Blackcat Informatics Inc. ORG

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).

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.

PurRDF — one RDF 1.2 engine, one behavior, every language: interned primitives, Turtle/TriG/N-Quads/RDF-XML/JSON-LD codecs, RDFC-1.0, SPARQL 1.1/1.2, SHACL Core, GTS graph transport, and Python/WebAssembly/C bindings.
