Designing An Ajax-Based Web Application Restfully

The development of an AJAX-based web application involves several challenges as the webpage is updated by using the AJAX calls without reloading the entire page as in any traditional webpage. This prevents one from going back to the previous view of the page as the browser does not reload the entire page; instead it only updates the page. My hypothesis is that if an AJAX-based application is designed by using the software architecture style called the Representational State Transfer (REST), then it is possible to overcome these challenges, which cannot be handled by using web-services. In order to investigate this, the Material Properties Repository, an AJAX-based application was redesigned by using REST. The results support my initial hypothesis. In this process of designing MPR using REST, a generalized software engineering process was created for designing an AJAX-based application RESTfully

A RESTful Approach to the OGSA Basic Execution Service Specification

Abstract—The OGSA–Basic Execution Service (BES) specification has recently been proposed by the Open Grid Forum (OGF) as the standard job submission and management interface across different Grid middlewares. This specification defines a Web Service interface in terms of a Web Services Description Language (WSDL) document for creating, monitoring and managing computational jobs (called activities), and for querying the capabilities of the BES service itself. In this paper, we propose an alternate incarnation of the BES functionalities according to the Representational State Transfer (REST) architectural style. We describe the mapping of the BES operations in terms of HTTP actions on resources. We compare the REST formulation of BES with the standard WS-based one. We show that all BES operations can be expressed in a very natural way using the standard HTTP protocol and following the REST approach; moreover, we present useful extensions that are expected to appear in the near future.
