Ontology

Publishes site structure as OWL ontology. Enable module and open /owl page.

It publishes entity type and bundles as OWL classes, RDF mapped fields as OWL object properties.

Drupal RDF-mappings are exported as OWL class subClassOf for entity types and OWL property equivalentProperties for fields.

Drupal 8 version ties commerce product variation entity bundles to schema.org/Offer and commerce price to schema.org/price.

Example output:

  <!-- Classes for commerce_product_variation entities -->
  <Class xmlns="http://www.w3.org/2002/07/owl#" rdf:about="#commerce_product_variation"/>
  <Class xmlns="http://www.w3.org/2002/07/owl#" rdf:about="#commerce_product_variation--default">
    <rdfs:label>Default</rdfs:label>
    <rdfs:subClassOf rdf:resource="#commerce_product_variation"/>
    <rdfs:subClassOf rdf:resource="schema:Offer"/>
  </Class>
  <!-- Property for field price-->
  <ObjectProperty xmlns="http://www.w3.org/2002/07/owl#" rdf:about="#price">
    <equivalentProperty rdf:resource="&schema;price"/>
    <rdfs:domain rdf:resource="#commerce_product_variation--default"/>
    <rdfs:range rdf:resource="&xsd;string"/>
  </ObjectProperty>
