Frontmatter Fields

Tolaria uses conventions instead of a required schema.

Field	Meaning
type	The note's entity type.
status	Lifecycle state.
icon	Per-note icon.
url	External URL.
date	Single date.
belongs_to	Parent relationship.
related_to	Lateral relationship.
has	Contained relationship.
_width	Per-note editor width override.
_display	Display mode. Omit for text notes; use sheet for spreadsheet notes.
_icon, _color	Type or note appearance metadata.
_sidebar_label, _order	Type sidebar label and order.
_pinned_properties	Properties pinned for a type.
_sheet	Sheet-note presentation metadata such as grid settings, column widths, row heights, and cell formatting.

Custom Fields

You can add your own fields. If a field contains wikilinks, Tolaria can treat it as a relationship.

System Fields

Fields starting with _ are reserved for system behavior and hidden from standard property editing. They remain plain YAML, so they can still be inspected or changed in raw mode when needed.

Nested keys under a system field are also system-owned. For example, _sheet.cells.B6.num_fmt belongs to the sheet editor and should not appear as a normal user property.
