[ckan-dev] Custom facets: show some facets only if a certain value is selected for a “father” facet

[Steven De Costa]

I think this sounds more like a hierarchy for the first two steps. If you
attempt to accomplish it via facets wouldn't you end up relying on the
metadata values to ensure the functionality you desire?  I think this would
mean you'd need additional validation of metadata entries based on
hierarchy logic anyway...

Perhaps try to visualize this with a Venn diagram... I think you'd end up
with discrete sets within sets, then these are the actual Facets which
allow for discovery through intersects.

Apologies if I've missed something and my comment simply adds confusion ;)

Cheers,
Steven
