ontologos-core = "0.9.0"
ontologos-parser = "0.9.0"

Bump all ontologos-* pins together. On main, use "1.0.0" for DL and the full engine set.
Quick start
Download family.owl first:
curl -L -o family.owl \
https://raw.githubusercontent.com/eddiethedean/ontologos/main/benchmarks/data/family.owl
use ontologos_core::{Profile, Reasoner};
use ontologos_facade::ClassifyOutcome;
use ontologos_parser::load_ontology;
let ontology = load_ontology("family.owl".as_ref())?;
let mut reasoner = Reasoner::builder()
.profile(Profile::Auto)
.build(ontology)?;
match ontologos_facade::classify(&mut reasoner)? {
ClassifyOutcome::Taxonomy(t) => println!("{}", t.subsumption_count()),
ClassifyOutcome::Rdfs(r) => println!("{}", r.inferred_total()),
ClassifyOutcome::Rl(r) => println!("{}", r.inferred_total()),
}
