Schedule
•week 1: Tuesday January 4, 2011 (room S648), 9:00-12:45, (guest lecturer: Richard Bakker,
IBM)
Tooling, Teaming & Installation. Presentation and demonstration on Rational Software
Architect and the Rational Team Concert environment. Distribution & installation of the
tools. Home work: perform the supplied tutorial; read the developerWorks articles.
•week 2: Tuesday January 11, 2011 (room S648), 9:00-12:45, (guest lecturer: Richard
Bakker, IBM)
Modeling with RSA and the SoaML extension. Working session with the teams and scope
team project, select a development process to follow. Working session where students
start modeling their solution.
•week 3: Tuesday January 18, 2011 (room P656), 9:00-12:45, (guest lecturer: Richard
Bakker, IBM)
Transforming each team’s SoaML model into an implementation. Describe the
requirements the transformation puts on the input model, elaborate the generated
implementation into a working system. After this session, the students should start with
their models and RSA and transform this into an implementation, which they test and
improve for the next two weeks.
•week 4: Tuesday January 25, 2011 (room C648), 9:00-12:45, (guest lecturer: Ton van
Velzen, IBM)
Introduction to the engineering of a cloud-environment; which requirements are unique to
a cloud solution and which specific software was selected to make this cloud feasible.
The case described will be the cloud that the students are utilizing.
•week 5: Tuesday February 1, 2011 (room S640), 9:00-12:45 (IBM and VU)

SoaML is…
 An Object Management Group emerging standard for describing
systems using service-oriented concepts
 Not yet finalized – expected to be up for vote at the OMG’s December
meeting
 Supported by many of the leading consulting and tool vending
organizations
– Adaptive, Ltd., Capgemini, EDS, Fujitsu, Fundacion European Software Institute, H-P,
IBM, MEGA International, Model Driven Solutions, Rhysome, and Softeam are the
submitters
– There also are 15 “supporters”
– IBM probably has contributed most heavily to the specification – thank you, Jim
Amsden – our representative to the SoaML specification committee
 Being adopted by the OMG’s UPDM committee as their standard for
services modeling

Sample SoaML noise
 I have been receiving customer inquiries for over a year – “Does RSA
support SoaML”?
– It’s nice that we can now say “yes”!
 SoaML site with statements of tool vendor support:
– http://www.omgwiki.org/SoaML/doku.php
– IBM leads the pack, naturally .

SoaML implementations
 SoaML is specified in two ways:
– UML profile
– SoaML metamodel
 We implement SoaML in Rational Software Architect as a UML-based
domain-specific language (DSL)

SoaML metamodel (1)
 The SoaML specification team has worked diligently to create as small a
metamodel as they could
 Wherever possible, metamodel elements have been defined to be able
to address multiple concepts
 Examples of the above:
– “Participant” is unifying concept for service provider component and service consumer
component
– ServicesArchitecture is a concept for describing both:
• Collaborations of participants to achieve a purpose, such as realize a business process
• Collaborations of service participants and non-service components to realize the
implementation of service operations

SoaML metamodel (2)
 Metamodel has been developed by committee, so there are some disunities and redundancies
– For example, meta-model supports both interface-centric and contract-centric styles of
service specification
– So, two ways to describe protocol contracts which govern how consumers and
providers of a given service must interact
• ServiceContract metamodel element – stereotyped UML Collaboration
 Main element used in contract-centric service specification
• OwnedBehavior of a ServiceInterface
 Subsidiary construct in interface-centric specification

SoaML metamodel (3)
 As of Beta 1 specification of April 1, 2009, with additions/changes from
Ballots 2 and 3
Removed; redundant with
ServicesArchitecture
Integration with OMG’s Business
Motivation Modeling profile
Behavioral Contracts
Added in Ballot 2 to support contract-centric
service specification – to be applied to
elements that are the types of ServiceContract
roles

SoaML metamodel (4)
 As of Beta 1 specification of April 1, 2009, with additions/changes from
Ballots 2 and 3
Changed to
“Request” in
Ballot 3
Changed to
“Service” in

SoaML metamodel (7)
 Rational Software Architect, SoaML profile supports the Beta 1
metamodel, plus the Consumer and Provider stereotypes from Ballot 2
 Rational SOMA 2.9’s content addresses the Services, Behavioral
Contracts, Service Data, and Capabilities portions of the Beta 1
metamodel
 Both RSA and Rational SOMA are interface-centric in their approach to
service specification.
– Because of this, Rational SOMA’s non-discussion of the Consumer and Provider stereotypes,
which are used in contract-centric service specification, is not critical

Key SoaML abstractions
 In our approach to service solution specification, the following SoaML
elements see heavy use
– Capability: used to represent candidate services
– Expose: documents which ServiceInterfaces expose which Capabilities
– ServiceInterface: central element for specifying service
– Participant: defines components that provision services
– ServicePoint: defines an interaction point by which a Participant offers a service
– RequestPoint: defines an interaction point by which a Participant requests a service
– ServiceContract: documents the protocol that generic providers and consumers must
use when interacting around a service
– ServicesArchitecture: documents the contract that governs how multiple Participants
work together by providing and using services expressed a service contracts

Sample Usage Patterns
 ServiceInterfaces exposing Capabilities
– See Example: Capability in Rational SOMA 2.9
 ServiceInterface specification
– See Example: ServiceInterface in Rational SOMA 2.9
 Participant specification
– See Example: Participant in Rational SOMA 2.9
 ServiceContract definition
– See Example: ServiceContract in Rational SOMA 2.9
 ServicesArchitecture description
– See Example: ServicesArchitecture in Rational SOMA 2.9
– See Concept: Service Composition and Choreography in Rational SOMA 2.9
 Most of the above examples are extracted from the Sample Service
Design model that is provided in RSA and in Rational SOMA 2.9
