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
