    Abstract
    Das »Semantic Web« bildet einen der wichtigsten, aktuellen Trends in der Weiterentwicklung des World Wide Web. Ehrgeizige Vision dieser nächsten Generation des WWW ist es, durch semantische Anreicherung von Information eine neue Qualität in der Bereitstellung von Inhalten und Diensten zu erreichen und vollständig neue Anwendungsmöglichkeiten für das Web zu eröffnen. Wichtige Ziele der Entwicklung des Semantic Web sind dabei die verbesserte Unterstützung von Kooperation zwischen Menschen und Computern und die intelligente Assistenz bei der Durchführung von Aufgaben in kooperativen verteilten Informationsumgebungen. Schlüssel zur Erreichung dieser Ziele sind die Anreicherung von Daten im Web mit Metadaten, welche diese Daten in einen semantischen Kontext einbetten. Diese Kontextinformation wird durch Software-Anwendungen interpretiert und zur Informationsfilterung, Verfeinerung von Anfragen und zur Bereitstellung intelligenter Assistenten verwendet. Eine große Herausforderung stellt dabei die geeignete Modellierung und Beschreibung des Kontexts dar. Diese muss eine automatische, globale Interpretation ermöglichen, ohne dass auf ein allgemeingültiges semantisches Beschreibungsschema zurückgegriffen werden kann. Die Vereinbarung eines solchen allgemeingültigen Schemas ist in einem derart umfangreichen, heterogenen und autonomen Rahmen, wie ihn das WWW darstellt, nicht möglich.

    Abstract
    * Agencies maintaining directories of data elements in a domain area in accordance with ISO/IEC 11179 (This standard specifies good practice for data element definition as well as the registration process. Example implementations are the National Health Information Knowledgebase hosted by the Australian Institute of Health and Welfare and the Environmental Data Registry hosted by the US Environmental Protection Agency.); * The xml.org directory of the Extended Markup Language (XML) document specifications facilitating re-use of Document Type Definition (DTD), hosted by the Organization for the Advancement of Structured Information Standards (OASIS); * The MetaForm database of Dublin Core usage and mappings maintained at the State and University Library in Goettingen; * The Semantic Web Agreement Group Dictionary, a database of terms for the Semantic Web that can be referred to by humans and software agents; * LEXML, a multi-lingual and multi-jurisdictional RDF Dictionary for the legal world; * The SCHEMAS registry maintained by the European Commission funded SCHEMAS project, which indexes several metadata element sets as well as a large number of activity reports describing metadata related activities and initiatives. Metadata registries essentially provide an index of terms. Given the distributed nature of the Web, there are a number of ways this can be accomplished. For example, the registry could link to terms and definitions in schemas published by implementers and stored locally by the schema maintainer. Alternatively, the registry might harvest various metadata schemas from their maintainers. Registries provide 'added value' to users by indexing schemas relevant to a particular 'domain' or 'community of use' and by simplifying the navigation of terms by enabling multiple schemas to be accessed from one view. An important benefit of this approach is an increase in the reuse of existing terms, rather than users having to reinvent them. Merging schemas to one view leads to harmonization between applications and helps avoid duplication of effort. Additionally, the establishment of registries to index terms actively being used in local implementations facilitates the metadata standards activity by providing implementation experience transferable to the standards-making process.
