Before you integrate¶
Read this once before loading ontologies or calling classify() in production.
Partial OWL mapping¶
The parser maps a subset of OWL constructs into the core model. Complex class expressions, many data-property axioms, and some property axiom shapes are scanned for profile detection but skipped during mapping.
ontology.axiom_count()is mapper output, not Protégé's logical axiom total.- Family.owl: ~57 mapped axioms is normal.
- Skipped items appear in
parse_meta.skipped_axiom_countandparse_meta.warnings.
See Protégé axiom counts · Supported constructs.
owl:imports¶
| Format | Local imports merged? | Remote URLs fetched? |
|---|---|---|
| RDF/XML | Yes (default) | Never |
| Turtle, OWL Functional | No | Never |
Merge multi-file bundles with ROBOT before loading when imports are remote or cross-format.
See OWL imports reference · Known limitations.
Rust API footgun¶
Use ontologos_parser::load_ontology and ontologos_facade::classify(&mut reasoner) — not Ontology::from_file or reasoner.classify() on core.
See Rust integration contract.
OWL DL scope¶
HermiT parity metrics apply to 889 gated conformance cases, not every real-world ontology. Validate DL results on your corpus before production.
See Evaluator scope · When not to use OntoLogos.
Release channel¶
Published today: v1.1.4 on crates.io and PyPI. Pin install commands to Release status.
