1. Defining a federated messaging and trust infrastructure for secure and reliable exchange of data Kenneth Bengtsson OASIS Business Document Exchange (BDXR) TC 20 th UN/CEFACT Forum Vienna, 19 September 2012

2. OASIS Business Document eXchange TC Describes an architecture where trading partners exchange documents securely and reliably through the use of gateways Also known as the 4-corner (or multi- cornered) model

3. Peer-to-peer model Not scalable – Need to agree and implement standards for transport and content with each trading partner one at a time Difficult to match business requirements and capabilities – Individuals, SMEs, large companies and governments all have very different requirements, capabilities and resources – Technical requirements (trust, service levels etc.) raise the barrier Trading partner

4. Three-corner model Proprietary standards (whole stack) Risk of service provider lock-in / limited competition Customers may have to connect to several service providers Trading partner Service provider Customer relationship Customer relationship

5. Four-corner model Lowers barriers by allowing for different business models – Requirements and capabilities differs greatly between individuals, SMEs, large companies and governments. Freedom to choose service provider Leverages investments in existing infrastructures by connecting clouds Trading partner Service provider / gateway Customer relationship Customer relationship Service provider / gateway Standardized interface

6. PEPPOL’s multi-cornered infrastructure

7. Governance and trust Trading partner Service provider / gateway Agree upon: SLA requirements Standardized business processes Standardized business documents Standardized transport profiles Trust and certificate validation
