    Web Usage Analysis for Assessing and Improving Metadata Quality
    (Managing Environmental Knowledge, 2006) Krieger, Rolf; Schöpflin-Reichmann, Elke; Sattler, Thomas; Schäfer, Kerstin
    Due to Directive 2003/4/EC on public access to environmental information public authorities have invested large amounts of money and time in metadata management projects. For instance, in Germany the Environmental Data Catalogue was designed as a Web-based meta information system for retrieving environmental information held by public authorities. The benefits of the system depend on the quality of the metadata provided. As well-known data quality is expressed in several dimensions, e.g. accessibility, completeness, relevancy, timeliness etc.. To guarantee a high metadata quality public authorities have to develop a long-term metadata management strategy concerning the Environmental Data Catalogue. At a tactical level this requires a continuous monitoring of the usage of the Environmental Data Catalogue. One attractive strategy for analyzing the usage of the system is the analysis of log files provided by the Environmental Data Catalogue. But to our knowledge only a few German authorities, e.g. the State Institute for Environment, Measurement and Nature Conservation Baden Württemberg, have started to analyse the UDK-log files continuously in a systematic way. The reasons are: (a) The UDK-software only provides rudimentary support for managing the logging process. (b) It is difficult to analyse the log files because there are no metrics and no tool for analyzing the application-specific log files of the Environmental Data Catalogue. Due to these facts in our contribution we present procedures, metrics and a tool for analysing the specific UDK-log files. The UDK Log-File-Analyser receives the daily log files as input, aggregates and analyses the data and provides a summary report, a weekly report, an error report and a search term evaluation report as result. The reports list several metrics (e.g. number of sessions and object views, list of most popular UDK-objects, list of most popular search terms etc.). The statistics are presented in tabular and graphical form. Using our tool we analysed the daily log files of the Environmental Data Catalogue of the German State of Baden-Württemberg from October 1st, 2003 to October 31st, 2004. Thereby we identified several data quality problems with respect to content and accessibility. To solve these problems, we derived several activities from our empirical study. For instance based on the search term evaluation report produced by our tool the most popular keywords can be identified. Assigning these keywords to relevant UDK-objects improves the accessibility of the data. In addition our tool provides a list of search terms for which the Environmental Data Catalogue has not delivered relevant objects. This list can help identify missing objects. Adding these objects improves the completeness of data. In summary, with our tool and metrics public authorities have instruments for guiding their meta data management and for improving metadata quality concerning the Environmental Data Catalogue. Moreover, our results show that web usage analysis is a promising way to gain insights into the environmental information demand of the public.

    Knowledge Management Tools within the National Biological Information Infrastructure (NBII)
    (Managing Environmental Knowledge, 2006) Frame, Michael T.; Cotter, Gladys
    Several Knowledge management tools have greatly enhanced the U.S. Geological Survey National Biological Information Infrastructure (http://www.nbii.gov) ability to deliver high quality scientific information to researchers, decision makers, and ultimately the general public. These include various cataloging, thesauri, collaboration, spatially oriented, and integrated portal tools. For instance, the use of thesauri in the retrieval of information has been in practice for the past several years. However, the use of these knowledge management systems as a framework in supporting Internet based retrieval of biological information is still relatively new. The NBII has benefited significantly from this approach in the areas of thesauri and portals through providing customized, tailored, and user driven access to information. Also, through the use of web-services, various weighting algorithms, pre defining search results, and integration with other international thesauri, biological users are able to discover information that was once not available via traditional query methods.

    WaterFrame® A Software Framework for the Development of WFD-oriented Water Information Systems
    (Managing Environmental Knowledge, 2006) Schmid, Holger; Usländer, Thomas
    In Europe, the development of Environmental Information Systems for the water domain is mainly influenced by the requirements of the European Water Framework Directive (WFD). The WFD is a fundamental rethink of the EU water policy aiming at sharing water data across administrative borders. Its implementation therefore is also a challenge for the supporting WFD-specific information management. As the WFD by itself includes concrete IT recommendations only on a very high-level of data exchange, regional and/or national environmental agencies still have to build or adapt their information systems according to their specific requirements. On this background, the present article introduces the software framework WaterFrame® – designed by Fraunhofer IITB – that supports the development of WFD-oriented water information systems. The selected features described are illustrated by practical examples taken from projects already powered by WaterFrame®. The paper presents the two WaterFrame® installations WAABIS Grundwasser, installed in the German federal state of Baden-Wuerttemberg, and FIS Gewässer (German Free State of Thuringia). The results of using WaterFrame® as a development platform are twofold: On the one hand, development time and costs can be significantly reduced, on the other hand the generated systems are widely integrative, i. e. further development of one of them can be adopted within others with little effort and low costs.

    Development of Company EHS (Environmental, Health and Safety) Information Management System in Multinational Environment
    (Managing Environmental Knowledge, 2006) Kothencz, Janos; Gaspar, Janos; Perenyi, Gabor
    In case of multinational companies there is an emerging demand to introduce uniform company EHS Information System in support of EHS processes, that on the one hand fulfils the local legal requirements and specific business needs characteristic to the given country and on the other hand provides uniform EHS and business information for the management of the company. As a possible solution a model has been elaborated and implemented in the course of the development of MOL Group (MOL Group comprises some major central European oil, gas and chemical companies) EHS Information System. The model is able to fulfil different national requirements and it can achieve the necessary level of integration. The Oracle10g Developer Suite development environment has to be used for developing the EHS Info system, and it contains the Oracle10g JDeveloper J2EE development environment, as well as the Oracle10g Reports Developer environment. The system does not stipulate any special hardware requirements for the client computers. The database server is IBM Z800 type server, the applications server is also an Intel-based IBM server. Every one of the network connections function over a TCP/IP-based network protocol. The clients communicate with applications servers over the http protocol, while there are Oracle NET protocol based communications among the applications and database servers. The system stores the data in the Oracle9i Database Release2 Enterprise Edition database engine software. The applications server is implemented on the Oracle10gAS Enterprise Edition software package. The HTTP server functionalities are based on Apache’s HTTP server version 1.3.22.The clients run Microsoft operating systems, there are only constraints concerning the Explorer, and Acrobat Reader. As regards functionality the information system comprises two distinct types of modules: the national modules and the integration module. The national modules serve the purpose of data recording and maintenance. This surface supports the data providing and report generation for local authorities in the format defined in the national legislation (e.g. waste management reports, air emission reports etc.). Until now the national modules for Hungary and Slovakia have been introduced. The integration module ensures the possibility to generate management information and statistics as defined by the internal rules of the company. The surface of the integration module generates the reports from data stored in the national modules, but these reports are generated according to the general rules applying to the entire company. As the result of the applied model the information system is able to support the EHS management processes and decisions of the company, register and store EHS data in a structured database (currently contains all EHS related data of more then 2000 sites), generate EHS reports according to national legislation.
