Subject: [ExternalEmail] ISSUE-144 - OWL-Time - missing interval relations

I implemented
:intervalDisjoint (Allen & Ferguson 1997)
:intervalIn (Allen 1984)
Given OWL2 lack of expressiveness around union-of-properties, I did it by making

            :intervalAfter, :intervalBefore each sub-properties of :intervalDisjoint
            :intervalStarts, :intervalFinishes, :intervalDuring each sub-properties of :intervalIn

And added documentation to the text to match.

While I was at it I made reverse inverseOf relations and domain and range of all :interval* properties explicit, so we are not relying solely on OWL entailments.

Implemented in the branch https://github.com/w3c/sdw/tree/simon-time-interval-relations
