Table pub.mgd.dag_node
A record in this table represents a specific Node within a DAG. The _Object_key/DAG_DAG._MGIType_key combination
identifies the specific Node object. In the case of a GO DAG, this is a specific Vocabulary Term.
The DAG_DAG._MGIType_key identifies the type of object (a Vocabulary Term) and the _Object_key identifies the
object itself.
