Abstract
Elektronische Publikationen sollen langfristig referenzierbar und benutzbar sein. Ein Ziel, das sich nur durch kooperative Aktivitäten im Bereich der Publikation, Erschließung und Langzeitarchivierung digitaler Ressourcen mit einer dauerhaften Infrastruktur realisieren lässt. Ein Aspekt in diesem Themenkomplex ist die dauerhafte Identifizierung elektronischer Publikationen verbunden mit einer Garantie zur langfristigen Adressierung. Die Deutsche Bibliothek sammelt seit Beginn des Projektes CARMEN-AP4 im September 2001 Erfahrungen in der Vergabe, Verwaltung und Auflösung von Persistent Identifiers (PI) in Form des internationalen Standards »Uniform Resource Names« (URN). Darauf aufbauend wurde im Rahmen des EPICUR-Projektes der Service erweitert und in eine produktive technische Umgebung überführt. Der vorliegende Artikel diskutiert den im EPICUR-Projekt verfolgten Ansatz zur Anwendung von URNs als primärer Persistent Identifier (PI), stellt die Ergebnisse dar und skizziert die Planungen zur Integration des EPICUR-Service in den Normalbetrieb Der Deutschen Bibliothek.
