Hi, I'd like to mention that none of the proposed formats except the XML approach would be capable of supporting the stuff we want to add to GIMP with GEGL. I don't think any existing format could be sanely extended to support complex render graphs as will be introduced with GEGL. We are not talking about simple layer lists or trees any longer but we need to be able to store complex processing intructions with each node. XML seems to be the only reasonable choice here. According the library that reads and writes the new format, GEGL should provide this functionality. The basic file format should be defined by GEGL and GIMP will only add some user interface specific things in its own namespace. Sven
