They claim <https://www.whosonfirst.org/> 26 million place records. I haven't cloned the data repository <https://github.com/whosonfirst-data/whosonfirst-data> to verify (it's huge). There are 27 place types <https://www.whosonfirst.org/docs/placetypes/#placetypes> (code <https://github.com/whosonfirst/whosonfirst-placetypes/tree/master/placetypes> ). There is a long list <https://www.whosonfirst.org/docs/sources/list/> of sources (code <https://github.com/whosonfirst/whosonfirst-sources/tree/master/sources>), but an incomplete list of concordances <https://www.whosonfirst.org/docs/concordances/>. But as a random example, here are the concordances for Montréal. <https://data.whosonfirst.org/101/736/545/101736545.geojson> "wof:concordances":{ "dbp:id":"Montreal", "fb:id":"en.montreal", "fct:id":"03c06bce-8f76-11e1-848f-cfd5bf3ef515", "gn:id":6077243, "gp:id":3534, "loc:id":"n80132975", "nyt:id":"N59179828586486930801", "qs:id":239659, "qs_pg:id":239659, "tgn:id":7013051, "wd:id":"Q340", "wk:page":"Montreal" } I hope this helps!
