Another update. 

As I now have to use the swisstopo street list for better or worse, I've added the localisation of the street/places/areas to the non-matching object data (the data that you get if you click on the municipality name), for example http://qa.poole.ch/ch-roads/AG/4001.html Clicking on the coordinates will display the location on openstreetmap.org

If you want to fix a difference, please take in to consideration the notes here https://wiki.openstreetmap.org/wiki/OSM_-_GWR_Street_and_Place_Names_Comparison#Important_notes: and don't forget what I mentioned in the previous posting that slight inconsistencies are to be expected.

With other words: "turn brain on" :-)
