Metamodeling or profiling: a practical case in the web engineering domain

Model Driven Development (MDD) provides several choices for the definition of modeling languages. The definition of a complete metamodel and the customization of a given metamodel using profiles are common approaches. In our opinion neither of these approaches is better than the other, and the choice should depend on the characteristics of each project. This paper describes our experiences defining a graphical notation for the characterization of web navigational maps based on a MOF metamodel and a UML profile. The advantages and drawbacks of both approaches are examined, as well as the solution selected for our project.Presentado en el VIII Workshop Ingeniería de Software (WIS)Red de Universidades con Carreras en Informática (RedUNCI

Techniques and Tools for Web Requirements in NDT, UWE and WebML

Requirements Engineering (RE) is one of the serious issues for software construction. In the scientific literature we can find several reasons of this affirmation, is spite of this, most of the development process of new software crash due to wrong requirements phase. Several proposals exist for requirements modelling, analysis and elicitation in Software Engineering (SE), however the current market is focusing on the development of Web and mobile applications, specially using Model-Driven methods, this is the reason why we consider it necessary to know the techniques and tools for requirements modelling, analysis and elicitation applied in Model-Driven Web Engineering in order to know their gaps and current trends to propose new solutions. To do this, the most important methods were selected outside the academic area such as NDT, UWE and WebML. A total of 63 publications from ACM, IEEE, Science Direct, DBLP and World Wide Web had been reviewed

A Metamodel Proposal for a Web Development Code Generation Tool

Code generation is an important part of Model-Driven Development as well as the abstract representation of the software functionality. One of the strong deficiencies in this paradigm is the lack of research projects regarding to code generation that uses the terminology applied in the industry. In order to ameliorate this scenario, in this work is presented a metamodel proposal for a Web development code generation tool. This proposal is based on the terminology used in the industry for Web development in the region of Sinaloa, México. This is an extension and updated explanation of our work previously presented in a conference

Adaptive model for web engineering methods to develop multi web applications in agile environment

Model Driven Web Engineering (MDWE) is an application of a model driven paradigm in the domain of web software development. MDWE is helpful because technologies and platforms of web applications constantly evolve into Web Engineering Methods (WEMs). The evolution of web applications has consequently introduced new features and challenges, therefore existing WEMs need to be improved. These WEMs have failed to develop modern web applications’ features. Furthermore, no single WEM is capable of covering the whole lifecycle phases. These issues decrease the usability. In addition, the Interaction Flow Modeling Language (IFML) as a recent method has also not been able to address them. This thesis developed a new WEM, Useable Adaptive Agile IFML (UAA-IFML) to solve these issues in several steps. In this research, mixed methods used were qualitative and quantitative methodologies. In the first step, a new adaptive model was defined for supporting the features of multi-web applications. The new model was developed via an adaptive model into the IFML metamodels known as Adaptive IFML (AIFML). In the second step, IFML was enriched through MockupDD for covering lifecycle, known as Agile IFML (A-IFML). This is because MockupDD provides an agile environment, hence agile lifecycle can solve the lifecycle issue. In the third step, a new adaptive model and agile process were combined as Adaptive Agile IFML (AAIFML). This integration increased the usability of the IFML method. In presenting the usability of AA-IFML, experimentation of the framework was extended to evaluate the usability of WEMs. Besides, feedbacks on the usability of AA-IFML were obtained from developers around the world using three instruments, namely performing tasks, answering questionnaires, and interviewing experts. Analysis on the feedback indicated a 20% improvement usability of the AA-IFML compared with current IFML. The findings have shown that the UAA-IFML is beneficial for developers, as they would only need to use one method to design modern web application features in the whole lifecycle phases

Goal-driven requirements analysis for hypermedia-intensive Web applications

Requirements analysis for Web applications still needs to employ effective RE practices to accommodate some distinctive aspects: capturing high-level communication goals, considering several user profiles, defining hypermedia-specific requirements, bridging the gap between requirements and Web design, and reusing requirements for an effective usability evaluation. Techniques should be usable, informal, require little training effort, and show relative advantage to project managers. On the basis of the i * framework, this paper presents a proposal for defining hypermedia requirements (concerning aspects such as content, interaction, navigation, and presentation) for Web applications. The model adopts a goal-driven approach coupled with scenario-based techniques, introduces a hypermedia requirement taxonomy to facilitate Web conceptual design, and paves the way for systematic usability evaluation. Particular attention is paid to the empirical validation of the model based on the perceived quality attributes theory. A case study developed with industrial partners is discusse

Estimating, planning and managing Agile Web development projects under a value-based perspective

Context: The processes of estimating, planning and managing are crucial for software development projects, since the results must be related to several business strategies. The broad expansion of the Internet and the global and interconnected economy make Web development projects be often characterized by expressions like delivering as soon as possible, reducing time to market and adapting to undefined requirements. In this kind of environment, traditional methodologies based on predictive techniques sometimes do not offer very satisfactory results. The rise of Agile methodologies and practices has provided some useful tools that, combined with Web Engineering techniques, can help to establish a framework to estimate, manage and plan Web development projects. Objective: This paper presents a proposal for estimating, planning and managing Web projects, by combining some existing Agile techniques with Web Engineering principles, presenting them as an unified framework which uses the business value to guide the delivery of features. Method: The proposal is analyzed by means of a case study, including a real-life project, in order to obtain relevant conclusions. Results: The results achieved after using the framework in a development project are presented, including interesting results on project planning and estimation, as well as on team productivity throughout the project. Conclusion: It is concluded that the framework can be useful in order to better manage Web-based projects, through a continuous value-based estimation and management process.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-

Exploiting Personal Web Servers for Mobile Context-Aware Applications

There is an increasing trend in moving desktop applications to web browsers, even when the web server is running on the same desktop machine. In this paper we go further in this direction and show how to combine a web server, a web application framework (enhanced to support desktop-like Model-View-Controller interaction) and a context-aware architecture to develop web based mobile context-aware applications. By using this approach we take advantage of the well established web paradigm to design the GUIs and the inherent ability of the web to mash up applications with external components (such as Google Maps). On top of that, since the web server runs on the device itself, the application can access local resources (such as disk space or sensing devices, which are indispensable for context-aware systems) avoiding the sandbox model of the web browsers. To illustrate our approach we show how a mobile hypermedia system has been built on top of our platform.Facultad de InformáticaLaboratorio de Investigación y Formación en Informática Avanzada (LIFIA
