Model-Driven SOAOMG SOA SIG Activity Debrief June 28th 2007 Dr. Harsh W. Sharma, Co-Chair, OMG SOA SIG James Odell, Co-Chair, OMG SOA SIG Pete Rivett, Chair-Emeritus, OMG SOA SIG
Agenda • SOA Challenge • OMG SOA SIG: Mission & Participants • OMG’s approach to SOA & Value Proposition • Summary of gap analysis effort • Summary of Standards in development • SOA Standards Harmonization activity • SIG Next Steps
SOA Challenge http://www.innoq.com/soa/ws-standards/poster/ • 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?
MDA EA/Business Models BPM SOA EDA Other… J2EE Relational .NET Implementation Stacks 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… Participants • IBM, HP, SAP, BEA, Unisys, EDS, RTI, Model Driven Systems, Adaptive, MEGA, MetLife, VISA, Bank of America, CitiGroup, Boeing, Raytheon, Rhysome, AptSoft, XAware, SOA COP, SOA Consortium, The Open Group, OASIS, Satyam, US EPA, ebizQ, Georgetown University, NIST, Liberty-Mutual, Penn National, Prima-Solutions, OSOA, Nortel, Indiana University…
Security, Performance, Testing, Compliance Modeling Business Modeling (motivation, Intent..) Process Modeling Information Modeling Application, Service, Event Modeling Other.. MOF/XMI Facilities for defining, interchanging, transformation and managing All models and metamodels Model Driven Architecture: “The DNA of SOA” • Unified Modeling Language • Addresses system modeling • Common Warehouse Metamodel/Information Management Metamodel (IMM) • Addresses information modeling & metadata exchange • Traceability of information (source to targets) • Meta Object Facility • Addresses the definition of modeling languages (metamodels) • Integration, interchange and management of models Core MDAStandards are ISO Standards
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
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
SOA Related Technology Modeling Standards • UML • Architecture and design of services/internals • General purpose modeling language (via UML Profiles) • Reusable Asset Specification (RAS) • Packaging of reusable assets for retrieval, usage and deployment • CWM and forthcoming Information Management Metamodel (IMM) • Service Payloads (information content) and mapping to enterprise data sources • Ontology Definition Metamodel (ODM) • Modeling Ontology of ‘Services’ and Events’ • Facilitate development of Semantic Web Services • Knowledge Discovery Metamodel (KDM) • Models of the enterprise systems to which services typically map • Software Process Engineering Metamodel (SPEM) • Modeling the SOA development process (Service Life cycle)

OMG Standards apply to all layers of SOA http://www.omg.org/attachments/pdf/OMG-and-the-SOA.pdf
Summary of Gap Analysis Effort • Modeling approach to SOA* • Service Traceability to Business Processes* • Service Relationship to Events* • Need to Harmonize development of SOA Standards* • Service Discovery & Assets • SOA Life Cycle Metrics and Maturity • SOA Governance & Compliance *Gaps OMG SOA SIG started working on
Standards in Development • UML Profile and Metamodel for Software Services (UPMS) RFP • MOF metamodel and equivalent UML2 profile • Extend, but not conflict with UML semantics • Notation icons for services extensions http://www.omg.org/cgi-bin/doc?soa/06-09-09 • Event Driven Architecture (EDA) and its relationship with SOA, BPM – RFP (to be issued in Dec. 07) • Addresses Event vocabulary, relationship between EDA, BPM and SOA • Event Metamodel and UML Profile • Event metadata exchange using standard formats like XMI • Event Traceability and causality in relation to Services • Processing of complex events
UPMS Goals (submission in progress) • 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 • The ability to exchange services models between tools using XMI
Who is working on UPMS? • IBM • Adaptive • Cap Gemini • EDS • HP • Model Driven Solutions • Telelogic • BAE Systems • Azora • everware-cbdi • France Telecom R&D • The Thales Group • European Software Institute, • Softteam, • Rhysome and • MIDt • SINTEF • University of Augsburg, • NKUA – University of Athens • German Research Center for Artificial Intelligence (DFKI) • Oslo Software • DERI (University of Innsbruck) • Fujitsu • Mega International
Agenda • SOA Challenge • OMG SOA SIG: Mission & Participants • OMG’s approach to SOA & Value Proposition • Summary of gap analysis effort • Summary of Standards in development • SOA Standards Harmonization activity • Next steps
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
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
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)
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
SIG next steps • UPMS adoption- March 2008 • EDA RFP- to be issued in Dec. 2007, initial submission March 2008 • SOA Standards Knowledgebase – in development, beta rollout Sept.-Oct. 2007 • Domain specific ‘Business Services’ • Insurance • Define Property and Casualty Services – RFP planned • Scope discussion planned for Sept. SOA SIG-OMG Insurance WG meeting • White paper “Business Agility: Is SOA Enough” –by SOA SIG, Sept. 2007
