    Abstract
    In den ersten Jahren der Internetdienste wurde auf Klassifikationen weitgehend verzichtet. Viele Anbieter argumentierten, daß diese wie auch andere Metadaten von der Entwicklung aufgrund der Volltextindices überholt sind. Inzwischen hat sich das Blatt gewendet: Die meisten der großen Suchdienste bieten eine mehr oder minder ausgefeilte Klassifikation an. eine Reihe von Internetdiensten verwendet etablierte Bibliotheksklassifikationssysteme; deren Einsatzbereiche, die Vor- und Nachteile sowie Anwendungsbeispiele sind Thema dieses Aufsatzes

    Abstract
    Die verschiedenen Methoden und Instrumente des Navigierens bzw. des Information Retrieval im Internet werden anhand von Beispielen im Überblick vorgestellt. Der Schwerpunkt liegt dabei auf den drei verbreitesten Werkzeugen Gopher, WWW und WAIS. Schwächen un Defizite werden aus der Sicht des Endnutzers analysiert und einige notwendige bzw. wünschenswerte Verbesserungen benannt. Einige Initiativen und Vorschläge zur Weiterentwicklung der Werkzeuge im Netz, teilweise angeregt von einem Blick auf Navigierungs- und Retrievalinstrumente aus Forschung und Entwicklung werden beschrieben

    Abstract
    Immer häufiger werden das System 'Internet', die dort genutzten Programmfunktionen und Werkzeuge sowie die damit zugänglichen Informationsangebote in Fachdiskussionen und -veröffentlichungen vorgestellt. Als einführende Hilfsmittel und Ratgeber zur Information über dieses Netzwerk sowie zur eigentlichen Nutzung von Internet sind (neben in elektronischer Form vorliegenden Publikationen) mittlerweile mehrere einführende Printveröffentlichungen in englischer Sprache auf dem Markt. Drei dieser Publikationen werden im vorliegenden Artikel ausführlicher vorgestellt und bewertet. Zum besseren Verständnis des sachlichen Zusammenhangs ist der Rezension ein knapp gefaßter Überblick über die unter dem Begriff 'Internet' zusammengefaßten Funktionen und Informationsangebote vorangestellt.

    Abstract
    'Quality-controlled subject gateways' are Internet services which apply a rich set of quality measures to support systematic resource discovery. Considerable manual effort is used to secure a selection of resources which meet quality criteria and to display a rich description of these resources with standards-based metadata. Regular checking and updating ensure good collection management. A main goal is to provide a high quality of subject access through indexing resources using controlled vocabularies and by offering a deep classification structure for advanced searching and browsing. This article provides an initial empirical overview of existing services of this kind, their approaches and technologies, based on proposed working definitions and typologies of subject gateways

    Abstract
    Defines metadata, which for librarians means catalogue records for printed publications, and the need for them in document retrieval. The existence of many different sources of metadata had led to a need for simpler metadata schemes and a stadardised exchange format. The 1st Metadata Workshop, held in Dublin, Ohio, reached consensus on a simple resource description record, known as the Dublin core set, with 13 elements, which can serve to unify various models. Lists institutions intending to use it. The 2nd workshop resulted in a proposal for a container record architecture comprising more and different types of metadata than a Dublin core record. The Nordic Metadata project, outlined here, aims to improve the knowledge transfer to the Nordic countries and allow them to paricipate actively in international developments

    Abstract
    Metadata is a keystone component for a broad spectrum of applications that are emerging on the Web to help stitch together content and services and make them more visible to users. The Dublin Core Metadata Initiative (DCMI) has led the development of structured metadata to support resource discovery. This international community has, over a period of 6 years and 8 workshops, brought forth: * A core standard that enhances cross-disciplinary discovery and has been translated into 25 languages to date; * A conceptual framework that supports the modular development of auxiliary metadata components; * An open consensus building process that has brought to fruition Australian, European and North American standards with promise as a global standard for resource discovery; * An open community of hundreds of practitioners and theorists who have found a common ground of principles, procedures, core semantics, and a framework to support interoperable metadata. The 8th Dublin Core Metadata Workshop capped an active year of progress that included standardization of the 15-element core foundation and approval of an initial array of Dublin Core Qualifiers. While there is important work to be done to promote stability and increased adoption of the Dublin Core, the time has come to look beyond the core elements towards a broader metadata agenda. This report describes the new mission statement of the Dublin Core Metadata Initiative (DCMI) that supports the agenda, recapitulates the important milestones of the year 2000, outlines activities of the 8th DCMI workshop in Ottawa, and summarizes the 2001 workplan.

    Abstract
    This paper presents the approach and first results of the classification mapping process in the EU project Renardus. The outcome in Renardus is a cross-browsing feature based an the Dewey Decimal Classification (DDC) and improved subject searching across distributed and heterogeneous European subject gateways. The paper presents the project's initial experiences and decisions, e.g. an investigation of the use of classification systems by Renardus partners' gateways, general mapping approaches and issues, the definition of mapping relationships and some information an technical solutions and the mapping tool. There is also a demonstration of the use of the mapping information in Renardus and the presentation of several features that have been implemented to aid end-user navigation in a large and deep browsing structure like the DDC. Classification mapping for crossbrowsing is a labour intensive and complex effort which at the moment raises many open questions and leaves many more future potential work tasks than completed useful solutions.

    "1. The EU projeet Renardus Renardus is a project funded by the European Commission as part of the Information Society Technologies (IST) programme, part of the European Union's 5th Framework Programme. Partners in Renardus include national libraries, research centres and subject gateway services from Denmark, Finland, Germany, The Netherlands, Sweden and the UK, co-ordinated by the National Library of the Netherlands. The project aims to develop a Web-based service to enable searching and browsing across a range of distributed European-based information services designed for the academic and research communities - and in particular those services known as subject gateways. These gateways are services that provide access to Internet resources. They tend to be selective with regard to the resources they give access to, and are usually based an the manual creation of descriptive metadata. Services typically provide users with both search and browse facilities, and offen offer hierarchical browse structures based an subject classification schemes (Koch & Day, 1997). Predecessor projects like the EU project DESIRE have already developed solutions for the description of individual resources and for automatic classification at the level of an individual subject gateway using established classification systems. Renardus intends to develop a service that can cross-search and cross-browse a number of distributed subject gateways through the use of a common metadata profile and by the mapping all locally-used classification schemes to a common scheme. A thorough review of existing data models (Becker, et al., 2000) was used as the basis for the agreement of a minimum set of Dublin Core-based metadata elements that could be utilised as a common data model. A comprehensive mapping effort from the individual gateways' metadata element sets and content encoding schemes to the common profile has taken place. This provides the infrastructure for interoperability between all participating databases and thus is the necessary prerequisite for cross-searching."
