ufo-rdf 1.0.0-alpha.0

High-performance RDF parsing for Chez Scheme

A fast, single-pass RDF 1.1 parser for Chez Scheme (R6RS). Terms are

plain immutable values (IRIs are interned strings, no eager RFC 3986

parsing); the N-Triples parser scans UTF-8 bytes with a 256-entry

character-class table and emits triples directly, with no intermediate

representation. Passes the W3C N-Triples test suite (70/70).
