ontologos 0.3.0

Python bindings for the OntoLogos OWL reasoner (pre-release)

ontologos (PyPI)

Python bindings for OntoLogos — a modular Rust ontology reasoner for OWL EL, RL, and RDFS.

This is an alpha placeholder (v0.3.0). The package installs and reports its version. Reasoner(path) loads OWL files via the Rust parser. Pass profile="rdfs" to run RDFS materialization via classify(); the default profile returns not-implemented until OWL EL/RL classification ships in v0.5.

Capability	Rust v0.3	Python
In-memory ontology model	Yes (ontologos-core)	No
OWL file loading	Yes (ontologos-parser)	Partial (Reasoner(path) loads only)
Profile detection	Yes (ontologos-profile)	No
RDFS materialization	Yes (ontologos-rdfs)	Partial (Reasoner(path, profile="rdfs"))
OWL classification	No (v0.5)	No
Full Python API	—	v0.9 / 1.0

For working Rust APIs today, use crates.io crates (ontologos-core, ontologos-parser, ontologos-profile, ontologos-rdfs).

pip install ontologos

import ontologos

print(ontologos.__version__)

reasoner = ontologos.Reasoner("ontology.owl", profile="rdfs")
reasoner.classify()
