes, one has to ask De Lijn directly. This involves signing their
standard contract, which I did. In a way it's only a formality, anyone
can do it. Anyway, that's the way to get access to their FTP server.
As far as stops go, we have 8000 which are actually served by buses
left to add. The other 29886 are already available.
Once that data is in OSM, it becomes available under the ODBL. Is OKFN
interested in regular updates of this dataset? Or do you want to put
instructions on your site, how one can download the latest version of
this data with an Overpass query?
Since I started adding them, some contributors have reacted: oh there
is no need to add/edit bus stops anymore. This is not quite true. For
many stops, it's possible to position them either on the shelter or on
the B U S markings which are visible on aerial imagery, for many, many
others, the positions need to be checked in the field.
Some stops have more than 1 ref number. There is only one pole, but
the different divisions (entiteiten/provinces) didn't agree on 1
number. In this case I created 2 nodes next to each other. At the
moment I don't have another way to cope with this problem. (due to
choices for how to store the information efficiently in the DB I use
to compare upstream and downstream data).
The same thing is true when a stop is served by more than one
operator. It's a lot easier to verify in an automated way when there
is one node per operator. Otherwise zone becomes 89;3422 for stops
which are served by De Lijn and Veolia, for example. Or the naming
clashes. Or the route_ref has entries for lines which are unrelated to
De Lijn, so it becomes too hard to verify.
An other problem I encountered is when a tram stop and a bus stop have
the same ref number. In this case I left it on the bus stop and
removed it from the tram stop. There can be only one. (I use these ref
numbers as the common ground between the data of De Lijn and the data
in OSM).
Such stops will always be members of the same stop_area relation.
I'm still working on a way to do QC on the routes. No rest for the
wicked :-)
Kind regards,
Jo

Hi All,
We recieved this email on the okfn-be list from Pieter:
Noël Van Herreweghe of Corvé/Bestuurzaken Flemish government
published a list of datasets that should be open data
according "decreet openbaarheid van bestuur / decreet
hergebruik van overheidsinformatie" and the new policy at the
Flemish Government that databases should be open by default,
not by exception.
If you cannot access a certain dataset in this list:
http://demo.thedatatank.com/flanders/datasets
you should send an email to the responsible organisation. If
the organisation declines you the access to this we can start
a "beroepsprocedure". In all other cases we will have a bunch
of new open data :)
I already did this for Codex Vlaanderen. They first reacted a
bit slow and asked me question about how I wanted the data.
When I got it, I've put it on Github. Right now they are
moving towards a more professional way of opening up their
data. All because just one question.
Conclusion: we need your help! Send a couple of emails, open
Flanders :)
This is also relevant here, the data in this list should be
available as open-data (same licence as CRAB) and there is a lot
of geo-data. A few highlights from that list:
- GRB
- MRB Wegen
- De Lijn routeplanner
- ...
@jo: I you want you can now request full access to the data from
de lijn quoting this "decreet openbaarheid van bestuur / decreet
hergebruik van overheidsinformatie", they should give you the
relevant data including an appropriate licence without you having
to guarantee them . I think this also implies the schedules.
@marc: I see 'Inventaris Bouwkundig Erfgoed' and other relevant
stuff! :-)
If you plan on trying to get a dataset then maybe it's a good idea
to post this on this list. This will prevent duplicate efforts.
I will try and get the GRB/MRB wegen or access to it.
Met vriendelijke groeten,
Best regards,
Ben Abelshausen
