Hera is a model-driven methodology for designing Web information systems. In the past a CASE tool for the Hera methodology was implemented. This software had different components that together form one centralized application. In this paper, we present a distributed Web service-oriented architecture for the Hera software in which components are mapped to Web services. The present CASE tool is based on two Web services: a data service which maps to the data component and a presentation service which maps to the presentation component. For these two Web services a detailed description of their interfaces in WSDL is given as well as examples of SOAP messages exchanged between these services and a client. The paper also proposes how to extend the present architecture in order to include other services like an adaptation service for performing presentation adaptation based on a user profile and a profile service as a shared memory service for user profiles.
