Template:Articles in

Template documentation

This template is used to generate a partial SPARQL query to filters the results from the language links that are about an item (or a SPARQL variable). You may be looking for {{Articles in wikipedia}} to find if the item has some article in a specific wikipedia language edition instead.

For example the call {{Articles in|?searcheditem|fr}} inside a SPARQL expression will filter the ?searcheditem values to retain only the values for wich wikidata knows a sitelink in french.

SELECT ?item WHERE {
  ?item wdt:P279*/wdt:P31 wd:Q5
     OPTIONAL { ?wartfritem schema:about ?item . ?wartfritem schema:inLanguage "fr" }
     FILTER(bound(?wartfritem))
}
