 ====== Breadcrumbs output by the taxonomy_context module ======
-  * what should their content be ?
+===== what should their content be ? =====
+==== Nedjo ====
+/09/18: Breadcrumbs in Drupal lead up to, but do not include, the current page. Assume a taxonomy like this:
+<code>
+Food (vocabulary id 2)
+  grains (root term, id 1)
+    wheat (second-level term, id 2)
+    rice (second-level term, id 3)
+  vegetables (root term, id 4)
+    potatoes (second-level term, id 5)
+    onions (second-level term, id 6)
+</code>
+When browsing the term 'rice', I assume the breadcrumb should be:
+[[/|home]] > [[taxonomy/vocabulary/1|food]] > [[taxonomy/term/1|grains]]
+When browsing a node assigned to rice, the breadcrumb should be:
+[[/|home]] > [[taxonomy/vocabulary/1|food]] > [[taxonomy/term/1|grains]] > [[taxonomy/term/3|rice]]
+We should probably look at the [[http://drupal.org/project/taxonomy_breadcrumb|taxonomy_breadcrumb module]] for comparison.

+/09/18 I'm a bit reluctant on this. One the one hand, ISTR that breadcrumbs in drupal are supposed to as you describe. OTOH, there's a [[http://drupal.org/node/64067|snippet]] to include the page title, which means it is felt as needed and, maybe more importantly, Steve Krug, in its oft-quoted "Don't make me think" book about web usability, insists on including and even boldfacing the last item in the breadcrumbs, and I think this advice is as good as most of the book (I hear even Dries has it). To illustrate this example I'd say that browsing "rice" should give
+[[/|home]] > [[taxonomy/vocabulary/1|food]] > [[taxonomy/term/1|grains]] > rice
+and show a page related to the terms rice, typically the list of nodes matching the term. while browsing a node assigned to rice, say Carnaroli, the breadcrumb should be:
+[[/|home]] > [[taxonomy/vocabulary/1|food]] > [[taxonomy/term/1|grains]] > [[taxonomy/term/3|rice]] > Carnaroli
+... which happens to be how drupal works from the home page, which by default displays a node list matching a criterium (published + promoted), from which each node is one level deeper as a detail page. Same with these taxonomy contexts: term page lists nodes, putting the node list in its parental context, and node pages show the nodes, in their parental context.
+or possibly
+[[/|home]] > [[taxonomy/vocabulary/1|food]] > [[taxonomy/term/1|grains]] > [[taxonomy/term/3|rice]] > [[http://example.com/carnaroli_permalink|Carnaroli]]
+to include automatic permalinks within the same logic
+==== Current situation ====
+  * using the latest patch by FGM on top of 4.7.3, the situation is mostly the one I describe, but this leads to a peculiar path on the taxonomy/vocabulary/<vid> page : the breadcrumb currently becomes :
+[[/|home]] > [[taxonomy/vocabulary/1|food]] > food
+  * in this situation, it should probably just be :
+[[/|home]] > food
+==== Other P.O.V. ? ====
+Any other ideas ?
+==== Vote list ====
+Add your preference to your choice:
+  * No terminal symbol (default drupal style)
+  * Terminal symbol (usability style)
+  * Setting to choose either
