** Org Roam
|
||||
|
||||
#+call: confpkg()
|
||||
|
||||
When I started out using Org mode, I just used vanilla Org files to manage my
|
||||
notes. This worked, but as my notes grew more and more I've begun to
|
||||
increasingly rely on [[https://www.orgroam.com/][Org-roam]] to more systematically manage my organization.
|
||||
|
||||
*** Concept
|
||||
|
||||
Org-roam is inspired by Roam Research, and like that tool it is based on the
|
||||
Zettelkasten (slip-box) note-taking method. In the Zettelkasten method, notes
|
||||
and concepts are separated into small chunks (called "nodes" in Org-roam
|
||||
terminology). These notes can live freely in any file on your system, and are
|
||||
linked to each other through ID links, leading to a freer note system that isn't
|
||||
tied to any particular organizational structure or hierarchy.
|
||||
|
||||
*** Task Management
|
||||
|
||||
In my use of Org-roam for task management, I divide nodes into a few different
|
||||
categories:
|
||||
|
||||
1. *Areas*, which represent continual areas of your life to organize and plan;
|
||||
2. *Goals*, short- or long-term, things that can be completed;
|
||||
3. *Tasks*, which are one-time and contribute to goals or areas.
|
||||
|
||||
Areas are stored as subnodes of the =Areas= file node, and likewise for goals.
|
||||
They also have the =:area:= and =:goal:= tags respectively. A task is a node that is
|
||||
a TODO entry that links to an area or a goal. We can thus check for if a node is
|
||||
a task by checking if the node links to a =:area:= or =:goal:= tagged node.

||||

||||

*** Roam Buffer
|
||||
|
||||
The unlinked references section is turned off by default for performance
|
||||
reasons, but I've never had any serious issues with it. Let's turn that on, and
|
||||
also make sure backlinks are unique.

*** Roam Capture

Creating new nodes should be quick and easy, so we should stick to one template
|
||||
to avoid the hassle of choosing.
