  4. Semantic Service-Oriented Architecture (NLL, OWL(-s), UBL,…) Semantic Web Service Service-Oriented Architecture （XML,SOAP,HTTP, …） Web Service Middleware （CORBA,J2EE…） Messages Component Object Evolution of Software Paradigm (1/2) Granularity of Software Modular Time 1990’s 21 Century 1980’s

  5. Evolution of Software Paradigm (2/2) • Web Services (WS) can be deemed as • Basic modular for software development • Popular form of web-based applications • Specification related to different aspects of WS • Service Oriented Architecture (SOA) • Description languages: OWL-s, WSDL,… • Web Services registry mechanism: UDDI • …… • Web service is a kind of process model

  6. What is Process • Process is defined as • a set of work items, scheduled according to constraints, which all participate in fulfilling a common purpose. [Breton, 2001] • transformation of input to output. [ISO/IEC 12207] • Structured set of activities involving various enterprises entities, that is designed and organized for a given purpose. [ISO 18629-1, 2004] • one or more activities that occurs over a period of time in which objects participate. [Cutting-Decelle Anne-Francoise, 2005 ]

  7. What is Process Model • Process models are • carriers of process knowledge, concerning how to do things [John, 2006] • the products of process modeling that is described with a certain process modeling language • In general, process models are deemed as a special kind of information model with behavioral features • State transfer • Data exchange • …… include • Web services, business process, workflow, etc.

  8. ? ? ? How to make them work together in a harmonious and effective way? Why we need MFI-5 (1/3) • Business cooperation and web service composition are more and more popular in current practice within/across enterprises. Purpose/Objective Activities Steps/Orchestration Actors & Roles

  9. Personalized Requirements expressedAs Goal achievedBy partOf partOf Process partOf partOf interoperate achievedBy achievedBy Process 1 Process 2 Goal 2 Goal 1 Different expressions, formats and implementation details Why we need MFI-5 (2/3) Registration is the basis of interoperationand further integrationof process models.

  10. Why we need MFI-5 (3/3) • MFI family focuses on the various kinds of information resources • MFI Core provides a very generic framework for various models. • Insufficient to deal with input and output messages, which are the basic component of process model • MFI Ontology Registration • provides a facility to register administrative and evolution information of ontologies. • A new part is needed to enable interoperation between process models and support further customized construction based on them. • Problems to be tackled in MFI-5 is to provide a facility to register the administrative information about process models • Structural info • Semantics

  15. Scope of MFI-5 (1/3) • Objective • Provide a metamodel to register process models, including business process model, web service and so on. • Focus on the relationship between process model described with different process description languages, especially the composite process consists of sub-processes expressed in different languages. • Promote semantic interoperation between various process models. • Support process integration within/across organizations

  16. MFI Core Scope of MFI Process registration MFI Ontology Registration Scope of MFI-3 MFI Process registration Admin. Info. A Admin. Info. B Ontology registry Process model registry Administrative information of process model A Administrative information of process model B referredTo Process model repository Process model A for application system A Process model B for application system B support Application system B Application system A interoperation Scope of MFI-5 (2/3) Specifications such as PSL

  17. Scope of MFI-5 (3/3) • Points in the scope of MFI-5 • Structural information of process model • Which sub-processes are contained in process model • Which artifact participate in fulfilling the common purpose • Semantic constraints of process model • Semantic relation/contradiction between artifacts • Condition • Mandatory sequence • Precondition and postcondition • …… • Outside the scope of MFI-5 • Language specific details • Implementation level details

  18. Structural Info Process model expressed in different modeling languages Semantic Info • Actual execution • 12(2.12.2)3 • Control_Constraint • Condition: precondition/postcondition • Control Construct: Sequence 2(2.12.2)3 CP 1 3 2 AP1 CP1 AP2 2.1 2.2 abstract AP3 AP4 Output1 • Artifact_Constraint: semantic consistency between artifacts carried by Input/Output CP1 Output3 Input2 Ontology Output1 Input1 AP3 Input1 Output2 Input3 supports Input2 Output3 AP4 Basic idea of MFI-5

  19. Base Model Process Control Model Overview of MFI-5 MFI-5

  20. Base Model (1/2) • Base Model is proposed to register structure information of various process models • Goal: the purpose that should be achieved by fulfilling the process model • Artifact: the resources that participate in the process, which can be carried by its Inputs or Outputs • Atomic Process: the process model characterized with the smallest granularity and one-step execution • Composite Process: the complicated process model which is composed of at least two sub-processes.

  21. Base Model (1/2)

  22. Process Control Model (1/3) • Process Control Model is defined to record two kinds of control constraints in process models • Artifact_Constraint • Added to Artifact • From registration info of ontologies based on MFI-3 • Usage • establish a semantic bridge between different Artifacts • support input/output matching between different process models • Semantically annotate specified Artifact • avoid semantic confliction during process integration

  23. Process Control Model (2/3) • Control_Constraint • Added to Process • Consists of • The conditions that should be satisfied before or after execution of the process model • The sequence followed by the sub-processes • Specially the conditions carried by control constructs, which are used to connect the sub-processes.
