LATCH is an information architecture that covers 5 ways in which all information can be organised.
Location
The physical location in which a note was created.
Alphabet
This is simply searching for a note using its filename.
Time
When the note was created. You can put the date in the metadata, or link to the daily note in the body.
Category
What theme does a note have in common to other notes? I organise semantically with Maps of Contnent, and otherwise using tags.
Hierarchy
What are a notes parents? I use the up meta-data to link to a notes parent. How important is this note compared to others? We can use data-view queries to look at last modified.
