Extending Hierarchy Module / Configuring Resource Pages

[ppr]

@nxm

The way the Hierarchy model works makes sense to us - a node in the hierarchy is (sometimes) an Item Set. In the context of archival description, a fond or series or file is a thing in and of itself (with metadata) and also only exists because it is an “item set”.

So, our plan is to have the metadata — not just the Items list - display when you click on a node that is and Item Set. Basically to one side (left or right) you have the hierarchy and as you click on nodes the corresponding metadata displays.

I have the same issue. If you use Hierarchy module to display archival collection, you will have important metadata at each level of the Hierarchy and each level will be one item-set.

Fonds
- sub-fonds
  - serie
     - sub-serie
        - folder/file

So we need a way to display this archival metadata for each level/item-set.

In the way the module currently works, it does not display metadata of item-set level but allows to browse items where there are located in the hierarchy (which is also nice).

It seems to me there are two options discussed below:

1. Allow Hierarchy module to link to the item-set pages instead of the https://xxx.com/s/site/hierarchy/## pages. Hierachies are displayed on the item-set pages so we are not completely leaving the hierarchy. If this solution is chosen it would be nice to have it as an option (because the other view is also something users can want).
2. Modify the view provided by Hierarchy module (https://xxx.com/s/site/hierarchy/## pages) to include metadata from the current item set. I think this is what nxm had in mind when speaking of a “Finding Aid resource page” or "resource block for “Item Set with metadata”. I am not sure this is the way because there is already an item-set configuration page on the theme settings (/theme-resource-pages#section-item_sets) and it would be difficult maybe to distinguish item-set used in hierarchies from other item-set.

The simplest solution seems to me to do 1 as everything is already in place to customize item-set pages in theme settings.
