scope:

The present document establishes guidance on architectures and requirements for tools to be considered when deploying cross-border electronic procurement systems using technical specifications defined in this CWA in the form of Business Profiles. When implementing electronic procurement systems in a pan-European cross-border environment, there are different aspects to be covered to solve interoperability issues that arise due to the lack of a European-wide common legislation or to the different standards or tools that may address a specific issue. The present document is applicable to security, contents and transport issues that arise when deploying the technical specifications in Part 1 of this CWA. The main purpose of the present document is to provide information on alternatives and recommendations on the main aspects applicable when implementing profiles to build electronic procurement systems. Although the main focus is on public procurement procedures where legal aspects apply, the same tools and architectures can be used when developing and deploying electronic procurement systems in the private sector.
