rustdl-py
Python wrapper for rustdl — a Rust-native OWL 2 DL reasoner.
Zero Java. Zero C bindings. Just cargo install owl-dl-cli + pip install rustdl-py.
Install
# 1. Install the reasoner
cargo install owl-dl-cli
# 2. Install the Python wrapper
pip install rustdl-py
Quick Start
import rustdl_py
# Check consistency
consistent = rustdl_py.is_consistent("my_ontology.ofn")
# Classify (compute class hierarchy)
result = rustdl_py.classify("my_ontology.ofn")
print(f"Classes: {result.classes}, Mode: {result.mode}")
for subclass, superclass in result.subsumptions:
print(f" {subclass} ⊑ {superclass}")
# Realize (compute individual types)
r = rustdl_py.realize("my_ontology.ofn")
for individual, types in r.types.items():
print(f"{individual}: {', '.join(types)}")
# Explain a subsumption
explanation = rustdl_py.explain("my_ontology.ofn", ":Foo", ":Bar")
print(explanation["detail"])
API
| Function | Description |
