 <h4>Temporal Events</h4>
 Four kinds of discrete events underpin the PROV-DM data model. They are:
 <ol>
-<li>Generation of an entity by a process execution:  identifies the final instant of an entity's creation timespan, after which the characterized thing represented by an entity becomes available for use.</li>
-<li>Use of an entity by a process execution:  identifies the first instant of an entity's consumption timespan.</li>
-<li>Start of a process execution: identifies the instant an activity represented by a process execution starts</li>
-<li>End of a process execution: identifies the instant an activity represented by a process execution ends</li>
