This CWA addresses the next step of standardization for the data exchange within an infrastructure shared by business partners. The focus is the semantics of the public procurement business processes built by xml based vocabularies specified by UBL 2.0 and UN/CEFACT core components. This is expressed in the CWA profile descriptions. A profile description is a technical specification describing:
- The choreography of the business processes.
- The business rules governing the execution of these business processes.
