What ships in v0.1.0

Only the ontologos-core crate is published to crates.io. It provides:

• In-memory ontology data model (interned IRIs, entity registry, structured axioms)
• OntologyBuilder for programmatic construction
• JSON snapshot v2 (to_json / from_json) with deserialization limits
• Axiom indexes for downstream reasoning engines

OWL file parsing, profile detection, and reasoning engines are planned for v0.2+.

Breaking changes

• JSON snapshot format is v2 only for untrusted input (v1 rejected)
• AxiomKind replaced by structured Axiom with entity references

Quick start

cargo run -p ontologos-core --example pizza_builder
