    FINDEX - Sharing Substance Information
    (Sh@ring – EnviroInfo 2004, 2004) Menger, Matthias; Jahnke, Petra
    FINDEX offers a system that allows to share (substance) information without compromising legacy information system used for specific purposes. It is a fully fledged substance information system designed to integrate data of different data models under one umbrella. FINDEX derive meta data from the underlying information systems and merge it to a comprehensive information component to ease the search & retrieval process while hiding confidential data. The single sign-in solution offers a homogenous working environment for users which are not familiar with the different underlying systems. The virtual data mapping to a common format without compromising their original context ensures the comparability of data though from different systems. FINDEX open up and enable a better use of already available data and therefore foster sharing of information and knowledge.

    GSBL — Concept + Software Suite of an Information System for Chemical Substances
    (The Information Society and Enlargement of the European Union, 2003) Jahnke, Petra; Menger, Matthias
    The 'Gemeinsamer Stoffdatenpool Bund / Länder – GSBL’ (www.gsbl.de) is a joint data pool and information system for chemical (hazardous) substances. The GSBL is a ‘framework’ to collate and provide high quality data, based on an agreed concept and to encourage the data exchange between administrations. A general approach defines how to build a joint data pool and furthermore, a complete software suite to facilitate the use and maintenance of such a data pool. The GSBL software suite is a fully operational system of modules which enables the user to produce and handle complex chemical data and information. The technical data model comprises all available chemical information, including chemical structures, as well as classifications of legal regulations and therefore offers authorised information on present-day legislation. The flexibility and scalability of the software modules allows it to cover different requirements of various user levels. The GSBL offers an ‘eGovernment’ G2G2 application which supports communication and efficient co-operation between administrations. Furthermore, it provides important information for the general public. This would be very useful in the context of future Euro-pean chemical and environmental information systems.

    Migrating to Modern Web Technologies - Experiences in Re-Designing a Substance Retrieval Systems
    (Environmental Informatics and Systems Research, 2007) Menger, Matthias; Jahnke, Petra; Eiblmaier, Josef
    The successfully running search & retrieval applications for the substance database GSBL have been coming to age and need to reflect more the new needs of users dealing with modern networks and infrastructures. In its first version, the substance database GSBL used to be a classical desktop application. Performant access (the combination of throughput, response time, availability, and functionalities) was restricted to a narrow group of users having a desktop (fat) client installed. This allows a very performing client application with a wide range of functionalities which make this search & retrieval system unique in its class of substance information systems. Search and retrieval of substructures in more than 200.000 chemicals within a fraction of a second has been just one essential feature. With the growing of wider and better networks, more users and the approach to use software as a service, the obstacles of a pure client application become obvious. Innovative Web technologies and the availability of ever better performing networks allow to provide information to broad public more easily, faster and more convenient. Functionalities for search & retrieval do not need a fat client including installation and administration burdens. Just using your browser to get the same qualified information from everywhere you have access to the network was the aim of the re-design. Therefore, the cutting-edge technologies like Apache STRUTS, Ajax and JSTL were applied to create an easy to handle and efficient web application named 'GSBL Web application 3.0'. The following paper will describe the choice of technologies which fulfil best the needs of current and potential GSBL-users. This re-design allows continuing the successfully running service for environmental relevant information for chemical substances. The combination of continuously updated, comprehensive and reliable environmental data of the Federal Environment Agency (Umweltbundesamt) with InfoChem’s expertise in substance and structure handling make this application is an indispensable resource for public environmental authorities, first action forces, and governmental departments in the legislative process.

    The Harmonisation Process – Content Matters Why a Substance Information System is Successful Over 10 Years
    (Informatics for Environmental Protection - Networking Environmental Information, 2005) Menger, Matthias; Jahnke, Petra
    In most applications the focus to interoperate between information systems often concentrate on the harmonisation of technological aspect of application’s interface. The best example is the hype of XML interfaces, which let pop-up revised applications now providing the 'harmonised' standard interface. This development is good and necessary to exchange data more easily in a wider scope. The use of these standards and frameworks lays the basic for a real inteoperabilty. Nevertheless, the question of harmonising the content of information systems seems quite different. Content is understood as the information, which is described in the technical data model of the involved applications/ information systems.
