Often, eGovernment services needed by citizens are composite in nature, where component services are offered by distributed and autonomous government agencies. Our approach to deliver the interagency eGovernment composite services for coordination, cooperation and seamless flow and sharing of data is accomplished through an eGovernment portal system based on a workflow management system (WFMS). Versatile eGovernment service delivery can be achieved through customization of the eGovernment services at the design stage, as well as through run-time adaptation of the services by reacting to changes in the government regulations and mandates, citizens' needs, or unexpected results during service execution. In this paper, we present an approach where the workflows adopt to run-time changes. Given a change condition, our system automatically identifies migration rules that specify operations and tasks needed to achieve run-time adaptation and to generate a new workflow. The migration rules are generated from the regulatory rules ontology, which ensure that the new workflow is in some sense consistent with the original workflow.
