    Content
    Dieses DDC-Tool ermöglicht den Zugriff auf lokale, mit DDC-erschlossene Titeldaten. Für einige bereits übersetzte DDC-Klassen kann mithilfe eines Browsers gearbeitet werden. Auch die gezielte verbale Suche nach DDC-Elementen ist möglich. Die Frage nach Aspekten, wie z. B. geografischen, soll durch getrennte Ablage der Notationselemente in den Titeldatensätzen ermöglicht werden. Schließlich lassen sich künftig auch integrierte Suchen über DDC und SWD oder andere Erschließungssysteme denken, um Literatur zu einem Thema zu finden. Das von Lars Svensson vorgestellte Retrieval-Interface bietet eine zentrale Lösung: nicht für jeden lokalen OPAC müssen eigene Suchstrukturen entwickelt werden, um auf DDC-Daten zugreifen zu können. Wie Datenbestände mit verschiedenen Erschließungen unter einer Oberfläche zusammengeführt werden und dabei die DDC als Meta-Ebene genutzt wird, das ist heute schon im Subject Gateway Renardus sichtbar." Der Renardus-Broker ermöglicht das Cross-Browsen und Cross-Searchen über verteilte Internetquellen in Europa. Für die Navigation über die DDC mussten zunächst Crosswalks zwischen den lokalen Klassifikationsklassen und der DDC erstellt werden. Das an der Universitätsbibliothek Regensburg entwickelte Tool CarmenX wurde dazu von der Niedersächsischen Staats- und Universitätsbibliothek Göttingen weiterentwickelt und ermöglicht den Zugriff auf die ver schiedenen Klassifikationssysteme. Über diese Entwicklungen berichtete Dr. Friedrich Geißelmann, Universitäsbibliothek Regensburg. Er leitete das CARMEN-Teilprojekt »Grosskonkordanzen zwischen Thesauri und Klassifikationen«, in dem das Werkzeug CarmenX entstand. In diesem CARMEN-Arbeitspaket erfolgten sowohl grundlegende methodische Untersuchungen zu Crosskonkordanzen als auch prototypische Umsetzungen in den Fachgebieten Mathematik, Physik und Sozialwissenschaften. Ziel war es, bei Recherchen in verteilten Datenbanken mit unterschiedlichen Klassifikationen und Thesauri von einem vertrauten System auszugehen und in weitere wechseln zu können, ohne genaue Kenntnis von den Systemen haben zu müssen. So wurden z. B. im Bereich Crosskonkordanzen zwischen Allgemein- und Fachklassifikationen die RVK und die Mathematical Subject Classification (MSC) und Physics and Astronomy Classification Scheme (PACS) ausgewählt.
