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-toend 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?

5
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 is OMG’s Core Competence
 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

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
11
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
12
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

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
15
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…”

16
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
17
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
21
SIG next steps
