PgRouting Obtain RoadNetwork data from osm file

[المشرف العام]

I am trying to obtain road-network data from OSM file using pgrouting and for this I am following this tutorial:

http://workshop.pgrouting.org/

The format I am looking for is following(bidirectional)

OSM_ID_1 OSM_ID_2 legthOSM_ID_2 OSM_ID_1 legthOSM_ID_3 OSM_ID_2 legthOSM_ID_2 OSM_ID_3 legthOSM_ID_3 OSM_ID_4 legthOSM_ID_4 OSM_ID_3 legthOSM_ID_2 OSM_ID_4 legthOSM_ID_2 OSM_ID_4 legthand so on...

I find that they have missing steps. At the end of this chapter they download the data in form of OSM files.http://workshop.pgrouting.org/chapters/installation.html

Next chapter, they are using data from the "workshop directory":http://workshop.pgrouting.org/chapters/topology.html

I have no idea how the got from one step to another.

Can anyone help me with this?
