+
+we have in some sections
+Parent nodes from our code , which they are actually child nodes in the github issue .
+
+publisher is parent node , which it suits the child node from
+the serial node
+_title is also the same which it suits the title in the serial parent node
+
+in references and review parent nodes we have also some the same   
+
+
+Missing nodes are : links , rights  
+  
+the first node is ours and the response represents the  node of the github issue.   
+
+below you can see an instance about some complexity with the nodes    
+this is the review parent node with its child nodes
