OxRDF is a simple library providing datastructures encoding [RDF 1.1 concepts](https://www.w3.org/TR/rdf11-concepts/).
This crate is intended to be a basic building block of other crates like [Oxigraph](https://crates.io/crates/oxigraph) or [Spargebra](https://crates.io/crates/spargebra).
Support for [RDF-star](https://w3c.github.io/rdf-star/cg-spec/2021-12-17.html) is available behind the `rdf-star` feature.
OxRDF is inspired by [RDF/JS](https://rdf.js.org/data-model-spec/) and [Apache Commons RDF](http://commons.apache.org/proper/commons-rdf/).
Usage example:
```rust
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);
```
