The CEN BII workshop aims to identify and document business interoperability interfaces to enable pan-European e-procurement. It has developed CWA's (CEN Workshop Agreements) that define profiles, convergence of UBL and CEFACT standards, tools, and pilot project support. Implementing the CWA's through projects like PEPPOL will increase interoperability between systems using UBL and CEFACT standards for electronic business document exchange across Europe.
