The Distributome Project is an open-source, open content-development project for exploring, discovering, navigating, learning and computational utilization of diverse probability distributions, which are functions that assign probabilities to events and give rise to mass or density functions, distribution functions, quantile functions, probability and moment generating functions.

The current Distributome XML meta-data on distribution properties and inter-distribution relations is available here and the current XSD schema is available here. The complete Distributome project Java source code is available online under LGPL license. The applet binary JAR files and the HTML wrappers are also available.
