JavaScript has empowered users of Web applications. Using tools like Greasemonkey they can customize the application according to their specific needs through the injection of user scripts. The implementation approach, however, usually involves either extensions in the browser or client side proxies which go against the very nature of a Web application. The reason is that the customized application is not available in an ubiquitous manner anymore since the user needs to install and configure a piece of software in every place where he plans to use the application. We propose a software architecture that uses existing standards to store and fetch the needed information to support client side customization in a way that the modified application is still available from any browser and any computer as it was the original one. This paper describes the proposed architecture and a prototype implementation as a proof of concept. A variety of user scripts were successfully tested on the prototype. Once properly configured, the customized application was accessed from different machines using different standard versions of the browsers. The customized application remains thus universally accessible and we do not need to loose this crucial advantage.

The poor locality of operation descriptions expressed in the Web Service Description Language (WSDL) makes them difficult to analyze and compare in web service discovery tasks. This problem has led us to develop a new method for service operation comparison involving contextualizing operation descriptions by inlining related type information from other sections of the service description. In this paper, we show that this contextualization of web service descriptions can enable topic models (statistical techniques for identifying relationships) to produce semantically meaningful results that can be used to reverse engineer service-oriented web systems and automatically identify related web service operations. Specifically, we model contextualized WSDL service operations using Latent Dirichlet Allocation, and show how this approach can be used to more accurately find similar web service operations.

The first part of the title (after “Keynote:”) is the title of a paper and talk presented by the speaker at WSE 2001 [1], ten years ago in Florence, Italy. The abstract for the 2001 paper was: The current textual and graphical interfaces to computing, including the Web, is a dream come true for the hearing impaired. However, improved technology for voice and audio interface threaten to end this dream. Requirements are identified for continued access to computing for the hearing impaired. Consideration is given also to improving access to the sight impaired.

3D visual interfaces are effective, attractive, and are considered as a key factor to add value to various software applications improving the overall user experience. The Web is one of the domains where 3D visual interfaces can bring advantages, and the recent integration between 3D and web technologies, driven by html 5 and WebGL, establishes good basis to extend web applications with 3D features. However, much work must be done to promote html 5 and WebGL from the role of enabling technology to the role of solid foundation for enterprice level applications. In this scenario the focus of the paper is on outlining some guidelines and a workflow to add 3D data visualization features to existing Web applications. The paper also discusses the main results we achieved applying these guidelines to two different application fields.

This paper presents an approach for the model-driven fast prototyping of Web applications. The approach exploits well known Model-Driven Engineering frameworks and technologies, such as Eclipse EMF, GMF, and Xpand, to enable the design of a Web application and the automatic generation of the code artifacts implementing a ready to deploy prototype of it. The approach allows to effortlessly and quickly carry out a modeling-generation-validation process in order to validate and refining the design of a Web application before actually implementing it. The paper describes the approach and the process followed to define it, the supporting tools and the technologies used to develop them, and the results from a case study of designing and generating the prototype of a Web application for on-line note taking and sharing. The process and the technologies used to develop the proposed approach can be reused to develop a fast prototyping approach for a different design model and a different target technology platform.

Rich Internet Applications (RIAs) can be used as a way to modernize Legacy Applications (LAs), in particular to provide users with an innovative, state-of-the-art interactive experience. RIAs have the same richness in term of interaction grammar as Client-Server Applications (CSAs) and Desktop Applications (DAs), giving designers the opportunity to exploit the Web infrastructure also in domains where the communication between the user and the application is more complex of a sequence of page requests. In the transition from LAs to RIAs, however, several challenges need to be faced, including fundamental issues affecting user requirements and usability. In this paper we present the preliminary results of a large-scale industrial project, which focused on migrating a complex LA (VB6 + Cobol) to a RIA (JSF + SOA). In this context, we introduce a novel method (Rich-IDM) to transform the design of the User Experience (UX) and the strategy for interactive communication from LAs to RIAs in a graceful and disciplined manner, thus preventing the many flaws that typically are manifested in similar projects. We also show how Rich-IDM originally extends and well integrates into other well-known conceptual tools — the Conallen's UX model and the RUX model — within the OMG's ADM framework.

The model of computation in which software is downloaded and/or run dynamically from the network is commonly referred to as cloud computing. Historically, cloud computing has implied the use of thin clients, i.e., an approach in which the majority of computation is performed on the server side. However, in recent years the landscape of cloud computing has become quite diverse. This is partly because client computers and devices in cloud-based systems have become richer and far more powerful, and partly because the capabilities of the web browser as an application platform have increased substantially. In fact, with the upcoming HTML5 and WebGL standards, we anticipate client computers and devices to take a much more encompassing role in cloud computing. Additionally, the rapidly increasing use of mobile devices will have a dramatic impact on the use of cloud-based systems. In this paper we analyze the different flavors of cloud computing, with an attempt to classify web-based computing systems and to facilitate discussion and reasoning about such systems in general.

Service Oriented Architecture, which builds on distributed computing platforms, is increasingly being adopted by organizations in both public and private sectors. Migration from traditional monolithic systems to services, in particular web services, characterizes much of systems evolution today. This paper analyzes some of the performance and modularization problems involved in current service-oriented computing. It investigates under which circumstances the communication between service providers and service consumers can be made more efficient by eliminating certain steps from traditional Remote Procedure Call (RPC) methods. After discussing traditional service invocation and its drawbacks, this paper proposes an alternative approach called Distributed Service Delegates (DSD). DSD is based on emphasizing client-side or local computations. An experiment is designed and implemented to measure the trade offs between traditional methods, in this case Web services, and the proposed DSD. The results of this experiment are discussed and its implications for future research are indicated.

Services Oriented Architecture (SOA) is becoming a popular style for building complex systems-of-systems that allow businesses to work together across organizational boundaries. However concerns have been raised about the comprehensibility and maintainability of SOA composite applications. Integrating and deploying SOA applications requires artifacts in a variety of web-based languages (WSDL, XSD, BPEL, etc.) often produced by code-generation tools. It becomes difficult for a human to discover and understand the dependencies between these artifacts in an existing system. In this paper, we describe ongoing research on using search techniques to facilitate SOA maintenance by allowing users to query collections of artifacts making up a SOA composite application. The main focus in this paper is a case study using our prototype search tool SOAMiner to identify a set of abstractions that extract useful and critical information for maintainers, thereby bridging the heterogeneity of SOA artifacts while opportunistically exploiting their structure. Results of the study indicate that the highest priority abstractions for SOA are datatype summaries, service invocation (calling) relationships, and data usage relationships.
