[OSM-talk-be] Mapping of motorways - use of int_ref tag on nodes?

[Yves bxl-forever]

Hello,

I came across something fishy:

node
  [int_ref="E 411"]
  (50.792806,4.417019,50.823614,4.481392);
out;


It seems that someone is routinely applying the "int_ref" tag on all individual nodes of motorways.  This seems weird and it duplicates a lot of information, because this is normally already there on the way.

If that is not okay, I’ll try to get in touch with the mapper who did that.
Is anyone familiar with how to map motorways properly?

Thanks.
Yves
