    Open Source Tools for Enterprise 2.0: A Feature-Based Adaptable Analysis
    When introducing Enterprise 2.0 tools to support knowledge workers working together on cognitive tasks and sharing information, companies and organizations face the problem of choosing the right tools from a huge market of systems. In particular for SMEs, open source tools for Enterprise 2.0 offer a good alternative to commercial systems, but the diversity of systems makes this marketplace quite confusing. Therefore we present a study of the growing market for Enterprise 2.0 systems that focuses entirely on systems available under an open source license. We use a set of 97 individual features and criteria that are grouped around the central functionalities of communication, coordination, collaboration and connection, to analyze the suitability of a representative sample of open source Enterprise 2.0 tools for the average knowledge worker. The evaluation matrix can be easily adapted to get more specific evaluation results for more particular company requirements. Our results show that there are many technically mature solutions with a broad range of functionality available from the market of open source tools for Enterprise 2.0.

    Remote On-Screen Support and Cooperation with Open Sporce Components in e-Learning
    (E. Weber, 2008)
    In many learning situations it is essential to offer support for the students by an instructor directly at the computer screens of the students like in a computer lab. To provide this support in remote e-learning situations, the teacher needs a real-time view of the contents of the students computer screen from remote. in this paper we discuss a solution for providing real-time remote on-screen student support with distance-learning via internet connections in a safe and secure manner. Our "virtual classroom" consists of open source components only and workson most operating systems independently of the underlying learning software used. We enhance this solution with a prototype of a common desktop, that is suitable for small work groupsto work together on a common computer screen in real time, which is useful e.g. for small student groups working togetherfrom remote. The common desktop systemalso works independently of the software used on the screen and can be operated with any client computer. In practice, these solutions are accompanied by commuication systems like chat or voice-chat, to achieve a system for real-time remote teaching and real-time remote cooperation.
