Modelling electronic service systems usingUML

This paper presents a profile for modelling systems of electronic 
services using UML. Electronic services encapsulate business services, 
an organisational unit focused on delivering benefit to a consumer, 
to enhance communication, coordination and information management. 
Our profile is based on a formal, workflow-oriented description of electronic 
services that is abstracted from particular implementation technologies. 
Resulting models provide the basis for a formal analysis to verify 
behavioural properties of services. The models can also relate services to 
management components, including workflow managers and Electronic 
Service Management Systems (ESMSs), a novel concept drawn from experience 
of HP Service Composer and DySCo (Dynamic Service Composer), 
providing the starting point for integration and implementation 
tasks. Their UML basis and platform-independent nature is consistent 
with a Model-Driven Architecture (MDA) development strategy, appropriate 
to the challenge of developing electronic service systems using 
heterogeneous technology, and incorporating legacy systems.
