    Editing ISO 19115 Compliant Metadata in EUROSION
    (The Information Society and Enlargement of the European Union, 2003) Kazakos, Wassilios; Akhounov, Alexei; Paoli, Heiko; Behrens, Sven; Niesing, Hugo; Lombardo, Stephane
    EUROSION is a project commissioned by the General Directorate Environment of the European Commission, which will result in policy recommendations on how to manage coastal erosion in Europe in the most sustainable way. In this paper we focus on the EUROSION Information System and new technological aspect in metadata based information systems. We leverage XML and adjacent technologies as well as International Standard ISO 19115 to point different issues, such as ease of development and maintenance, ergonomics and interoperability.

    Harmonisierter Zugang zu Umweltinformationen für Öffentlichkeit, Politik und Planung: Der Umweltdatenkatalog UDK im Einsatz
    (Umweltinformatik ’00 Umweltinformation für Planung, Politik und Öffentlichkeit, 2000) Swoboda, Walter; Kruse, Fred; Legat, Rudolf; Nikolai, Ralf; Behrens, Sven
    The Umweltdatenkatalog (UDK = Environmental data catalogue) is a metainformation system for locating environmental information available in public authorities. The UDK is introduced in Austria and Germany. This article addresses problems and solutions concerning harmonisation of metainformation. Special interest is given to aspects of collecting and querying metainformation as well as the use of UDK as a meta component of other information systems. The newly developed Virtual UDK allows to start a parallel query in the Internet applications of all involved UDK co-operation partners.

    Informationsvernetzung am Beispiel des WWW-UDK
    (Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Behrens, Sven; Nikolai, Ralf; Kruse, Fred; Karschnik, Oliver
    Das Web ist die grundlegende Technologie für Informationszugriffe jederzeit und über- all. Die aktuelle Herausforderung bei der Weiterentwicklung von Web- Informationssystemen besteht darin, Informationen aus heterogenen und verteilten Quel- len nahtlos zu integrieren. In diesem Beitrag zeigen wir am Beispiel des WWW-UDK wie sich die technologischen Grundlagen der Vernetzungsmöglichkeiten in den letzen 5 Jahren verändert haben und welcher Nutzen sich daraus ergeben kann.

    The UDK and ISO 19115 Standard
    (The Information Society and Enlargement of the European Union, 2003) Karschnick, Oliver; Kruse, Fred; Töpker, Stefanie; Riegel, Thomas; Eichler, Marco; Behrens, Sven
    The German Environmental Data Catalogue UDK (German: Umweltdatenkatalog) is the standard tool for public access to environmental metadata in Germany and Austria. Considering the necessity of presenting more data from different sources in a homogeneous way, the UDK needs a normative data model for exchanging easily data with other databases like GeoMIS.Bund. In order to achieve this aim the UDK data model is extended to be compatible with the ISO 19115 standard (International Organization for Standardization) for geographic Information, finally aiming to fulfill the Directive of the European Parliament and of the Council on public access to environmental information. In this paper an actual review about the UDK is given and the development of the ISO 19115 compatibility is presented. Zusammenfassung Der Deutsche Umweltdatenkatalog UDK ist die Standardanwendung für den öffentlichen Zugang zu Umweltmetadaten in Deutschland und Österreich. Aufgrund der Notwendigkeit, immer mehr Umweltdaten aus unterschiedlichen Quellen einheitlich darzustellen, benötigt der UDK ein normiertes Datenmodel, so dass der Datenaustausch mit anderen Systemen, wie z.B. GeoMIS.BUND ermöglicht wird. Um dieses Ziel zu erreichen, wird das UDK Datenmodell gemäß des ISO 19115 Standards (International Organization for Standardization) erweitert, sodass die Richtlinie 2003/4/EG über den Zugang der Öffentlichkeit zu Umweltinformationen erfüllt wird. In diesem Artikel wird ein aktueller Überblick über den UDK gegeben und die Anpassung an die ISO 19115 vorgestellt.

    The UDK, Present Status and Future Development - An Overview
    (Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Kruse, Fred; Karschnick, Oliver; Spöringer, Anja; Eichler, Marco; Behrens, Sven
    The Environmental Data Catalog (UDK) is a system for public access to environmental data for which various tools have been developed to collect Metadata and present them in the internet. Through various interfaces it is possible to do research in other metadata systems and merge the result in a common way. In the other direction the interfaces of the UDK can be used for research and data-retrieval by other information systems like the German Environmental Information Network (GEIN).

    WWW-UDK 4.0: Die neue Generation eines WebPortals zu deutschen und österreichischen Umweltdaten
    (Umweltinformatik ’99 - Umweltinformatik zwischen Theorie und Industrieanwendung, 1999) Nikolai, Ralf; Kazakos, Wassili; Kramer, Ralf; Behrens, Sven; Swoboda, Walter; Kruse, Fred
    Since its introduction in 1995 the environmental data catalogue UDK (Umweltdatenkatalog) has become a de-facto standard for environmental meta-information in German and Austrian governmental organisations. During the last year, the fourth generation of WWW-UDK, a tool for publishing UDK data on the Web, was developed based on a careful user requirement analysis. A complete redesign of the software makes possible that on the one hand advanced Internet technologies could be employed and on the other hand the various requirements of the different user groups could be fulfilled. To do so, three main components have been developed: (1) HTML-UDK which provides full retrieval functionality and requires minimal client equipment only. (2) J-UDK, an integrated Java applet of graphical, interactive tools for advanced users. (3) Virtual UDK which provides for the first time searches over distributed UDK data of different catalogues. Furthermore the interaction of WWW-UDK and WinUDK is presented.
