In the interest of anticipating and following technological trends, UN/CEFACT is extending from a document-centric to a process-driven approach for electronic business message development.
The UN/CEFACT Supply Chain Reference Data Model (SCRDM) is a standardized and harmonized semantic framework fully compliant with the UN/CEFACT Core Component Library. The SCRDM focusses on interoperability, re-use of supply chain core components (globally standardised semantics), and will speed-up and ease implementation. It builds the foundation for deriving syntax-neutral CCBDA compliant semantic business document models.
A proof-of-concept  project about the type of artefacts for this project has been completed April 12, 2016. This project proposal will target the Cross Industry Invoice (CII) as a next step. 
The purpose of this project is to develop the technical artefacts needed in order to allow users to implement the CII based on the SCRDM and Core Component Business Document Assembly (CCBDA).
