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 legth
OSM_ID_2 OSM_ID_1 legth
OSM_ID_3 OSM_ID_2 legth
OSM_ID_2 OSM_ID_3 legth
OSM_ID_3 OSM_ID_4 legth
OSM_ID_4 OSM_ID_3 legth
OSM_ID_2 OSM_ID_4 legth
OSM_ID_2 OSM_ID_4 legth

and 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?

The "Topology" chapter of the workshop is there to explain the basics about the routing network. The first paragraph should actually explain that. If it's not so clear, then I will change this with the next version of the workshop.

But if you import OSM data you just use an import tool named "osm2pgrouting", which is explained in detail a few chapters later: http://workshop.pgrouting.org/chapters/osm2pgrouting.html
