MindRaider is a “mind mapping” application that uses RDF as it’s native representation. It’s an open source software project developed in Java by Czech programmer Martin Dvorak . The concept of a mind map is a simple one, but I’ve found it to be very useful over the years for organizing my thoughts. There is a natural fit with RDF and, in fact, any graph based representation. I’m not sure yet how MindRaider is taking full advantage of RDF, but the possibilities are intriguing. (spotted on ltu).
