/def/irg
This ontology is a specialisation of the Registry Ontology (REG) used to manage Internationalized Resource Identifiers (IRIs). "IRI" is a generalised and more modern name for URIs - Uniform Resource Identifiers.
The major specialisation in this ontology is the subclassing of reg:RegisterItem to irg:RegisteredIRI which just mandates the use of a few extra properties for IRI management.
Another difference between this ontology and REG is not IRI-specific but a general development: here we define the statuses of reg:RegisterItem instances to be held within temporal objects, irg:StatusPeriod instances, sub classes of OWL TIME's time:ProperInterval allowing us to stack up multiple, time-bounded, statuses per irg:RegisteredIRI.
