+            The Biolink association type (entity) that this edge represents.
+            Associations are classes in Biolink
+            that represent a relationship between two entities.
+            For example, the association 'gene interacts with gene'
+            is represented by the Biolink class,
+            'biolink:GeneToGeneAssociation'.  If association
+            is filled out, then the testing harness can
+            help validate that the qualifiers are being used
+            correctly.
+          example: biolink:ChemicalToGeneAssociation

         - subject
         - predicate
         - object
