Thank you. This will give me the bios, however, I still want the associated wikipedia links. Previously someone had given me a query that included the english wikipedia along with another property. You can see it below:
PREFIX wd: <http://www.wikidata.org/entity/> PREFIX wdt: <http://www.wikidata.org/prop/direct/> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX schema: <http://schema.org/> SELECT ?item ?twitter ?article WHERE { ?item wdt:P2002 ?twitter OPTIONAL {?item rdfs:label ?item_label filter (lang(?item_label) = "en") .} ?article schema:about ?item . ?article schema:inLanguage "en" . FILTER (SUBSTR(str(?article), 1, 25) = "https://en.wikipedia.org/";) } ORDER BY ASC (?article) *I tried to take the PREFIX header and this portion to append to some of your queries. * ?article schema:about ?item . ?article schema:inLanguage "en" . FILTER (SUBSTR(str(?article), 1, 25) = "https://en.wikipedia.org/";) *The first one, which seems to be only for 1 record, just as a test seemed to give me an ERROR though:* PREFIX wd: <http://www.wikidata.org/entity/> PREFIX wdt: <http://www.wikidata.org/prop/direct/> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX schema: <http://schema.org/> SELECT * WHERE { <http://www.wikidata.org/entity/Q1652291> <http://schema.org/description> ?o . filter(lang(?o)='en'). ?article schema:about ?item . ?article schema:inLanguage "en" . FILTER (SUBSTR(str(?article), 1, 25) = "https://en.wikipedia.org/";) } *So I assume the other queries like this would not work (would timeout on query.wikidata.org <http://query.wikidata.org> so can't test):* PREFIX wd: <http://www.wikidata.org/entity/> PREFIX wdt: <http://www.wikidata.org/prop/direct/> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX schema: <http://schema.org/> SELECT * WHERE { ?s <http://schema.org/description> ?o . filter(lang(?o)='en'). ?article schema:about ?item . ?article schema:inLanguage "en" . FILTER (SUBSTR(str(?article), 1, 25) = "https://en.wikipedia.org/";) } So am I doing something wrong with these combined queries in the syntax? Thanks in advance again, and the help thus far!
