Furthermore, the colorimetric properties of the Cineon color space itself are IMO not specified clearly either. The 10-bit log encoding seem to be specified in terms of "printing densities", where "Printing Density = the density above D-min of the negative as seen by the combination of print film and the illumination of a standard motion picture printer" (according to http://www.kodak.com/US/plugins/acrobat/en/motion/support/dlad/kodak_digital_lad_users_guide.pdf).
I think you'll find it is film color densities. The mapping to CIE is complex (I think I remember someone talking about this very problem at last years CIC. It involved a lot of work characterizing existing film stock.) Cineon is effectively just a "digital film" intermediate format, intended for converting film to digital and back again, not for interchanging with other digital media. That's doesn't mean it's not possible, it just means it's not easy.
