Tony Parisi one of the co-creators of VRML, reviews "COLLADA: Sailing the Gulf of 3D Digital Content Creation". Quoting from the review: "...the laser-focus of the COLLADA design team seems to have paid off: the industry now has a common exchange format for game assets, and there is hope yet for developers who would rather spend their time building games than building tools to make games. This clarity of focus on the design comes through in the book as well. ... A detailed and lucid book that explains COLLADA from concept through implementation. If you are a programmer with a reasonable understanding of 3D graphics programming and/or authoring using 3D scene graphs, you will be able to learn the basics of COLLADA. If you are an experienced 3D toolmaker, COLLADA contains everything you need to get up and running to build your game, game engine or content pipeline tool. If you are a manager or decision maker, you get the added comfort of knowing that — finally — you just might be able to write that tool once and not over and over again."
