Thank you for the report Vincent, The online data are based on the new to-be-announced release 2015-04
What you found is indeed quite strange as there were no changes in - http://mappings.dbpedia.org/index.php/Mapping_en:Infobox_military_conflict - https://en.wikipedia.org/wiki/Template:Infobox_military_conflict - and from a sample of pages with missing coords I checked there were no substantial changes On the other hand, running a sample extraction of a page returns correct coordinates which complies with the DBpedia Live data http://mappings.dbpedia.org/server/extraction/en/extract?title=Battle_of_Augusta&revid=&format=trix&extractors=custom We will look further into this Best, Dimitris On Mon, Aug 3, 2015 at 10:08 PM, Vincent Malic <vma...@indiana.edu> wrote: > Dear all, > > I've only recently started working with dbpedia as a research resource, so > I apologize in advance if I'm asking a silly question with an obvious > answer.
