From the abstract:

The main goal of this document is to describe how e-Delivery platforms of existing Large Scale Pilots (PEPPOL, SPOCS and STORK) can converge towards a single solution, which is suitable for them as well as for the new LSP e-Codex. As underlined by the European Commission the acceptance and the support coming from the industry is a very important success factor. Therefore such a e-Delivery solution should also include industry standards like ebXML in the area of B2B and ETSI REM.
