The EXPERIMENTAL area of my KNIME spaces is where I keep components that I consider can be made available for public release, but are likely to be subject to additional refinements or modifications because I am still experimenting with how they work. That's not to say that I expect them to have any problems, but simply that they are based on "ideas-in-progress". Feel free to use them, but beware that they may be more likely to receive functionality changes than the components that I release in my general Public space.
