Exception in thread "main" org.openrdf.rio.UnsupportedRDFormatException: No writer factory available for RDF format N-Quads (mimeTypes=text/x-nquads; ext=nq)
I got the exception with using nquads writer, is it possible to know why the exception happens or how to use nquads writer???
HTTPClient httpClient = runner.getHTTPClient();
DocumentSource source = new HTTPDocumentSource(httpClient,"http://guangyuan.dothome.co.kr");
ByteArrayOutputStream out = new ByteArrayOutputStream();
// TripleHandler handler = new NTriplesWriter(out);
TripleHandler handler = new NQuadsWriter(out);
runner.extract(source, handler);
handler.close();
String n3 = out.toString("UTF-8");
System.out.println(n3);
