Let's say I want to find all battlefields of history, and I am only interested in those in Russia (Q159). If I query with P17:Q159 I will get almost none, because most are, rightly, in Soviet Russia (Q18166397) and in the various previous empires of the area, some of whom are bigger than my area of study. Battlefields in Russia is only an example, but this is a rather common need. GeoSPARQL might be a way to enable such queries, if country/region polygons are available and efficiently usable. Thank you for your consideration! :-) TASK DETAIL https://phabricator.wikimedia.org/T204045 EMAIL PREFERENCES https://phabricator.wikimedia.org/settings/panel/emailpreferences/ To: Nicolas_Raoul Cc: Nicolas_Raoul, Lucas_Werkmeister_WMDE, Aklapper, Nandana, Lahi, Gq86, GoranSMilovanovic, QZanden, EBjune, merbst, LawExplorer, _jensen, rosalieper, Jonas, Xmlizer, jkroll, Smalyshev, Wikidata-bugs, Jdouglas, aude, Tobias1984, Manybubbles, Mbch331
