- KonferenzbeitragBusiness Models for Open Source Projects in Environmental Informatics(Environmental Informatics and Industrial Ecology, 2008) Ciroth, Andreas; Moeller, Andreas; Page, Bernd; Schreiber, MartinGenerating a healthy business model is one of the main challenges when setting up an open source project. In this presentation, I will explore how sound, healthy business models for open source projects can look like, with a focus on environmental informatics. I will do so by first analysing which elements of open source projects exist that can, potentially, generate turnover, and will then estimate the relevance of these different elements, for different types of projects, taking into account costs and other efforts. This will be illustrated by several cases, including the openLCA project where I am involved in myself. Result of this is an overview of types of business models of successful open source projects, that each deploy means that fit best to their specific situation. Result is further that these business models frequently do not follow a common pattern; finding these requires often a wider view of analysis, and more creativity, and under certain circumstances, business models are likely to fail. These critical circumstances will be highlighted, as to be carefully avoided when tailoring a new project. I will conclude with a tentative outlook on further development of the identified project types.
- KonferenzbeitragOdyssey to Kalypso – Experiences with Setting Up an Open Source Platform for Environmental Modeling(Environmental Informatics and Industrial Ecology, 2008) Belger, Gernot; Haase, Michael; Lippert, Kaj; Moeller, Andreas; Page, Bernd; Schreiber, MartinIn recent years a large number of open source solutions emerged which are of special interest to Environmental Informatics. Open source is now no longer just a playground of universities, research institutes and committed individuals who are communicating via the Internet to make ideas come to reality. Open source is also increasingly reflected in the business models of small and medium seized enterprises as well as well-known large IT companies. Different viewpoints on the issue of open source software from the Open Source Initiative and the Free Software Foundation are presented and analyzed. An introduction to open source license categories is given and compatibility issues of popular and widely used open source software licenses are discussed. The paper also introduces to basic strategies how to set up an open source project. A certain charm lies in the creation and establishment of one’s own open source project. This paper presents the story (Odyssey) of the open source project Kalypso (http://kalypso.sourceforge.net/). Kalypso encompasses a software palette for water resources modeling (e.g. hydrologic and hydraulic models) which was built on the basis of the powerful Kalypso framework. This framework allows to build extensive decision support and information systems including among others spatial data management and analysis, time series management and analysis, generation and management of reports, database access and accessing existing executable numerical models from the fields of environmental and water resources modeling. The paper introduces to the Kalypso project and presents the work spent to publish Kalypso on an open source platform.

- KonferenzbeitragInteroperable Routing Services in the Context of Evacuation Schemes due to Urban Flooding(Environmental Informatics and Industrial Ecology, 2008) Albert, Holger; Belger, Gernot; de Camargo, Vinicius; Haase, MIchael; Lippert, Kaj; Neis, Pascal; Pasche, Erik; Zipf, Alecander; Moeller, Andreas; Page, Bernd; Schreiber, MartinClimate change scenarios predict an increasing frequency of extreme flood events in coastal areas. Many big cities in North-Western Europe are located within the reach of these floods. Flood protection schemes have been built and enhanced everywhere. But a residual risk exists that these flood protection schemes will fail and the areas behind these structures will be flooded severely. Within the last decades many of these cities expanded significantly into former floodplain areas as well. Building complexes within harbor areas which served as store- or warehouses in former times are now being transferred to high end business and living facilities. These structures have always been subject to the thread of flooding due to the proximity to open waters. Against this background, means for disaster management in the context of extreme flood events are being paid high attention on all administrative levels. The main objectives of these activities among others are to save people’s and other creature’s lives as well as to avoid en- vironmental hazards, e.g. due to spilling of hazardous chemicals, and to avoid assets to be destroyed. In order to design evacuation schemes for different flooding scenarios evacuation paths need to be determined for every building in the potentially flooded areas. The times for flood mitigation as well as travel and “get ready to go” times among other details need to be taken into account in this context. Routing Services provide means for determining travel routes and travel times on the basis of a predefined street network. Dynamically expanding inundated areas need to be excluded from this street network for route searches. The Open Geospatial Consortium (OGC) has specified Routing Services as part of Open Location Services which have been implemented by the Cartography Research Group at the University of Bonn. This paper introduces into disaster management due to urban flooding as well as to OGC’s OpenGIS Location Services with special emphasis on Routing Services. An example for utilizing Routing Services in order to identify critical evacuation paths (Bottleneck Analysis) is presented. The paper documents the results of a close collaboration in the research projects “RIMAX” and “OK-GIS” which are both funded by the German Federal Ministry of Education and Research (BMBF).
