Just to follow up on Danny's comment: our approach is metadata-based by
default, but can be used as Danny states below to implement faceted search.
The demo Mark links to is not very faceted in the traditional sense that I
believe John is speaking of. We're finding that in practice, there is a
continuum from simple Dublin Core type metadata search to truly faceted
applications, and that, as Danny says, representing range distinctions in
the facets helps to bring the faceted aspects of a given application to the
