Considering navigation as one of the emergent features of web applications, it is necessary to treat it in an adequate way providing the mechanisms to allow for reusing navigational specifications. This paper presents an 00 approach to capture properly the navigational semantics in order to use the navigational specialization as a tool for extending and reusing navigation characteristics and requirements.

CVN handles both academic and administrative tasks. It also provides statistics of usage, over standard periods of time, with the help of a graphical representation tool. The objective is to model the behavior of the agents in the virtual e-learning environment and use the statistics and tool to help to optimize the contents of the campus. The data collected would also allow to plot the path the users follow in the campus pages (called navigation graph). Although further research is needed we believe that the metrics can be correlated with the academic performance of students.

In such a context, there is a significant demand for Web applications. From the Software Engineering point of view, Web-based applications have specific characteristics that must be handled in the development process. For this reason, it is necessary to do some adjustments in existing software development processes in order to give a better support for the development of these applications. Aiming the solution of this problem, this tutorial presents a proposal for extending the Rational Unified Process (RUP) in order to produce a better Analysis and Design Model for this kind of applications.

This process of user requirements elicitation must generate a Conceptual Schema where all these aspects -including navigation and presentation- must be properly captured. As a consequence, a Conceptual Schema for a Web Application must include in its expressiveness new conceptual primitives specifically designed to specify web characteristics that are no present in the conventional conceptual modelling approaches. These conceptual patterns will be introduced in this tutorial. Furthermore, how to use them in a modern software production process will be shown, using well-known, widely-used notations as UML - properly extended for specification of Web Applications -, and applying the ideas to a practical case of study. Finally, how to guide the process of converting the conceptual patterns into their corresponding final software representations will be analysed, to show how to go from the problem space to the solution space in a way as automated as possible.

In recent years, Web-based teaching and learning sites and applications (also called e-learning sites and applications) have exponentially started to grow, being a central phenomenon for the industry and education fields. Key factors for the present and future success of these applications and organizations are, on one hand, the fulfillment of technological standards for learning environments (e.g., IEEE, IMS, ISO standards, among others), and, on the other hand, the utilization of well-defined development processes and the production of required quality. One of our current concerns is the assessment of the quality of e-learning sites and applications. In this paper a taxonomy of Web-based Instructional Systems (WbIS), and ultimately the quality requirements for the Functionality characteristic are thoroughly described, regarding an intentional audience. An evaluation case study for this domain, using the WebQEM (Quality Evaluation Methodology) strategy is currently being run.

Registered users can play in two different types of single games, in one of them the system allows the player to select the topic of the question. There is also a group game option which deals with several topics. The way in which the system treats each player depends on his level, which is dinamically assigned to him according to his scores. There are also many other posibilities such as record management, rankings, single games management (saving, continuing and deleting games) implemented in the system.

In this paper, we propose and evaluate a model of defining and distributing priorities among the different Web connections, using the JVM (Java Virtual Machine). We propose a QoS hybrid method with specific priorities distribution policy by overcoming the limitations of IP address and requested content type methods. It is shown that is possible obtain some benefits by providing a relative notion of QoS for a web-based service with JVM and without modifications within Kernel structures of the operating system. The QoS hybrid method can also be used to prevent Deny of Service. Tue, 01 Jan 2002 00:00:00 GMT http://sedici.unlp.edu.ar:80/handle/10915/184175 2002-01-01T00:00:00Z Abstract.

Particularly, starting from a conceptual model for metrics, we thoroughly discuss a catalogue template for product metrics instantiating it with some Web metrics. A catalogue of metrics basically allows tools, evaluators and other stakeholders to have a service and a consultation mechanism, which starts from a sound specification of the entity type, the attribute definition and motivation, the metric formula, criteria, and application procedures, among other template items. The metrics repository and the cataloguing tool can be appropriately used to support different quality assurance processes such as non-functional requirements specification, quality testing definition, etc. in different phases of the software life cycle. Effective and full-fledged quality assurance processes require not only strategic but also technological support as well.

In technological terms, the development of a Web site for an online community presents unique challenges principally in terms of managing the interactions among users, and between users and the company. Only through efficient management of these interactions is it possible to overcome the problems arising from the trade-off between the number of members in the community and the standards of quality for the services offered. In this paper we present WebTool, an instrument we developed to support the management of a Web community – GirLand - having a large and very cohesive membership, with the consequent need to manage the growing number of interactions among them.

Most of the accessibility tools focus on designers or end-users, but few tools consider both at the same time. KAI (Kit for Accessibility to the Internet) considers designers and also users and gives blind people the possibility of having a selective access to the contents of the Internet using WebTouch, an audio/touch browser provided with the kit. KAI relies on a new language called BML (Blind Markup Language) where an element of a web page can be represented only by one tag and one tag can represent only one element. There is a tool in the kit that transforms from HTML to BML and viceversa, so that legacy sites can be accessed. KAI also provides a set of metrics so that a visually impaired user can know the accessibility degree of a web site before surfing. To our knowledge there is no tool providing together all these features. In this paper we give a short overview of KAI, and also list some of the parameters considered to build the metrics for measuring the accessibility degree of a web site from the point of view of visually impaired people.

Thus, in contrast to conventional software testing, where the focus is mainly on functionality, a wide range of quality issues are of utmost importance in testing Web-based systems. In this work, we present a systematic approach to Web testing that takes the importance of quality aspects for Web projects into account. Generally, tests can be characterized in three dimensions: quality, feature, and phase. The combination of these three dimensions results in a scheme that can be used to guide the different steps throughout the test workflow in a methodically sound and systematic way. The application of the scheme in test planning and design is demonstrated for security aspects on a sample Web application.

In this paper we analyze two possible approaches available for the storage and management of XML data (semi-structured databases and, of course, the file system). Furthermore, because we believe that the development of a standard for an XML query language will dramatically improve the usage of XML documents as an alternative means to store data, we conclude the paper with a brief reference, through examples, to some of the essential characteristics of the Xquery language.

It operates on a Web enabled environment using "free" GNU like software, open standards and "off the shelf" hardware. The framework is well suited to be operated by humanity scholars as an aid to make their assets available on the Internet. Extensive use of XML and associated technology is made.