- KonferenzbeitragPYHASSE a New Software Tool for Partially Ordered Sets Example: Ranking of Contaminated Regions in the Alps(Environmental Informatics and Industrial Ecology, 2008) Voigt, Kristina; Brüggmann, Rainer; Schramm, Karl-Werner; Kirchner, Manfred; Moeller, Andreas; Page, Bernd; Schreiber, MartinIn complex environmental data-sets it is often necessary to compare different sets of criteria (attributes). In the similarity analysis which is part of theory of partially ordered sets (Hasse Diagram Technique) we intend to calculate the similarity of different posets. This similarity analysis is an important feature of the newly developed software packages called PYHASSE developed by the second author. As an example we use a data-matrix which was generated in an international project named MONARPOP (Monitoring Network in the Alpine Region for Persistent and other Organic Pollutants) in which selected chemicals in environmental media in the mountain area of the Alps were analyzed in the years 2004 and 2005 (MONARPOP, 2008). 17 pesticides were chosen and analyzed in soil samples in Germany, Austria, Switzerland, Italy, and Slovenia. The samples were taken at different heights. In this approach we took a look at soil samples at different heights in the five mentioned countries. Two soil types were analyzed: humus and mineral soil layer. So we perform a similarity analysis of the two different soils (humus and mineral soil) in order to get an idea if the type of soil has a great impact on the ranking of the pesticides and hence on the contamination. It is demonstrated that the different soil layers have some kind of influence but not a great impact on the structure of the Hasse Diagrams.
- KonferenzbeitragAdaptation Planning Framework to Climate Change for the Urban Environment in Ho Chi Minh City(Environmental Informatics and Industrial Ecology, 2008) Storch, Harry; Schmidt, Michael; Moeller, Andreas; Page, Bernd; Schreiber, MartinThe overall objective is to develop and incorporate adaptation into urban decision-making and planning processes with designation criteria and zones that will lead to an increase of resilience to climate-related physical and social vulnerabilities of the urban system of HCMC. Climate Change will likely change current climate conditions and lead to an ongoing sea-level rise and increase in extreme weather events such as heavy rainfall and heat waves etc. These climate related events cause a multitude of potential impacts and risks not only to natural areas but specifically to populations of densely built up metropolitan areas. In foreseeable future they may also cause indirect negative effects such as severe urban floods or disturbances of the energy supply or public transport systems in urban areas. The main task of assessing climate change related impacts in urban areas is to estimate the possible damages that might arise for human-influenced systems by climate change, including extreme weather events. In general there are two elements that define the potential risk: first, the probability of the occurrence of the events and second the “elements” at risk. Events to be included are heat waves, heavy rain, floods etc. "Elements” at risk are not only assets like houses, urban infrastructure services or economic losses, but also human health and livelihood.

- KonferenzbeitragDevelopment of an Open Source Software Framework as a Basis for Implementing Plugin-Based Environmental Management Information Systems (EMIS)(Environmental Informatics and Industrial Ecology, 2008) Wohlgemuth, Volker; Schnackenbeck, Tobias; Panic, Dominik; Barling, Robert-Lee; Moeller, Andreas; Page, Bernd; Schreiber, MartinThe software-sided support of state of the art problems in the area of environmental management information systems (EMIS) generally leads to redevelopment of often used basic functionalities before implementation of the intended functions, which focus on the problem under investigation. This affects components regarding a certain aspect (e.g. material flow analysis or simulation runs) as well as software-related infrastructure components e.g. GUI, logging or persistence. Within the EMPORER project, supported by the German Federal Ministry of Research and Technology (BMBF), an extendible and component based software platform is developed. Based on this software platform there will be some components and applications developed for the fields of material flow management and simulation as a proof of concept. Thus, the objective of this development is to offer an easy to use tool kit and framework which can seamlessly be extended by components with a close-to-the-problem functionality. To bring forward further development and distribution, the platform will be made available as an open source software framework enabling further methods and components to be complemented by third parties. This paper describes the basic architecture and the fundamental extension possibilities of the software platform which is based on Microsoft’s .NET.
- KonferenzbeitragA Plugin-Based Framework for Domain Models and Persistence in Environmental Management Information Systems(Environmental Informatics and Industrial Ecology, 2008) Busse, Thorsten; Denz, Nicolas; Page, Bernd; Moeller, Andreas; Page, Bernd; Schreiber, MartinIn this paper, we present an open source framework that supports the implementation of persistable domain models in dynamic plugin-based architectures on Microsoft .NET. The framework includes a domain model service that allows plugins to provide new domain types to other plugins as well as to use, extend, and observe domain objects contributed by other plugins. Furthermore, a persistence service is provided as an abstraction from concrete repository implementations. The paper discusses our solutions to the challenges of persistence in dynamic architectures, presents an exemplary domain-specific language for material flow analysis, and compares our work to related approaches from the common software platforms .NET and Eclipse. Though the framework is in principle application- independent, we apply it primarily in the context of environmental management information systems.
- KonferenzbeitragHow Green is the Web? Visualising the Power Quality of Websites(Environmental Informatics and Industrial Ecology, 2008) Naumann, Stefan; Gresk, Sascha; Schäfer, Kerstin; Moeller, Andreas; Page, Bernd; Schreiber, MartinVisualizing the quality of a product or a service regarding its environmental impact is an important step to foster sustainability. Since Internet and Information Technology have an increasing consumption of power, it is interesting to visualize if a Website is hosted with green electricity. We developed a prototypical Firefox extension, which depictures this power quality. The service bases on a database where several providers are stored who offer hosting with green electricity.
