无法在 ARC2 中执行任何插入操作

Question

我浏览了varios示例，并试图为ARC2 INSERT。没有任何结果。也许是一些语法错误？

<?php
include_once("./vendor/semsol/arc2/ARC2.php");
  $dbpconfig = array(
  "remote_store_endpoint" => "http://dbpedia.org/sparql",
   );
  $store = ARC2::getRemoteStore($dbpconfig); 
  if ($errs = $store->getErrors()) {
     echo "<h1>getRemoteSotre error<h1>" ;
  }
$query = '
PREFIX untitled-ontology-3: http://.../untitled-ontology-3#>
PREFIX dbpedia-owl: <http://dbpedia.org/ontology/>
  PREFIX owl: <http://www.w3.org/2002/07/owl#>
  PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>
  PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
  PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
  INSERT INTO <http://localhost:8080/proyecto1/data/proveedRDF2.rdf> 
 {untitled-ontology-3#MMM  rfd:type dbpedia-owl:City; 
    ?untitled-ontology-3:nombreLocalidad  rdfs:label ?label .
}';
