owl2yarrrml 1.2

A Python library for translating OWL ontologies into YARRRML mappings

Transforming your ontology into YARRRML mappings

This script generates a YARRRML template from the input ontology. The transformations made are:

Ontology	Mapping
Class	TriplesMap + Simple PredicateObjectMap (rdf:type, class)
Data Property	Simple PredicateObjectMap in the TriplesMap corresponding to the class defined in the domain of the property
Object Property	Join PredicateObjectMap in the TriplesMap corresponding to the class defined in the domain of the property and where the parentTriplesMap is the TriplesMap corresponding to the class defined in the range of the property

How to execute it

Execution from CLI

The input ontology can be serialized in NTRIPLES, RDF/XML or Turtle

python3 -m pip install owl2yarrrml
python3 -m owl2yarrrml -i paht/ontology.xml -o ouput_path/mapping.yml

Execution as a library

The ontology has to be provided in RDF/XML.

import owl2yarrrml
import owlready2
ontology=owlready2.get_ontology("file://path/to/my/ontology.xml").load()
yarrrml_content = owl2yarrrml.translate(ontology)
