Hi, for your Brienz example i could say that it is only the missing mappings for the infobox properties that describe the coordinates. Look at the mapping page for the Infobox_Swiss_town: http://mappings.dbpedia.org/index.php/Mapping:Infobox_Swiss_town There are mappings for the following infobox properties: latitude, longitude, lon_deg, lon_min, longs, longEW and lat_sec. The infobox at the Brienz wikipage uses different properties: | lat_d=46|lat_m=45|lat_NS=N|long_d=8|long_m=2|long_EW=E I guess that this is the most common reason for missing coordinates.
