See https://phabricator.wikimedia.org/T116298 The example query I tried (again, just now) is: prefix wd: <http://www.wikidata.org/entity/> prefix wdt: <http://www.wikidata.org/prop/direct/> SELECT DISTINCT ?city WHERE { ?city wdt:P31/wdt:P279* wd:Q515 . # find instances of subclasses of city ?city wdt:P131* wd:Q1202 . # ...located in Saxony. } This will work fine of course if the data is fixed. So if it doesn't time out for you, try it with a data set that is known to contain cycles. -- Daniel Kinzler Senior Software Developer Wikimedia Deutschland Gesellschaft zur Förderung Freien Wissens e.V. _______________________________________________ Wikidata mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikidata
