ISO/TS 24533:2012 specifies the data concepts applicable to the movement of freight and its intermodal transfer. These data concepts include information entities (data elements), aggregated/associated information entities (groups of data elements) and messages that comprise information exchanges at transport interfaces along the chain of participants responsible for the delivery of goods from the point of origin through to the final recipient. ISO/TS 24533 focuses on a single "thread" of the overall end-to-end supply chain.
