urpmi was developed as an experimentation by Pascal Rigaux (Pixel) to address RPM install limitation, it was further maintained by François Pons and different Mandriva employees. It is currently (2010-2013) maintained by Thierry Vignaud which was the maintainer of rpmdrake (see ) and of one of the co maintainer of the drakx installer and tools at Mandriva before continuing doing that job at Mageia. This is the version that will be used by Mandriva in its future products which will be based on Mageia (See ).
Per Øyvind Karlsen maintains a fork of urpmi at Rosa Linux, backporting fixes & improvements from Thierry Vignaud work (e.g.:  -> ), but this is not the version used by Mandriva Business Server which is based on Mageia.
