Wikidata Query Service/User Manual
IMPORTANT: in Wikidata prefixes don't need to be specified explicitly in SPARQL queries. However, in our Wikibase.cloud instance, prefixes must be explicitly stated, as this example shows. Please note and mind the distinction between PREFIX kbwdt, kbwd, wdt and wd.

ISSUE: the Wikidata SPARQL template for query syntax highlighting is not implemented in this Wikibase.
- SOLUTION: Instead one must use a <sparql tryit="1">...</sparql> wrapper, as demonstrated in this example.
IMPORTANT: The exact URL https://kbtestwikibase.wikibase.cloud/wiki/Project:SPARQL/examples, as well as the correct formatting of this page, are important to correctly display these query examples in the query services interface (click the Examples button at the top)
