Towards Development of QoS Based Data and Service Oriented Mashup Platform

Mashup is a new application development approach that allows users to aggregate multiple services to create a service for a new purpose. Data and service mashup technology is getting more attention in both enterprise and academia for building new end users applications fast in the complex and heterogeneous network environment in relatively short periods of time with little or no additional costs to cover IT resources. Even if the Mashup approach opens new and broader opportunities for data/service consumers, the development process still requires the users to know not only how to write code using programming languages, but also how to select and use the different Web APIs from different services. Our architecture supports dynamic discovery of various APIs and performs interactive and sequential result refinement to improve the quality of the presented result. We proposed a script-based definition of mashups which facilitates the development as well as the dynamic execution of mashups. This architecture is realized using the QoS based Data and Service Mashup System (QDSMS), a novel platform to support end users to create, reuse and manage mashups based on mashup script based definition. We describe the overall design of QDSMS and discuss its main enabling technologies. This platform will improve the efficiency of mashup development and optimal use of storage and computing power of the network and server elements.
