Add an owl:versionIRI to the ontology metadata

[florenceclavaud]

This would make RiC-O compliant with the OWL 2 specification as concerns ontology documents.

To be more precise, we have several versions of RiC-O, having the same IRI, which is correct. Only the latest version of RiC-O is accessible through its IRI, which is also correct. But the current version should also be made compliant with the following rule:
"An ontology series is identified using an ontology IRI, and each version in the series is assigned a different version IRI. The ontology document of the ontology representing the current version of the series SHOULD be accessible via the ontology IRI and, if present, via its version IRI as well; the ontology documents of the previous versions SHOULD be accessible solely via their respective version IRIs. When a new version O in the ontology series is created, the ontology document of O SHOULD replace the one accessible via the ontology IRI (and it SHOULD also be accessible via its version IRI)." (from section 3.3 of the OWL 2 Web Ontology Language Structural Specification and Functional-Style Syntax).

Of course it is easy to add an owl:versionIRI to the ontology file. However, as concerns using the version IRI to access the ontology, we have to contact the company that hosts the ICA website and ask them to change the configuration accordingly.

So, I have added the following line to the ontology metadata of RiC-O 1.0.2 file (in the next-version branch):
<owl:versionIRI rdf:resource="https://www.ica.org/standards/RiC/ontology/1.0.2"/>

Now RiC-O 1.0.2 is in the master branch. I am closing the issue.
