[OSM-talk] Skip geographical (redundant) address tags

What I do to avoid most redundancy, is to create an associatedStreet
relation. So the house only needs a housenumber and maybe a housename and
all the rest of the information is on the relation. (addr:country, addr:city
and addr:postcode). I add more than one street to them though, even if JOSM
complains about that. I only create a different one for the same street if
this street crosses city limits or when a change of postal code occurs.

There is still some redundancy, since postcode, city and country are
repeated in all these relations, but it's already far better, than to have
that information on each and every house.

Cheers,

Polyglot
