One of the fundamental attributes of modern government service delivery mechanism is the ability to offer a citizen-centric view of the government model. Life-event model is the most widely adopted paradigm supporting the idea of composing a single complex service that corresponds to an event in a citizen's life. Elementary building blocks of Life-event are based on atomic services offered from multiple government agencies. Composite services are desirable mainly because of their added value to businesses and government agencies. This study found that the methodological mechanics of service integration, and in particular, the requirements engineering for services integration has been overlooked. It introduces a multilevel modelling framework for analysis and design of Life-event within the government service integration context based on the principle of abstraction. It also proposes a top down multilevel abstraction approach to model Life-event candidates and elicit their requirements and specification. This study explains the problem space of e-government service delivery integration, and stresses the ontology analysis and modelling as one of the essential requirements for modelling Life-events.
