MDWEnet: a practical approach to achieving interoperability of model-driven web engineering methods

Current model-driven Web Engineering approaches (such as OO-H, UWE or WebML) provide a set of methods and supporting tools for a systematic design and development of Web applications. Each method addresses different concerns using separate models (content, navigation, presentation, business logic, etc.), and provide model compilers that produce most of the logic and Web pages of the application from these models. However, these proposals also have some limitations, especially for exchanging models or representing further modeling concerns, such as architectural styles, technology independence, or distribution. A possible solution to these issues is provided by making model-driven Web Engineering proposals interoperate, being able to complement each other, and to exchange models between the different tools. MDWEnet is a recent initiative started by a small group of researchers working on model-driven Web Engineering (MDWE). Its goal is to improve current practices and tools for the model-driven development of Web applications for better interoperability. The proposal is based on the strengths of current model-driven Web Engineering methods, and the existing experience and knowledge in the field. This paper presents the background, motivation, scope, and objectives of MDWEnet. Furthermore, it reports on the MDWEnet results and achievements so far, and its future plan of actions.

How the web of things challenges requirements engineering

As a subset of the Internet of Things (IoT), the Web of Things (WoT) shares many characteristics with wireless sensor and actuator networks (WSANs) and ubiquitous computing systems (Ubicomp). Yet to a far greater degree than the IoT, WSANs or Ubicomp, the WoT will integrate physical and information objects, necessitating a means to model and reason about a range of context types that have hitherto received little or no attention from the RE community. RE practice is only now developing the means to support WSANs and Ubicomp system development, including faltering first steps in the representation of context. We argue that these techniques will need to be developed further, with a particular focus on rich context types, if RE is to support WoT application development. © 2012 Springer-Verlag.

TOWARD SEMANTIC WEB SERVICES AS MVC APPLICATIONS: FROM OWL-S VIA UML

OWL-S is an application of OWL, the Web Ontology Language, that describes the semantics of Web Services so that their discovery, selection, invocation and composition can be automated. The research literature reports the use of UML diagrams for the automatic generation of Semantic Web Service descriptions in OWL-S. This paper demonstrates a higher level of automation by generating complete complete Web applications from OWL-S descriptions that have themselves been generated from UML. Previously, we proposed an approach for processing OWL-S descriptions in order to produce MVC-based skeletons for Web applications. The OWL-S ontology undergoes a series of transformations in order to generate a Model-View-Controller application implemented by a combination of Java Beans, JSP, and Servlets code, respectively. In this paper, we show in detail the documents produced at each processing step. We highlight the connections between OWL-S specifications and executable code in the various Java dialects and show the Web interfaces that result from this process.

Websislapam: sistema de avaliações de pessoas baseado em tecnologias WEB

This work, entitled Websislapam: People Rating System Based on Web Technologies, allows the creation of questionnaires, and the organization of entities and people who participate in evaluations. Entities collect data from people with the help of resources that reduce typing mistakes. The Websislapam maintains a database and provides graphical reporting, which enable the analysis of those tested. Developed using Web technologies such as PHP, Javascript, CSS, and others. Developed with the paradigm of object-oriented programming and the MySQL DBMS. For the theoretical basis, research in the areas of System Database, Web Technologies and Web Engineering were performed. It was determined the evaluation process, systems and Web-based applications, Web and System Engineering Database. Technologies applied in the implementation of Websislapam been described. In a separate chapter presented the main features and artifacts used in the development of Websislapam. A case study demonstrates the practical use of the system

Modelling adaptive web applications

Conceptual Modelling approaches for the web need extensions to specify dynamic personalization properties in order to design more powerful web applications. Current approaches provide techniques to support dynamic personalization, usually focused on implementation details. This article presents an extension of the OO-H conceptual modeling approach to address the particulars associated with the design and specification of dynamic personalization. The main benefit is that this specification can be modified without recompile the rest of the application modules. We describe how conventional navigation and presentation diagrams are influenced by personalization properties. In order to model the variable part of the interface logic OO-H has a personalization architecture that leans on a rule engine. Rules are defined based on a User Model and a Reference Model.

Applying model-driven engineering to the development of Rich Internet Applications for Business Intelligence

Business Intelligence (BI) applications have been gradually ported to the Web in search of a global platform for the consumption and publication of data and services. On the Internet, apart from techniques for data/knowledge management, BI Web applications need interfaces with a high level of interoperability (similar to the traditional desktop interfaces) for the visualisation of data/knowledge. In some cases, this has been provided by Rich Internet Applications (RIA). The development of these BI RIAs is a process traditionally performed manually and, given the complexity of the final application, it is a process which might be prone to errors. The application of model-driven engineering techniques can reduce the cost of development and maintenance (in terms of time and resources) of these applications, as they demonstrated by other types of Web applications. In the light of these issues, the paper introduces the Sm4RIA-B methodology, i.e., a model-driven methodology for the development of RIA as BI Web applications. In order to overcome the limitations of RIA regarding knowledge management from the Web, this paper also presents a new RIA platform for BI, called RI@BI, which extends the functionalities of traditional RIAs by means of Semantic Web technologies and B2B techniques. Finally, we evaluate the whole approach on a case study—the development of a social network site for an enterprise project manager.

