Abstract

Aktuell befinden sich im Datenbestand des gemeinsamen Katalogs des Bibliotheksverbundes Bayern und des Kooperativen Bibliotheksverbundes Berlin-Brandenburg (B3Kat) etwa 25,6 Millionen Titeldatensätze. Die Bayerische Verbundzentrale veröffentlicht diese Daten seit 2011 im Zuge der bayerischen Open-Data-Initiative auf ihrer Webpräsenz. Zu den Nachnutzern dieser Daten gehören die Deutsche Digitale Bibliothek und das Projekt Culturegraph der DNB. Die Daten werden im weitverbreiteten Katalogdatenformat MARCXML publiziert. Zur Erzeugung der XML-Dateien verwendete die Verbundzentrale bis 2014 die Windows-Software MarcEdit. Anfang 2015 entwickelte der Verfasser im Rahmen der bayerischen Referendarsausbildung einen einfachen MARC-21-MARCXML-Konverter in Perl, der die Konvertierung wesentlich erleichert und den Einsatz von MarcEdit in der Verbundzentrale überflüssig macht. In der vorliegenden Arbeit, die zusammen mit dem Konverter verfasst wurde, wird zunächst die Notwendigkeit einer Perl-Implementierung motiviert. Im Anschluss werden die bibliographischen Datenformate MARC 21 und MARCXML beleuchtet und für die Konvertierung wesentliche Eigenschaften erläutert. Zum Schluss wird der Aufbau des Konverters im Detail beschrieben. Die Perl-Implementierung selbst ist Teil der Arbeit. Verwendung, Verbreitung und Veränderung der Software sind unter den Bedingungen der GNU Affero General Public License gestattet, entweder gemäß Version 3 der Lizenz oder (nach Ihrer Option) jeder späteren Version.[Sie finden die Datei mit der Perl-Implementierung in der rechten Spalte in der Kategorie Artikelwerkzeuge unter dem Punkt Zusatzdateien.]
