SPARQL - Insert data from remote endpoint

不问归期 提交于 2019-11-28 11:33:22
问题 How can i query a remote endpoint (like endpoints of DBPedia or Wikidata) and insert resulting triples in a local graph? So far, i know that there are commands like INSERT, ADD, COPY etc. which can be used for such tasks. What i don't understand is how to address a remote endpoint while updating my local graph. Could someone provide a minimum example or the main steps? I'm using Apache Jena Fuseki v2 on Windows and this is my query so far: PREFIX wdt: <http://www.wikidata.org/prop/direct/>
