Well, I do have a suggestion which is probably not original but might be worth considering. And that is that I would like to see topics identified by a tree structure with the "range of coverage" being determined by where the tree stops. This would require a fairly strict convention whereby a single multipurposed item might be identified by more than one twig or leaf, but a set of items covering many of the subtopics of a given topic would be tagged (as a set) only to the branch level of its
overall scope with only the individual items tagged by the subtopics. One of my pet peeves is that this convention is not established in most of the resource catalogues that I have occasion to refer to, so a very specific search query produces a host of non specific results (and having to add "and not..." for everything except what I want is not an acceptable solution)
