Expand description

Implements data structures for RDF 1.1 Concepts using OxRDF.

Usage example:

use oxigraph::model::*;

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);
