By the looks of it, SVG seems like the 2D doppleganger of COLLADA:
-They both have XML-based DOMs
-They're both quite complex interim formats
-Both seem to be open formats aimed for wider support application support than other formats of their kind
How suitable is SVG for animation? I've read that it's mainly for static images, but then I've also seen information that could be for animation manipulation for SVG 1.1, but I'm not quite sure. I'm on a vendetta for finding an open, vector-based solution for generating computer graphics for 2D games since rasterized graphics, although have their advantages over vector graphics, are just too memory-instense for my purposes.