An infrastructure for semantic web portals

This paper presents our Semantic Web portal infrastructure, which focuses on how to enhance knowledge access in traditional Web portals by gathering and exploiting semantic metadata. Special attention is paid to three important issues that affect the performance of knowledge access: i) high quality metadata acquisition, which concerns how to ensure high quality while gathering semantic metadata from heterogeneous data sources; ii) semantic search, which addresses how to meet the information querying needs of ordinary end users who are not necessarily familiar with the problem domain or the supported query language; and iii) semantic browsing, which concerns how to help users understand and explore the problem domain.

WWW-Sisällönhallintajärjestelmän kehittäminen

Tässä työssä keskitytään web-pohjaisiin sisällönhallintajärjestelmiin. Teoriaosassa käydään läpi aiheeseen liittyviä tekniikoita, web-ohjelmistotekniikan erityispiirteitä ja sisällönhallinnan käsitettä ja sen järjestelmiä. Teoriapuolella huomataan, kuinka laajaa osaa liiketoimintaprosesseista sisällönhallinta koskettaa. Siksi sen hahmottaminen on vaikeaa ja sitä voi lähestyä monesta eri suunnasta. Erilaisia järjestelmiä on lukuisia ja ne soveltuvat erilaisiin tilanteisiin. Käytännön työnä toteutetaan Codens Oy:n uuden sisällönhallinnan kehitystyö. Tavoitteena on saada huomattavia parannuksia vanhaan järjestelmään. Erityisesti kiinnitetään huomiota sivupohjasysteemiin ja käyttöliittymään, johon tuodaan mukaan web2.0:n tarjoamia uusia työkaluja. Järjestelmään saatiin useita parannuksia, mutta sen kehittämistä on vielä jatkettava, ennen kuin siitä saadaan kaupallisesti valmis tuote.

A model for analysing data portal performance: The biodiversity case

Currently, many museums, botanic gardens and herbariums keep data of biological collections and using computational tools researchers digitalize and provide access to their data using data portals. The replication of databases in portals can be accomplished through the use of protocols and data schema. However, the implementation of this solution demands a large amount of time, concerning both the transfer of fragments of data and processing data within the portal. With the growth of data digitalization in institutions, this scenario tends to be increasingly exacerbated, making it hard to maintain the records updated on the portals. As an original contribution, this research proposes analysing the data replication process to evaluate the performance of portals. The Inter-American Biodiversity Information Network (IABIN) biodiversity data portal of pollinators was used as a study case, which supports both situations: conventional data replication of records of specimen occurrences and interactions between them. With the results of this research, it is possible to simulate a situation before its implementation, thus predicting the performance of replication operations. Additionally, these results may contribute to future improvements to this process, in order to decrease the time required to make the data available in portals. © Rinton Press.

A New End-User Composition Model to Empower Knowledge Workers to Develop Rich Internet Applications

Enabling real end-user programming development is the next logical stage in the evolution of Internetwide service-based applications. Even so, the vision of end users programming their own web-based solutions has not yet materialized. This will continue to be so unless both industry and the research community rise to the ambitious challenge of devising an end-to-end compositional model for developing a new age of end-user web application development tools. This paper describes a new composition model designed to empower programming-illiterate end users to create and share their own off-the-shelf rich Internet applications in a fully visual fashion. This paper presents the main insights and outcomes of our research and development efforts as part of a number of successful European Union research projects. A framework implementing this model was developed as part of the European Seventh Framework Programme FAST Project and the Spanish EzWeb Project and allowed us to validate the rationale behind our approach.

Educational activities for a gamified system

The objective of this dissertation is to analyze, design, and implement an activity module for a larger educational platform with the use of gamification techniques with the purpose to improve learning, pass rates, and feedback. The project investigates how to better incentivize student learning. A software requirement specification was delineated to establish the system guidelines and behavior. Following, a definition of the activities in the module was created. This definition encompassed a detailed description of each activity, together with elements that compose it, available customizations and the involved formulas. The activity high-level design process includes the design of the defined activities by use of the software methodology UWE (UML-based Web Engineering) for their future implementation, modeling requirements, content, navigation and presentation. The low-level design is composed of the database schema and types and the relating EER (Enhanced Entity-Relationship) diagram. After this, the implementation of the designed module began, together with testing in the later stages. We expect that by using the implemented activity module, students will become more interested in learning, as well as more engaged in the process, resulting in a continuous progress during the course.---RESUMEN---El objetivo de este trabajo es analizar, diseñar e implementar un módulo de actividades didácticas que formará parte de una plataforma educativa, haciendo uso de técnicas de gamificación con la finalidad de mejorar el aprendizaje, ratio de aprobados y retroalimentación para los alumnos.
