Hi Steve, Dennis and Emil,

To be able to use the route for further processing, it would be also nice,
if OSRM would return a list of original network link ID's instead of a more
or less simplified route geometry and a few via points.

This is not an issue for distance matrices, where you only need to total
distance or cost, but too much generalized routes was the reason, why I
couldn't make use of OSRM once. And especially if the OSRM routing result
could be later used again in PostgreSQL/PostGIS, having the original road
network ID's would be very helpful.

So far I couldn't find anything else than this JSON output format:
