Over at org-roam-ui HQ, we’ve been thinking about doing more with dates: sort your notes by most recently written, see notes that haven’t gotten much attention, generate github like activity plots etc.
Unfortunately that was not really possibly with stock org-roam, as the only info stored is the last access and modification time of the file, not the node.
To that end I wrote a small package called org-roam-timestamps, which allows you to add mtime and ctime properties to your property drawers and keep them up to date, like this
You can choose to keep a modification history, or to just keep the last mtime. I chose a filebased approach over an extension to the db structure because the org-roam db is somewhat ephemeral, in that you should be able to regenerate the complete db from the files at any point in time. Just putting this info in a new table/column would therefore not be a good idea.
As said before, the main use-case for this will be in org-roam-ui, but I’m sure someone might be able to use it for something else as well
The main drawback atm is that updating is somewhat slow and only updates the node your cursor is on at the time of saving. I might try to rework that, if someone has any good ideas (outside of the ones listed in the repo) I’ll be happy to discuss this!
