    Abstract
    Überblick über die Datennetze im Forschungszentrum Jülich. Im Mittelpunkt steht dabei der Zusammenhang zwischen den speziellen Anforderungen und Anwendungen eines zentralen Informationsdienstleisters (Zentralbibliothek) und der daraus resultierenden Gestaltung und Strukturierung der Datennetze. Es wird gezeigt, daß die zukünftige Netzlast der Informationsgesellschaft im Zeitalter von Multimedia nur mit modernster Lichtwellenleitertechnik zu bewältigen ist

    "Seit zwei Jahrzehnten nutzen vor allem Bibliotheksverbünde das Protokoll Z39.50, um ihren Benutzern im Internet die simultane Abfrage mehrerer Datenbanken zu ermöglichen. Jetzt gibt es einen Nachfolger dieses Protokolls, der eine einfachere Implementierung verspricht. Damit ist auch eine größere Verbreitung für die Suche in verteilten Datenbeständen anderer Institutionen, wie z.B. Archiven und Museen, wahrscheinlich. SRW/U (Search and Retrieve Web Service bzw. Search and Retrieve URL Service, www.loc.90v/z3950/agency/zing/srw) wurde von einer an der Library of Congress angesiedelten Initiative entwickelt und beruht auf etablierten Standards wie URI und XML. Die mit SRW und SRU möglichen Abfragen und Ergebnisse unterscheiden sich nur in der Art der Übertragung, verwenden aber beide dieselben Prozeduren. Davon gibt es nur drei: explain, scan und searchRetrieve. Die beiden Erstgenannten dienen dazu, allgemeine Informationen über den Datenanbieter bzw. die verfügbaren Indexe zubekommen. Das Herzstück ist die search-Retrieve-Anweisung. Damit werden Anfragen direkt an die Datenbank gesendet und die Parameter des Suchergebnisses definiert. Verwendet wird dafür die Retrievalsprache CQL (Common Query Language), die simple Freitextsuchen, aber auch mit Boolschen Operatoren verknüpfte Recherchen ermöglicht. Bei SRU werden die Suchbefehle mittels einfacher HTTP GET -Anfragen übermittelt, die Ergebnisse in XML zurückgeliefert. Zur Strukturierung der Daten dienen z.B. Dublin Core, MARC oder EAD. Welches Format von der jeweiligen Datenbank bereitgestellt wird, kann durch die explain-Anweisung ermittelt gebracht werden."

    Abstract
    Discusses the advantages and disadvantages of a common user interface to enable searching of all databases regardless of producer, supplier or location, such as local CD-ROM, or network. Explains client server architecture, the basic component of a common user interface and outlines current developments including the Z39.50 application layer protocol. A common user interface will result in greater synergy between information providers, technology providers, distributors and information professionals. It will also be able to search across the Internet and make that huge wealth of data much more available than it currently is. Predicts that a common user interface will be in operation by the turn of the century
