rdf-star

Powerful RDF Knowledge Graph Generation with RML Mappings

Rust-native, modular platform for Semantic Web, SPARQL 1.2, GraphQL, and AI-augmented reasoning

PurRDF — one RDF 1.2 engine, one behavior, in Rust, Python, WebAssembly and C. Deterministic BM25 full-text search, exact GeoSPARQL 1.1 and embedding kNN answered from SPARQL, in-process, over one dataset: the three jobs a triple store usually kept PostgreSQL beside it for. Plus native codecs, RDFC-1.0, SHACL, ShEx, entailment and GTS transport.

RML-star: RDF-star generation for RML

Ground LLM output as provenance-tracked claims, not truths. A maximal super-ontology + native RDF-1.2 logic: reasoning engine — OWL, SHACL, SSSOM, EDOAL are generated lossy projections; a correspondence calculus losslessly subsumes external vocabularies. Rust-first (pip / MCP / GTS).

Use cases for generating RDF-star from heterogeneous data sources

An image is not a sentence: a VLM's description of one is unvalidated prose. VSON makes every claim about an image — object, property, spatial relation, action — a graph assertion SHACL can reject, so a build can fail on it. Rust CLI, Python API, MCP server, keyless browser studio. It checks the graph, not the picture.

A single-file, content-addressed, append-only transport for RDF 1.2 graphs — four interoperable engines (Rust, Python, Go, TypeScript), one spec, one conformance corpus.
