A reference for the metadata fields used on pieces of writing here. Section headings are the literal frontmatter keys (except reading-time, which is computed and not stored in frontmatter).
Fields
date
When the piece was first created. Shown as “Created
modified
When the piece was last meaningfully updated. Shown as “Updated date by more than a day.
If you don’t set this in frontmatter, Quartz infers it from git history. Any commit touching the file updates the date — there is no “meaningful change” threshold. To freeze the value, set modified: explicitly in frontmatter.
reading-time
Auto-computed from the page text using the reading-time package, at roughly 265 words per minute. Shown as “N min read” in the metadata header. Not a frontmatter field; the only knob is the body text itself.
Clicking the value jumps to All pages sorted shortest first.
importance
A 1 to 10 manual score in the frontmatter field importance. Judgement of how important the piece is to the author, with 10 being the most important.
The parenthetical “(rank R of T)” alongside the score is the page’s standing among all rated pages — lower numbers mean the piece is more important, so rank 1 is the most important and rank T the least. Ties share a single rank (the floored median of their positions), so two equally-rated pieces in a corpus of three both show “rank 1 of 3”.
tags
The tags frontmatter field, a list of strings. Shown as “Tags: x, y, z” with each tag linking to its own page; the “Tags” label links to the full Tags index.
audio
Optional. The audio frontmatter field, either a string URL or an object of the form {src, label}. Renders a small speaker icon in the metadata; click to expand the full audio player with playback-speed and 15-second skip controls.
