How to save an Ontology?
The Export dialog allows you to save an ontology into a different file (and possibly in a different format).
To export an ontology, proceed as follows:
- Select an ontology.
- Export an ontology.
Right-click the ontology and select Export.
The Export wizard opens. Choose the "OWL2 Ontology to Filesystem" option in the Ontologies section.
- Specify the ontology to be exported.
Enter the following information:
- Select Project. Select the project from which you want to export the ontology.
- Select Ontology. Select the ontology you want to export.
- To File. Select a file name and file type of the ontology to be exported.
It is best to use the "Browse" button to open the file chooser.
In the file chooser a variety of file types are available:
- OWL/RDF – The official OWL2 W3C recommendation in RDF/XML.
- OWLX – An OWL2-XML presentation of the official OWL 2 W3C recommendation.
- OWL2 – The functional syntax of the official OWL 2 W3C recommendation.
- OMN – The Manchester syntax for OWL 2.
- TTL – A Turtle serialisation format for the RDF graph of the OWL 2 ontology.

- Click Finish.
The ontology will be exported. To discard your changes, click Cancel.
