temporal-database

An embedded evidence database for facts that disagree—preserving source, time, certainty, and history.

A Python library that adds time-travel queries to your PostgreSQL database. Query any entity at any point in history.

Temporal Knowledge Graph System for Architectural Memory - Track decisions, patterns, and failures with MCP integration for Claude Code/Desktop

Production-grade time-versioned key-value store with snapshots, LRU caching, TTL, and async support

ReMemNetDB is an LLM-powered temporal knowledge graph database that tracks how entities and relationships evolve over time. Combining semantic search with time-aware queries, it helps build AI systems that remember context and changes—not just facts—making data more meaningful and actionable.

Reference implementation of the Observability Watermark Specification (OWS)

A fact graph in a single SQLite file — embedded temporal fact store with time travel, provenance, hybrid search, and MCP for AI agents

Durable, explainable memory infrastructure for AI systems

Bitemporal memory for AI agents: deterministic contradiction resolution, provenance, and retrieval at any point in time.

A data structure that maps whatever world it's shown — real or fiction. The memory under the holodeck.

A modular C++ append-only temporal database built from scratch featuring a custom binary storage engine, schema serialization, immutable versioned records, crash recovery, temporal indexing, snapshots, rollback, time-travel queries, and a SQL-like query engine. Future work includes secondary indexes, log compaction, and semantic vector search.

Python SDK for Relata DB — sovereign intelligence database by ZySec.AI

AttemptDB - the database for what AI coding agents tried. Local-first, temporal and causal, written in Rust.

An embedded bitemporal graph ledger — concepts, typed relationships, and their full history of change, with hybrid vector/keyword search, graph traversal, and in-memory analytics, in a single .db file.

Persistent multi-KB daemon for agents — bitemporal facts, Datalog rules, provenance, branches. Built on rayforce2.

TypeScript SDK for Relata DB — sovereign intelligence database by ZySec.AI

Time-aware Merkle trees for blockchain, audit trails, and secure data verification

Eva — Geo-Temporal Context Core for LLM Agents

Append-only, bitemporal, audit-native analytical database engine — time-travel, provenance, and auditability as first-class. Rust, Postgres-wire compatible.

Temporal generative art with immutable time-travel. Distroless security, zero-cost deployment. A Clojure/ClojureScript sovereignty demonstration.
