If you are using OSM data for routing, you must do some modifications to
obtain routable network with correct topology. I think creating this
routable network from original OSM data means creating Derivative Database,
even if you are not adding any new information into data set. Routable
network based on OSM data contains much more road segments than original

It depends. If they are not adding any data, they can simply point to
the source (planet.osm.org).
If they are adding data, they need to provide the entire derivative
database (4.6.a) or an alteration file (4.6.b) with the new contents.
Based on my experience, I would be surprised if they had non-OSM data in
a derivative database. Far more common is to layer OSM data with other data.
It would be nice if be-on-the-road documented their format and provided
open-source tools to use it, but this is not a legal requirement. The
ODbL is concerned with preserving the openness of the data, not of the
They of course need to meet the other obligations of the ODbL (e.g.
