The UN/CEFACT Buy-Ship-Pay (BSP) Reference Data Model (RDM) has been developed with the aim of bridging the Supply Chain RDM and the Multimodal Transport RDMs which, although both based on the UN Core Component Library (CCL), differ in the way international sales and transport contract data is treated. Effectively creating an intermediary subset, this higher level RDM will cover “Buy”, “Ship” and “Pay” components and will enable more efficient data maintenance. The Business Requirement Specifications (BRS) provide a high-level description of the amalgamation of the current separate BRSs for SCRDM and MMT-RDM.
