The Relationship_ID says, all Nodes with the same Relationsship_ID, are connencted to each other, respectively have a edge between it. So I need as result a Edge-table, which look likes the following:
Download the file and save the component (double click and then click finish) and use it in your workflow by dragging and dropping it from the “KNIME Explorer” pane (components come after the workflows in the list).
Agree with @Aswin on this one. Less is more! Only one thing I would add/change. I wouldn’t perform filtering on Node names cause this names can be dummy and won’t work on KNIME node names for example So I would add integer Counter (either with Rule Engine or Counter Generation) prior to Joiner node and in Rule-based Row Filter would filter based it.
