This is likely a very old request.
I am charged with setting up a global config for a new startup.
I am basing the .ocio on aces1.0.3
I'm confused on how to customise profiles, looks etc ... I do not need half of the colourspaces, ie; dolby ...
Any advice from all of you would be greatly appreciated !

Not sure if you got help here Markel.
I managed to craft up a spreadsheet that should work. Should being that it
hasn't been tested extensively and that you'll need to manually make your
OCIO stanzas from the provided entries. This isn't nearly as terrific as
Colour, but I realize not everyone has Python handy, and a sort of "online
calculator" probably couldn't hurt as I found myself doing the adaptation

I've input the values you gave along with ACES AP0 primaries. The chromatic
adaptation is the Bradford CAT. The OpenColorIO stanzas appear on the final
three lines. Those should be suitable to copypasta into a configuration as
part of a group transform. Note that your source buffer will need to be
linearized however appropriate for your encoded image.
Let me know if anyone spots a mistake.

I checked for the first (to new primaries) and third (to ACES) Matrix Transforms and they match conversion of the colorspace to XYZ. I did not check for the middle XYZ adaptation Matrix (my spreadsheet doesn’t include that.)
