"VIRTUOSO projects aims at providing European Security stakeholders with a toolkit based on an open-source-software framework and a set of advanced information processing tools. This toolkit will allow building end-user oriented applications: - Ranging from open source collection to decision support - Providing at each step actionable, rated, validated information - Integrated in an open framework in order to accept existing or future tools - Compliant with legal & ethical issues The VIRTUOSO toolkit will increase user productivity by automating time consuming activities and eliminating current bottlenecks that will be accurately identified with a large panel of users. Due to numerous application domains and the various size of the resources needed by the application of such a toolkit, this toolkit will demonstrate high level scalability, from mobile to High Power Computing systems. Cooperation of various European agencies will be addressed by proposing a standard, open and Interoperable toolkit, facilitating storage and sharing of information. Guidelines will be proposed."
