An open-source enterprise world model claiming a world-first, records not just "current" knowledge but the timeline of when something was true and when the system started believing it. Title: deeplethe/utopia URL: 📝 Overview Built in Rust on PostgreSQL + pgvector, Utopia centers on a bitemporal knowledge graph as the core of an enterprise knowledge-governance platform. ❗ Problem it solves Existing vector stores and knowledge graphs focus only on keeping "the present" correct, leaving decision traceability and audit trails largely missing. ⚙️ Methodology Every fact carries two timestamps — when it was true in the world, and when the system came to believe it — combined with conflict detection, entity resolution, and ontology-driven inference. Every operation is recorded in a tamper-evident decision ledger. 🔧 Use cases It ingests sources ranging from PDFs to Notion, Jira, and S3, connects to Claude Desktop and Cursor via MCP, and supports fully offline deployment in air-gapped environments — a good fit for compliance-heavy settings. 📊 Results It's already earned 9,000+ GitHub stars and 1,000+ forks, spins up easily with Docker Compose, and remains under active development at v0.1. #OpenSource# #KnowledgeGraph#
