-      <a href="#hadPrimarySource" class="qname">prov:hadPrimarySource</a> cites an ancestor Entity produced by some agent with direct experience and 
+      by repeating some or all of the original, 
+      <a href="#wasRevisionOf" class="qname">prov:wasRevisionOf</a> indicates that the derived Entity contains substantial content from the original Entity

+      <a href="#hadPrimarySource" class="qname">prov:hadPrimarySource</a> cites an older Entity produced by some agent with direct experience and 
       knowledge about the topic (such as a reading from a sensor, or a journal written during an historical event).
