Quoting http://openrecord.org/about.html :
 * Status (as of November 2008)
 * OpenRecord is continuing as an ongoing Dojo Foundation project. In November 2008 we started working on a new version of OpenRecord. In our Subversion repository, this new OpenRecord Redux code lives side-by-side with our original OpenRecord Classic code. OpenRecord Redux uses the current Dojo 1.2 release, including the latest version of the Grid widget.
