Adds a naive standalone query optimizer This drops some left join optimizations
2 years ago
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).
