]> Mapping OWL Time ontology to IOF Core ontology This ontology maps some concepts of the OWL Time (https://www.w3.org/TR/owl-time/) to corresponding concepts of IOF Core to enable IOF Core to associate calendar date and clock time to a Time Instant as well as a measurement of duration to a Time Interval based on various reference systems, e.g., calendar and clock systems) and units, e.g., hour, minute, second.
