Definition
«Material» relation can be completely derived (via «Derivation») from the «Relator» and the corresponding «Mediation» relations. Derivation makes the cardinality constraints of the mediation relations collapse (see «Material» relation, example 2).
Also, several «Material» relations can be derived from a single «Relator» and «Mediation» relations (see «Material» relation, example 1).
