AEM Assets supports
- browsing through folders and
- form-based searching for tags
Other DAM systems offer a third alternative:
In these systems the tag hierarchy would be rendered as if it was a folder and users can naturally browse through the folders. Whenever you'd "browse" to the next tag, the UI would display the assets tagged with these current tag.
Yes - in principle AEM supports that case already: You can
a) Open the filter
b) Click on a tag filter
c) Browse to the tag you want to search for
d) Select that tag
e) Submit the search form.
"Real" tag based browsing is a one-step interaction, only. You would "open" a tag from the "hierarchy" side rail - and AEM would implicitly display all assets with that tag. Imagine it as implicit search-as-you browse:
product (select * where tag ~ /product/*) - food (select * where tag ~ /product/food/*) - regional (select * where tag ~ /product/food/regional/*) - apple (select * where tag ~ /product/food/regional/apple/*)
It should be made an option if the browsing has taxonomy or directory semantics.
Taxonomy semantics means — narrowing down the search results to more specific categories as we walk down the branch in the tree. Imagine it like select * where tag ~/product/food*
Directory semantics means displaying what is exactly associated with the tag (not with sub-tags). (select * where tag = /product/food )
Many DAM systems on the market support tag-based browsing, which can be used to create multi-homed virtual directories and reduce the necessity to create live copied in DAM repos.
This is a feature that would reduce a lot of headaches when migrating from a legacy DAM system to AEM Assets,
