sparopt is a work in progress [SPARQL Query](https://www.w3.org/TR/sparql11-query/) optimizer.
|
|
|
|
It relies on the output of [spargebra](https://crates.io/crates/spargebra).
|
|
|
|
Support for [SPARQL-star](https://w3c.github.io/rdf-star/cg-spec/2021-12-17.html#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).
