Dear Wiebke Wagner, Thank you for your interest in the OWL-Time ontology. > 1. Why has the property "inside" the domain of the class "interval" und the range of the class "instant". Shouldn't it be the other way around in the sence that an instant is inside an interval and not an interval is inside an instant? Please see our answer to this question in our previous posts to the list [1,2]. > 2. Why has the Property "hasDurationDescription" a domain of "TemporalEntity" and not a domain of "Interval", because the Duration of an "Instant" is alway zero, so why giving it this property via inheritance? Either way is OK, and we decided to go for "TemporalEntity", and zero is also a valid value for durations. Thanks!
