This is my partial follow-up to Jeremy's response.
A reference space is a useful concept and Imageworks will use them for AMPAS IIF implementation. The colorimetry will match the specification but how that will be arrived at will be subject to show requirements. . It is going to be a colorspace that will be tailored per production.
OCIO is being cast in ICC like terms that aren't fully relevant. OCIO lacks a color management module portion to handle the gamut mapping and other conversions done in an ICC CMM. OCIO has a different design. It is a framework. Pieces of management can be bolted together without anything 'to clever' happening. OCIO does not specify colorimetry; It is necessary to explicitly document the colorimetric meaning of your transformations. This makes OCIO simplistic and gives the control needed to create any case. OCIO provides the flexibility to implement reference spaces as colorspaces. It also leaves you fully free to define that role as you see fit allowing many individual color pipeline to exist.
