How to assign keywords to Phaseone iiQ files

Hi,

I have a good workflow for Canon .CR2 in operation since 8 years now, it is stable.

Basically I organize my files in a folder structure and assign keywords with bridge. Keywords are assigned in Bridge, since I can just pick from a predefined list, which is quick and prevents typo errors.

Now I also shoot with phaseone. How can I assign Keywords here (I mean not typing them, but assigning them from a structured list)? Bridge is (I think) not the tool of choice, since I can't get the Information from the .xmp back to Capture One (which is my raw converter & partly organization tool). In Capture One I do not have predefined structured lists so I have to type every single keyword :-(

DNG does not make sense with Phase One I think, since Capture One is pretty bound to the original iiq raw format.

Is there anybody out there with a good .iiq workflow including keywords. There are other issues with an .iiq workflow (file organization) but let's keep it to the keyword issue for the moment.
