OxRDF

OxRDF is a simple library providing datastructures encoding RDF 1.1 concepts.

This crate is intended to be a basic building block of other crates like Oxigraph or Spargebra.

Support for RDF-star is available behind the rdf-star feature.

OxRDF is inspired by RDF/JS and Apache Commons RDF.

Use oxrdfio if you need to read or write RDF files.

Usage example:

use oxrdf::*;

let mut graph = Graph::default();

// insertion
let ex = NamedNodeRef::new("http://example.com").unwrap();
let triple = TripleRef::new(ex, ex, ex);
graph.insert(triple);

// simple filter
let results: Vec<_> = graph.triples_for_subject(ex).collect();
assert_eq!(vec![triple], results);
