COLLADA (from
collaborative design activity) is an interchange for interactive
3D applications. It is managed by the nonprofit technology consortium, the
Khronos Group, and has been adopted by ISO as a publicly available specification, ISO/PAS 17506.
COLLADA defines an
open standard XML schema for exchanging
digital assets among various graphics
software applications that might otherwise store their assets in incompatible file formats. COLLADA documents that describe digital assets are XML files, usually identified with a.dae (digital asset exchange).
