Import & Export RDF Ontologies
Import an RDF/Turtle ontology as a new named ontology, and export an existing ontology back to Turtle.
Import & Export RDF Ontologies
Analytics → Ontology can import an RDF/Turtle (OWL/RDFS) ontology and export an existing ontology back to Turtle.
Import
- Open Analytics → Ontology and click Import RDF.
- Give the ontology a name — each import becomes its own ontology, so the name becomes the ontology's identifier. Re-importing with the same name adds any newly declared types to that ontology (it does not remove types that are no longer present).
- Paste RDF/Turtle or upload a
.ttl/.rdf/.owlfile. - Click Validate to preview what will be created — object types, link types, properties, and any warnings.
- Click Import Ontology. The new ontology opens in the Designer.
What gets imported
| RDF construct | Becomes |
|---|---|
owl:Class / rdfs:Class | Object type (kind: transactional) |
owl:DatatypeProperty (with rdfs:domain) | A property on that object type; rdfs:range maps to a scalar type |
owl:ObjectProperty (with rdfs:domain/rdfs:range) | Link type between the two object types |
Individuals (instance data) — e.g. ex:Alice a ex:Person — are not
imported. Only the schema (classes and properties) is created. The validation
preview reports how many individuals were ignored.
If a property's domain or a relationship's domain/range does not resolve to a declared class, that item is skipped and listed as a warning.
Export
On the Ontology page, click Export RDF to download the currently selected
ontology as a .ttl Turtle file. Object types export as owl:Class,
properties as owl:DatatypeProperty, and link types as owl:ObjectProperty.
