Spargebra ========= [![Latest Version](https://img.shields.io/crates/v/spargebra.svg)](https://crates.io/crates/spargebra) [![Released API docs](https://docs.rs/spargebra/badge.svg)](https://docs.rs/spargebra) [![Crates.io downloads](https://img.shields.io/crates/d/spargebra)](https://crates.io/crates/spargebra) [![actions status](https://github.com/oxigraph/oxigraph/workflows/build/badge.svg)](https://github.com/oxigraph/oxigraph/actions) [![Gitter](https://badges.gitter.im/oxigraph/community.svg)](https://gitter.im/oxigraph/community?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge) Spargebra is a [SPARQL](https://www.w3.org/TR/sparql11-overview/) parser. It supports both [SPARQL 1.1 Query](https://www.w3.org/TR/sparql11-query/) and [SPARQL 1.1 Update](https://www.w3.org/TR/sparql11-update/). The emitted tree is based on [SPARQL 1.1 Query Algebra](https://www.w3.org/TR/sparql11-query/#sparqlQuery) objects. The API entry point for SPARQL queries is the [`Query`] struct and the API entry point for SPARQL updates is the [`Update`] struct. Support for [SPARQL-star](https://w3c.github.io/rdf-star/cg-spec/#sparql-star) is also available behind the `rdf-star` feature. This crate is intended to be a building piece for SPARQL implementations in Rust like [Oxigraph](https://oxigraph.org). Usage example: ```rust use spargebra::Query; let query_str = "SELECT ?s ?p ?o WHERE { ?s ?p ?o . }"; let query = Query::parse(query_str, None).unwrap(); assert_eq!(query.to_string(), query_str); ``` ## License This project is licensed under either of * Apache License, Version 2.0, ([LICENSE-APACHE](../LICENSE-APACHE) or ``) * MIT license ([LICENSE-MIT](../LICENSE-MIT) or ``) at your option. ### Contribution Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in Oxigraph by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.
