Propose your ontology to the ONKI service.

Practical issues

We recommend that you present your ontology using the SKOS format, which allows the instant publication of the ontology. Also all RDF formats are accepted, but require additional configuration work from ONKI administrators.

You can either upload the file using the form or give us the web address (URL) which from the file can be fetched. If the file is big (over tens of megabytes), we recommend using the URL method. To restrict the size of the file, we recommend using zip compression.

We are thankful for all inquiries, suggestions and feedback! You can give feedback via email or by contacting the ONKI team by using other methods.


By uploading the ontology, you accept the following terms.
