As used by the U.S. Bureau of the Census, a graph containing nodes (corresponding to fields) which are connected by arcs (an arc between two nodes indicates that the two fields are involved in an edit failure.) Deleting a node is equivalent to choosing that field to be imputed. A minimal set of deleted nodes is equivalent to a minimal set as defined by Fellegi and Holt.
