 <h3>Component 1: Entities and Activities</h3>
 
 <p>The first component of PROV-DM is concerned with <a title="entity">entities</a> and <a title="activity">activities</a>, and their interrelations: <a>Usage</a>, <a>Generation</a>, <a>Start</a>, <a>End</a>, <a>Invalidation</a>, and <a>Communication</a>.  <a href="#figure-component1">Figure 5</a> uses UML to depict the first component.
-Core structures are displayed in the yellow area, consisting of two classes (<a>Entity</a>, <a>Activity</a>) and two binary associations between them (<a>Usage</a>, <a>Generation</a>). The rest of the figure displays extended structures, including UML associations classes (represented in gray) to express expanded n-ary relations (for <a>Usage</a>, <a>Generation</a>, <a>Invalidation</a>, <a>Start</a>, <a>End</a>,  <a>Communication</a>). The figure also makes explicit associations with <em>time</em> for these concepts (time being marked with the primitive stereotype).
