    pub name: String,

    pub deleted_at: Option<Timestamp>,
}

A graph node with a type, display name, and key-value properties.

Fields

header: Header

Identity and namespace metadata shared by all substrate records.

kind: EntityKind

Closed base kind that classifies this entity.

entity_type: Option<String>

Pack-governed subtype token (e.g. "paper", "snapshot"). Never stored raw in properties — queries compile this to entities.entity_type = ?.

name: String

Human-readable display name (required; must be non-empty).

description: Option<String>

Optional long-form description of this entity.

properties: BTreeMap<String, PropertyValue>

Arbitrary structured metadata as key-value pairs.

tags: Vec<String>

Categorical labels for filtering and retrieval.

deleted_at: Option<Timestamp>

Set when the entity is soft-deleted; absent means active.
