osm_point table is populated, but osm_nodes is not.

If that’s important, what should I do about it?

At the moment, I’m trying to extract all the mappable data so that I can compare it with data from other sources and eventually fold everything together into record and pseudo-graph tables (as well as create a map, of course).
