A memory node: the atomic unit of knowledge in MenteDB.

Combines vector embeddings, graph connections, temporal properties, and flexible attributes in a single primitive.

Fields

id: MemoryId

Unique identifier.

agent_id: AgentId

The agent that owns this memory.

memory_type: MemoryType

Memory type classification.

embedding: Embedding

Embedding vector for semantic similarity search.

content: String

Human-readable content.

created_at: Timestamp

When this memory was created.

accessed_at: Timestamp

When this memory was last accessed.

access_count: u32

How many times this memory has been accessed.

salience: Salience

Current salience score (decays over time).

confidence: Confidence

Confidence in this memory’s accuracy.

space_id: SpaceId

The memory space this belongs to.

attributes: HashMap<String, AttributeValue>

Flexible key-value attributes.

tags: Vec<String>

Tags for bitmap indexing.
