The Org-roam Node ​

We first begin with some terminology we’ll use throughout the manual. We term the basic denomination in Org-roam a node. We define a node as follows:

A node is any headline or top level file with an ID.

For example, with this example file content:

orgmode
:PROPERTIES:
:ID:       foo
:END:
#+title: Foo

* Bar
:PROPERTIES:
:ID:       bar
:END:

We create two nodes:

  1. A file node “Foo” with id foo.
  2. A headline node “Bar” with id bar.

Headlines without IDs will not be considered Org-roam nodes. Org IDs can be added to files or headlines via the interactive command M-x org-id-get-create.
