- Abstract
- We propose an extension of a mediator architecture. This extension is oriented to ontology-driven data integration. In our architecture ontologies are not managed by an extemal component or service, but are integrated in the mediation layer. This approach implies rethinking the mediator design, but at the same time provides advantages from a database perspective. Some of these advantages include the application of optimization and evaluation techniques that use and combine information from all abstraction levels (physical schema, logical schema and semantic information defined by ontology). 1. Introduction Although the Web is probably the richest information repository in human history, users cannot specify what they want from it. Two major problems that arise in current search engines (Heflin, 2001) are: a) polysemy, when the same word is used with different meanings; b) synonymy, when two different words have the same meaning. Polysemy causes irrelevant information retrieval. On the other hand, synonymy produces lost of useful documents. The lack of a capability to understand the context of the words and the relationships among required terms, explains many of the lost and false results produced by search engines. The Semantic Web will bring structure to the meaningful content of Web pages, giving semantic relationships among terms and possibly avoiding the previous problems. Various proposals have appeared for meta-data representation and communication standards, and other services and tools that may eventually merge into the global Semantic Web (Berners-lee, 2001). Hopefully, in the next few years we will see the universal adoption of open standards for representation and sharing of meta-information. In this environment, software agents roaming from page to page can readily carry out sophisticated tasks for users (Berners-Lee, 2001). In this context, ontologies can be seen as metadata that represent semantic of data; providing a knowledge domain standard vocabulary, like DTDs and XML Schema do. If its pages were so structured, the Web could be seen as a heterogeneous collection of autonomous databases. This suggests that techniques developed in the Database area could be useful. Database research mainly deals with efficient storage and retrieval and with powerful query languages.

- Abstract
- Mit elektronischem Publizieren werden folgende Eigenschaften verbunden: »schnell, kostengünstig, weltweit«. Aber ist das aus Nutzersicht bzw. aus der Perspektive der Autoren ausreichend, um eine Online-Veröffentlichung dauerhaft zu nutzen und zuverlässig zu zitieren? Ein Mechanismus, mit dem netzbasierte Publikationen eindeutig gekennzeichnet werden und jederzeit auffindbar sind, wird durch flüchtige Uniform Resource Locator (URLs) nicht bereitgestellt. Eine Lösung bieten Persistent Identifiers (Pls), wie z. B. Uniform Resource Names (URN)". Damit die Anwendung eines persistenten Adressierungsschemas wie den URNs langfristig gewährleistet werden kann, muss eine Infrastruktur mit einer institutionellen Unterstützung geschaffen werden. Ein wesentlicher Aspekt in diesem Kontext ist die Langzeitarchivierung der digitalen Objekte. Die Darstellung und Erläuterung der Schnittstellen zwischen Langzeitarchivierung und Pls sowie der damit verbundenen Aktivitäten und Ergebnisse des EPICUR-Projektes war Gegenstand des Vortrages von Kathrin Schroeder auf dem diesjährigen z. Bibliothekskongress in Leipzig im Rahmen des Workshops »Technische Aspekte der Langzeitarchivierung«". Es besteht ein enger Zusammenhang zwischen den Bereichen Pls (standortunabhängige, eindeutige Bezeichner für digitale Objekte) und Langzeitarchivierung (Maßnahmen, die dazu dienen, digitale Objekte für die Nachwelt dauerhaft zu erhalten): Pls werden als stabiler Zugriffsmechanismus für digitale Objekte verwendet, die in einem Depotsystem archiviert werden. Ein Depotsystem ist ein »( ...) Archiv für digitale Objekte, in dem Menschen und Systeme als 'Organisation' mit der Aufgabenstellung zusammenwirken, Informationen zu erhalten und einer definierten Nutzerschaft verfügbar zu machen.« Dazu gehören im erweiterten Sinne auch eine Infrastruktur vor der Eingangsschnittstelle des Depotsystems, die zum Transfer digitaler Objekte von den Produzenten in das Archiv dient, und die Infrastruktur der Endnutzer-Umgebungen hinter der Auslieferungsschnittstelle des Depotsystems, in denen die digitalen Objekte benutzt werden sollen. In diesem Umfeld werden Pls in folgenden Bereichen angewendet: - Metadaten, - Datenaustauschformate, - Automatisierte Lieferungen von Objekten in ein Archivsystem, - Depotsystem und - Nutzung von Pls als stabiler Zugriffsmechanismus auf ein Objekt als wichtigster Aspekt für den Endnutzer (Wissenschaftler und Autoren). Im Folgenden werden zu den einzelnen Bereichen die Ergebnisse des EPICUR-Projektes und die Aktivitäten Der Deutschen Bibliothek diskutiert.
