I often want to organize tags into an ontology, i.e. there are categories of tags, and a category can itself be a parent tag that includes all its children
As a toy example, someone keeping their recipes in Dynalist might have the tags
#banana
#apple
#orange
#fruit
#milk
#banana
, #apple
, #orange
are all examples of #fruit
. It would be useful to have the tags organized like
-
#fruit
**#apple
**#banana
**#orange
#milk
so that when searching for #fruit
, we get everything that is tagged with any of #fruit
, #apple
, #banana
, #orange
. This avoids having to keep track of the entire ontology and manually applying all the relevant tags every time you tag something. Instead, you can apply only the most-specific tags you need and rest assured that the parent tags will follow along.
