Adoption Of Web Services Research Articles

Infrastructure for e-government Web services

In efforts to use information and communication technologies for the civil and political conduct of government, many countries have begun supporting e-government initiatives. The ultimate goal is to improve government-citizen interactions through an infrastructure built around the "life experience" of citizens. To facilitate the use of welfare applications and expeditiously satisfy citizens' needs, we wrapped these applications in modular Web services. Adopting Web services in e-government enables government agencies to provide value-added services by defining a new service that outsources from other e-government services; to uniformly handle privacy issues: and to standardize the description, discovery, and invocation of social programs. The core of our research is to develop techniques to efficiently access e-government services while preserving citizens' privacy. To that end we designed and implemented an infrastructure called Web Digital Government.

Developing XML Web services with WebSphere Studio Application Developer

Web services have recently emerged as a powerful technology for integrating heterogeneous applications over the Internet. The widespread adoption of Web services promises to usher in an exciting new generation of advanced distributed applications. These will support a new and growing set of specifications, such as Simple Object Access Protocol (SOAP), Web Services Description Language (WSDL), and Universal Description, Discovery, and Integration (UDDI). Extensible Markup Language (XML) and its associated family of standards also play a central role in Web services by providing a data interchange format that is independent of both programming languages and operating systems. The application developer seeking to reap the benefits of Web services is therefore faced with a significant, and potentially steep, new learning curve. Clearly, application development tools that lower this barrier are crucial for the rapid and widespread adoption of Web services. This paper discusses the development tasks associated with XML Web services and describes a new suite of tools that improve developer productivity, by reducing the requirements for detailed knowledge of the underlying specifications and standards, and allow the developer to focus on the business problem domain. This suite of XML and Web services tools is part of IBM's recently released WebSphere® Studio Application Developer product, which is based on the new Eclipse open source tool integration platform.
