relationship([b=boolean], [relationshipData=string])

Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.

relationship is undoable, queryable, and editable.

This is primarily for use with file IO. Rather than write out the specific attributes/connections required to maintain a relationship, a description of the related nodes/plugs is written instead. The relationship must have an owner node, and have a specific type. During file read, maya will make the connections and/or set the data necessary to represent the realtionship in the dependency graph.
