    • SOA Challenge
    • OMG SOA SIG: Mission & Participants
    • OMG’s approach to SOA & Value Proposition
    • Summary of gap analysis effort
    • Summary of Standards in development

  • 3. SOA Challenge
    • Inadequate emphasis on
    • Business & Architectural
    • aspects of SOA
    • Poor (if any) traceability
    • of Services to business
    • processes & functions,
    • compliance..
    • Many standards organizations are developing standards with possible overlaps and rapid churn
    • Vendors are repositioning their products as SOA enabled, end-to-end solution and takeovers leaving the Consumer with the burden to identify the best of breed solution
    • ..We know this already…so what is OMG doing?
    http://www.innoq.com/soa/ws-standards/poster/
  • 4. SOA SIG Mission & Participants
    • Mission
    • Support a Model Driven Architecture (MDA) approach to SOA that links architectural, business and technology views of Services, including Business Process Management (BPM) and Event-Driven Architecture (EDA)
    • Identify and foster development of OMG modeling standards for SOA that integrate with and complement standards developed by other organizations such as W3C, Open Group and OASIS…

  • 5. Model Driven Architecture: “The DNA of SOA”
    • Unified Modeling Language
      • Addresses system modeling

Process Modeling Application, Service, Event Modeling Other.. Information Modeling Security, Performance, Testing, Compliance Modeling
  • 6. OMG’s Approach & Value Proposition
    • While other organizations have focused on specific standards for integration or web services protocols (e.g., WS-* standards), OMG complements their efforts by taking a Platform Independent View and applying a Modeling Approach to SOA
      • Modeling offers the capability to design a complete SOA solution
      • Intellectual property documented through models can have a longer lifespan, allowing an organization a choice of the best technical platform for SOA implementation
    Modeling is OMG’s Core Competence
  • 7. SOA Related Business Modeling Standards
    • Business Motivation Model (BMM)
      • Mission, goals and objectives for an organization linked to external factors
    • Semantics for Business Vocabulary and Rules (SBVR)
      • Combines natural language expression with precise logical underpinning
    • Business Process Modeling Notation (BPMN)
      • Existing standard from BPMI.org (merged into OMG)
    • Business Process Definition Metamodel (BPDM)
      • Notation and platform independent process modeling and interchange
    • Production Rules Representation (PRR)*
      • Platform independent model for executable rules
    • Business Process Runtime Interface (BPRI)*
      • Platform independent interfaces to running processes
    • Organization Structure Metamodel (OSM)*
      • Organizations, relationships, positions and roles
      • * in development
  • 8. SOA Related Technology Modeling Standards
    • UML
      • Architecture and design of services/internals

    • A common vocabulary and metamodel to unify the diverse service definitions that exist in the industry
    • Complement existing UML metamodel by defining an extension to UML to ensure complete and consistent service specifications and implementations
    • Integrate with and complement standards developed by other organizations such as W3C and OASIS
    • Support a service contract describing the collaboration between participating service consumers and service providers
    • Enable traceability between contracts specifying services requirements, service specifications that fulfill those requirements and service providers that realize service specifications

    • Summary of gap analysis effort
    • Summary of Standards in development
    • SOA Standards Harmonization activity
    • Next steps
  • 16. SOA Standards Harmonization Activity: Drivers
    • Many standards organizations are developing standards with possible overlaps and rapid churn
    • “ Just the mere number of standards and specifications that one has to consider when attempting SOA is mind numbing”..
        • Which ones are specifications (not yet standards) submitted to standard bodies?
        • Which ones are specifications ratified by the standard bodies as industry standards?
        • Which ones (standards or specifications) overlap (some do) and which to choose / use in such cases?
        • And worst of all, there is not a single place to go to for these standards!
        • http://blogs.sun.com/roller/page/alur?entry=soa_standards_overload_or_real
    • “ Given the proliferation of SOA standards, there is an opportunity to take a step back and provide some perspective on all the SOA standards that exist …”
    • http://searchwebservices.techtarget.com/tip/0,289483,sid26_gci1244481,00.html?track=NL-110&ad=581964&asrc=EM_NLN_1076649&uid=783626
  • 17. SOA Standards Harmonization Activity: Mission
    • Enable various standards organizations to reconcile their SOA efforts and offer clarity to the end-users lost in the maze of SOA standards
    • Prioritize and foster development of standards applicable to Business and Technology Dimensions of SOA
    • Enable standards organizations to become trusted advisors to the SOA community
  • 18. How do we Harmonize?
    • Develop and maintain an authoritative source of SOA and related standards (SOA Standards Knowledgebase)
      • Sponsored by OMG SOA SIG, being developed collaboratively with other standards organizations
      • Map SOA standards (proposed, in development or adopted) to ‘SOA Perspectives’
        • Business Perspective : Motivation (mapping Services to Business Functions), legal/compliance, Cost, discovery*, maturity*…
        • Architectural Perspective : Reference Models, Design-patterns…
        • IT Perspective
          • Information Perspective (Service Payload) : Data Distribution , Domain Standards…
          • Developer Perspective : Orchestration, Security, Protocols…
        • Publish a roadmap of who is developing which category of SOA standards
        • * can apply to more than one Perspective
      • For each Standard:
        • Name, description, current release/version (as applicable)
        • Life-cycle status (proposed, RFI, RFP, initial submission, adopted…)
          • Timeline
        • Responsible Organization
          • Link to the organization and its SOA standards roadmap, noteworthy news
          • (RSS feeds to keep the information current)
  • 19.  
  • 20.  
  • 21. Harmonization Activity: other examples
    • Use of OASIS’ SOA reference model and vocabulary in OMG’s SOA standards development as applicable
    • Discussions started with Everware-CBDI to harmonize their SOA metamodels with the OMG’s UPMS (additional joint RFP planned)
    • OMG working with Events Processing Technical Society (EPTS) on the development of modeling standards for EDA/CEP
      • The goal of EPTS is to promote the understanding of the “event processing” area, its potential impact and serve as a catalyst to the growth and understanding of the area by the general technical and business community
        • Collaborating with The Events Processing Reference Architecture Working Group on CEP/EDA patterns and extensions to OMG standards relevant to events processing
  • 22. SIG next steps
    • UPMS adoption- March 2008
    • EDA RFP- to be issued in Dec. 2007, initial submission March 2008
