Demand-Driven MashUp Framework with AJAX Widget Viewer

Abstract

Many Web applications provide information in table formats that are useful for data comparison (e.g. comparison of hotel plans for hotel search applications). Using mashup technologies, one can add niche criterion to meet various user's requests, but large number of columns will decrease the visibility of the table and may incur many needless requests to Web services. Interactive selection of columns and filtering facilities may be helpful, but the implementation of these facilities on bare AJAX framework will require careful treatments of asynchronous requests. This paper presents a framework for Web application development that provides easy creation of mashups and AJAX widgets for data browsing. One can create mashups only by preparing configure file to attain mashup data model that works in demand-driven manners for interactive access via widgets.
