Transitive properties //should// be a-cyclic, but the data on wikidata.org is imperfect, so the query endpoint should be able to cope with the presence of loops. Currently, such loops seem to cause a timeout, causing basic queries like "like me all cities in X" to fail. Example query: SELECT DISTINCT ?city WHERE { ?city wdt:P31/wdt:P279* wd:Q515 . # find instances of subclasses of city ?city wdt:P131* wd:Q1202 . }
