Properties
Properties are structured metadata stored in Markdown frontmatter. They make notes easier to filter, sort, script, or share with tools that understand YAML metadata.
Basic frontmatter
Frontmatter appears at the top of a Markdown file between --- markers.

The rest of the note remains ordinary Markdown.
When to use properties
Use properties for stable, structured facts:
- Status.
- Project.
- Owner.
- Date.
- Source.
- Review state.
- Related IDs from another system.
Use normal prose for meaning, reasoning, and nuance.
Properties panel
The properties panel gives a contextual view of metadata for the active note. It is useful when you are reviewing many notes with the same schema.
Practical schema
Start small:
status: draft
type: note
project:
reviewed:
Add fields only when you know how you will search, sort, or maintain them.
