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).
...
In accordance with IETF RFC 3987, the Path component of the IRI MUST immediately follow the authority starting with a forward-slash (/
), and the Path Parts parts MUST be separated by forward-slashes (/
). The first Part part of the Path is referred to as the Root.
IRI Path Root
The root of the path portion of the IRI IRI Path Root Part MUST be /ontology
. This provides the ability to have documentation and other supporting resources referenced in alternate root directories, such as /documentation
or /references
. The IOF MUST designate each root resource name for a specified use.
