| Description | A temporal RDF graph database written in Rust. Each transaction is an immutable, content-addressed commit, so data can be queried as of any point in history, with git-style branching, triple-level access policies, and built-in full-text, vector, and geospatial search. | A Virtual Knowledge Graph system that exposes relational databases as RDF knowledge graphs, translating SPARQL queries into SQL without moving data. Uses R2RML mappings and lightweight ontologies. |
