Overview

The IRI structure of the IOF references the OWL documents providing a versioned and not-versioned form. The latter form will always refer to the latest released version of the documents. For the IRI syntax, please refer to RFC 3987 from The Internet Engineering Task Force (IETF).

...

All IOF IRIs MUST be resolvable and refer to a resource that can be retrieved from the internet. The form of the IRI MUST specify the protocol as HTTPS and the authority MUST be a domain administered and owned by the IOF or its parent organization. The IOF MUST choose a single authority for all ontologies released by the IOF. The authority www.industrialontologies.org is used for illustrative purposes only. When decided, this document MUST be revised with the normative authority.

The authority MUST be a domain administered and owned by the IOF or its parent organization. The IOF MUST choose a single authority for all ontologies released by the IOF. The authority MUST be www.industrialontologies.org unless it is not possible due to technical reasons. Otherwise, the authority may begin with an alternative such as www.industrialontologies.org or onto.industrialontologies.org.
