Linking IT architecture to IT services
Components implement the service interfaces providing the link to systems.

Ports on the participating components provide and require the service interfaces for each service provided or used May 2009
Definition of service in SoaML
A service is value delivered to another through a welldefined interface and available to a community (which may be the general public). A service results in work provided to one by another. Service Oriented Architecture (SOA) is a way of describing and understanding organizations, communities and systems to maximize agility, scale and interoperability. SOA, then, is an architectural paradigm for defining how people, organizations and systems provide and use services to achieve results. SoaML provides a standard way to architect and model SOA solutions using the Unified Modeling Language (UML).
SoaML Goals
Intuitive and complete support for modeling 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 modeling Design by contract or dynamic adaptation of services To specify and relate the service capability and its contract No changes to UML
SoaML Scope
Extensions to UML2.1 to support the following new modeling 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.
SoaML focuses on the basic service modelling concepts SoaML is NOT a methodology
A foundation for further extensions both related to integration with other OMG metamodels like BPMN 2.0, SBVR, OSM, ODM and others.
SoaML Overview
SoaML metamodel and UML Profile Service capabilities Services, services contracts and service specifications Service data Services Architecture Service Classification Unifying collaboration modeling and composite structures Milestones Integration with other submissions
BMM Integration
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 Message Type data exchanged between services
The SoaML Profile
SoaML is defined as a small set of UML stereotypes. These specialize a UML tool for use with SoaML. Standard UML can be used as well, as part of a SoaML model. Some tools provide enhanced SoaML support.
