Titanium RDF N-QUADS

A Java implementation of a streaming RDF N-Quads reader and writer, optimized for efficient parsing, serialization, and handling of large RDF datasets. It enables scalable processing of RDF statements in a memory-efficient, streaming fashion.

Formerly part of Titanium JSON-LD

Example

// Reading N-Quads
new NQuadsReader(reader).provide(RdfQuadConsumer);

// Writing N-Quads
new NQuadsWriter(writer).quad(...).quad(...).quad(...);

// Demonstrating RdfQuadConsumer usage by reading and writing in one step
// Since NQuadsWriter implements the RdfQuadConsumer interface,
// it can be directly used as a consumer, e.g. with JsonLd.toRdf.
new NQuadsReader(reader).provide(new NQuadsWriter(writer));

// Static access to NQuadsWriter methods
var encoded = NQuadsWriter.nquad(...);
var encodedLiteral = NQuadsWriter.literal(...);
