 <h2>Data Model Refinement</h2>
 
 <p>Underpinning the PROV-DM data model is a notion of event, marking transitions in the world (when entities are generated, used, or destroyed, or activities started or ended).  This notion of event is not first-class in the data model, but underpins many of its concepts and its semantics [[PROV-SEM]].  Thus, using this notion of event, we can provide an interpretation for the data model, which in turn can allow creators of provenance assertions to make their assertions more robust. </p>
