scope:

This CWA is a deliverable of the second CEN Workshop on Business Interoperability Interfaces for public procurement in Europe (WS/BII2). The objective of the BII initiative is to provide a framework for interoperability in pan-European electronic procurement transactions, expressed as a set of requirements and technical specifications. The requirements are input into UN/CEFACT in order to ensure global interoperability. The original CEN Workshop on Business Interoperability Interfaces for public procurement in Europe (WS/BII) was concluded in December 2009, and its results, including a set of profiles, were issued as CWA 16073:2010. Based on user input WS/BII2 has issued a number of new profiles and reviewed and updated a number of the profiles published as part of CWA 16073:2010. WS/BII2 profiles A WS/BII2 profile description is a technical specification describing - the scope of a business process with its goals, preconditions and the roles of participating parties, - the choreography of the business process covered, i.e. a detailed description of the way the business partners collaborate to play their respective roles and share responsibilities to achieve mutually agreed goals with the support of their respective information systems, - the electronic business transactions exchanged as part of the business process, with their information requirements, and the sequence in which these transactions are exchanged, - the business rules governing the execution of that business process, as well as any constraints on information elements used in the information requirement models of the transactions. The profiles focus on the standardization on the organisational and semantics interoperability levels rather than on syntax or technical interoperability levels. Consequently the business transactions within a profile can be structured based on different message standards/syntaxes as long as these can carry all the necessary information elements. Although ...
