2. Outline
• The Merchant Dilemma
• Solution Architecture
– Use best of breed components
– Integrate them with a simple service bus
– Standardize processes not documents
• X.commerce platform
– Define global choreographies using XOCL
– Generate wire encodings, documentation, runtime metadata
– Services implement local orchestrations
– Service bus coordinates distributed transactions
• A lap around XOCL
• Current status

Back office
8. Using a Service Bus
Ad Hoc Integration Service Bus
Merchant Service Merchant Service
Systems Providers Systems Providers
Merchant benefit: Access to new capabilities, lower switching costs
Developer benefit: Exposure to new merchants, better cost amortization

13. The Problem With Documents
Lack of context
• Different • Less than 3% of
participants have document
different • Aggregate behavior
undefined • (n**2 – n)/2
requirements implementations for
• Must be encoded n participants
into unused
Overloaded document fields Point to point
properties agreements
14. Standardizing Processes
Context specific
Business signals
• Define messages • Shared identity
individual and • Just enough and lifecycle • Two phase
aggregate data to commit
behavior synchronize • Demonstrate
state intent
Global Private entity
choreographies structure
15. Choreography and Orchestration
Send 1 Receive 5
A D
Receive 2 Send 6
Receive 1 B C Receive 3
Send 2 Send 4
Send 3 Send 5
Receive 4 • Global choreography can Receive 6
be audited
• Local orchestrations can
be automated with
workflow engines

16. UN/CEFACT Modeling Methodology
• No signals • Signal receipt • Response • Request is a query
• Signal validation indicates success • Response is
or failure results
• May contain data
Inform Notify Response Query

23. Types
Package
Type
Has
Message
• A message has a type, and types may
contain instances of other types.
• Types defined in XOCL map 1 for 1 onto
AVDL equivalents.

24. Contracts
Package Capability Bundle
Contract
• A contract is a named set of roles.
• A capability must implement all of the roles
in a contract.
• A bundle is a set of capabilities that Roles
implements a set of contracts to enact one
or more business processes.
