[](https://github.com/oxigraph/rio/actions)
Warning: Rio is deprecated.
Please use instead [oxrdfio](https://docs.rs/oxrdfio)
or the more specific crates [oxttl](https://docs.rs/oxttl) and [oxrdfxml](https://docs.rs/oxrdfxml).
Rio is a low level library which provides conformant and fast parsers and formatters for RDF related file formats.
These libraries are going to be replaced by the [oxttl](https://crates.io/crates/oxttl) and [oxrdfxml](https://crates.io/crates/oxrdfxml) libraries.
It currently provides [N-Triples](https://docs.rs/rio_turtle/latest/rio_turtle/struct.NTriplesParser.html), [N-Quads](https://docs.rs/rio_turtle/latest/rio_turtle/struct.NQuadsParser.html), [Turtle](https://docs.rs/rio_turtle/latest/rio_turtle/struct.TurtleParser.html), [TriG](https://docs.rs/rio_turtle/latest/rio_turtle/struct.TrigParser.html) and [RDF/XML](https://docs.rs/rio_xml/latest/rio_xml/struct.RdfXmlParser.html) parsers and formatters.
It is split into multiple crates:
* `rio_api` provides common traits and data structures to be used in Rio parsers (`Triple`, `TriplesParser`, `Iri`...).
[](https://crates.io/crates/rio_api)
[](https://docs.rs/rio_api)
* `rio_turtle` provides conformant streaming parsers and formatters for [Turtle](https://www.w3.org/TR/turtle/), [TriG](https://www.w3.org/TR/trig/), [N-Triples](https://www.w3.org/TR/n-triples/) and [N-Quads](https://www.w3.org/TR/n-quads/).
[RDF-star](https://w3c.github.io/rdf-star/cg-spec/) syntaxes are also supported: [Turtle-star](https://w3c.github.io/rdf-star/cg-spec/#turtle-star), [TriG-star](https://w3c.github.io/rdf-star/cg-spec/#trig-star), [N-Triples-star](https://w3c.github.io/rdf-star/cg-spec/#n-triples-star) and [N-Quads-star](https://w3c.github.io/rdf-star/cg-spec/#n-quads-star).
[](https://crates.io/crates/rio_turtle)
[](https://docs.rs/rio_turtle)
* `rio_xml` provides a conformant streaming parser and a formatter for [RDF/XML](https://www.w3.org/TR/rdf-syntax-grammar/).
[](https://crates.io/crates/rio_xml)
[](https://docs.rs/rio_xml)
There is also the `rio_testsuite` crate that is used for testing Rio parsers against the [W3C RDF tests](http://w3c.github.io/rdf-tests/) to ensure their conformance.
It provides both an executable for building implementation reports and integration test to quickly ensure that the parsers stay conformant.
It is not designed to be used outside of Rio.
