示例1: job

// We don't really care if the indexing level is in the incorrect graph
//
void Nepomuk2::updateIndexingLevel(const QUrl& uri, int level)
{
QString uriN3 = Soprano::Node::resourceToN3( uri );
QString query = QString::fromLatin1("select ?g ?l where { graph ?g { %1 kext:indexingLevel ?l . } }")

// Practically, this should never happen, but still
