OiCoN 2007Madeira Island AIAG Inventory Visibility & Integration Project (IV&I)  Optimize Supply Chain through better Business Collaboration  Leverage XML Messaging Public Internet  Shared Semantics OAGI XML Vocabulary Joint Automotive Data Model (in progress; jointly with Odette, JAMA,…) ATHENA (research)  Considered several competing protocols Web Services ebXML AS2  Currently focused on Web Services

OiCoN 2007Madeira Island Why Web Services?  Ubiquitous (but still maturing)  Interoperability Web Services Interoperability (WS-I) Profiles Basic; Basic Security; & Reliable Secure  Service Oriented SOA already used for internal integration Extend Service Oriented Concepts to B2B integration  Provide a ‘process’ context Not just ‘message slinging’  Reasonably complete ‘stack’ Semantics (XML Schema) Security Reliability Orchestration Transactions Directory Metadata driven (WSDL, Policy, BPEL)

OiCoN 2007Madeira Island But Something is Still Missing  Web Services based SOA Provides a Lot But… No clear way of defining Business Collaboration »Across Multiple Partners BPEL provides a single-node view only How to link multiple, independent nodes  Business Collaboration Specification (BCS) Attempts to fill this gap

OiCoN 2007Madeira Island BCS: SOA + UML Modeling SOA Protocol Stack SOA Protocol Services Business Services StatelessState-full SOA Protocol Stack SOA Protocol Services Business Services StatelessState-full SOA Protocol Stack SOA Protocol Services Business Services StatelessState-full Partner APartner BPartner C BCS: UML-based methodology for Modeling Collaborations

OiCoN 2007Madeira Island BCS Concepts Partner A Partner B A Business Collaboration is modeled as a UML Activity Diagram. Each ‘Swimlane’ represents a collaboration Partner Each ‘ActionState’ represents some activity that a partner is expected to do, e.g. send or receive a message. Each ‘ObjectFlowState’ represents a message Control flows from one activity to another but cannot cross ‘Swimlanes’ (BCS rule) Only message flows can cross ‘Swimlanes’

OiCoN 2007Madeira Island BCS Sample: Parallel Processing Models a collaboration where ‘A’ is required to send two messages to ‘B’ and ‘B’ is required to wait for both before proceeding. Messages may be sent or received in any order.

OiCoN 2007Madeira Island BCS Summary  The set of Activities and Control Flows in a ‘Swimlane’ describe a Partner's collaboration ‘state machine’ (process)  A ‘Business Collaboration’ is a set of processes and their coordination via message flows – a ‘Meta Process’  Gives each partner visibility to the relevant portions of other partners’ processes  Each partner is free to extend it’s process for internal processing as long as the external view is not affected ‘Reference Implementation’ available for MagicDraw™ UML Tool
