The MIT Haystack project released some preliminary code. If RDF is a grand unified theory of information, Haystack is the universal RDF browser. The Eclipse-like UI eschews dialog boxes for an array of panes; this cleverly eliminaties modality. It’s also surprisingly polished for an academic research project. Potential hackers beware; I suspect much of the code is written in Adenine, the secret love-child of Python and RDF. [Hack the Planet]
