Defining specifications for multi-cornered
messaging infrastructures
Secure and reliable exchange of
information
Content agnostic
Defining both trust and messaging
standards
Base on existing and proven technologies
wherever possible

Roadmap for OASIS BDX
PEPPOL
specifications and
requirements have
been submitted
• Other European
LSPs have
submitted
requirements as
well
Gather further
requirements and
analyze use cases
Specifications for a
unified architecture

reliable exchange of

Why use a four-corner
model?
n
n
Connecting existing infrastructures rather than creating a new
“island among the islands”
Freedom to choose service provider and avoiding lock-ins
l
n
Avoiding the need to connect to multiple providers
The requirements differs a lot between service providers, large
companies and SME’s
l
Trust requirements raise the barrier
n
l
Low-latency and availability requirements raise the barrier
n
l
The technical solution requires a trusted third-party
Requires hosted services with good SLA
No single transport profile matches all the requirements. The
four-corner model caters for this inherent problem
Why is the SMP separate
from the Access Point?
Metadata

Orthogonal
Can use metadata without agreed

Can use transport protocol without
looking up metadata
l
e.g. hardcoded endpoints
Allows new protocols to be added
Allows alternate governance models
