Ontology IRI or Version IRI of ontology should be used for import?

For example, my ontology have 

ontology IRI: example.com/onto1

and 

current version IRI: example.com/onto1/1.0

What IRI should I use to import this ontology to new one?

I read the sections

  • 3.1 Ontology IRI and Version IRI

  • 3.3 Versioning of OWL 2 Ontologies

Of https://www.w3.org/TR/2009/REC-owl2-syntax-20091027 but have not yet grasped this issue.

And connected question: which URI should be specified as xmlns prefix in owl file in RDF/XML syntax?

Solution

  • The ontology IRI should be used to import an ontology when you do not care about the version - and you wish to use the latest version of an ontology. The version IRI will give you access to a specific version, if you, for example, need to refer to a particular state of the ontology (e.g., need to avoid the latest version because of undesired or erroneous inferences).
