Marmite: Towards End-User Programming for the Web

Abstract-The need for integration of all types of client and server applications that were not initially designed to interoperate is gaining popularity. One of the reasons for this popularity is the capability to quickly reconfigure a composite application for a task at hand, both by changing the set of components and the way they are interconnected. Service-Oriented Architecture (SOA) has recently become a popular platform in the IT industry for building such composite applications with the integrated components being provided as Web services. A key limitation of solely Web-service-based integration is that it requires extra programming efforts when integrating non-Web service components, which is not cost-effective. Moreover, with the emergence of new standards, such as Open Service Gateway Initiative (OSGi), the components used in composite applications have grown to include more than just Web services. Our work enables progressive composition of non-Web-service-based components such as portlets, Web applications, native widgets, legacy systems, and Java Beans. Further, we proposed a novel application of semantic annotation together with the standard semantic Web matching algorithm for finding sets of functionally equivalent components out of a large set of available non-Web-service-based components. Once such a set is identified, the user can drag and drop the most suitable component into an Eclipse-based composition canvas. After a set of components has been selected in such a way, they can be connected by data-flow arcs, thus forming an integrated, composite application without any low-level programming and integration efforts. We implemented and conducted extensive experimental study on the above progressive composition framework on IBM's Lotus Expeditor, an extension of an SOA platform called the Eclipse Rich Client Platform (RCP) that complies with the OSGi standard.

“…Therefore, a mashup strategy becomes more implementable and as a result, has been used in many information integration-lite tasks (Franklin, Halevy et al 2005;. Examples include Google maps (Wong and Hong 2007) and Avian Flu maps (Butler 2006). However, the openness of the mashup fabric along with its integration lite nature limits its application as the first layer technology option for personalized biomedical data integration.…”

In this paper we discuss the design space of methods for integrating information from Web services into websites. We focus primarily on client-side mash-ups, in which code running in the user's browser contacts Web services directly without the assistance of an intermediary server or proxy. To create such mash-ups, we advocate the use of "widgets," which are easy-to-use, customizable HTML elements whose use does not require programming knowledge. Although the techniques we discuss apply to any Web-based information system, we specifically consider how an OPAC can become both the target of Web services integration and also a Web service that provides information to be integrated elsewhere. We describe three widget libraries we have developed, which provide access to four Web services. These libraries have been deployed by us and others.Our contributions are twofold: We give practitioners an insight into the trade-offs surrounding the appropriate choice of mash-up model, and we present the specific designs and use examples of three concrete widget libraries librarians can directly use or adapt. All software described in this paper is available under the LGPL Open Source License. ■ ■ BackgroundWeb-based information systems use a client-server architecture in which the server sends HTML markup to the user's browser, which then renders this HTML and displays it to the user. Along with HTML markup, a server may send JavaScript code that executes in the user's browser. This JavaScript code can in turn contact the original server or additional servers and include information obtained from them into the rendered content while it is being displayed. This basic architecture allows for myriad possible design choices and combinations for mash-ups. Each design choice has implications to ease of use, customizability, programming requirements, hosting requirements, scalability, latency, and availability. server-side mash-upsIn a server-side mash-up design, shown in figure 1, the mash-up server contacts the base server and each source when it receives a request from a client. It combines the information received from the base server and the sources and sends the combined HTML to the client.Server-side mash-up systems that combine base and mash-up servers are also referred to as data mash-up systems. Such data mash-up systems typically provide a Web-based configuration front-end that allows users to select data sources, specify the manner in which they are combined, and to create a layout for the entire mash-up.
