  2. This Talk • Introduction • Background • UniFrame • Model Integrated Computing (MIC) • Overview of the Approach • Modeling Web Service • Conclusion

  3. Introduction • System Integration • EAI:Enterprise Application Integration • Proprietary • OMG MDA: Model Driven Architecture • PIM/PSM • Re-engineering/Mapping • Web Services • Open Standard: XML/HTTP • Weak in Semantics • The Benefits of Modeling Web Services • Clearly represent the service-oriented architecture • Enrich the semantics via existing facility used for enriching UML semantics • Automate code generation (WSDL)

  4. Background • UniFrame • A Framework for seamless interoperation of heterogeneous components distributed Components • Component Specification • Component Service Integration • Model Integrated Computing (MIC) • Domain-Specific Modeling • Model Based Generator

  5. Overview of the Approach

  6. Big Picture: WSDL Generator 1 Domain-Specific Model Legacy System Wrapping Domain-Specific Meta Model

  7. Modeling Web Service • Create Meta-Model • Enrich Semantics over Meta-model • OCL • Finite State Machine • …. • A Web Service Modeling Environment • Create Web Services Model • Generate Enriched WSDL

  8. Meta-model of WSDL porttype operation message part 1..* port service binding 1..* 1 1 type input output

  9. message operation Meta-Model of Banking Domain

  10. Web Services Modeling Environment

  11. Meta-model of Finite State Machine

  12. A Banking Behavior Model Based On FSM Meta-model

  13. Demo

  14. Conclusion & Future Work • A Model Based Approach to Web Service • Future Work • Meta-model composition • More behavior modeling • Web Services based integration of heterogeneous components
