5.3 File Refs

Refs are unique identifiers for files. Each note can only have 1 ref. For example, a note for a website may contain a ref:

#+title: Google
#+roam_key: https://www.google.com/

These keys come in useful for when taking website notes, using the ‘roam-ref’ protocol (see Roam Protocol).

Alternatively, add a ref for notes for a specific paper, using its org-ref citation key:

#+title: Neural Ordinary Differential Equations
#+roam_key: cite:chen18_neural_ordin_differ_equat

The backlinks buffer will show any cites of this key: e.g.
