David, I played a bit with your prototype and the way of applying filters doesn't work for me. As you wrote, a filter only affects connected collections "to the right" (in the path), not collections to the left. This IMHO conflicts with the faceted filtering approach.
While looking at the publications collection I can select values from the authors facet to filter the publications. Now focusing on the authors could be understood as a zoom into on dimension of publications, i.e. their authors. Every filter which is now applied on the authors collection should now also affect the publications. An example: Given the task "find all papers from authors in Europe", an user starts looking at papers, selects people -> schools -> countries and filters by "Europe". And thinks he is done. But he is not. Now he has to find his way back again via selecting schools -> people -> papers . That is, in my opinion, confusing. So filters should affect all connected collections. Of course, the whole thing could be understood as a sequence of filters instead, but even then: if I put "papers" in, I should get "papers" out...
