TASK DESCRIPTION
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 .
}
