An information exchange platform referred to as a Trading Grid (TG) may perform relationship-based data processing utilizing a trading partner (TP) graph that describes relationships amongst operating units (OUs) on the TG. When the TG receives a request from an OU to exchange data with a TP, the TG accesses the TP graph and determines a relationship between the OU and their TP as reflected in the TP graph. The TP graph is maintained and controlled by the system independently of the OU and the TP. The TG may route the data based on instructions associated with the relationship that is reflected in the TP graph. The instructions associated with the relationship may specify network based services provided by the TG. An orchestration component may operate to orchestrate the performance of the network based services. The TG then communicates the processed and/or produced data to the TP.
