16.1 How do I have more than one Org-roam directory?

Emacs supports directory-local variables, allowing the value of ‘org-roam-directory’ to be different in different directories. It does this by checking for a file named ‘.dir-locals.el’.

To add support for multiple directories, override the ‘org-roam-directory’ variable using directory-local variables. This is what ‘.dir-locals.el’ may contain:

((nil . ((org-roam-directory . "/path/to/here/"))))

All files within that directory will be treated as their own separate set of Org-roam files. Remember to run ‘org-roam-db-build-cache’ from a file within that directory, at least once.
