A record of an entity that has been persisted in the datastore, with its associated metadata.

An [Entity] represents a real-world object, concept, or thing within the knowledge graph. It contains structured data in the form of properties, optional link data for establishing relationships with other entities, and comprehensive metadata that describes the entity's provenance, types, temporal information, and more.

Each entity is an instance of one or more EntityTypes defined in the ontology. The relationship is similar to objects and classes in object-oriented programming:

• EntityTypes define the schema, structure, and constraints that entities must follow
• [Entity] instances contain actual data conforming to those schemas

An entity:

• Is identified by a unique [EntityId]
• Has one or more VersionedUrls in its entity_type_ids field linking to its types
• Contains a set of properties structured according to the schemas defined in its types
• May have links to other entities, establishing relationships in the knowledge graph
• Includes comprehensive metadata for tracking provenance, versioning, and confidence
