Properties reference
Properties are YAML frontmatter at the very start of a note.
| Property type | Example |
|---|---|
| Text | title: My title |
| Number | rating: 4.5 |
| Checkbox | completed: true |
| Date | date: 2026-07-21 |
| Date and time | due: 2026-07-21T14:30:00 |
| List | tags: [one, two] or a YAML list |
| Link | related: “Other Note” |
Obsidian reserves tags, aliases, and
cssclasses for their built-in behaviors. Tags may contain letters,
numbers (not as the first character), underscores, hyphens, and forward slashes.
Prefer YAML lists when a property naturally has multiple values.
