I just joined the controlled vocabulary list and it looks like they may have talked about this before but I don't think anyone's brought it up here. The controlled vocabulary keywords list has several fields that really don't belong as keywords; the IPTC Subject, Genre, and Scene for example. How much work would it take to allow the user to access the structured keywords dialogue from the IPTC stationary pad for the corresponding fields. Actually storing four text files (breaking the original up so that there was one for IPTC subjects, genres, scenes, plus one for everything else) and loading the appropriate one into the dialogue depending on which field the user is editing would be the ideal solution.
This is my understanding, as I'm new to all of this. If I'm mistaken please let me know.
