SPARQL

Mit der SPARQL Abfragesprache können Sie Graphdaten im RDF-Format durchsuchen. Wir stellen hier einen SPARQL Endpoint für die Bestände ANNO (historische Zeitungen) und AKON (historische Postkarten) zur Verfügung. Wir haben einige Beispiele zusammengestellt und Übersichten der Properties, die als Parameter in der Suche verwendet werden können. Bitte beachten Sie, dass für edm-Properties der Prefix ergänzt werden muss (s. Beispiel).
