Entity node in the knowledge graph

Fields

uuid: Uuid

Unique identifier

name: String

Entity name (e.g., “John”, “Paris”, “Rust programming”)

labels: Vec<EntityLabel>

Entity labels/types (e.g., [“Person”], [“Location”, “City”])

created_at: DateTime<Utc>

When this entity was first created in the graph

last_seen_at: DateTime<Utc>

When this entity was last observed

mention_count: usize

How many times this entity has been mentioned

summary: String

Summary of this entity’s context (built from surrounding edges)

attributes: HashMap<String, String>

Additional attributes based on entity type

name_embedding: Option<Vec<f32>>

Semantic embedding of the entity name (for similarity search)

salience: f32

Salience score (0.0 - 1.0): How important is this entity? Higher salience = larger gravitational well in the memory universe Factors: proper noun status, mention frequency, recency, user-defined importance

is_proper_noun: bool

Whether this is a proper noun (names, places, products) Proper nouns have higher base salience than common nouns
