This is really great. I am thrilled about this because this isn't coverage about Wikidata but coverage _with_ Wikidata on major news sites for the second time this week ( http://www.faz.net/aktuell/feuilleton/kino/academy-awards-die-oscars-von-19… being the other one). They're using Wikidata data to do meaningful reporting. Our data and the project as a whole got (at the very least) good enough for this. It feels to me like we've broken through a wall. High5 everyone! :D Cheers Lydia -- Lydia Pintscher - http://about.me/lydia.pintscher Product Manager for Wikidata Wikimedia Deutschland e.V.

Depends how good the DBpedia data really is - as the BBC article says, some 2007 football match in the UK was extracted as a "Battle"... On Wed, Mar 2, 2016 at 1:54 PM Daniel Kinzler <daniel.kinzler(a)wikimedia.de> wrote:

We have bad data too. Until very recently, a number of suburbs of South London had P31 = battle, for no apparent reason. (Presumably, because a parameter hadn't been updated in a script being used to extract from templates or a category). Battles (I think) are something that haven't been extracted very systematically -- I was hoping for better coverage, because quite a lot of the maps in the British Library georeferencing project are maps of battlefields, but I found it wasn't very good. (Another problem even then is that really I would have needed the extent of the battlefield, rather than just central co-ordinates, and that information is currently almost totally lacking). Had Freebase done much extraction of battlefield info? I do rather agree with Gerard and Tom, that I had hoped the Freebase migration would have brought with it rather more of the information extractable from Wikipedia categories. -- James.

They did some, e.g. Military Conflict data extracted from Wikipedia Infoboxes, April 24 2012 <https://www.freebase.com/m/0jbcvt2> (which also shows the type of detailed provenance info they keep for bulk data loads). There are 5,581 battles <https://www.freebase.com/queryeditor?lang=%2Flang%2Fen&q=%5B%7B%22id%22%3Anull%2C%22name%22%3Anull%2C%22type%22%3A%22%2Fmilitary%2Fbattle%22%2C%22%2Fmilitary%2Fmilitary_conflict%2Flocations%22%3A%5B%7B%22id%22%3Anull%2C%22name%22%3Anull%2C%22%2Flocation%2Flocation%2Fgeolocation%22%3A%7B%22type%22%3A%22%2Flocation%2Fgeocode%22%2C%22longitude%22%3Anull%2C%22latitude%22%3Anull%2C%22elevation%22%3Anull%7D%7D%5D%2C%22%2Ftime%2Fevent%2Fstart_date%22%3Anull%2C%22%2Ftime%2Fevent%2Fend_date%22%3Anull%2C%22return%22%3A%22count%22%7D%5D> (a subset of the 10,529 military conflicts <https://www.freebase.com/queryeditor?lang=%2Flang%2Fen&q=%5B%7B%22id%22%3Anull%2C%22name%22%3Anull%2C%22type%22%3A%22%2Fmilitary%2Fmilitary_conflict%22%2C%22%2Fmilitary%2Fmilitary_conflict%2Flocations%22%3A%5B%7B%22id%22%3Anull%2C%22name%22%3Anull%2C%22%2Flocation%2Flocation%2Fgeolocation%22%3A%7B%22type%22%3A%22%2Flocation%2Fgeocode%22%2C%22longitude%22%3Anull%2C%22latitude%22%3Anull%2C%22elevation%22%3Anull%7D%7D%5D%2C%22%2Ftime%2Fevent%2Fstart_date%22%3Anull%2C%22%2Ftime%2Fevent%2Fend_date%22%3Anull%2C%22return%22%3A%22count%22%7D%5D>). There's a list of all the military conflicts available here <https://www.freebase.com/military/military_conflict?instances=>, but now that Freebase is read-only there isn't an easy way to generate a table of dates & locations through the GUI, so some (a tiny bit) of programming would be required to extract the info.

I remember seeing a question from someone asking about dates-of-battles a few months ago; I don't know if it was related to this. One issue that came up in the discussion is that a lot of battles don't have a "date" - instead, they have a "start date" and "end date". (This is more of an issue in the last couple of centuries; not many older battles lasted more than a day). It looks like they've managed to cope with this - for example, their system picked up https://www.wikidata.org/wiki/Q911448 which has start and end - but it's a good reminder that eg/ looking for "date" may not always tell you quite what you expect on the first glance :-) Andrew.
