I have long resisted a deep dive into the app Obsidian, but a couple of days ago I took the time to set up a vault an fill it with content. Surprisingly, the feature that created the most fascination is a recent addition: document properties.
I’ve always been a meta-data nerd in all note-taking approaches I have worked with so far. There is no other solution that comes even close to what Obsidian provides. Meta-data are not just treated as text. It is possible to define the type of a piece of meta-data in terms of whether it can be a list, a number, or even a checkbox.
I’m still just starting to find out what can be done using this feature. But it alone may be enough to make me switch to Obsidian wholesale.
