Re: Questions about Time Ontology

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!

Feng
