SHAPE Solution Overview• Solution centred around
SoaML– Metamodel for describing
service-oriented landscapes• SoaML is extended with
metamodels for ShaML– Semantically-enabled
Heterogeneous Architecture Modelling Language
– other technology platforms– advanced service engineering
techniques• Tool support provides
– integrated tool suite that supports the modelling
– encompasses the necessary model transformations
– methodology framework that provides role-specific guided procedures

SoaML
• Service oriented architecture Modeling Language (SoaML)– Extensions to UML2.1 to support service concepts.– SoaML focuses on the basic service modelling concepts.– A foundation for further extensions both related to integration with other
OMG metamodels like BPMN 2.0, SBVR, OSM, ODM and others.• Website:
– http://www.soaml.org
• Capabilities:– identifying services– specifying services– defining service consumers and providers– policies for using and providing services.– defining classification schemes– defining service and service usage requirements and linking them to
related OMG metamodels, such as the BMM and BPMN 2.0.

BPMN to SoaML – Mapping Rules [0]
• Mapping Rule 0: Process to Services Architecture
• Mapping Rule 1: Task to UML Action• Mapping Rule 2: Sub-Process to
Services Architecture• Mapping Rule 3: Pool to Participant
(Community-level)• Mapping Rule 4: Lane to Participant
(Participant-level)• Mapping Rule 5: Message “Begin” to
Service • Mapping Rule 6: Message “End” to
Request• Mapping Rule 7: Process fragment
(pattern) to Service Contract
• The services architecture is aligned with the business process, and the participants and service contracts can be derived from the pools or lanes and activities in the business processes respectively.

Mapping Rules [1-2]
• Mapping Rule 1: Task to UML Actions
• BPMN: task providing a useful output for the participants
• SoaML: abstract interface for the job
• Mapping Rule 2: Sub-Process to Services Architecture
• BPMN: more complex process than a simple task
• SoaML: details the roles and tasks of the sub-process

Mapping Rules [3-4]
• Mapping Rule 3: Pool to Participant (Community-level)
• BPMN: a business entity or a participant of a process
• SoaML: role in a community-level services architecture
• Mapping Rule 4: Lane to Participant (Participant-level)
• BPMN: a participant or a department hierarchy
• SoaML: role in a participant-level services architecture

Mapping Rules [5-6]
• Mapping Rule 5: Message “Begin” to Service
• BPMN: starting end of the data channel between two participants
• SoaML: services provision for other participants
• Mapping Rule 6: Message “End” to Request
• BPMN: other end of the communication channel
• SoaML: reflexion of the data channel target in the service consumption

Mapping Rules [7]
• Mapping Rule 7: Process fragment (pattern) to Service Contract
• BPMN: identification of process fragments providing and consuming services
• SoaML: service specification for definition of roles of each participant

Conclusions and Future Work
• Conclusions– overview of the SoaML modelling language– application for describing both a business and IT perspective
on SOA– set of model transformation rules for mapping BPMN onto
SoaML– testing in industrial use cases in the SHAPE project with the
objective of aligning business and IT models• Future Work
– identification and description of additional patterns and guidelines for mapping to service contracts
– mapping rules definition update and alignment with the ongoing SoaML and BPMN 2.0 specification
– provision of better tool support for multi-tier service contracts– investigation of a bottom-up approach for transformations
