    Abstract
    Das von der Europäischen Union seit Januar 2000 geförderte Projekt Renardus hat das Ziel, einen Service zur Nutzung der in Europa vorhandenen "Quality-controlled Subject Gateways" aufzubauen, d.h. über einen Zugang bzw. eine Schnittstelle crosssearchen und crossbrowsen anzubieten. Für das crossbrowsen wird dabei zum Navigieren die Dewey Decimal Classification (DDC) verwendet. Der Beitrag beschreibt die einzelnen Entwicklungsschritte und stellt detailliert die nötigen Mappingprozesse vor. Dabei handelt es sich einmal um Mappingprozesse von den lokalen Metadatenformaten der einzelnen Subject Gateways zu dem gemeinsamen Kernset an Metadaten in Renardus für die Suche, wobei dieses Kernset auf dem Dublin Core Metadata Set basiert. Zum anderen geht es um die Erstellung von Konkordanzen zwischen den lokalen Klassen der Klassifikationssysteme der Partner und den DDC-Klassen für das Browsen. Der Beitrag beschreibt auch neue zugrunde liegende Definitionen bzw.theoretische Konzepte, die in der Metadatengemeinschaft zurzeit diskutiert werden (z.B. Application Profile, Namespace, Registry). Zum Schluss werden die Funktionalitäten des Renardus-Services (suchen, browsen) näher vorgestellt.

    Abstract
    Eine wichtige Aufgabe der Informationsverarbeitung als fachbezogene Informatik besteht darin, die neue Entwicklung der Informationstechnologie zu verfolgen, sich damit auseinanderzusetzen, inwieweit diese Entwicklung die Forschung sowie die Anwendung in der Geisteswissenschaft unterstützen kann, und die daraus entstandenen Konzepte zu realisieren. Das im Jahre 1999 veröffentlichte Nachrichtenaustauschprotokoll SOAP (Abkürzung für Simple Object Access Protocol) entstand vor dem Hintergrund der schnellen Entwicklung der Vernetzung besonders des Internets. In den letzten Jahren hat SOAP große Aufmerksamkeit auf sich gezogen, weil man mit SOAP einige Beschränkungen der vorhandenen Techniken überwinden kann und damit die Leistungsfähigkeit der Software sowie Anwendung wesentlich verbessern kann. Ziel der Magisterarbeit liegt darin, einerseits theoretisch über die Möglichkeit des Einsetzens von SOAP in der Bibliotheksanwendung zu untersuchen, andererseits das Ergebnis der theoretischen Untersuchung in die Praxis umzusetzen, d.h. das Konzept eines Bibliotheksanwendungssystems mit dem Einsatz von SOAP zusammenzustellen und es zu realisieren. SOAP ist ein Nachrichtenprotokoll, das die Kommunikationen zwischen entfernten Systemen unterstützt. In der Arbeit wird durch eine theoretische Untersuchung gezeigt, dass SOAP sich besonders gut für die in der stark heterogenen Umgebung wie Internet verteilte Anwendung eignet. Eine der häufig von dem Bibliotheksystem über das Internet angebotenen verteilten Anwendungen ist der verteilte OPAC. Ein verteilter OPAC bietet eine verteilte Suche in mehreren Bibliothekssystemen an. Die meisten bisherigen Bibliothekssysteme realisieren die verteilte Suche vorwiegend mit der Unterstützung des Protokolls Z39.50. Durch die theoretische Untersuchung ist es zu sehen, dass mit dem Einsatz von SOAP einerseits der Arbeitsaufwand in der Realisierung bzw. die Verwaltung des Systems verglichen mit dem Z39.50 reduziert, andererseits die Funktionalität des Systems stark erweitert wird, dass eine Zusammenarbeit des Bibliothekssystems mit den Systemen anderer Bereiche leicht realisiert werden kann. Als praktisches Projekt der Magisterarbeit wird ein System der verteilten OPACs mit SOAP als Nachrichtenaustauschprotokoll entwickelt.

    Rez. in: KO 31(2004) no.2, S.117-118 (D. Campbell): "This excellent volume offers 22 papers delivered at an IFLA Satellite meeting in Dublin Ohio in 2001. The conference gathered together information and computer scientists to discuss an important and difficult question: in what specific ways can the accumulated skills, theories and traditions of librarianship be mobilized to face the challenges of providing subject access to information in present and future networked information environments? The papers which grapple with this question are organized in a surprisingly deft and coherent way. Many conferences and proceedings have unhappy sessions that contain a hodge-podge of papers that didn't quite fit any other categories. As befits a good classificationist, editor I.C. McIlwaine has kept this problem to a minimum. The papers are organized into eight sessions, which split into two broad categories. The first five sessions deal with subject domains, and the last three deal with subject access tools. The five sessions and thirteen papers that discuss access in different domains appear in order of in creasing intension. The first papers deal with access in multilingual environments, followed by papers an access across multiple vocabularies and across sectors, ending up with studies of domain-specific retrieval (primarily education). Some of the papers offer predictably strong work by scholars engaged in ongoing, long-term research. Gerard Riesthuis offers a clear analysis of the complexities of negotiating non-identical thesauri, particularly in cases where hierarchical structure varies across different languages. Hope Olson and Dennis Ward use Olson's familiar and welcome method of using provocative and unconventional theory to generate meliorative approaches to blas in general subject access schemes. Many papers, an the other hand, deal with specific ongoing projects: Renardus, The High Level Thesaurus Project, The Colorado Digitization Project and The Iter Bibliography for medieval and Renaissance material. Most of these papers display a similar structure: an explanation of the theory and purpose of the project, an account of problems encountered in the implementation, and a discussion of the results, both promising and disappointing, thus far. Of these papers, the account of the Multilanguage Access to Subjects Project in Europe (MACS) deserves special mention. In describing how the project is founded an the principle of the equality of languages, with each subject heading language maintained in its own database, and with no single language used as a pivot for the others, Elisabeth Freyre and Max Naudi offer a particularly vivid example of the way the ethics of librarianship translate into pragmatic contexts and concrete procedures. The three sessions and nine papers devoted to subject access tools split into two kinds: papers that discuss the use of theory and research to generate new tools for a networked environment, and those that discuss the transformation of traditional subject access tools in this environment. In the new tool development area, Mary Burke provides a promising example of the bidirectional approach that is so often necessary: in her case study of user-driven classification of photographs, she user personal construct theory to clarify the practice of classification, while at the same time using practice to test the theory. Carol Bean and Rebecca Green offer an intriguing combination of librarianship and computer science, importing frame representation technique from artificial intelligence to standardize syntagmatic relationships to enhance recall and precision.
