Incoming linksI want to detect whether an item is linked to by another item. I originally used:
Use at
- https://query.wikidata.org/sparql
PREFIX wikibase: <http://wikiba.se/ontology#>
PREFIX wd: <http://www.wikidata.org/entity/>
SELECT * WHERE {
VALUES ?x { wd:Q42 }
# N3: It fulfills a structural need, for example: it is needed to make statements made in other items more useful.
BIND(EXISTS { # ?notability3_strong
?statement ?ps ?x .
?other ?p ?statement .
?prop wikibase:claim ?p .
FILTER(?other != ?x)
} AS ?notability3_strong)
}
