DMX is a platform for knowledge management and collaboration. The unique feature of DMX is the **situation-centered** user interface. You have quick access to all your data with its meaningful relations without cluttering the interface. Whether your information is text, images, documents, web pages, events, contacts or any custom types you have modelled for yourself, you can access, edit and moderate them all in the DMX web application running n your browser. DMX represents information contexts as a network of relationships. This graphical representation exploits the cognitive benefits of mind maps and concept maps. Visual maps -- in DMX called **Topic Maps** -- support the user's process of thinking, learning, remembering and generating ideas. A topic map shows what you are focusing on by separating the content from it’s views and giving the user the control for revaling only meaningful information for the task at hand. We claim that working with DMX stimulates creativity and increases productivity.
