In this paper we describe the Multimedia Documentation Lab (MDL1), a system which is capable of processing vast amounts of data typically gathered from open sources in unstructured form and in diverse formats. A sequence of processing steps analyzing the audio, video and textual content of the input is carried out. The resulting output is made available for search and retrieval, analysis and visualization on a next generation media server. The system can serve as a search platform across open, closed or secured networks. MDL can be used as a tool for situational awareness, information sharing or risk assessment, allowing the integration of multimedia content into the analysis process of security relevant affairs.
