An ontology that extends the W3C "time" ontology (https://www.w3.org/2006/time) to integrate time intervals and time points.

Also see https://www.w3.org/TR/owl-time/

"timex" is based on the paper (see docs folder): Alfred J. Reich. "Intervals, Points, and Branching Time. In S. D. Goodwin and H. J. Hamilton, editors, Proceedings of the TIME-94 International Workshop on Temporal Reasoning , pages 121–133, Regina, SK, Canada, 1994. University of Regina. http://www2.cs.uregina.ca/~temporal/time94/time-94-papers.html

The format of the file, timex.ttl, is "turtle" as described here: https://www.w3.org/TR/turtle/

In the docs folder, the file "reich-ascii-tbls.txt" includes four transitivity tables; one from the paper by J.F. Allen mentioned in the paper by A.J. Reich, and three from the paper by A.J. Reich:

• Interval Transitivity Table (Allen) <-- W3C Time describes the 13 relations here
• Interval & Point Transitivity Table (Reich) <-- timex.ttl describes how this connects to W3C Time
• Right Branching Interval & Point Transitivity Table (Reich)
• Left Branching Interval & Point Transitivity Table (Reich
