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);
|
|
```
