Example: 

  ?x t:intervalBefore ?y

Matches interval ?x and interval ?y such that endpoint of ?x is before the startpoint of ?y on the timeline.

?x and ?y can be defined as intervals using either times or points (though they must both be defined using the same mechanism).

I.e., Either ?x has t:endtime ?endTime and ?y has t:starttime ?startTime and ?endTime is before ?startTime on the timeline or ?x has t:endpoint ?endPoint and ?y has t:startpoint ?startPoint and ?endPoint is before ?startPoint .
