utopia: Enterprise Knowledge Graph That Records the Passage of Time
deeplethe/utopia
About the project
This is a bitemporal graph-based platform that tracks the evolution of knowledge, rather than serving as a simple storage repository. Unlike existing vector stores that retain only the current state, it records both the validity period of facts and the time the system recognized them, clearly preserving the rationale for decision-making.

It automatically synchronizes with diverse sources, from PDF and Office documents to GitHub, Jira, and S3, extracting entities and detecting conflicts based on ontologies. Built with a single Rust binary and Postgres, it offers lightweight deployment and includes built-in search and RAG capabilities combining Tantivy and pgvector.
It can directly integrate with agents such as Claude Desktop and Cursor via an MCP server. By applying Ontology2SQL technology, users can query connected databases in natural language, and all change histories are recorded in an immutable decision ledger for audit trails.
