Hi, I was surprised to find that the 2014 version of geo_coordinates_nl.nt only includes triples for 200 articles. In v3.9 there still were triples for about 1200 articles, so what happened to most of these triples? The articles for which the geo coordinates are available also surprised me. They seem to include the geo coordinates in templates that are unmapped. For example: http://nl.wikipedia.org/wiki/Donetsk is included in geo_coordinates_nl.nt, but its infobox is unmapped <http://mappings.dbpedia.org/server/templatestatistics/nl/?template=Infobox_plaats_in_Oekra%C3%AFne>. http://nl.wikipedia.org/wiki/Delft is not included in geo_coordinates_nl.nt, but its geo-properties look correctly mapped <http://mappings.dbpedia.org/index.php/Mapping_nl:Infobox_gemeente_Nederland#naam_inwoner>. My knowledge of the extraction framework is not up-to-date, but this seems to be an issue that can be (easily) resolved. Kind regards, Alex Olieman |

Hi Alex, The total coordinates extracted in Dutch DBpedia are for 296357 distinct resources. Note that coordinates are also found in the mapping based dataset (this are the coordinates that are mapped in the mappings wiki) Also make sure to *not* use the *en_uris* datasets, these are only articles that have a link to an English article and maintain the English uri ( http://dbpedia.org/...)
