The reference role doesn't appear to be used anywhere inside OCIO itself. The choice of a reference space is just an choice when creating all your transforms. That said, it is a good idea to specify this role for people reading the config, and some applications "could" potentially use it (but setting it to something weird like "utility - raw" would work technically fine, it is only confusing) The suggestions in that thread of "it's the first colorspace" is probably just because the example SPI config a happen to specify their "lnf" space first. However this is mistaken - there is nothing special about the first defined space. I would suspect whoever created the ACES config misinterpreted the "reference" role as "what space to use for reference footage" The meaning of the default roles are defined here: http://opencolorio.org/userguide/config_syntax.html#roles As you say, the reference role should be set to the main ACES space, as that is what the other spaces are defined relative to These meanings should be a bit easier to find (e.g in the C++ API docs and Python bindings too) - made ticket for this,
