我无法理解为什么使用此查询无法获得动态和体裁标签:
SELECT DISTINCT ?item ?itemLabel ?value ?inception ?creatorLabel ?image
(group_concat(?genreLabel; separator=", ") AS ?genres)
(group_concat(?movementLabel; separator=", ") AS ?movements)
WHERE {
?item wdt:P4610 ?value;
wdt:P18 ?image. #with an image
OPTIONAL { ?item wdt:P571 ?inception; #optionally with creationdate
wdt:P170 ?creator; #Optionally with creator
wdt:P136 ?genre;
wdt:P135 ?movement.
}
SERVICE wikibase:label { bd:serviceParam wikibase:language "it,[AUTO_LANGUAGE]"}
} GROUP BY ?item ?itemLabel ?image ?value ?inception ?creatorLabel
ORDER BY ?item
我已经尝试了很多方法,但是似乎总是错误的。
