I keep taking about wanting to use markdown files for contacts and policies at work, stored in reports repos for change tracking. The problem is always “the legal team isn’t going to use Git”. What I’d love to see is a front end for Git that allows direct markdown editing and emulates the Track Changes feature in Word.
I’ve been doing a lot with organizing my data in Obsidian, and I’ve found utility in having both folders and metadata. Using the Dataview plugin makes proper metadata fields really powerful; you basically turn your collection of markdown files into a NoSQL DB. Having a folder structure is handy too though because you can have different metadata templates applied to new files in different folders with the Templater plugin.
Obviously that is dependent on a fairly specific workflow, but I think it’s worth considering “why not both?”
