The availability of domain frameworks to enable rapid
development of Electronic Public Services (EPS) is essential to meet
the increasing demand for mature EPS by various government
stakeholders. This paper presents a composite domain framework
comprising frameworks to build the Front-Office and Back-Office parts
of an EPS. The framework supports a set of domain requirements
obtained through a detailed analysis of over 30 concrete public
services. After presenting these requirements, the framework is
described in four stages - architecture, design, implementation and
instantiation - all using UML to capture the artifacts built during
development. We also illustrate the application of the framework
through a case study in developing an Electronic Licensing Service by
means of framework instantiation. We conclude with some comments on
the complexity, flexibility and performance of the framework. This
work was carried out as part of the e-Macao Project to build a
foundation for e-Government in Macao, funded by the Government of
Macao SAR.
