# Metadata Standards
Use lowercase property names for new notes. Add only the fields that help identify, filter, or retrieve the note.
## Core Properties
| Property | Purpose | Typical values |
| --- | --- | --- |
| `type` | What the note is | `hub`, `reference`, `checklist`, `incident`, `change` |
| `status` | Current lifecycle state | `draft`, `active`, `planned`, `in-progress`, `complete`, `archived` |
| `date` | Date of the event or record | `YYYY-MM-DD` |
| `tags` | Broad discovery terms | lowercase, reusable terms |
| `publish` | Intended publication state | `true` or `false` |
## Operational Records
Home & Property records may also use `id`, `domain`, `cost`, `vendor`, `warrantyUntil`, `related`, and `resolvedBy`.
Home Lab records may also use `id`, `system`, `service`, `impact`, and `related`.
## Privacy Rules
- Notes under `10 Personal` and `_Inbox` are private and use `publish: false`.
- Personal templates under `02.08 Personal Templates` are private.
- Non-personal notes can use `publish: true` after their content is reviewed.
- Folder exclusions in Obsidian Publish are the enforcement boundary; the `publish` property is a review aid.
- Never publish credentials, access tokens, private addresses, health information, support ticket identifiers, or DM-only campaign material.
