<p>I'm not sure what you are referring to here.<br>
</p>
<p>Yes the distances are a Produced Work which, if publicly used,
implies that if a Derivative Database was used to produce the
distances that should be made available, but likely this was
unmodified OSM data so no need to actually do that. <br>
</p>
<p>The centroids of the locations of the pupils houses and the
school are clearly a separate database and only serve as inputs to
the routing algorithm, per ODbL 4.5.b only the OSM database
component of a Collective Database used to generate a produced
work needs to be licensed on ODbL terms.</p>
<p>It would seem that this is actually a school book example of when
SA does -not- apply.</p>

<p>PS: from the description it is not even clear if the output was
publicly used to start with.<br>

<br>
I'm sorry to ask an additional question.<br>
<br>
A while ago, I've listened to a talk about navigation of
pupils from their home to the school - it was used to
decide whether the pupil gets a free bus ticket or not.<br>
<br>
The distance calculation was done by a land registry
office, which didn't have a route-able road & path
network, but had trust in the OSM data, since they
inspected it for quite a while. For completeness, they've
used their own housing and school locations, but didn't
use any from OSM.<br>
<br>
They routed from the pupil's house to the school on the
OSM network. Of course, the results were released in
public.<br>
Do such distance calculations also trigger share-alike on
the non-free data (here: schools & houses).<br>
<br>
Regards,<br>
Matthias<br>
