So LMU is entering the race for best data analysis tool I guess. Competing with well known frameworks such as Weka, RapidMiner, KNIME, Rattle/R will be tough. Unfortunately, there are no pre-build packages available so far that I could give it a try.
Recently, I've been doing a lot of work in KNIME (which is also based on Eclipse) and enjoyed it a lot. In fact, the framework is designed so well that it is shockingly easy to write your own plugins for it (partially thanks to the Eclipse platform). The only downside is that it is only kind of open source similar to Android, i.e. the main development takes place behind closed doors and every now and then they publish a new release together with the sources. It seems that Knowing tries the open-all-the-way approach which I'd prefer. I wasn't able to find out how it is licensed, though.
Although competition and more so convincing users will be challenging to say the least, I applaud the effort to do actual top-notch software development beside the usual scientific work. Can't wait to try it out once pre-build versions are available.
