Pedigree is a hobby operating system, primarily designed by James Molloy and Joerg Pfahler, and currently maintained and implemented by Matthew Iselin. An additional contributor of note is Eduard Burtescu, who particularly aided in implementing USB.
The Pedigree Project aims to develop a solid yet portable operating system from the ground up with an object oriented architecture where possible. The goal is to support multiple different subsystems to allow many different applications to run natively on Pedigree. Further goals include portability across multiple different architectures (x86, amd64, PPC, MIPS and ARM), a unique graphical user interface, and support for a variety of popular driver interfaces to improve hardware support.
