Hi Gerd,
It doesn't require much code to generate the pseudo roads, so maybe it is something for a special option.
Would be nice, if you preserve this code. Maybe even for all addresses, not only for addr:place? But actually I can extract addresses form OSM sources, parse them, convert to roads and get the same result. Either way, I'm glad, that we have found what works and what has to be avoided.
Although the wiki says that either addr:place or addr:street should be used I see many nodes with both.
IMHO use addr:street and ignore addr:place. Most probably addr:place is incorrectly set instead of addr:city, which you get from other data anyway.
I see no good reason to ignore information when it is easy to use.
Yes, I know the feeling, never refuse free data ;) -- Best regards, Andrzej
