“…b) Context model updating: It is necessary to update the context model at the data level. c) Context model monitoring: Two methods are proposed: In [5], monitoring is achieved by periodically refreshing the pages at any user's request; whereas in [6], a monitoring module is introduced which refreshes the pages when context variation triggers the adaptive action. In addition, Extended WebML prescribes a run-time algorithm that supports automatic execution of adaptive actions; the page computation algorithm of WebML is still used for non-adaptive actions.…”

Due to the rapid expansion of web applications, the information and services provided on the web have proliferated, leading to ever-increasing complexity. This has not only resulted in the utmost significance of information quality and accuracy on the web, but has also necessitated that access to information be improved. Hence, adaptive web systems have emerged, which focus on adapting web content, presentation, and navigation to meet the needs of the users according to their individual circumstances and preferences. In this field, focus has gradually shifted from creation of new adaptive techniques to solving the problems of analysis and design of adaptive applications; in other words, it has become important to handle the dynamism of the runtime environment and the complexity involved in developing these applications. Model-Driven Engineering (MDE) is considered a promising approach for overcoming these problems, mainly due to its modeling features: Models are created at different levels of abstraction (thus enhancing complexity management), and the process can potentially be automated through the use of transformation rules. We provide a review of several prominent methodologies that utilize MDE for developing adaptive web applications, and propose a criteria-based evaluation approach that highlights their strengths and weaknesses. Evaluation results can be used for comparing and selecting methodologies for use in web development projects; they can also be used for constructing a new methodology that exploits the strengths and addresses the shortcomings of existing methodologies.

“…The standard HTTP protocol underlying Web applications implements a strict pull paradigm. Therefore, such capabilities can be achieved by periodically refreshing the viewed page and granting the adaptive logic of the application the possibility to intervene on the application itself Figure 5 Conventional pages and C-pages in an adaptive hypertext [19]. before rendering the actual response.…”

“…before rendering the actual response. Polling mechanisms, such as the HTML http-equiv META-option, or also JavaScript, JavaApplets, or Flash scripts, provide a valuable "simulation" of the required active behavior [19]. On one hand they trigger the adaptability actions attached to the page, as required by context model changes; on the other hand, they enable the communication of client-side sensed context data to the application server.…”

The UM-MAIS Methodology for Multi-channel Adaptive Web Information Systems

et al. 2007

Multichannel Adaptive Web Information Systems (WISs) are emerging as a new class of information systems, characterized by their powerful use of mobility and contextawareness. Different methodologies have been proposed so far for the analysis and design of Multichannel Adaptive WISs, specifically focused on the front-end layer or the back-end layer, but no methodology has aimed to cover all the lifecycle and to design all the components that characterize Multichannel Adaptive WIS. This paper fills such a gap, by presenting UM-MAIS (Unified Methodology for Multichannel Adaptive Information Systems), a new methodology that capitalizes on well-established existing methods. It supports the analysis and design of the various components of Multichannel Adaptive WISs (including the user's experience) in a comprehensive and unified manner with special emphasis on context modeling, personalization, and adaptation.

“…For instance, the Navigational design step is now performed after the WebML has evolved continuously to satisfy some of these new challenges. As a result of this evolution, WebML has been extended to address the generation of: web service-enabled (Brambilla et al, 2006b), workflow-based (Brambilla et al, 2006), context-aware (Ceri et al, 2007), semantic web (Brambilla et al, 2006a) and rich internet (Bozzon et al, 2006) applications. A complete description of this method gathering all these extensions is presented in (Brambilla et al, 2008 However, none of the previously four presented original models were aimed at the development of workflow-based applications.…”

The proposed method provides mechanisms that allow specifying the particular characteristics of BP-driven Web applications at the modelling level (in a technological independent manner). In addition, based on the Model Driven Engineering, application specifications are combined and transformed to obtain different software artefact. On the one hand, by means of model-to-model transformations, we combine model specifications to obtain different models. On the other hand, by means of model-to-text transformations, models can be derived into executable code implemented in a particular technology. In addition, based on the reference model proposed for Workflow Management Systems, the method proposes the extension of the logical layer of the generated Web applications with the introduction of process engine.The method proposed in this thesis is supported by a tool called BIZZY. This tool has been developed in the Eclipse environment and covers the development process from modelling to code generation. Specifically, the generated code corresponds to the Tapestry Web framework (framework for Java Web applications) and the WS-BPEL language, which allows the execution of the BP defined at the modelling level. ResumenActualmente, la World Wide Web se ha convertido en la plataforma más común para llevar a cabo el desarrollo de aplicaciones corporativas. Estas aplicaciones reciben el nombre de aplicaciones Web y entre otras funciones, deben de dar soporte a los Procesos de Negocio (PN) definidos por las corporaciones.Esta tesis presenta un método de Ingeniería Web que permite el modelado y la construcción sistemática de aplicaciones Web que soportan la ejecución de PN. En este trabajo se conciben los PN desde un punto de vista más amplio que el abordado por otros métodos de Ingeniería Web. El tipo de PN abordados incluye tanto procesos cortos como largos. A grosso modo, esta concepción más amplia permite considerar procesos que involucran diferentes participantes (personas y/o sistemas) los cuales cooperan para llevar a cabo un objetivo particular.Además, dependiendo del tipo de proceso que se esté ejecutando (corto o largo), la interacción del usuario con el sistema deberá adaptarse a cada caso.El método presentado en esta tesis ha sido desarrollado basándose en el Desarrollo de Software Dirigido por Modelos.De esta forma, el método propone un conjunto de modelos que permiten representar los diferentes aspectos que caracterizan las aplicaciones Web que soportan la ejecución de PN. Una vez el sistema ha sido representado en los modelos correspondientes, mediante la aplicación de transformación de modelos se obtiene otros modelos (transformaciones de modeloa-modelo) e incluso el código que representa el sistema modelado en términos de un lenguaje de implementación (transformaciones de modelo-a-texto).El método propuesto en esta tesis está soportado por una herramienta llamada BIZZY. Esta herramienta ha sido desarrollada en el entorno de Eclipse y cubre el proceso de desarrollo desde la fase de modelado hasta la generación de ...
