.. _Export_ExportOntologyAsRDFSchemaFile: Export > Export Ontology as RDF Schema File ------------------------------------------- This feature, for Ontology asset collections, produces a downloadable file that contains the classes and properties that are declared in the ontology, but using the simplified RDF Schema vocabulary only. It will not include SHACL or OWL definitions. .. hint:: While the production version of your ontology for TopBraid should always be in SHACL, it sometimes makes sense to export a simplified RDFS version, especially for tools that do not handle SHACL. Here are some of the rules that will be executed during export: * Copies any triples associated with the current class, including ``rdf:type``, ``rdfs:subClassOf``, ``rdfs:comments`` and ``rdfs:labels``. Excludes blank nodes as those might be OWL axioms that would require deeper traversal and are not needed for RDFS export. * Copies any triples associated with the current ``owl:Ontology``. Excludes blank nodes in case those are used. * Creates an instance of ``rdf:Property`` for each URI path. Copies ``sh:name`` into ``rdfs:label`` and ``sh:description`` into ``rdfs:comment`` where applicable. * Assigns an ``rdfs:domain`` to a property if there is exactly one class that has the given property as its ``sh:property``. * Based on ``sh:datatype`` and ``sh:class`` constraints this sets the ``rdfs:range`` of the property, assuming that there is just a single constraint of this type anywhere. .. tip:: The exact SHACL rules that are used for the conversion can be found in the graph with URI ``http://datashapes.org/shacl2rdfs`` in the workspace. **See Also** * :ref:`Export_ExportOntologyAsOWLFile` **Further Reading on SHACL** * `Form Generation using SHACL and DASH (External Link) `_ * `SHACL Advanced Features Specification (External Link) `_ * `SHACL W3C Specification (External Link) `_ **Further Reading on Ontologies** * :ref:`working_with_ontologies_target` **Further Reading on TopBraid** * :ref:`introduction`
