Yannis Tzitzikas is a name
Yannis Tzitzikas is a name you will be hearing more from if you're interested in where faceted classification is going. Beyond Ranganathan, I can tell you that. He has a bunch of fascinating papers on his site, and send me another one (not available from his site), called An Algebraic Approach for Specifying ompound Terms in Faceted Taxonomies (PDF, 200K), which talks about how to impose limits on the combinations you can make in a faceted classification scheme. I have to study it: I'm not sure if this also solves the problem of dependent facets (where one facet is only applicable if certain topics of another facet have been selected).
