4. Selected Standard Initiatives
 We give an overview of the newest OMG modelling standard
initiatives with respect to enterprise architecture.

models that can be used to describe and understand how different
aspects of an enterprise work together.
 A framework for enterprise architecture was first introduced by Zachman
in 1987

7. OMG and Interoperability
 Enterprise Architecture
 Zachman Framework introduced in 1987.
 Today there exists several, e.g., DoDAF, MODAF, TOGAF.
 Regardless of the differences between the enterprise
architectures,
 the models within them must all represent the goals, processes,
rules, IT resources and relationships
 that define how the enterprise operates.
 Since all of OMG’s modelling specifications are based on
 a common modelling infrastructure, namely the Meta-Object
Facility (MOF),
 using OMG modelling standards help tie individual models
together in an overall architecture.
ICT

8. Metamodelling
 System development is fundamentally based on the use of
languages to capture and relate different aspects of the
problem domain.
 The benefit of metamodelling is its ability to describe these
languages in a unified way.
 This means that the languages can be uniformly managed and
manipulated thus tackling the problem of language diversity.
 For instance, mappings can be constructed between any number
of languages provided that they are described in the same
metamodelling language.
 Using metamodels, many different abstractions can be defined
and combined to create new languages that are specifically
tailored for a particular application domain.

11. Business Modelling Specifications (1/2)
 Business Motivation Model (BMM)
 Implementing enterprise
architecture typically starts with
documenting goals, strategy and
business plans.
 BMM defines a set of concepts
(e.g., goal, objective, vision, means
and strategy) that can be used to
model the elements of business
plans.
 These elements can be linked to
business roles, business rules and
organization unit that are specified
using other OMG modelling
standards.
 Business Process Modeling
Notation (BPMN)
 BPMN 2.0 is in the final stages of
standards adoption at OMG.
 The specification provides a
notation and a model for business
processes and an interchange
format.
 BPMN is designed to cover many
types of modelling and allows the
creation of end-to-end business
processes.
 It allows the specification of private
processes (both non-executable
and executable), public processes,
choreographies and collaborations.
ICT

12. Business Modelling Specifications (2/2)
 Value Delivery Metamodel (VDM)
 This RFP solicits proposals for a
metamodel specification for
modelling customer value delivery.
 Integrated value delivery models
provide context for understanding
the impact of services on multiple
lines of business.
 These models also provide the
context for sharing services.
 They make cost and time analysis,
in the context of strategic planning
and transformation, more efficient
by formalizing the structure of the
value delivery system.
 Case Management Process
Modeling (CMPM)
 This RFP solicits proposals for a
metamodel extension to BPMN 2.0
to support modelling of case
management processes.
 Case Management focuses on
actions to resolve a case – a
situation to be managed toward
objectives.
 Cases don’t have predefined
processes for achieving objectives.
 Humans make decisions based on
observations, experience and the
case file.
ICT

13. BPMN History
 The Business Process Management Institute (BPMI – now
a part of the OMG) develops BPML and realizes the need
for a graphical notation
 BPML was later replaced by BPEL as the target execution
language
 August 2001, the Notation Working Group is formed.
 May 2004, the BPMN 1.0 specification was released.
 BPMN1.x
 BPMN 1.0 adopted as an OMG standard – February 2006
 BPMN 1.1 (OMG) – January 2008
 BPMN 1.2 (OMG) – January 2009
 BPMN 2.0 expected finalized June 2010

14. New Features in BPMN 2.0
 Formal metamodel specified in MOF
 Interchange formats for model and diagram interchange
 New process elements
 Non-interrupting events
 Event sub-process
 New data elements
 New interaction diagrams
 Conversation
 Choreography

15. Conversation Diagram
 A Conversation is set of
Message exchanges (Message
Flow) that share the same
Correlation.

 Conversation diagram depicting
several conversations between
Participants in a related
domain.
ICT

16. Choreography Diagram
 Provides a flowchart view to sequence interactions between
Participants
 Choreographies define a “business contract” or protocol to which the
Participants agree to follow during real-time interactions.

18. SoaML Goals
 Intuitive and complete support for modelling services in UML
 Support for bi-directional asynchronous services between multiple
parties
 Support for Services Architectures where parties provide and use
multiple services.
 Support for services defined to contain other services
 Easily mapped to and made part of a business process
specification
 Compatibility with UML, BPDM and BPMN for business processes
 Direct mapping to web services
 Top-down, bottom up or meet-in-the-middle modelling
 Design by contract or dynamic adaptation of services
 To specify and relate the service capability and its contract
 No changes to UML
ICT

19. SoaML Key Concepts
 Services architecture – specification of community
 Participants – role
 Service contracts – collaboration (provide and consume)
 Service contract – specification of service
 Role – Provider and consumer
 Interfaces
 Choreography (protocol, behaviour)
 Service interface – bi-directional service
 Simple interface – one-directional service

service
 A ServicesArchitecture (or SOA) is a network of participant roles providing and
consuming services to fulfil a purpose.
 The services architecture defines the requirements for the types of participants and
service realizations that fulfil those roles.
 The services architecture puts a set of services in context and shows how participants
work together for a community or organization without required process management.
 A community ServicesArchitecture is defined using a UML Collaboration.

23. Service interfaces: ShippingService
 The ShippingService service
interface refines the
ShippingContract service
contract.
 The ShippingService service
interface involves two roles:
 The shipper role is a provider
role. It is responsible for
fulfilling the shipping
responsibilities that are given
by its type, the shipping
interface.
 The orderer role is responsible
for processing the shipping
schedule. This is shown by its
ScheduleProcessing type.
ICT

24. Message-centric vs. RPC-style services
 There are several SOA interaction
paradigms in common use including
document centric messaging, remote
procedure calls (RPC), and publishsubscribe.
 The decision depends on cohesion and
coupling, state management, distributed
transactions, performance, granularity,
synchronization, ease of development
and maintenance, and best practices.
 SoaML supports both document-centric
messaging and RPC-style service data.
 Service data is data that is exchanged
between service consumers and
providers. The data types of parameters
for service operations are typed by a
DataType, PrimitiveType, or
MessageType.
ICT

25. Service realization: Composite structures
 A ServiceInterface can be the type of a service port.
 The type of a Request port is also a ServiceInterface. The Request port is the conjugate
of a Service port in that it defines the use of a service rather than its provision.
 This will allow us to connect service providers and consumers in a Participant.
 Each service operation provided by a service provider must be realized by either a
behavior or an action.
ICT

26. Conclusions
 OMG should be regarded as an important industry
consortium that standardizes and promotes many relevant
specifications to support interoperability.
 One important benefit of using OMG standards is that all
standards are based on the common modelling
infrastructure MOF, which ensures that the models are
tied together in an overall architecture.
 This has the advantage that tools and methodologies that
are based on OMG standards will be able to exchange
models and interpret the different models.
