Entity Centric Knowledge Graph Construction With Temporal Versioning

Knowledge Engine for AI Agent Memory in 6 lines of code

Unique: Stores temporal metadata (timestamps, version numbers) as native graph properties rather than in a separate temporal database, enabling temporal queries to leverage the same graph traversal engine as structural queries. Supports both point-in-time snapshots and range-based temporal queries, allowing agents to reason about knowledge at different temporal granularities.

vs others: More integrated than external temporal databases because temporal queries use the same graph engine as structural queries, reducing latency and complexity; more flexible than immutable event logs because it preserves the full graph structure at each point in time, enabling complex temporal reasoning.
