[Bf-committers] Collada status

[Rodrigo Hernandez]

Hi Ton,

The problem I found with the current Illusoft scripts is that they are 
parse the COLLADA "manually", meaning they access the file as pure XML 
through expat, which makes updating to later specification versions and 
adding functionality very tedious and time consuming.

If you want to keep the functionality as scripts I would suggest at 
least getting a hold of some implementation of COLLADA_DOM or FCOLLADA 
Python bindings/extensions (which sadly don't seem to be available), and 
migrate the current parsing code to that.

Regards,
Rodrigo Hernandez.
