py_mmut_rdf 0.0.3

Python library providing RDF ontology definitions for SysML.

py-mmut-rdf

A Python library providing RDF ontology definitions for MMUT (MicroModel and Transformations). This library contains a generated TTL (Turtle) file with MMUT ontology definitions and provides a convenient Python interface to access the ontology classes and properties.

Ontology Visualization

Visualized the ontology with WebVOWL

Installation

See: https://pypi.org/project/py_mmut_rdf/

pip install py-mmut-rdf

Usage

from py_mmut_rdf import MMUT
from rdflib import URIRef, Graph, RDF

g = Graph()
g.bind("mmut", MMUT._NS)
g.add((URIRef("http://example.org#model_x"), RDF.type, MMUT.RDFMicroModel))

SHACL Validation in Python

from importlib.resources import files
from pyshacl import validate
from rdflib import Graph

data_graph = Graph()
# data_graph.parse("path/to/your-model.ttl", format="turtle")

shapes_path = files("py_mmut_rdf").joinpath("mmut-shapes.ttl")
conforms, report_graph, report_text = validate(
	data_graph=data_graph,
	shacl_graph=str(shapes_path),
)

print(conforms)
print(report_text)

SHACL Validation

The library includes SHACL shapes in py_mmut_rdf/mmut-shapes.ttl.

Install pySHACL if needed:

pip install pyshacl

1. Loop Example (should fail)

pyshacl -s py_mmut_rdf/mmut-shapes.ttl path/to/test-loop.ttl -f human

Expected result: Conforms: False

2. Real MMUT Example

pyshacl -s py_mmut_rdf/mmut-shapes.ttl path/to/mmut-squirrl.ttl -f human

Tip: add -d for verbose diagnostics.

Development

Regenerating the Ontology

If you need to recreate the TTL file:

python create_mmut_ontology.py

Testing

Run the test script to verify everything works:

python -m pytest tests/

Building the Package

poetry build

Publish the Package

poetry publish --username __token__ --password <TOKEN>

Versioning via Git Tags

The package version is derived automatically from Git tags during build/release.

Use semantic version tags, e.g.:

git tag v0.0.3
git push origin v0.0.3

In GitHub Actions, the workflow fetches tags and builds the package with the tag-derived version.
