purrdf

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.

Federates Sentinel-2 COGs (raster) and Overture Maps GeoParquet (vector) via DuckDB FDW, PostGIS, and PL/Python. Evaluates two raster integration strategies, and SPARQL (Ontop VKG) vs REST API (pg_featureserv) trade-offs. Fully Dockerised.
