Integrating heterogeneous user interfaces in service oriented web applications

Abstract

Translate Article

Service Oriented Architecture (SOA) is a design framework that permits the developer to build complex applications from smaller modules called services. When applying SOA to web applications, developers face several challenges. Among others, the heterogeneous user interfaces provided by these services must be adapted to fit into the larger application.This paper discusses approaches to automated adaptation of web application's layout and design. We review the range of web-based user interface modifications, suggest a technique that allows us the automated execution of the described steps and finally explore transparent integration of the modified user interfaces into a given web page flow (using a proxy server). Our approach relies on the proposed meta-language UDLD, which permits application providers to equip their user interfaces with semantic information about included components.
