# Types

Types describe what kind of thing a note represents: Project, Person, Topic, Procedure, Event, or any category you create.

## Type Field

The `type:` field assigns a note to a type.

```yaml
type: Project
```

Tolaria does not infer type from folder location. Moving a file into another folder does not change its type.

## Prefer Types Over Folders

Types are the preferred way to group notes in Tolaria. Folders are supported for existing vaults and fallback organization, but Tolaria is built around types and relationships because they carry stronger meaning than file paths.

Use types for semantic groups such as Projects, People, Topics, Procedures, Events, and Essays. Use relationships to connect notes across those groups. This gives Tolaria better structure for navigation, filtering, properties, templates, and future automation than folder location alone.

## Type Documents

Type documents are Markdown notes with `type: Type` in frontmatter. They describe how a type should appear and what new notes of that type should start with.

```yaml
---
type: Type
_icon: folder
_color: blue
_sidebar_label: Projects
_order: 10
---

# Project
```

## What Types Control

- Sidebar grouping.
- Type icon and color.
- Sidebar order and label.
- Pinned properties.
- New-note templates.

## New Note Defaults

Type documents can define empty properties and relationships. When you create a new note of that type, Tolaria shows placeholders for those fields so you can fill them in from the Properties panel.

If a type document gives a property a value, that value becomes the default for new notes of that type. For example, a Project type can define `status: Active` so every new project starts active until you change it.
