I've started a very rudimentary tree effort in . I'm still on top level items. I think we don't have to expand on all of them. Some like Genre will need to go one level down, as they may be very complex. We should mostly clear out a set of standard cats for all films (year -language -country -genre). Some are often doubled by another template: for example, if a director's filmography template is present, it's a repetition to add By director in the cats. Yet apart from a general outline and guidelines, Dept Categorization should be where categorizing tasks are coordinated. For example we could ask for an AWB user to run through a particular list and seed some categories. Or we can decide how to organize best the tree. Happy Holidays.
