My toy GEGL which evolved into a video compositing end editing application also had a by product of a versatile proof of concept XML based project description [1]. Disregarding the temporal aspects of it, it is a structure that allows for layer groups, effect layers and cloned layers. I attempted to condense it down somewhat and remove some of the mistakes in the initial implementation and tentativly called that XML structure XCF2[2]. One of the things that would remain for making this kind of format a standard is deciding upon baseline features to be implemented, and a baseline set of operations that need to be supported PNG, SVG, JPG, ICC and EXR might seem like some of the binary formats that are referenced by the catalog. 1: http://pippin.gimp.org/oxide/ 2: http://pippin.gimp.org/xcf2/ /Øyvind K. -- «The future is already here.
