COLLADA (COLLAborative Design Activity) is an interchange file format 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) filename extension.
Originally created at Sony Computer Entertainment by Rémi Arnaud and Mark C. Barnes, it has since become the property of the Khronos Group, a member-funded industry consortium, which now shares the copyright with Sony. The COLLADA schema and specification are freely available from the Khronos Group. The COLLADA DOM uses the SCEA Shared Source License.
Several graphics companies collaborated with Sony from COLLADA's beginnings to create a tool that would be useful to the widest possible audience, and COLLADA continues to evolve through the efforts of Khronos contributors. Early collaborators included Alias Systems Corporation, Criterion Software, Autodesk, Inc., and Avid Technology. Dozens of commercial game studios and game engines have adopted the standard.
In March 2011, Khronos released the COLLADA Conformance Test Suite (CTS). The suite allows applications that import and export COLLADA to test against a large suite of examples, ensuring that they conform properly to the specification. In July 2012, the CTS software was released on GitHub, allowing for community contributions.
