Re: [Dbpedia-dutch] Completeness of geo_coordinates_nl.nt

[Dimitris K. <kon...@in...>]

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/...)

Best,
Dimitris
