Example: 

?x t:intervalCotemporal ?y

Matches interval ?x and interval ?y such that ?x and ?y are equivalent.

?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., Intervals ?x and ?y both start at the same time and end at the same time or intervals ?x and ?y both start at the same point and end at the same point.

Notes

The following namespace abbreviations are used:
