description	YAML frontmatter rules for Moss note metadata. Use when adding or editing the optional metadata block at the top of a note.

Frontmatter

Frontmatter is an optional YAML block at the top of the note:

---
status: active
tags:
  - project
people:
  - jane
---

# Note Title

• Put structured metadata in frontmatter, not in the body.
• Use a top-level YAML mapping. Prefer simple values and string lists; nested objects are read-only in Moss.
• Use type, people, description, tags, and status only when they help retrieval. For workspace notes, let Moss manage created_date.
• The note title comes from the leading # H1, not a frontmatter title: key.
• Omit the block when no metadata is needed.
• Do not duplicate frontmatter values as prose headings or bold labels.

Editing Frontmatter

Keep YAML valid. Moss preserves malformed frontmatter but cannot edit it. When editing files, edit metadata inside the frontmatter block; in the app, use the Properties tab.
