---- start of mind dump ----
I don't know if I'm starting to hate XML, but I am at the moment editing
a music video in vim, doing compositing in xml, and it is no fun. So
I'll be lax on the syntax of xml transformation of my mind.
What would be exported is a model api,. the GimpImage model,. which is
constructed using gegl.
The data stored in the GimpImage models data store is as follows:
make a mental %s/GimpGroup/GimpLayer/g or gimplist or whatever is
pleasing,. this is a mental draft trying to translate some other
internal datastructues.

At least I have some of my thoughts shared now,. hopefully in an
attackable manner.
