OpenRaster is an effort by the Create project[1] to offer a standardized and open interchange format for raster-based applications. MyPaint and Drawpile (SVN version) uses this format by default, and Krita and gegl should be able to use it. Now GIMP can too!
The plug-in is attached. Move to GIMPs plug-in directory to install.
Its a part of the oratools project, which aims to provide useful tools and utilities to facilitate the use of OpenRaster file format. You can find it at http://gitorious.org/oratools
