Collada is the name of a 3D interchange file format.
“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) filename extension.” (Wikipedia, retrieved 22:15, 7 May 2009 (UTC))
But some applications, like Google Earth have adopted Collada as native file format to represent artifacts that one can "pose".
