I noticed that one of the Longwell demos had a couple of ways to view dates, thanks. In fact, that's what led me to ask if Longwell supported hierarchical facets in the first place.
I was attracted to Longwell because of its ability to automatically work out ways of navigating RDF. Maybe it's because the semantic web is still so young but I have yet to see a project which can cope with data consisting of thousands of facets AND is able to present them in a usable gui. I think Eyal Oren's browserdf.com (which unfortunately is down at the moment) is very promising. He has an algorithm for ranking facets and can therefore present those which are more 'interesting' to the user. His paper is here... http://citeseer.ist.psu.edu/cache/papers/cs2/281/http:zSzzSzeyaloren.orgzSzpubszSziswc2006-facets.pdf/oren06extending.pdf Facets are fascinating and as computer scientists we have a heck of a lot to learn from librarians! I'm currently examining the Bliss Classification (BC2). The librarians that created this general subject classification have spent nearly forty years creating it and they aren't finished yet!
