On the other hand, the contact element has a mandatory aid attribute that must point to the id attribute of the contacting author of the current paper.

Since the paper element is shared by the conf and cite elements (two incoming edges in a DTD graph), new elds parent elm, fk conf and fk cite are added to record who and where the parent node was. Note that in the paper table of Table1 , a tuple with id= quot;p7 quot; has the value quot;paper quot; for the root elm eld.
