    Abstract
    This study explores the navigation behaviour of all users of a large web service, Renardus, using web log analysis. Renardus provides integrated searching and browsing access to quality-controlled web resources from major individual subject gateway services. The main navigation feature is subject browsing through the Dewey Decimal Classification (DDC) based on mapping of classes of resources from the distributed gateways to the DDC structure. Among the more surprising results are the hugely dominant share of browsing activities, the good use of browsing support features like the graphical fish-eye overviews, rather long and varied navigation sequences, as well as extensive hierarchical directory-style browsing through the large DDC system.

    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."

    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
    Under the auspices of the Desire II project, researchers at NetLab and OCLC are providing searching and browsing of a test collection of engineering documents on the Web. The goal of the project is to explore simple methods of automatic classification to provide subject browsing of a robot-generated engineering index. At NetLab the documents are automatically classified and organized using an engineering-specific scheme, the Engineering Index (Ei) Thesaurus and Classification; at OCLC the Dewey Decimal Classification (DDC), a general knowledge organization scheme, is being used

    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.
